Short story

 

Mercedes-Benz is now offering significantly greater comfort and driving dynamics in the C, CLK, CLS, and E-Class with a total of eight new six-cylinder models. The engine offensive is based on all-new V6 petrol and diesel engines that are the best in their displacement class in terms of power output, torque, fuel consumption and environmental friendliness. Another new arrival is the E 420 CDI, whose eight cylinder engine delivers 231 kW/ 314 hp, making it one of the most powerful passenger-car diesel engines in the world. Mercedes-Benz is also offering four new engine variants for the CLK-Class and has upgraded both the coupe and cabriolet versions by redesigning the front end and implementing numerous technical innovations that ensure even greater safety and comfort. In addition, the CLK cabriolet, the CLS-Class four-door coupe, and the 4MATIC version of the E-Class are now available for the first time ever with V6 diesel engines.

The new CLK 280, CLK 350, and CLK 320 CDI six-cylinder models have made the CLK-Class even more powerful and sporty than ever before. This improvement is also reflected in the dynamic appearance of coupe and cabriolet, which feature a redesigned front bumper with a striking wedge shape and larger air intakes, as well as a modified radiator grille with three louvers. In future, the CLK's AVANTGARDE equipment line will feature 17-inch five-double-spoke light alloy wheels as standard, while the ELEGANCE line will have nine-spoke light alloy wheels (16 inch; 17-inch wheels for the CLK 320 CDI and up).

As part of the model upgrade, Mercedes designers have also enhanced the interior of the CLK-Class with their traditional attention to detail, and made the various equipment lines even more distinct. For example, the AVANTGARDE models now come with a new instrument panel featuring an aluminium faceplate, white dials and chrome rings. In addition, the discreet elegance of the ELEGANCE line has now been further reinforced through a new fabric pattern, new leather coverings (optional), and new ash wood trim.

Mercedes-Benz is also fulfilling the wish of many drivers for even more sporty touches by offering a new Sport Package and Sport Package AMG, which include 18-inch light alloy wheels, 225/40 R 18 (front) and 255/35 R 18 (rear) broad tyres, perforated brake disks and a sport chassis.

The engine line-up for the CLK coupe will in future include a tried-and-tested four-cylinder diesel engine delivering 110 kW/150 hp, which needs only 6.4 to 6.5 litres of fuel to travel 100 kilometres.

E-Class: New top diesel model with an output of 231 kW/314 hp

Customers who purchase the Mercedes E-Class will have 27 engine and body variants to choose from in future. Five of the engines are completely new � two six-cylinder CDI units, two V6 petrol engines and, beginning in the autumn of 2005, a new V8 diesel engine. Mercedes-Benz has also expanded its range of four-wheel-drive vehicles to include the new E 280 4MATIC and E 350 4MATIC. These will be joined in future by the E 320 CDI 4MATIC.

The E 420 CDI has a newly developed eight-cylinder diesel engine that delivers 231 kW/ 314 hp and provides a maximum torque of 730 Nm from just 2,200 rpm. This engine feature guarantees exemplary elasticity when overtaking, as well as during rapid sprints. It also ensures relaxed driving in high gear. The E 420 CDI accelerates from zero to 100 km/h in 6.1 seconds and from 60 to 120 km/h in only 5.4 seconds in third gear. This top-of-the-line diesel vehicle, which consumes 9.3 litres of fuel per 100 kilometres (combined), comes with a maintenance-free particulate filter, a seven-speed automatic transmission, AIRMATIC suspension and numerous other features as standard equipment.

CLS-Class: Four-door coupe with new diesel power

Along with the powerful petrol engines delivering 200 kW/272 hp and 225 kW/306 hp � and the CLS 55 AMG (350 kW/476 hp) � the CLS-Class model programme will in future also include the new CLS 320 CDI with a V6 diesel engine delivering 165 kW/224 hp. Like all other CLS-Class engines, the new six-cylinder diesel also comes with the new seven-speed 7G-TRONIC automatic transmission as standard equipment.

The combination of the four-door CLS coupe with the new V6 diesel engine will provide a driving experience that's sure to thrill motorists in terms of comfort and driving dynamics. The CLS 320 CDI accelerates from zero to 100 km/h in 7.0 seconds and reaches a maximum speed of 246 km/h. Just as impressive is the vehicle's fuel consumption of 7.6 to 8.1 litres per 100 kilometres � on a full tank, the CLS 320 CDI can travel up to 1,050 kilometres.

