Overview

Elegant 4WD Crossover for Everyday and Leisure Use

Opel is back in the four-wheel drive segment. With the new Antara, which combines dynamic, elegant design with intelligent four-wheel drive as standard, Opel is again staking a claim as leader among volume manufacturers in the SUV and crossover segment. The high-tech five-seat four-wheel drive crossover puts the looks of the three-door Antara GTC crossover concept car into series production, following their enthusiastic reception at the IAA 2005. It boasts the handling of a passenger car, generous interior space yet compact dimensions, innovative transport features such as "Flex-Fix", high levels of functionality and a raised seat position. Prices for the new Antara, which can be ordered now, start at 26,850 euros. The 4x4 is perfect for everyday and leisure-time use and will reach dealerships already this year.

Initially, three transverse engines with four valves per cylinder are available for the Antara. The most powerful is a V6 gasoline engine with a displacement of 3.2 liters and output of 167 kW/227 hp. Opel expects the 110 kW/150 hp, 2.0-liter common-rail turbo-diesel to be the top seller. Within a few months, it will be joined by a second version which produces 93 kW/127 hp. Both engines come with a maintenance-free diesel particulate filter as standard. The entry-level engine is a 2.4-liter, 103 kW/140 hp four-cylinder gasoline unit.

The Antara's intelligent four-wheel drive system combines the benefits of front-wheel drive - such as tractional stability when accelerating and increased driving dynamics - with those of permanent four-wheel drive. It features an electronically controlled electro-hydraulic differential which ensures optimal torque distribution between the front and rear axles in all situations. The drivetrain is fully integrated in the ABS and ESP systems, enhancing vehicle control and active safety.

Crossover and SUV segment has highest growth rates in Europe

Since 1998, the total share of the combined SUV and crossover market in Europe has doubled from three to six percent. An increasing number of active families, who enjoy outdoor hobbies and sports, prefer versatile, practical SUV and crossover vehicles that also look good.

With the Antara, Opel aims to play a leading role in this increasingly competitive segment, which is still growing and has long been dominated by non-European brands. In its first full year of sales in 2007, Opel forecasts up to 40,000 registrations of the newcomer in Europe, with a conquest rate of around 50 percent of buyers who have previously driven other brands.

Opel back in four-wheel drive segment

Opel already led the field in this segment before with a vehicle that stood out at the time. Unveiled in 1991, the Frontera was one of the first SUV models ever. It was number one in its segment across Europe for a number of years and was also the Opel model with the highest conquest rate. Unlike the Antara with its unibody construction, the Frontera had a ladder frame chassis typical of off-road vehicles. In total, around 285,000 units were sold in Europe up to 2003, with 37,500 sold in its peak year of 1993.

Comprehensive standard equipment ex works

A strong argument in favor of the Antara is also its comprehensive standard equipment, which boasts high-value features such as intelligent four-wheel drive with traction control, Electronic Stability Program (ESP) with Cornering Brake Control (CBC), Descent Control System (DCS), as well as Active Rollover Protection (ARP). Standard equipment also includes radio remote control central locking, air conditioning with pollen filter, front and rear power windows, electric heated/adjustable exterior mirrors, on-board info display as well as stereo CD-Radio CD 30 MP3 with remote controls on steering wheel and seven loudspeakers, and a roof-mounted antenna to ensure excellent radio reception. All Antara diesel models also feature a diesel particulate filter and electric heater Quickheat as standard.

Safety features are also extensive. The standard equipment range includes front airbags, thorax/pelvis side airbags for driver and front passenger, head curtain airbags for the front and outer rear seats, three-point safety belts and head restraints for all five seats,
seat-belt tensioners and belt-force limiters for the front seats, as well as ISOFIX mountings for fast and secure fitting of child seats with corresponding fixtures on the outer rear seats.

The Edition variant also features 17-inch alloy wheels with 235/60 R 17 tires and comfort features such as Electronic Climate Control (ECC), heated front seats and Automatic Lighting Control (ALC).

The top Antara version, Cosmo, boasts an even broader range of standard features, including 18-inch aluminum rims with 235/55 R 18 tires, leather steering wheel and gearshift knob, seats in a fabric/leather combination, on-board computer, cruise control, Park Pilot, windshield in heat-absorbing glass and rain sensor.

Optional packages for the Edition and Cosmo variants allow for even greater personalization of the Antara. The Edition boasts an on-board computer, front and rear Park Pilot, and cruise control, as well as mobile phone console with Bluetooth interface and voice control. The Cosmo package includes seats with leather upholstery, xenon headlamps with washer system and Tire Pressure Monitoring System (TPMS), as well as exterior mirrors that also fold electrically.

Other optional extras include a towing hitch, transparent electric tilt and slide sunroof, MP3-compatible stereo CD-Radio DVD Navi 100 with 6 x CD changer and mobile phone console, as well as a power adjustable driver's seat in the Cosmo variant.

Expressive design language underlines claim to leadership

As dynamic as a sporty station wagon, as robust as a classic all-terrain vehicle: at first glance, the Antara's distinctive design character is emphasized by an attractive contrast.

While the lower section clearly displays the new Opel crossover's robustness, the body's striking lines and taut surfaces unite stylish elegance with a sporty, athletic look.

Opel designers translated the Antara GTC concept's dynamic design language into a five-door, five-seat production crossover with a spacious, versatile interior. With its deliberately compact dimensions (length x width x height: 4575 x 1850 x 1704 mm), the four-wheel drive crossover takes up no more space than a mid-size passenger car.

Opel-typical details such as the crease on the hood and the grille accented by the wide chrome bar with its large Opel logo confidently emphasize the car's high quality and brand identity. Carefully crafted side air vents with integrated turn indicator in the front fender also set fresh accents.

The interior echoes the style and elegance of a top-of-the-line sedan, with contoured seats that reflect the Antara's dynamic SUV character. In typical Opel style, all instruments and operating controls are ergonomically placed and clearly laid out. Large, distinctive instruments and a center console with central info display give the cockpit a driver-oriented layout. Eye-catching interior features include three large round air vents on the center console and a distinctively shaped handbrake.

Clever, innovative: Rear carrier Flex-Fix and FlexOrganizer for luggage compartment

The Opel Antara conveys a casual, easy-going lifestyle with its spacious interior, numerous compartments, as well as many clever and practical features. The sense of spaciousness created by the elevated seating position and large glazed surfaces is superb, and the Antara doesn't just seem spacious: measurements confirm that passengers enjoy plenty of space. With 933 millimeters of rear legroom, for example, the Antara is at the top of its segment.

The trunk has a capacity of 370 liters up to the luggage compartment cover. Cargo capacity increases to 865 liters with the rear bench seat back folded down and up to 1420 liters when loaded to the roof. The rear seat back can be split 60:40 and both sections folded forward separately. With the front passenger seat also folded down (an option available from early 2007), objects up to 2.63 meters can be transported with the tailgate closed.

A storage box under the load floor ensures practical organization of the luggage compartment, as does the optional FlexOrganizer system, which is already familiar from the Astra and Vectra station wagon models. Nets, dividing walls, rods and hooks can be snapped into two rails on each of the side walls of the Antara's luggage compartment when needed.

The Antara also features numerous compartments and boxes throughout its interior, including a drawer under the passenger seat, sunglasses holder in the roof liner, nets on the front seat backs, a parking garage ticket holder left of the steering wheel, a net on the center console, compartments in the front and rear central arm rests, as well as storage boxes in the rear wheelhouses.

Available from spring 2007, the integrated rear carrier Flex-Fix boasts unbeatable practicality. Flex-Fix has the potential to set the new benchmark in flexible exterior transportation, just as the Zafira's "Flex7" does for interior seating systems. In typical Opel style, its full on-board functionality eliminates the need for cumbersome assembly, dismantling or storage of parts. Just like in the new Corsa, the integrated rear carrier stows away almost invisibly under the rear bumper and can easily be pulled out to carry up to two bicycles.