C-Class: New six-cylinder engine for the same price as the previous four-cylinder unit

With four new six-cylinder engines, the Mercedes-Benz C-Class now has the most modern engine line-up in its market segment. The diesel engine range is led by the new C 320 CDI, which replaces the five-cylinder in-line engine previously used. The latest in state-of-the-art six-cylinder petrol engine technology will become available in mid-2005 for the first time in three performance classes: in the C 230 (150 kW/204 hp), the C 280 (170 kW/231 hp) and the C 350 (200 kW/272 hp). The models equipped with the new six-cylinder petrol engines consume up to 13 per cent less fuel than their predecessor models.

Mercedes customers will be able to purchase the new and more powerful C 280 for the same price as the C 240 predecessor model. The C 350, which is offered with either the ELEGANCE or AVANTGARDE equipment lines as standard, and is also equipped with 17-inch light alloy wheels, will be available for a lower price than the similarly equipped C 320 predecessor model.

Mercedes-Benz is also offering the C 230 with a V6 engine for the same price as the previous four-cylinder C 230 KOMPRESSOR. Compared to that model, the C 230 delivers additional output of 9 kW/12 hp, something which drivers will notice through the vehicle's greater agility and the enhanced driving pleasure it offers. Despite this, the C 230 displays the typical smooth running and driving comfort of a six-cylinder model. The engine delivers its maximum pulling power of 245 Nm over a broad speed range (2,900 to 5,500 rpm), thus providing the best possible acceleration and rapid sprinting capability. The C 230 goes from zero to 100 km/h in just 8.4 seconds (saloon) and has a top speed of 245 km/h.

The high-torque V6 engine is available in the C-Class saloon, estate and sports coupe models. The C 230 comes with a six-speed manual transmission as standard equipment, but customers can also opt for the seven-speed 7G-TRONIC automatic transmission if they so choose. Additional high-end standard features include the THERMATIC climate control system, NECK-PRO crash-active headrests for the driver and front passenger (in the saloon and estate models), windowbags, seatbelt tensioners and belt-tension limiters in the front and rear, and a multi-functional steering wheel.

The new C-Class model series also includes the C 280 4MATIC and C 350 4MATIC, both of which are equipped with the 4MATIC permanent four-wheel-drive system and provide up to 45 kW/61 hp more power than their predecessor models.

 

Mercedes-Benz CLK-Class


Improved design and technology

For many years now, the letters CLK have been synonymous with fascinating coupe design and open-air cabriolet driving pleasure. The second generation of the CLK-Class has thrilled more than 200,000 motorists worldwide since it was launched in May 2002 as a coupe. A cabriolet version followed a year later. Pronounced stylistic features � such as the uninterrupted line of frameless, fully retractable side windows, the brand-typical louvered radiator grille with its central Mercedes star, the twin-headlamp face and the sweeping lines of the coupe roof � underline the self-confident character of the new CLK-Class and lend it its unmistakable character.

Beginning in early summer 2005, three all-new six-cylinder engines will make the CLK-Class even sportier and more powerful. The new CLK 350 with seven-speed automatic transmission as standard equipment (200 kW/272 hp) will succeed the CLK 320, and offer 25 per cent more output and around 13 per cent higher torque. Another new model is the CLK 280, whose 170 kW/231 hp V6 engine is 36 per cent more powerful than its predecessor, the CLK 240, while torque has been boosted by 25 per cent.

Diesel fans will also find more driving pleasure and dynamic performance in the CLK-Class in future, thanks to the new CLK 320 CDI with state-of-the-art direct diesel injection. The model’s engine output (165 kW/224 hp) and torque (510 Nm with 7G-TRONIC) are extremely impressive, as is the combined fuel efficiency of 7.5 to 7.7 litres per 100 kilometres (coupe; with six-speed transmission: 7.2 to 7.3 l per 100 km). Mercedes-Benz is also offering this state-of-the-art engine in the CLK cabriolet for the first time.

In future, the tried and tested four-cylinder diesel delivering 110 kW/150 hp will be available in the CLK coupe as well. This engine consumes only 6.4 to 6.5 litres of fuel per 100 kilometres. Mercedes-Benz will equip CLK-Class diesel models with particulate filters as standard equipment in Germany, Austria, the Netherlands and Switzerland.

And beginning in June 2005, Mercedes-Benz will be expanding the comprehensive range of standard safety features in all CLK models by introducing the all-new, crash-active NECK-PRO headrest. Other standard CLK safety features will include an automatic tyre pressure loss warning system and ISOFIX child seat mounts. As an option, customers can also purchase bi-xenon headlamps with an active cornering function.

Dynamic look: Redesigned front end and light alloy wheels

The outward appearance of the Mercedes-Benz CLK-Class also expresses the increased power of the extensively upgraded coupe and cabriolet. The redesigned front bumpers with their striking wedge shape and larger air intakes create a more dominant look, as does the modified radiator grille with three instead of the previously four louvers. The vehicle front ends now highlight the character of the two equipment lines as well: For example, the radiator grille louvers are in silver in the ELEGANCE line and black in the AVANTGARDE line.

This differentiation is continued along the sides of the vehicle models: In future, the CLK’s AVANTGARDE equipment line will feature 17-inch five-double-spoke light alloy wheels as standard, while the ELEGANCE line will stand out by virtue of its nine-spoke light alloy wheels (16 inch) in sterling silver. Tyres:

Redesigned brilliant tail lamps with a stronger horizontal division further support the powerful formal language of the CLK-Class. The cover plates in the AVANTGARDE equipment line are also dark-tinted.

Top quality down to the last detail: New colour and material concept for the interior

With their traditional attention to detail, the Mercedes designers have not only upgraded the CLK’s interior but also ensured that the various equipment lines have become even more distinct. The AVANTGARDE line vehicles, for example, are equipped with new black seat coverings as standard, with these consisting of a combination of fabric and ARTICO imitation leather. Alternatively, an all-new leather design is available as an option, whereby the seats, door centre panels and rear side panels feature contrasting colours in combinations of basalt grey, stone beige, tundra brown, flamenco red, and cappuccino brown. Mercedes customers can also choose ash wood trim in the AVANTGARDE line as an option instead of the standard aluminium trim. The interior roof lining in the AVANTGARDE line is black.

Also new is the AVANTGARDE line’s instrument panel, which stands out thanks to a matte aluminium faceplate, white dials with special lettering and chrome rings for the round gauges.

The colour and material design of the ELEGANCE line has also been comprehensively updated, with the interior’s discreet elegance accentuated by a new fabric design in black or basalt grey, new optional leather coverings in black, basalt grey or stone beige, and new decorative wood trim made of ash. In addition, the leather coverings in both equipment lines have been given a new grain that lends them a high-quality and soft character.

Even more dynamism available ex-works: Sports Packages with an extensive range of equipment

Mercedes-Benz is fulfilling the wish of many drivers for even more sporty touches by introducing two new equipment packages that include not only visual features but also technical modifications that provide even better driving dynamics. The Sport Package for CLK-Class coupes and cabriolets, for example, not only includes 18-inch light alloy wheels in multi-spoke design, 225/40 R 18 (front) and 255/35 R 18 (rear) broad tyres, chrome exhaust pipe covers and an exhaust system with a sporty sound for the four and six-cylinder petrol models, but also perforated brake disks, brake callipers adorned with Mercedes lettering, and a sport chassis that has helped to lower the bodyshell by 15 millimetres.

The Sport Package also provides for a sporty upgrade of the interior, with multi-contour front seats for even better occupant lateral stability, steering-wheel shift buttons (for models with automatic transmission), aluminium sport pedals and velour floor mats with a silver lining.

Mercedes customers who opt for the Sport Package AMG will enjoy additional features such as AMG styling with a redesigned front apron, an AMG spoiler edge on the boot cover, chrome AMG dual tailpipes and floor mats embroidered with the AMG logo. The Sport Package AMG also includes 18-inch, five-spoke light alloy wheels painted in sterling silver, with 225/40 R 18 (front), and 255/35 R 18 (rear) tyres.

The Mercedes-Benz CLK 220 CDI:
Powerful acceleration, economical and quiet

The CLK 220 CDI is a new addition to the CLK coupe range. Its modern direct-injection diesel engine has an output of 110 kW/150 hp and exemplary fuel consumption of just 6.4 to 6.5 litres per 100 kilometres (combined consumption). This gives it a range of over 950 kilometres on one tank of fuel.