As dynamic as a passenger car with the talents of an off-roader

With its agile handling, precise speed-dependant power steering and stiff chassis, the Antara is clearly designed as a dynamic vehicle with off-road abilities. The new crossover was tuned by Opel chassis experts at various circuits, including GM test centers in Pferdsfeld, Germany and Millbrook, United Kingdom. During the development phase, the model prototypes covered over five million test kilometers worldwide.

The McPherson suspension in front and a four-link suspension in the rear provide a high-quality chassis concept similar to that of the Opel Vectra and Signum models. The Antara comes standard with 225/70 R 16 tires. The Antara Edition has 17-inch alloy wheels and the top Antara Cosmo variant 18-inch. The Tire Pressure Monitoring System (TPMS) is also available as an option.

The Antara's four-wheel drive system combines the benefits of front-wheel drive ? such as low fuel consumption and virtually effortless maneuvering ? with those of four-wheel drive. While the engine normally powers the front wheels, the propulsion power can also be quickly and seamlessly distributed between the front and rear axle at a ratio of up to 50:50 when needed. The key element for this active function is an electronically controlled, electro-magnetically operated, electro-hydraulic differential on the rear axle. The compact and light four-wheel drive system is fully integrated in the ABS and ESP systems and supports the driver effectively in all driving situations, such as during heavy acceleration.

The braking system comprises large, stable ventilated disc brakes and a modern four-channel ABS with brake assist function. The modern ESP system boasts numerous additional functions that further increase active safety, including Descent Control System (DCS), noteworthy as a standard feature in the Antara segment. DCS allows the vehicle to safely maintain a constant speed even down steep inclines without the driver needing to brake. Active Rollover Protection (ARP), another safety feature, can apply high braking pressure within milliseconds at individual wheels.

Powerful engines: Four units, output from 127 to 227 hp

A high torque plateau, plenty of traction power, durability, but all with low consumption. It is no wonder that diesel engines are in such high demand in SUV and crossover models. The Opel Antara is available with a newly-developed 2.0 CDTI engine with an output of 150 hp. A 127 hp version will be added to the range in the near future. Both engines feature newest generation common-rail technology with up to 1600 bar injection pressure, aluminum cylinder head and turbo charger with variable turbo geometry. Both variants come standard with a maintenance-free diesel particulate filter, which requires no additives. The top diesel unit can be mated to a five-speed automatic transmission instead of the standard five-speed manual gearbox.

In addition to the two diesels, the ECOTEC engine range also includes two sophisticated gasoline units. The base unit is a 2.4-liter four-cylinder engine with 103 kW/140 hp and features double overhead camshafts, a balance shaft with two rotating counterweights, as well as electronic throttle control. The most powerful engine is the 3.2-liter V6 with
167 kW/227 hp.

With its standard five-speed automatic transmission incorporating ActiveSelect, the gasoline V6, a close relative of the 2.8 V6 ECOTEC unit in the Vectra and Signum models, accelerates the Antara to a top speed of 203 km/h. This engine's high-tech features include variable camshaft phasing for both induction and exhaust sides, as well as a variable intake manifold.

All data refer to the European base model with standard equipment. The consumption data according to 1999/100/EU takes into consideration the vehicle’s curb weight as stipulated by this regulation. Additional equipment can lead to slightly higher fuel consumption and therefore CO2 exhaust emissions than the declared values. In addition, they can raise the vehicle’s curb weight and in some cases also increase the gross vehicle weight, the maximum allowable axle loads and respectively reduce the permitted trailer load. Therefore the maximum speed may be decreased while acceleration time can be increased. The published performance figures are possible with the vehicle’s curb weight excluding driver plus a 200 kilogram load allowance.

Market and Model

Antara: Full Speed Ahead in a Booming Segment

Crossover and SUV models are more popular than almost any other vehicle on the European car market. A glance at the registration statistics shows that their share of the total passenger car market has increased from just under 1.9 percent to 6.6 percent over the last ten years. Following sales of around 292,000 in 1997, an estimated 1.2 million units of the trendy all-rounders will be sold in Europe in 2006.

There is no end in sight to this growth. According to Opel marketing experts, while the rate of ascent will decline slightly, versatile crossovers and SUVs will continue to enjoy increasing popularity. This is not only true of models that are designed for heavy-duty off-road use, but also those that feature a sporty, elegant look and cut a fine figure during everyday driving. In five years’ time, it is estimated that more than 1.4 million European buyers will choose one of these all-rounders every year – accounting for a 7.4 percent share of the total passenger car market.

The new Opel Antara has everything it needs to spearhead this continuing trend. It is positioned in the mid-size crossover and SUV class, a market segment with particularly strong growth that has long been dominated by non-European brands. Now, Opel plans to become a leading player on this stage, just as the company already did for many years with a similar concept: unveiled in 1991, the Frontera was one of the first SUV models ever and dominated its segment in Western Europe for many years.

Unlike the new Antara, which features a unibody design typical of passenger cars, the Frontera had a ladder frame chassis. In Germany, it was the clear number one for five years. In total, around 285,000 units of the classic robust 4x4 were sold in Europe up to 2003.

Low entry-level price of 26,850 euros

The all-new Antara has everything it takes to rekindle this success. The attractive new Opel crossover is likely to appeal to many of today’s 160,000 Frontera owners. Opel is also confident that the Antara will attract many new customers, who will appreciate its special strengths in a competitive environment: innovative, dynamic and expressive design combined with versatile interior, quality mid-size vehicle ambiance, permanent four-wheel drive partnered with sporty, comfortable driving performance, as well as very favorable Antara prices in Germany start at 26,850 euros.

According to Opel’s market research, the new crossover’s characteristics perfectly match potential buyers’ expectations in this segment. Requirements like “comfort, driving dynamics and the functionality of a mid-size station wagon� top their wish list along with “an expressive design� and “the versatility, flexibility and all-terrain capability of an off-roader.�

Ideal partner for active lifestyle

Market researchers’ analysis shows that people who enjoy active urban lifestyles, outdoor hobbies or sports will find the new Opel crossover particularly attractive. These target groups include double-income couples over 25 without children, as well as family fathers between 35 and 40. Both groups spend a lot of time on leisure activities, which are also increasingly important to the third target group - the large market of 55 to 65-year-olds, whose children are grown up and have left home.

These buyer groups may be at different stages in their lives, but they all share certain preferences and characteristics. They are interested in attractive vehicles with innovative technology, place great importance on driving fun and versatility, and want to stand out from the crowd with their car. They often also share the intention of moving from a mid-size or compact car to an all-rounder with four-wheel drive.

High conquest rate in SUV segment

Another reason for Opel’s optimism is the fact that the Antara is the first modern crossover from a European volume manufacturer to enter the market in the mid-size SUV segment. Additionally, in view of the limited choice of comparable vehicles currently available, buyers in this segment are not known for their loyalty to their previous car brand. While an overall average of around 53 percent of customers change brands when purchasing a car, this figure is 60 percent in the SUV segment. For this reason, Opel expects additional demand for the Antara and anticipates that every second buyer will be new to Opel.

Comprehensive standard equipment ex works

Another strong argument in favor of the Antara is its comprehensive standard equipment, which boasts high-value features such as:


Safety features are also extensive, with the standard equipment range including:


The Edition variant also features 17-inch alloy wheels with 235/60 R 17 tires and comfort features such as Electronic Climate Control (ECC), heated front seats and Automatic Lighting Control (ALC).

The top Antara version, Cosmo, boasts an even broader range of standard features, including 18-inch aluminum rims with 235/55 R 18 tires, leather steering wheel and gearshift knob, seats in a fabric/leather combination, on-board computer, cruise control, Park Pilot, windshield in heat-absorbing glass and rain sensor.

Modern common-rail diesel is top choice

Opel predicts that around 60 percent of Antara buyers in Europe will choose the Edition variant, followed by Cosmo (35 percent) and the entry-level version (five percent). Marketing experts expect most buyers to select the 2.0-liter, 150 hp CDTI common-rail turbo-diesel engine, followed by the two gasoline units with 140 hp (2.4 liter) and 227 hp (3.2-liter V6).

Optional additional packages for the Edition and Cosmo variants allow for even greater personalization of the Antara. The Edition model boasts an on-board computer, front and rear Park Pilot, cruise control, as well as mobile phone console with Bluetooth interface and voice control. The Cosmo package includes seats in leather, xenon headlamps with washer system and Tire Pressure Monitoring System (TPMS), as well as heated power exterior mirrors that also fold in electrically. Other optional extras include a towing hitch, transparent electric tilt and slide sunroof, stereo CD-Radio DVD Navi 100 with mobile phone console, as well as a power adjustable driver’s seat in the Cosmo variant.

The flexible innovative integrated carrier system Flex-Fix, which just made its world premiere in the new Corsa, will be available as an option for the Antara from early 2007.

It is always available on board, easy to use, can be simply pulled out from the rear underbody like a drawer, carries for example two bicycles and completely retracts into the bumper when not in use.

Up to 40,000 new registrations expected for next year

Opel has set a European sales target for the new Antara of between 35,000 and 40,000 units for its first full sales year in 2007. The Antara will be launched in Germany, Austria and Switzerland this year and the rest of continental Europe in the first quarter of 2007. In the few remaining weeks of this year, dealerships intend to go full speed ahead with the Antara, so that it is well-positioned to take over a leading role in its segment.

Design

New Antara: In Great Shape for Any Challenge

The new Opel Antara’s origin is plain to see. Its expressive design is derived directly from the Antara GTC (Gran Turismo Crossover) concept car, the star of last year’s IAA in Frankfurt. The highly-praised design language of the off-road coupé concept car is echoed in the dynamic series production five-door crossover, underlining Opel’s claim as design leader. At first glance, the Antara’s distinctive design character is emphasized by a attractive contrast. While the lower section around the bumpers, sills and wheels clearly displays the new crossover’s robustness, the body’s striking lines and taut surfaces unite stylish elegance with a sporty, athletic look. With this fusion of sports-wagon and off-road elements, designers visualized the Antara as a versatile car that is both dynamic and comfortable for long journeys.

Typical Opel style details such as the crease on the hood and the grille accentuated by the wide chrome bar with its large Opel logo confidently emphasize the car’s high quality and brand identity. Carefully crafted side air vents with integrated turn indicator in the front fender also set fresh accents. With its compact dimensions (length x width x height: 4575 x 1850 x 1704 millimeters), the crossover takes up no more space than a mid-size passenger car.

Designers blended opposing elements on the front section to clearly underline the Antara's character, with its passenger car-like dynamic handling and rugged off-road qualities. The upper and lower halves of the bumper boast contrasting colors and, together with the distinctive underbody protector, they set off the broad gleaming chrome crossbar of the signature Opel grille. This contrast reappears at the ends of the bumper with integrated fog lamps. The darker tint flows from here over the edge of the flared wheelarches and the side sills to the rear bumper, where the eye-catching two-tone colors and underbody protector once again highlight the Antara’s robustness.

The powerfully curved hood, designed to meet new pedestrian protection standards, also adds to the Antara's dynamic look. Highlights include headlamps tapered in the lower corner that are drawn back into the fender, giving the impression the car is winking. The hood is accentuated by the typical Opel center crease as well as elegant three-dimensional contours on both sides. They blend the hood boldly with the A-pillars, harmoniously integrating the Antara’s front section into the shoulder line.

Crisp lines and exciting accents

The five-door Antara’s powerfully molded shoulder is a bold feature of its silhouette. The sporty, sloping roofline also echoes the Antara GTC concept car’s dynamic design, which earned it the title “Concept of the Year� in 2005 from the British specialist magazine “Autocar�. With a sporty downward swing, the silhouette tapers into sleek side air vents. These exciting side accents flow into lines traced by the roof railings and side windows. With their matt silver surfaces and chrome borders, both features also reflect the high quality conveyed by the Antara’s look.

This look continues to the Antara’s rear. A striking chrome crossbar not only enhances the stylish look, it also emphasizes the vehicle’s width and stability. This is underlined by the large curved rear window, which boasts frameless fitted glass that extends to the D-pillar – a design feature that also improves rear visibility and lets plenty of light into the interior. Finally, large three-dimensional rear lights set at an angle make the Antara unmistakable from the rear. Sculpted into the shoulder line, they create a smooth transition into the Antara’s profile.

Interior in luxury sedan style

The interior is reminiscent of the style and elegance of a luxury sedan. Sporty, contoured seats and a dominant center console with central info display reflect the Antara's dynamic SUV character. Attractive décor elements emphasize the Antara’s stylish interior look. Extending from the instrument panel to the doors, these elements also contribute to the sense of generous spaciousness, as does the clear layout of the instrument panel that has one or two colors, depending on the model. The upper half is always anthracite gray to prevent disturbing reflections. For the lower half, Antara buyers can opt for the same color, a friendly light beige, or a colored look to match the upholstery and door panels. The Antara’s welcoming character was created with great attention to detail and is completed by lighting that warmly illuminates the interior in the dark.

Eye-catching interior features include three large round air vents on the center console and a distinctively shaped handbrake grip. The passenger grip has the same shape but a slightly slimmer design and is also located directly adjacent to the seat, giving the “co-pilot� a firm hold, even during off-road driving.

In typical Opel style, all instruments and operating controls are ergonomically placed and clearly laid out. Large, distinctive instruments and center console with central info display give the cockpit a driver-oriented layout. Depending on the equipment variant, the 7.5-inch color screen displays all information from the navigation and audio systems, as well as all on-board computer functions.


“Good Design drives a Brand forward�

Interview with Bryan Nesbitt, Executive Director of Design, GM Europe


As Executive Director of GME Design since 2004, Bryan Nesbitt is responsible for the design of GM’s European brands Opel, Vauxhall and Saab – and most Saturn models for North America. Born in 1969 in Phoenix, Arizona, Nesbitt graduated with Honors from the Art Center College of Design in Pasadena, California and studied architecture and industrial design at the Georgia Institute of Technology in Atlanta. He has worked for General Motors since 2001. In his last assignment in the USA, he was responsible for the exterior design of all automobile and crossover models sold by GM in its domestic market. We spoke with Bryan Nesbitt about working within a global network and Opel’s design language.

Mr. Nesbitt, the Antara GTC concept car received an enthusiastic response from press and public alike at the IAA 2005. What do the concept car and the production version of the Antara have in common?

Concept cars help us explore visual solutions. Many solutions on the concept focused the design execution of the final production vehicle. We translated the GTC concept’s design language into a five-door, five-seat production crossover with a spacious, versatile interior. Many of the concept car’s style elements are recognizable in the production version, including the front fender vents, the protective cladding solution, and importantly, the front and rear graphics.

The Antara shares its architecture with other GM family models. How can you realize Opel design language in such an international environment?

An architecture is not unlike a skeleton, it’s the frame of the proportions. Fashion designers choose runway models based on proportions, not cultural origin, and we do the same.

The Opel Antara was designed in Rüsselsheim and two members of our team were on site in Korea to follow into series production.

And that ensures the brand’s identity?