Like Mercedes-Benz' six-cylinder diesel engines and its new V8 diesel unit, the four-cylinder engine in the CLK 220 CDI is fitted with a VNT (Variable Nozzle Turbine) turbocharger featuring guide blades with electrically variable pitch. This makes the charging process more dynamic and precise, accelerating the generation of boost pressure at low rpm and thereby providing a significant increase in engine power. Seven-hole injection nozzles provide for even finer fuel distribution in the combustion chambers as well as enhanced mixture formation, which has a favourable impact on the engine's exhaust emissions.

The common-rail system operates at a peak pressure of 1,600 bar, which is continuously available, even at low rpm. In order to reduce engine vibrations even further, Mercedes-Benz has fitted the four-cylinder diesel unit with balancer shafts. These rotate in opposite directions to one another and at twice the speed of the crankshaft. In so doing, they compensate for the inherent inertia forces that are generated as the pistons move and which can lead to irritating vibrations. In addition to achieving a substantial reduction in such vibrations, this system also significantly lowers engine noise, both of which result in a considerable increase in driving comfort.

At the same time, twin pilot injection also helps ensure exceptionally smooth running. Just a few milliseconds before actual fuel injection, two small amounts of diesel are injected into the cylinders one after the other. This fuel ignites, thus preheating the combustion chamber, which in turn reduces combustion noise following the principal fuel injection phase.

In Germany, Austria, the Netherlands and Switzerland, the CLK 200 CDI is fitted with a maintenance-free diesel particulate filter as standard.

The Mercedes-Benz CLK 320 CDI:
Cabriolet now also available for the first time with V6 diesel engine

The new CLK 320 CDI cabriolet is the first ever open-top diesel model from Mercedes-Benz.

With an output of 165 kW/224 hp, the new six-cylinder engine � which is also available for the CLK coupe � is one of the most powerful passenger car V6 diesel engines available in this displacement class and also delivers � in combination with the 7G-TRONIC automatic transmission (optional extra) � a highly impressive torque of 510 newtonmetres from engine speeds of as low as 1,600 rpm upwards. This accelerates the coupe model of the CLK 320 CDI from zero to 100 km/h in only 6.9 seconds (cabriolet: 7.2 seconds) and powers it to a maximum speed of 250 km/h (cabriolet: 246 km/h). Equally impressive is a combined fuel consumption of a mere 7.2–7.7 litres per 100 kilometres (cabriolet: 7.8–8.0 l/100 km).

The six-cylinder engine is fitted with common rail direct-injection technology of the third generation. In this system, the injectors, high-pressure pump and electronic valve timing all operate more efficiently, which in turn further reduces fuel consumption, exhaust emissions and combustion noise. In place of the solenoid valves formerly used, the injectors are now fitted with piezoceramics. These exploit an effect discovered in 1880 by the brothers Pierre and Jacques Curie, whereby the application of a voltage to the ceramic material causes it to alter its crystalline structure in a matter of microseconds. As a result, the specially designed valve needles at the tips of the injectors lift with a precision of just a few thousands of a millimetre, thereby ensuring an extremely fine distribution of the fuel injected into the combustion chamber. Furthermore, the piezoelectric valve needles are not only lighter but also have a response time of only 0.1 milliseconds and therefore operate at twice the speed of conventional solenoid valves.

The V6 is aspirated by means of a VNT � Variable Nozzle Turbine � turbocharger, connected up to an intercooler, which reduces the temperature of the compressed and heated air to around 95 °Celsius, with the result that a larger volume of air can be fed into each combustion chamber. In addition, installed downstream from the intercooler is an electrically adjusted butterfly valve, which is used to throttle the V6 engine when the exhaust gas recirculation is active. This valve enables the amount and mixture of the exhaust gas added to the combustion air to be controlled with extreme precision. Before being added to the combustion air, this exhaust gas is also cooled in a heat exchanger.

At the same time, an electrically controlled system in the charge-air manifold progressively reduces the cross-section of the intake port for each cylinder. This alters the swirl of the combustion air, thereby ensuring that the optimum tumble � for both combustion and exhaust emissions � is achieved in each cylinder, at every engine load and speed.

Two oxidising catalytic converters and a large main catalytic converter purify the exhaust gases of the new Mercedes diesel engine, with the result that it also meets the stringent EU 4 limits. Moreover, in Germany, Austria, the Netherlands and Switzerland, the CLK 320 CDI is fitted with a maintenance-free particulate filter system as standard, which reduces particulate emissions even further.