Yes. Just as runway models Heidi Klum or Kate Moss can convincingly support Calvin Klein or Roberto Cavalli’s brand identity, so does a global architecture support our needs. The Antara is another example of how GM Product Development works globally. Just like a runway model, the better the architectural proportions, the more I have to work with,

You don’t see any danger of the cars becoming too similar if they share the same architecture?

No. On the contrary, the brand must always be the foundation.

GM Global Engineering provides bandwidth in the architectures to support brand identity differentiation needs. In a large organization like GM, research and product development is organized worldwide by model families and their technical architecture. Sales and marketing is organized by brands and countries. Because the designer has to bridge both of these worlds, he must always wear two hats, one for vehicle architecture and one for brand.

Is there a rulebook governing how Opel designs should look?

Targeted customers have certain expectations. However, identities necessarily evolve, so design must constantly progress, presenting an ongoing challenge for the company’s engineers and production people. Good design drives a brand forward.

Where is the Opel brand heading and how can you incorporate this direction in the design of the cars?

Opel is currently experiencing a major transformation. For example, in the Zafira and Meriva, we have created products that provide unique versatility without compromising appeal to the modern customer. These have provided the foundation for even more progressive cars, more innovative vehicle concepts, and more adventurous designs. Generally speaking, people are becoming open to fresher styling solutions, which complement Opel’s vision.

So, we can expect to see some stunning ideas.

Indeed you can. The Astra GTC, new Corsa and Antara demonstrate quite clearly how visually dynamic the Opel brand has become. We have searched for a new emotionality, which the upcoming cars will reflect. For example, early next year when you see the first Opel GT on the roads...

Given that Opel is a volume brand, does consumer acceptance place limits on how radical your designs can be?
Customers in Western Europe are very progressive in their tastes and their product expectations. There currently appears greater social acceptance in new vehicle concepts and body shapes here than, let’s say, in the USA. This provides us more freedom in some cases.

Opel has a long history in Germany. Would you describe the current Opel designs as particularly German?

The continuing globalization of brands and brand worlds means that this aesthetic definition is no longer such an important criterion for customers. Opel, and therefore Vauxhall and Saturn, are working to represent the best of European design. Europe has a wonderful history of design, strongly influenced by the Italians, but obviously also by the French and Germans.

And a final question, Mr. Nesbitt. As chief designer, do you still have the opportunity to be creative yourself or do your management responsibilities take up all of your time?

Of course. Creativity can manifest in many ways. Every function needs to be creative in their problem solving. Today my creativity is more focused on brand identity and brand portfolio. Of course I have to assemble the right teams, ensure they have a suitable working environment and respective tools, motivate and empower the staff and, of course, provide decisive visual direction. But ultimately my job is to promote maximum creativity in the context of directing the visual brand identities of Opel, Vauxhall, Saturn and Saab to appeal to their target customers.

Features

Casual and Easy-Going

The Opel Antara conveys a casual, easy-going lifestyle with its roomy interior, numerous storage compartments, as well as many clever and practical features. The sense of spaciousness is created by the elevated seating position and large windows, and the Antara doesn’t just seem roomy: measurements confirm that passengers enjoy plenty of space. With 933 millimeters of rear legroom, for example, the Antara is a segment leader.

The trunk has a capacity of 370 liters up to the luggage compartment cover. Cargo capacity increases to 865 liters with the rear bench seat folded down, and up to 1420 liters when loaded to the roof. The rear seat back can be split 60:40 and folded forward. If the front passenger seat back is also folded – this optional feature is available from spring 2007 – even objects up to 2.63 meters long can be transported with the tailgate closed.

The trunk can easily be kept tidy and organized thanks to a storage box under the floor and the FlexOrganizer system, which is already familiar from the Astra and Vectra station wagon as well as the Meriva and Zafira. Two rails are fitted as standard on each of the side walls of the luggage compartment. Nets, dividing walls, rods and hooks can be snapped into these rails as needed, allowing the trunk to be separated into different sections to protect the cargo from shifting or being damaged during the journey. FlexOrganizer components are available individually at Opel dealerships.

Cleverly designed storage options ? such as storage boxes in the rear wheelarches ? are not just available in the trunk: the Antara also boasts numerous storage possibilities throughout its interior. These include a drawer under the front passenger seat, a sunglasses holder in the ceiling, nets on the front seat backs, a parking ticket holder left of the steering wheel, a net on the center console, as well as compartments in the front and rear center arm rests, to name just a few.

The integrated rear carrier Flex-Fix boasts the unbeatable practicality that has become an Opel trademark and is especially important in the crossover segment. The flexible carrier stows away almost invisibly into the rear bumper and can easily be pulled out to carry up to two bicycles (18 to 28-inch tires). Following the system’s world premiere in the new Corsa, Flex-Fix will also be available for the Antara from spring 2007. It has the potential to set the new benchmark in flexible exterior features, just like the Zafira’s “Flex7� seating system does for interior flexibility. In typical Opel style, its full on-board functionality eliminates the need for cumbersome assembly, dismantling or storage of parts.

Numerous comfort details make life on board the Antara more enjoyable, including front and rear power windows (standard), heated front seats (standard from Edition), air conditioning (standard, Electronic Climate Control from Edition), Quickheat (standard with all diesel models), Automatic Lighting Control ALC (standard from Edition), power heated exterior mirrors (standard), exterior mirrors that fold in electrically (optional for Cosmo), power sliding/tilting sunroof (optional for Cosmo) and stationary heating (optional).

For on-board entertainment, the Antara features the MP3-compatible stereo CD-Radio CD 30 MP3 as standard. Seven loudspeakers produce an optimal sound balance in the passenger compartment, while buttons on the steering wheel are comfortable to operate.

The MP3-compatible DVD 100 Navi navigation system with radio, 6 x CD changer and mobile phone portal is optionally available. Dynamic route guidance is given on a large Color Info Display using maps and/or arrow pictograms and announcements. Latest traffic delays are displayed as Traffic Message Channel (TMC) reports on the map.

Road maps for 21 European countries are saved on the DVD, making it unnecessary to change disks, even on long journeys.

Based on the popular Marco Polo books, the integrated digital travel guide knows just about everything. In addition to the printed guide’s customary insider tips and highlights, many other topics are covered for the whole of Europe, ranging from shopping and nightlife to sports activities and amusement parks. For example, when searching for a restaurant, be it nearby or far away, the system provides much more than just the name and address. It knows the cuisine there, makes special recommendations, lists the opening hours and can even make a cost estimate for a meal.

A mobile phone portal with console on the center tunnel is also optionally available for the Antara. It features a Bluetooth connection and voice control to ensure comfortable and safe communication.

Bike Carrier

Flexible Integrated Carrier Flex-Fix: For Two More Bicycles

SUV drivers are active people ? and so belong to a group that very often has bicycles to transport. The Antara makes this especially easy – as long as it is equipped with the optional integrated carrier system Flex-Fix. Following its world premiere in the Corsa, the innovative option is also available for Opel’s crossover from spring 2007.

The idea seems straightforward, which is why it has already been around for several years: to increase passenger vehicle transport capacity by adding an integrated cargo carrier that is always available on board and disappears into the car body when not in use. Hendrik Hofmann, Opel Project Engineer, Bodyshell Product Development, knows why this intriguingly simple idea never reached series production before: "My colleagues and I put in two and a half years of intensive work to make this seemingly simple concept reality."

The team of engineers posed itself three main questions:

Packaging: How can a rear carrier be stored without affecting other vehicle functions such as crash safety and ground clearance? The conditions for this are good in the Antara, as the SUV innately has plenty of ground clearance and its spare tire is stored in the luggage compartment. And because Flex-Fix also had to fit in the new Corsa, the carrier has compact dimensions: folded up, it is 80 millimeters high and 700 millimeters long.

Functionality: How can Opel ensure that the carrier operates safely in all weather conditions ? even after hours of driving on gravel roads in Sweden or during a sudden snowstorm in the Alps?

During extensive testing, the engineers assessed the system’s functionality and were even more motivated by the results: “You should have seen the astonished faces of our colleagues from other brands when we pulled our carrier out of the car’s completely snow-encrusted rear during winter test drives,� says Hofmann, still smiling today. Other aspects of everyday use were also carefully thought through. For example, the Flex-Fix carrier’s unlocking lever is located in the right side-panel trim of the luggage compartment, ensuring easy access even when the trunk is full.

Long-term durability: How can Opel ensure the Flex-Fix will still operate reliably in years to come? In contrast to non-brand carriers from accessory stores, Flex-Fix is an integral part of the Antara, so the system must conform to Opel’s strict requirement that it last the car’s lifetime. “Our rear carrier is designed for a maximum load of 40 kg and weighs
23.5 kg itself. With a little technical imagination, it’s easy to understand just how intense the dynamic pressure on the lever arms can become while traveling on uneven roads,� says Hofmann, outlining the problem that had no text book solution – a common predicament of innovation.

So the engineers mounted a carrier prototype to a test vehicle, fitted the anchor points with sensors and subjected the car to endurance tests at GM/Opel's roughest tracks in Dudenhofen. The resulting data were analyzed and transferred to a special program for hydropulse testing at the Rüsselsheim development center. From then on, each new enhancement could be screened for durability at the laboratory.

The Flex-Fix team also made no compromises when it came to corrosion protection. The integrated carrier's steel parts are not only galvanized, but are also primed via cataphoresis and protected by a resilient topcoat to even withstand years of gravel and road salt, as proven by extensive testing. In addition, the pull-out carrier’s interlocking components are Teflon-coated.

Body and Safety

Robust with Plenty of Space and High Safety Reserves

The increasing popularity of SUV and crossover vehicles is not just a result of the strong figure they cut on the road and their off-road capabilities. The feeling of safety from the high, straight seating position as well as the sense of generous space also plays a key role.

The new Antara’s roomy body meets these expectations despite its compact exterior dimensions (length x width x height: 4575 x 1850 x 1704 millimeters), while the interior and luggage compartment size position the newcomer among the leaders in this segment.

SAFETEC: Integral safety system

In typical Opel style, the Antara’s integral SAFETEC system encompasses all relevant active and passive safety systems that contribute to reducing dangers during driving and real-life collisions. With its extensive standard equipment such as intelligent active four-wheel drive, a modern chassis with ABS, ESP with Cornering Brake Control (CBC), Active Roll-over Protection (ARP), Descent Control System (DCS) and hydraulic brake assist, the new Opel Antara boasts high active safety reserves. And if a collision cannot be avoided, an extensive package of passenger-oriented passive safety features reduces the risk of injury to all Antara occupants.

The Antara’s stiff bodyshell ? high strength steel is used for over 37 percent of the structure ? protects the “safety cell� for passengers. Side, cross and front wheel carriers distribute impact forces along a total of three load paths in the event of a frontal collision, minimizing the effects of impact on the interior. The doors are reinforced in the middle and upper sections, stiffening the whole vehicle structure.

The doors also serve as side impact protection, as do B-pillars produced from tailored blanks. With these “tailor-made� components, the strength of the body paneling varies in defined places, depending on the structural element's potential subsequent load. The reinforced rear with large side members and fuel tank situated in front of the rear axle facing the direction of travel complete the body's accident protection measures. Special crashboxes in the front and rear body frame absorb impact energy and help to keep repair costs down in the event of a low-speed accident.

Extensive protection measures for driver and passengers

Driver and passengers all benefit from an extensive package of protection measures in the Antara. Standard equipment for on-board passive safety includes:


ISOFIX anchor points: Safe and quick mounting of child seats

Antara designers also put child protection high on their list of safety priorities. To this end, the rear doors both have child locks and the outer rear seats feature ISOFIX anchor points for quick and safe mounting of child seats.ISOFIX is a child seat standard set by the International Organization for Standardization, and consists of two fixtures between the seat back and seat surface that are anchored to the car structure. An additional top tether prevents the child seat from rotating.

Powertrain

Powerful, Efficient and Intelligent

Powerful and economical: when it comes to SUV and crossover models, diesel engines are first choice in Europe. That is why Opel expects the 110 kW/150 hp, 2.0-liter common-rail turbo-diesel to be the top seller. Within a few months, it will be joined by a second version, which produces 93 kW/127 hp. Both diesel engines come with a maintenance-free diesel particulate filter as standard. The entry-level engine for the Antara is a 2.4-liter, 103 kW/140 hp four-cylinder gasoline unit with double overhead camshafts and a balance shaft with two rotating counterweights. The most powerful engine is the 3.2-liter gasoline V6 with 167 kW/227 hp. All engines are transversally mounted, feature four-valve technology and are coupled to a five-speed manual transmission as standard - except the V6, which comes with an also newly designed five-speed automatic gearbox ex works (transmission available as an option for other engines). Alternatively, a newly designed five-speed automatic gearbox is available (standard with V6). Its ActiveSelect function also allows manual gear shifting and the winter program facilitates driving, on slippery roads.

The intelligent active four-wheel drive system ITCC (Intelligent Torque Controlled Coupling) is fitted as standard and combines the benefits of pure front-wheel drive ? such as low fuel consumption and virtually effortless maneuvering ? with those of four-wheel drive. While the Antara is a front-wheel drive car under normal conditions, drive can be quickly and seamlessly distributed between the front and rear axle at a ratio of up to 50:50 when needed. The four-wheel drive system’s principal component is an electronically controlled electro-hydraulic differential on the rear axle.

The four-wheel drive system is compact, light and fully integrated in the ABS and ESP control systems. To effectively isolate the body from the engine, the Antara features a complex four-point pivoted bearing in the neutral axis. With this Neutral Torque Axis (NTA) mounting, the engine’s weight is supported by bearings located left and right in its dynamic spin axis. This mounting reduces vibrations and noise, especially when the engine is idling.

Powerful, economic and clean diesel engines

A high torque plateau, plenty of propulsion power and durability, but low consumption. No wonder diesel engines are in such high demand in SUV and crossover models. The Opel Antara is also available with a newly developed 2.0 CDTI engine with an output of 150 hp. A 127 hp version will be added to the range in early 2007. Both engines feature newest-generation common-rail technology with up to 1600 bar injection pressure, aluminum cylinder head and turbocharger with variable turbo geometry.

Both variants come standard with a maintenance-free diesel particulate filter, which requires no additives. The exhaust-gas cleaner consists of a solid, honeycomb-shaped ceramic body with microscopic channels. Soot particles collect on the surface of these channels and are regularly burnt off to prevent the filter blocking. Instead of using a complex system of fuel additives to remove these particles, multiple targeted injections raise the diesel engine’s exhaust-gas temperature to 600 degrees Celsius ? the soot particulate’s ignition temperature ? for the duration of the burning process in the filter.

The top diesel unit can be mated to a five-speed automatic transmission instead of the standard five-speed manual gearbox. In both cases, it delivers excellent propulsion power. Accelerating from 80 to 120 km/h in fifth gear takes only 12.6 seconds (automatic: 9.7 seconds). According to MVEG-mix data, consumption is only 7.5 liters of diesel per 100 km (automatic: 8.6 l/100 km). In combination with the 65-liter fuel tank, this provides an operating range of around 870 kilometers. Top speed is 180 km/h (automatic: 178 km/h).

The new diesel engine was co-developed by GM Korea and GM Powertrain, and is produced in Gunsan, South Korea. Up to 250,000 engines can be produced annually in the 19,200 square meter plant, where regular production began in March 2006.