Mercedes-Benz CLK 280


Substantially enhanced performance and torque

The new CLK 280 delivers around 36 per cent more power and 25 per cent more torque than its predecessor, the CLK 240, which translates directly into a substantially improved performance. The CLK 280 coupe accelerates from zero to 100 km/h in only 7.4 seconds (cabriolet: 7.7 seconds) to reach a top speed of 250 km/h � an improvement on its predecessor of 1.8 seconds and 14 km/h respectively. Nevertheless, combined fuel consumption has fallen by as much as 1.4 litres per 100 kilometres, with the new CLK 280 coupe consuming 9.2–9.6 litres per 100 kilometres (cabriolet: 9.5–9.9 l/100 km).

The newly developed V6 engine, which is available for both the coupe and cabriolet models of the CLK class, delivers an output of 170 kW/231 hp and generates a torque of 300 newtonmetres at engine speeds of 2,500 rpm upwards. The engine comes with a six-speed manual transmission as standard; the 7G-TRONIC seven-speed automatic transmission is also available as an optional extra.

When developing the new V6 engine, Mercedes engineers placed an equal priority on each of the following criteria: output, torque, fuel consumption, comfort and exhaust emissions. In so doing, they were able to come up with innovations that have a positive impact across a range of fields rather than merely responding to individual problems.

While the use of 24 valves (four per cylinder) in combination with four overhead camshafts already offers a very solid foundation for the engine's exceptional power, Mercedes engineers went one step further and developed a system that enables the interplay of the 24 valves to be controlled as required � in line with the exact engine load, thereby ensuring an exceptionally fast charge changing process in the cylinders: a stepless, continuously variable camshaft adjustment. Thanks to this new system, the angle of the two intake and the two exhaust camshafts can be continuously adjusted by up to 40 degrees, so that the valves are opened and closed at the most favourable time according to engine load.

Alongside this fourfold, stepless camshaft adjustment, a number of other improvements also contribute to the exemplary performance characteristic of the new V6 engine. These include intake ports designed for optimum flow and throughput, which are fitted with innovative tumble flaps; specially developed valves which, thanks to a shaft diameter of only six millimetres, have only a minimal impact on the flow in the intake ducts; compact combustion chambers to ensure high compression (10.7) and high efficiency; and a newly developed two-step controllable intake manifold.

Mercedes-Benz CLK 350:
The performance of a sports car

With an output of 200 kW/272 hp and 350 newtonmetres of torque, the Mercedes six-cylinder unit in the new CLK 350 is one of the most powerful V6 engines in its displacement class. Maximum torque is available at an engine speed of just 2,400 rpm and remains constant across a wide range up to 5,000 rpm. This provides the powerful acceleration typical of a sports car and enables the rapid sprints required when overtaking. Equipped with the 7G-TRONIC automatic transmission as standard, the 350 CLK coupe accelerates from zero to 100 km/h in 6.4 seconds (cabriolet: 6.7 seconds) and from 60 to 120 km/h in 6.2 seconds (cabriolet: 6.5 seconds).

Variable and continuous adjustment of both the intake and exhaust camshafts reduces fuel consumption under partial load, while ensuring an optimal supply of fresh combustion gas to the combustion chambers at high engine loads. With the help of sophisticated airflow simulations, Mercedes engineers have also configured and optimised all the air intake components. These include an intake module made of magnesium. At the same time, the length of the intake manifold can be varied according to engine speed so as to achieve the best possible torque and output. As a result, the V6 engine already develops around 87 per cent of its maximum torque of 350 newtonmetres at engine speeds of as low as 1,500 rpm.

The intake ports are equipped with tumble flaps that enhance fuel intake and combustion of the fuel-air mixture. These swivel open under partial load, thereby increasing the turbulence of the gas flow into the combustion chambers. At higher engine loads, the tumble flaps are fully recessed in the intake manifold. The use of these innovative flaps reduces fuel consumption by up to 0.2 litres per 100 kilometres depending on engine speed. At the same time, engine smoothness is enhanced. Calculated in line with NEDC methods, the CLK 350 coupe consumes 9.9–10.0 litres of premium grade petrol per 100 kilometres (cabriolet: 10.1–10.2 l/100 km).