Gasoline engines: Refined and powerful

In addition to the two diesel units, the ECOTEC engine range includes two refined gasoline units. The base unit is a 2.4-liter four-cylinder engine with 103 kW/140 hp. The long-stroke engine (bore/stroke: 87.5/100 millimeters) features technical details such as double overhead camshafts, a balance shaft with two rotating counterweights and an electronic throttle control. The 2.4-liter Antara reaches a top speed of 175 km/h, accelerates from zero to 100 km/h in 11.9 seconds, and requires 9.6 liters of fuel per 100 km (MVEG-mix).

The most powerful engine is the 3.2-liter V6 with 167 kW/227 hp. With its standard five-speed automatic transmission with ActiveSelect function, the six-cylinder gasoline unit ? a close relative of the 2.8 V6 ECOTEC unit in the Vectra and Signum ? accelerates the Antara to a top speed of 203 km/h. This engine's high-tech features include variable camshaft phasing for both induction and exhaust sides, as well as a variable intake manifold.

The ultra-modern all-aluminum engine belongs to a V6 range that was developed in close co-operation between GM Powertrain engineers in North America and their European and Australian colleagues. In addition to the six-cylinder naturally-aspirated engines with displacements of 2.8 to 3.6 liters, this collaboration also produced a turbo variant, which is available in the Vectra and Signum.

Besides the Vectra, Signum and Antara, other GM cars that benefit from the dynamic driving performance and fuel efficiency of these engines include the Cadillac CTS, several U.S. Buicks, the Saab 9-3 Aero, and many Holden models. In each case, the units are carefully tuned to meet the needs of the specific brand.

Global co-operation in developing and producing these engines enables an up to 90 percent share of identical components. To allow these engines to be used globally, they were designed to meet many market demands around the world. For example, they feature valve timing to ensure optimal power delivery and emissions performance for the prevailing traffic and climate conditions. The intelligent base design of GM’s new V6 model range is further proof of its versatility and global application possibilities. It allows engines to be mounted transversely or longitudinally, while accommodating variants with direct injection, manifold injection and turbo charging. In total, the ultra-modern six-cylinder engines cover a performance and torque range of 203 to 320 hp and 267 to
485 Nm.

Transmissions for shifting-comfort and high torque

The all-new five-speed manual transmission is available for the first time in the Antara. The compact three-shaft gearbox can deliver torque of up to 330 Nm, and gear changes are especially smooth and quiet thanks to the use of carbon fiber material in the synchromesh. The 2.4-liter entry-level gasoline variant is available only with this transmission.

The 2.0 CDTI with 150 hp can also be coupled with a new five-speed automatic gearbox, which is also designed to deliver torque of up to 330 Nm. Including automatic transmission fluid, the compact unit weighs just 91 kilograms. The 3.2-liter V6 features this transmission as standard.

Intelligent, active and lightweight four-wheel drive system

All Antaras feature the modern four-wheel drive system ITCC (Intelligent Torque Controlled Coupling). Key elements are one electromagnetic pilot coupling and one hydraulic wet multidisk clutch. ITCC is electronically controlled and variably distributes propulsion power between the front and rear axles. The advantages of this design compared to conventional ones are that it is maintenance-free, compact and light. The system reacts immediately and also prevents wind-up in the transmission, which can occur with a rigid axle connection. The low weight is also beneficial, as the essential components ? Power Transfer Unit (PTU), drive shaft, rear axle shaft, Rear Drive Module (RDM) and couplings ? weigh just 75 kilograms altogether.

The four-wheel drive system operates by constantly receiving data via the high-speed CAN databus from the Electronic Stability Program (ESP) about the number of revolutions of each wheel, steering angle and accelerator pedal position. This information is continuously analyzed. Under normal conditions, all propulsion power is distributed to the front wheels and the rear axle clutch is therefore open. However, if the electronics recognize a need for action due to altered traction conditions, the torque is distributed seamlessly between the front and rear axle within 100 milliseconds. All propulsion ratios between full front-wheel drive and 50:50 distribution to both axles are possible.

To activate the rear axle, the control unit directs electricity to the electromagnetic pilot coupling’s magnetic coil. The resulting magnetic field activates an armature in the coupling. A ball-ramp system acts as an additional power booster, while compressing the wet multidisk clutch. The higher the pressure on the main coupling, the more power is distributed to the rear axle.

Chassis

A Star Both On and Off the Road

With its agile handling, precise speed-dependent power steering, firm, electronically networked chassis and active four-wheel drive, the Antara is designed for primarily on-road use. The new crossover was tuned by Opel chassis experts on various roads, including GM test centers in Pferdsfeld and Dudenhofen in Germany, as well as Millbrook in the United Kingdom. During development, the prototypes covered over five million kilometers worldwide. The Antara boasts additional dynamics, comfort and active safety thanks to the CAN Bus networking of all driving dynamics systems, such as ABS, Cornering Brake Control (CBC), ESP, Active Rollover Protection (ARP), Traction Control (TC), Descent Control System (DCS) and electronically controlled four-wheel drive differential.

The McPherson strut suspension in front and a four-link axle in the rear are similar to the chassis concept of the Opel Vectra and Signum models. The unusually long wheelbase (2707 mm) and wide track (front/rear 1562/1572 mm) are also key factors in the Antara’s dynamic and comfortable handling.

Active four-wheel drive system ensures traction

The Antara’s intelligent four-wheel drive system activates the rear wheels quickly and seamlessly via an electronically controlled differential for optimal traction when needed. Under normal conditions, the Antara is purely a front-wheel drive car.

However, if the electronic control unit detects a need for more traction, for instance on a slippery road, drive can be distributed between the front and rear wheels at a ratio of up to 50:50. Key elements are two clutches ? one electromagnetic pilot and one hydraulic wet multidisk. In addition to monitoring wheel slip, the system’s electronic central unit also processes a range of other information such as accelerator pedal position, engine rpm, vehicle speed, yaw rate and steering angle.

Dynamic and agile despite high ground clearance

The new Opel Antara’s front suspension is mounted on a stable subframe which ensures precise wheel alignment and high lateral rigidity. Large-capacity damping elements isolate the front axle and steering from the body, keeping vibration and road impact well away from the vehicle interior. The compact four-link rear axle uses three transverse and one longitudinal link. During tuning, Opel chassis engineers managed to prevent typical SUV body roll while enabling a high level of agility and also ensuring a comfortable ride. These characteristics were achieved in various ways, including springs integrated into the suspension struts on the front axle, which enhance roll-prevention without detracting from comfort.

Hydraulic assistance to the rack-and-pinion power steering is speed-dependent, enabling light steering during maneuvering. At an overall steering ratio of 16.43:1, this creates an agile and direct steering response, which is enhanced by a very light magnesium steering wheel. The steering column’s angle can be adjusted by plus or minus 2.3 degrees and its reach by 40 millimeters.

Thanks to its high ground clearance of 200 millimeters, the Antara also cuts a fine figure during off-road driving, even when its path seems to be blocked by water. It has no trouble crossings fords up to 450 millimeters deep. Overhang angles of 24 degrees in front, 23 degrees at the rear and a ramp angle of 18.2 degrees also make it well-equipped for light off-road driving.

Leveling system optimizes ground clearance, even when loaded or towing trailer

The four-wheel drive system that benefits the Antara during off-road driving also ensures optimal traction when towing a trailer.

In addition, the Antara 2.0-liter CDTI is equipped with a leveling system as standard: instead of the conventional shock absorbers, a regulating system with a pump integrated in the shock absorbers, reservoir, sensor, control mechanism and damper is fitted at both rear wheels and automatically adapts the Antara to cargo loads.