In addition, an intelligent heat-management system also contributes to fuel economy. Mercedes engineers have developed a new, electronic map-controlled thermostat which is active in all engine operating situations. This controls heat flow within the V6 engine in such a way that the engine oil and coolant are always at an optimum temperature.

Both the crankcase and cylinder head of the new Mercedes six-cylinder are made of aluminium. The state-of-the-art, lightweight engine also features weight-reduced connecting rods, pistons and balancer weights, all of which contribute to the V6's exceptional smoothness. Between the cylinder walls, a balancer shaft rotates in the opposite direction to the crankshaft and thereby compensates for the inherent vibration moments of the engine. Similarly, the cylinder liners are made of a mixture of aluminium and silicon to reduce friction, distortion and weight.

Mercedes-Benz CLK 500:
Eight cylinders for sporty driving enjoyment

Whether it's a dynamic driving experience with high power output, or comfortable cruising at low engine speeds � the CLK 500's eight-cylinder engine offers both, and more. Depending on the driver's mood, the 5.0-litre engine can deliver a sporty ride or fulfil the passion for pleasurable open-top motoring in the CLK 500 cabriolet.

The V8 engine has a displacement of 4,966 cubic centimetres and a power output of 225 kW/306 hp, thereby lending the CLK 500 the driving dynamics and performance of a thoroughbred sports car. The eight-cylinder coupe accelerates from 0 to 100 km/h in just 5.9 seconds (cabriolet: 6.1 seconds). With the help of its exemplary torque, it can also sprint from 60 to 120 km/h in only 5.1 seconds (cabriolet: 5.5 seconds). Such performance demonstrates the power of the V8 engine and how efficiently this power is utilised by the all-new, seven-speed 7G-TRONIC automatic transmission, which comes as standard equipment in the CLK 500.

An electronically controlled intake module boosts torque at low engine speeds and ensures that the engine always responds instantly to the demands placed on it by the driver � whether on city streets or motorways. More than 400 Nm of torque is made available at an engine speed as low as 2,000 rpm. This corresponds to nearly 90 per cent of the maximum torque of 460 Nm, which the eight-cylinder unit provides from 2,700 rpm and consistently maintains up to an engine speed of 4,250 rpm.

The excellent interaction between the V8 engine and the 7G-TRONIC transmission also produces a positive effect in terms of combined fuel consumption, which totals 10.9–11.4 litres per 100 kilometres (cabriolet: 11.1–11.6 l/100 km). Along with the 7G-TRONIC transmission, the extensive range of standard equipment in the CLK eight-cylinder model includes the THERMOTRONIC climate control system, parameter steering, electrically adjustable front seats with a memory feature, and 17-inch light alloy wheels with 225/45 R 17 (front) and 245/40 R 17 (rear) tyres.

Mercedes-Benz CLK 55 AMG:
Pure dynamism

V8 power, dynamic driving, and high-quality standard equipment � the CLK 55 AMG is the sporty and dynamic top-of-the-line model in the CLK-Class series. The 5.5-litre eight-cylinder AMG engine (270 kW/367 hp) in the coupe and cabriolet ensures that these vehicles live up to their prestigious reputation. The V8 engine, which provides its maximum torque of 510 Nm at 4,000 rpm, displays exemplary power and torque characteristics that guarantee dynamic Mercedes-AMG acceleration: The CLK 55 AMG coupe accelerates from 0 to 100 km/h in just 5.2 seconds (cabriolet: 5.4 seconds) and has a maximum speed of 250 km/h (electronically limited).

Taking its cue from the world of motor racing, the CLK 55 AMG is equipped with aluminium forged pistons, whereby specially developed oil spray nozzles reliably cool the pistons even under the highest engine loads. A newly developed double-flow induction-pressure unit, “assembled� camshafts and a specially tuned variable induction pipe ensure that the cylinders are optimally filled at all engine speeds. They also create the technical basis for the engine’s sporty character.

The AMG sport exhaust system with enlarged pipe cross-sections is equipped with two front wall and four underbody catalytic converters. These work together with a specially constructed muffler system to achieve low exhaust gas pressure. The chrome twin exhaust pipes produce a sonorous V8 sound typical of AMG vehicles. This creates a particularly exciting sensory effect during open-top driving, without generating any annoying sounds. The CLK 55 AMG coupe has a combined fuel consumption of 12.1 litres per 100 kilometres (cabriolet: 12.3 l/100 km).

The five-speed automatic transmission in the CLK 55 AMG � with AMG-SPEEDSHIFT � offers a perfect complement to the dynamic power output development of the AMG eight-cylinder engine. Drivers can select the manual programme "M" to operate the transmission with either a tip-shift device or a push-button console on the steering wheel. Moreover, because the gears are not changed automatically, drivers can ideally exploit the engine's high torque even at maximum engine speed.

A recent model update has given the CLK 55 AMG a redesigned front apron with more prominent wedges and round, chrome-rimmed fog lamps that lend the vehicle an even more aggressive and dynamic character.

Mercedes-Benz E-Class


More versatile and valuable than ever

Never before in its history has the model programme for the Mercedes-Benz E-Class been as versatile, attractive, and dynamic as it is today. The programme now offers 27 engine and body variants to choose from, including 15 saloon versions and 12 estate models. There are also five completely new engines � two CDI six-cylinder units, two V6 petrol engines and, beginning in the autumn of 2005, a V8 diesel that is one of the world's most powerful engines in its class. Mercedes-Benz has also expanded its range of four-wheel drive vehicles in the E-Class series to include the new E 280 4MATIC and the E 350 4MATIC. These will be joined in future by the E 320 CDI 4MATIC, which is powered by a new V6 diesel engine.

The E-Class has been on the market since March 2002 (estate: since March 2003) and is the global and European market leader in its segment.

Among other things, the high-end standard features in the Mercedes-Benz E-Class include an electronic climate control system, a radio/CD stereo system, six-speed standard transmission, light alloy wheels and crash-active NECK-PRO headrests. The E 320 CDI and E 350 � both of which are fitted with six-cylinder engines � come with the 7G-TRONIC seven-speed automatic transmission and parameter steering as well. In addition, Mercedes-Benz has equipped the E 420 CDI and E 500 V8 models with AIRMATIC pneumatic suspension, a four-zone electronic climate control system and the ELEGANCE equipment line.

Mercedes customers can further opt for a new Sport Package to reinforce the dynamic character of the E-Class and personalise their saloon or estate to an even greater extent than before. The Sport Package contains valuable equipment features that are not available individually, including glossy 18-inch light alloy wheels in ten-twin-spoke design, 245/40 R 18 (front) and 265/35 R 18 (rear) broad tyres, silver brake callipers and perforated brake disks, and oval stainless steel exhaust pipe covers. The rear bumper and side skirts come in the sporty design of the AVANTGARDE line.

The interior has been upgraded with features such as a four-spoke sports steering wheel with integrated buttons for operating the automatic transmission, stainless steel pedals with black rubber coverings, front seats with anthracite-coloured leather upholstery, and contrast trim seams in the central area. The Sport Package also includes a sport-tuned chassis, a direct steering system with a speed-based parameter function, and special mufflers that produce a sporty sound.

Mercedes-Benz E 320 CDI:
Perfect combination of driving dynamics and comfort

165 kW/224 hp, 510 Nm maximum torque, and fuel consumption of only 7.3 litres per 100 kilometres � these are the impressive performance figures for the E 320 CDI's new six-cylinder diesel engine, one of the most powerful in its class. The new engine, which replaces the straight five and six-cylinder units previously used, provides up to 38 per cent greater output and torque, thereby ensuring faster acceleration, more powerful sprints, and a higher maximum speed. The E 320 CDI accelerates from 0 to 100 km/h in 6.8 seconds (saloon) and has a maximum speed of 250 km/h (saloon).

The vehicle's maximum torque of 510 Nm is made available at an engine speed as low as 1,600 rpm and is constantly maintained up to 2,800 rpm. Thus the new V6 offers unparalleled torque for its displacement class. What's more, the engine's combination with the standard 7G-TRONIC seven-speed automatic transmission guarantees optimal exploitation of its impressive power output and torque potential in all driving situations.

The materials employed in the vehicle, its design, and its fuel injection and engine control systems are all state-of-the-art. Mercedes-Benz has also developed the world's first aluminium crankcase with grey cast-iron cylinder sleeves for use in a diesel engine of this displacement and performance class. This design made a significant contribution to the six-cylinder engine's low weight of only around 208 kilograms (DIN). As such, the new engine is only slightly heavier than the previous five-cylinder unit. Its weight-to-power ratio, on the other hand, has increased by more than 20 per cent to 0.79 kW/kg � a key factor in the perfect diesel agility the new engine provides.