The pump increases pressure until the car reaches its normal height. Body side roll and damping behavior during driving are the same as an unloaded vehicle. This advantage in active safety is also particularly relevant when towing a trailer (up to 2000 kg).

From spring 2007, the Antara will also be available with Trailer Stability Program (TSP), which has a yaw-rate sensor that immediately detects any yawing tendencies in the car-trailer combination and automatically stabilizes it again with brake intervention or by closing the throttle.

16 to 18-inch wheels, optional Tire Pressure Monitoring System

The Antara comes with 16-inch wheels and 215/70 R 16 tires as standard. The Antara Edition has 17-inch alloy wheels and the top Antara Cosmo variant 18-inch alloy rims. The Tire Pressure Monitoring System (TPMS) is also available as an option. It monitors tire pressure via sensors at each tire valve and activates an individual tire warning signal in the info display at pressure losses as of 0.3 bar. The display can show the exact pressure of all four tires to within 0.1 bar.

The braking system comprises ventilated disk brakes and a modern four-channel ABS system. The ABS hydraulics also takes over the brake assist function if emergency braking occurs (Hydraulic Brake Assist, HBA). The ESP system boasts numerous additional functions that further increase active safety. The Active Rollover Protection (ARP), for example, is specially tuned to SUV conditions and can apply high braking pressure within milliseconds at individual wheels.

Top safety even down steep slopes with Descent Control System

The ABS and ESP sensors are also used by the Descent Control System (DCS), which -unusually for this segment - is standard in the Antara. DCS enables the vehicle to safely maintain a constant speed even down steep slopes without the driver needing to brake.

During winter holidays on snow-covered village roads, for instance, the system ensures that the car does not exceed a pre-selected speed, thereby remaining easy to control. It operates at speeds of up to 50 km/h.

If the driver selects first gear while stationary (or "D" for automatic) before a steep slope, allows the vehicle to roll forward without using the accelerator pedal, and then presses the DCS button, the system will maintain a maximum downhill speed of 10 km/h and keep this speed constant through brake intervention at the front wheels.

If the Antara is approaching a steep downhill slope at a certain speed in a gear higher than first (also valid for automatics), the driver can activate DCS by operating the brake pedal as the vehicle starts to descend. The system then reduces the vehicle’s speed to 15 km/h and maintains this speed to the bottom of the slope. DCS also operates in reverse gear. In this case, a constant 8.5 km/h is maintained.

It is also possible to accelerate or decelerate slightly when driving down a slope with DCS activated. When the driver removes his foot from the accelerator or brake pedal, the system returns the vehicle to its pre-selected speed. If the system is activated at a significantly higher speed, the braking effect is immediately noticeable. At the same time, a clearly audible sound informs the driver about the activities of the ESP system’s hydro control unit, which regulates the instant brake intervention.

Electronic Assistants

They are not just called ABS and ESP. but also CBC, HBA or TCS – to name but a few of the new Opel Antara’s numerous driver assistant systems. The following overview shows what these electronic control systems do and how they assist drivers in critical situations: Click here for chart below
















Feature

Function

Operation

ABS
Anti-lock Braking System

Prevents wheel lock-up during maximum braking, thereby ensuring steering control

If a wheel begins to lock up during braking, the ABS control unit automatically reduces braking pressure on the corresponding
wheel-brake cylinder until wheel slip returns to normal.

ARP
Active Rollover Protection

Prevents build up of body roll waves, which can lead to rollover

If ARP detects quick steering movements typical of avoidance maneuvers, the system brakes at the front outside wheel. This reduces lateral acceleration and speed, stabilizing the car.

CBC
Cornering Brake Control

Optimizes braking distance and driving stability when braking in curves

When wheel sensors register different rpm right and left in a curve, braking force on inner wheels is reduced when brake pressure is applied under the ABS limit. This creates torque that stabilizes the vehicle.

DCS
Descent Control System

Maintains constant pre-selected speed on downward, unpaved slopes

As soon as DCS is activated, it monitors the vehicle’s speed with the help of ABS sensors and brakes automatically, enabling a controlled descent at constant speed without locking the wheels.

Operation

ESP
Electronic Stability Program

Prevents break-away when driving at speed in curves or during avoidance maneuvers

With the help of sensors, ESP determines rpm, steering angle, yaw velocity and lateral acceleration. This compares driver’s intentions with driving condition. Should critical driving situations occur, the system intervenes in engine electronics and with selective braking at each wheel to return vehicle to stable driving condition.

HBA
Hydraulic Brake Assist

Automatically builds up maximum brake pressure in critical situations even when driver does not apply full pressure to brake pedal

Within a split second, full braking force is available in the brake booster if the brake pedal is pressed especially quickly and forcefully.

TCS
Traction Control System

Prevents wheel spin on driving wheels

If one of the car’s drive wheels is on solid and the other on slippery ground, one wheel will tend toward wheelspin when driving off. TCS automatically brakes the wheel with traction problems until the second drive wheel can transfer enough torque to drive off.

Quality and Economy

Integral Approach to Quality

Pleasing results in numerous tests confirm the success of Opel’s quality initiative and is in line with the integral approach to quality adopted by GM manufacturers worldwide. The new Opel Antara, which is manufactured at GM Korea, also benefits from the strategy of maintaining highly developed globally consistent standards. The “GM Global Manufacturing System� (GM GMS), implemented throughout the world, is based on five key concepts: "zero defects policy", standardization, continuous improvement, short cycle times and workforce involvement.

New models undergo demanding durability testing long before series production begins.

During the new SUV’s development phase, for example, prototypes and preproduction models covered over five million test kilometers on testing grounds and tracks worldwide. The German GM/Opel test centers in Dudenhofen and Pferdsfeld played a central role in the Antara’s chassis tuning.

In addition to these tests, it is often a combination of material and workmanship details that create an Opel model’s high-quality look, because the car should also appeal to the driver’s – and passengers’ – senses. The new Antara’s good looks are eye-catching from any perspective.

The crossover also sounds good, for example when the doors close with a satisfying click. And it feels good, because the materials are pleasing to the touch and all turn-button movements are precise and well-defined.

A team of scent experts even successfully developed the new Antara’s olfactory qualities. All interior components were analyzed and optimized at the central laboratory in Rüsselsheim, resulting in a pleasant scent without odors from plastic parts. The scent experts were recently able to confirm their work’s success in Antwerp in the very first Antaras that were delivered.

Plenty of Opel know-how also went into the Antara’s repair-friendly design. Drivers profit from this in several ways: through low workshop costs, short down times and favorable insurance premiums.

Construction details that help minimize costs for minor front and rear damage include easily replaceable bolted subframe radiator supports, bumper fascias that can be changed quickly, and a special repair feature for headlamp mounting brackets. If a headlamp’s plastic holder tears during a minor collision, the headlamp does not necessarily need to be replaced. For such cases, Opel offers a special repair set with a new holder for the Antara, as it does for other models.

Relatively expensive engine components, such as radiator and air conditioning condenser, are well protected behind generously proportioned impact force limiters. The bumpers also boast large impact surfaces, and energy absorption is completed by bolted crash boxes arranged behind them. Should an accident occur, a repair method specially developed for the Antara also keeps costs down and enables partial replacement of the vehicle floor if needed.

In addition, Opel employs preventative measures in other areas, such as full galvanization of all body sections prone to corrosion. And the new Antara will seldom see the inside of a workshop, thanks to inspection intervals of 15,000 kilometers or one year, as well as many completely maintenance-free components. These include a maintenance-free diesel particulate filter in the diesel models, hydraulic valve lifters in the valve operation of the 2.4-liter gasoline engine, as well as the camshaft’s chain drive and hydraulic valve clearance adjusters in the 3.2-liter six-cylinder gasoline unit.

The warranty is also generous: in addition to the 24-month new-car warranty including Mobile Service, Opel offers a 12-year anti-perforation warranty for the Antara, as well as a three-year warranty for the Opel starter battery.

Glossary of Technology and Innovations

ABS (Anti-lock Braking System)
If a wheel or wheels begin to lock up during full braking, the ABS control unit automatically reduces braking pressure on the relevant wheel brake cylinder until wheel slip returns to normal.

Active Four-Wheel Drive System ITCC (Intelligent Torque Controlled Coupling)
Quick and seamless activation of rear wheel drive via electronically controlled differential for optimal traction when needed. Under normal conditions, the Antara is purely a front-wheel drive car. However, if the electronic control unit detects a need for more traction, for instance on a slippery road, up to 50 percent of all propulsion power can be distributed to the rear wheels. Key elements are two couplings ? one electromagnetic pilot coupling and one hydraulic wet multidisk coupling. In addition to monitoring wheel slip, the system’s electronic central unit also processes a range of other information such as accelerator pedal position, engine rpm, vehicle speed, yaw rate and steering angle.

ActiveSelect Function (Automatic transmission)
Gear lever on the automatic transmission can be moved across to a second gate in which manual shifting is possible by lightly tapping the lever.

ALC (Automatic Lighting Control)
In response to readings received from two sensors in the windshield, ALC automatically activates or deactivates the low beam headlamps. One sensor measures ambient brightness, while the other takes into account lighting conditions on the road ahead of the car, thus recognizing tunnels or bridges. Should both sensors register darkness (e.g. at night), the low beam headlamps are automatically switched on. If darkness is registered ahead of the car and brightness in the surrounding area (e.g. entering a tunnel), the low beams are also activated. If the forward light sensor measures brightness and the ambient area sensor darkness, this indicates a bridge or underpass and the headlamps remain deactivated. When both sensors again detect brightness, the headlamps are switched off following a brief time lag.

AQS (Air Quality Sensor)
Part of the air conditioning system, this sensor detects gases such as fuel vapor via chemical reactions on its surface and automatically activates air circulation. Unlike conventional air quality sensors, the AQS system operates dynamically. Through constant monitoring of air quality in the car and outside, the system determines whether to open the vents and refresh the interior, or keep them closed.

ARP (Active Rollover Protection)
System prevents excessive body roll even before the ?ESP sensors register any danger. Thanks to additional software, ARP can detect sudden steering movements typical of avoidance maneuvers. By braking at the outer front wheel, the system reduces lateral acceleration and speed.

Auto Lock
Locks the car automatically as soon as a speed of 40 km/h is reached.

Brake Assist
This sub-function of the two-stage brake booster progressively generates maximum braking pressure when the brake pedal is pressed particularly quickly and firmly, thus reducing braking distance.

CAN Bus (Controller Area Network)
Network of a number of ?Databus systems with various transmission speeds.

CBC (Cornering Brake Control)
Optimizes braking distance and driving stability, also when braking in curves. When wheel sensors register different rpm right and left in a curve, braking force on inner wheels is already reduced when brake pressure is applied under the ABS limit. This creates torque that stabilizes the vehicle.

Crashbox
This element is located between the bumper cross members and the body. Due to its design and construction, the crashbox has energy-absorbing deformation properties that prevent costly damage to supporting components in the event of mild collisions. The bolted-on crashboxes can be replaced easily and inexpensively.

Databus
Various electrical and electronic components are connected by one common databus conductor. These series-connected modules are capable of recognizing commands specifically intended for them. Advantages: larger data volume, higher transmission speed, lower weight, greater reliability. ?CAN Bus

DCS (Descent Control System)
System regulates speed on downward slopes with the help of ABS sensors, and brakes automatically to allow a controlled descent without wheel lock.

Door-to-Door-Illumination
Headlamps continue to shine for 30 seconds after the vehicle has been turned off and exited to provide illumination.

Double-DIN Format
The clearly arranged control panel for the audio and infotainment systems is twice as large as a standard unit. Advantages: easy-to-operate controls and more space for the integration of additional equipment such as a telephone and CD changer.

EBD (Electronic Brake Force Distribution)
Individually distributes brake pressure at each wheel to ensure optimum stopping distance.

ECC (Electronic Climate Control)
The driver need only set the desired temperature on this electronically regulated air conditioner. The user-friendly system then regulates cooling capacity and air flow by itself. Assisted by a mathematical model and information from numerous sensors as well as highly complex software, the powerful Opel climate control processor calculates interior temperature developments and reacts, for example with cooler air, before the temperature in the car actually changes.

E-Gas
Electronically controlled throttle valve.

ESP (Electronic Stability Program)
Newest generation driving stability system with selective brake application at up to all four wheels.

“Flex-Fix� Integrated Rear Carrier
The “Flex-Fix� integrated rear carrier is available for the Antara from spring 2007. It stows away almost invisibly into the rear bumper and can easily be pulled out as needed to carry up to two bicycles (18 to 28-inch tires). Even the required additional rear lights are stored in the drawer-like carrier and can be fitted quickly.

FlexOrganizer System
Flexible luggage compartment management system with two parallel rails that extend to the rear bench seat on both side walls. Using nets, dividing walls, rods and hooks that can be snapped into the rails when needed, the luggage compartment can be configured to meet any transport requirements.

GPS (Global Positioning System)
Geostationary system of 29 active satellites. With the help of GPS, the navigation system determines the current location of the car and calculates the route to the destination based on a digital map. This map is either on a CD-ROM or DVD.

Head Curtain Airbags
These latest-generation head curtain airbags provide additional protection for passengers in the front and rear on both sides of the vehicle. They deploy within 25 to 30 milliseconds, forming a curtain along the entire inner side of the car. In the event of a side collision, they protect the heads of the passengers on the collision side and, at the same time, reduce the risk of injury from glass splinters.

MP3 Player
MP3 stands for "Motion Pictures Experts Group Audio Layer 3", a process which permits the compressed storage of audio data without negatively affecting the sound. Thanks to the high level of compression, a full ten hours of music instead of the usual 70 minutes can fit onto a CD-ROM.

Park Pilot
This acoustic parking aid employs ultrasonic sensors located in the Antara’s front and rear bumpers to alert the driver with an audible warning signal if there is an object in the car’s path. The sensors send out and receive sound waves, calculate the distance to the object and then emit an acoustic warning signal if clearance falls below a predetermined distance. When the Antara is fitted with Flex-Fix and the rear carrier extended, the system recognizes that the car is longer than usual.

Quickheat
Innovative heating system in which an electric auxiliary heater prevents windows from fogging up and speeds up interior warming. It activates automatically when the “maximum heating� setting is selected due to low outside and engine coolant temperatures. Standard in all diesel models.

RDS Radio (Radio Data System)
Radios equipped with this decoder receive digital information such as the name of the current program or traffic messages. All Antara infotainment systems come equipped with RDS.

TC (Traction Control)
Ensures that propulsion power is transferred with minimal tire slip. If one of the car's drive wheels is on solid and the other on slippery ground, one wheel will tend toward wheelspin when driving off. TC automatically brakes the wheel with traction problems until the second drive wheel can transfer enough torque to drive off.

Thorax/Pelvis Side Airbags
Installed in the backs of the front seats, these voluminous and form-optimized side airbags with two air chambers protect both the upper body and pelvic area.

TPMS (Tire Pressure Monitoring System)
Sensors monitor pressure at the tire valves and activate a warning signal if pressure drops.

TSA (Trailer Stability Assist)

Reliably prevents unstable driving conditions when towing (e.g. a trailer). The system constantly monitors the yaw rate of the towing car and immediately detects any yawing tendencies. By closing the throttle and applying the brakes, the car-trailer combination is automatically stabilized (optionally available from spring 2007).