Fuel injection at 1,600 bar with innovative piezo injectors

Mercedes engineers have made even further advances in fuel economy and exhaust-emission reduction with a third-generation common-rail direct injection system that uses innovative piezo injectors and achieves a higher injection pressure of 1,600 bar.

A high-performance electronic control unit monitors all engine functions � from the quick-start pre-heating unit to the automatic start feature and operation of the high-pressure pump. In addition, the VNT (variable nozzle turbine) supercharger with electrically adjustable guide blades, the exhaust gas recirculation system with control valve, and the air intake throttle are all controlled on the basis of constantly updated vehicle measurement data and in accordance with the situation at hand.

Thanks to this precise engine control system, the V6 unit's nitrogen oxide and particulate emissions are below the strict limits set by the EU 4 guideline. Two oxidation-type catalytic converters handle the conversion of carbon monoxide and hydrocarbons. In order to further reduce particulate emissions, Mercedes-Benz is fitting the new E 320 CDI with particulate filters as standard equipment in Germany, Austria, the Netherlands and Switzerland.

Mercedes-Benz E 320 CDI 4MATIC:
First Mercedes-Benz diesel passenger car with permanent four-wheel drive

For the first time, Mercedes-Benz is offering a diesel passenger car with permanent four-wheel drive � the new E 320 CDI 4MATIC. The powerful, high-torque six-cylinder is a perfect match for the 4MATIC and also ensures a top performance in the saloon and the estate. The E 320 CDI 4MATIC accelerates from zero to 100 km/h in only 7.4 seconds (saloon) and has a top speed of 244 km/h (saloon).

Thanks to the third generation of common-rail direct injection, the newly developed six-cylinder diesel engine is an outstanding performer in terms of its improved fuel economy and even lower exhaust gas emissions � and drivers will be able to hear that the engine runs more smoothly. Even at 1,600 rpm, the V6 engine delivers a maximum torque of 510 Nm, the highest value in its displacement class. The six-cylinder’s torque remains constant up to 2,800 rpm. Also exemplary is the E 320 CDI 4MATIC’s fuel consumption: 7.9 to 8.1 litres per 100 kilometres (the saloon’s combined consumption).

In combination with the ESP® electronic stability program and the 4ETS electronic traction system, the permanent four-wheel drive system works to assist drivers in coping safely and confidently with critical situations. The E-Class 4MATIC models deliver greater traction and a more dynamic performance under adverse weather conditions such as ice and snow, on wet roads, and also when drivers are starting, accelerating and cruising on poor road surfaces.

At the same time, 4ETS ensures typical Mercedes standards of driving comfort. This is because the system operates without conventional differential locks, which can detract from the comfort and handling of other four-wheel-drive cars. With 4ETS, the spinning wheels are braked in a targeted manner and the drive torque is transferred to the wheels with good traction. This is how the electronic traction control system achieves the same effect as three differential locks. A single-step transfer case transfers the engine’s torque to the front and rear axles in a 40:60 ratio.

Mercedes-Benz E 420 CDI:
Powerful performer with 231 kW/314 hp

Beginning in autumn of this year, Mercedes-Benz will be putting one of the world’s most powerful diesel engines for passenger cars into series production of the E-Class. In contrast to its predecessor eight-cylinder diesel, this engine offers 20 per cent higher output and 30 per cent more torque. The figures: 231 kW/314 hp, and 730 Nm of torque at 2,200 rpm.

With its robust torque, the E 420 CDI accelerates from a standstill to 100 km/h in only 6.1 seconds and can sprint from 60 to 120 km/h in third gear in just 5.4 seconds. The combined fuel consumption is 9.3 litres per 100 kilometres.

In addition to an aluminium crankcase, cooled exhaust gas recirculation and electronic intake-air throttle, the third-generation common-rail direct injection is an impressive technological highlight of the new Mercedes eight-cylinder. By using piezo injectors, the fuel injection can be more quickly and precisely adjusted to individual load and torque conditions than was possible with the solenoid valves previously used. That has a positive effect on emissions and fuel consumption and contributes to a quieter engine.

The Mercedes engineers focused especially intensively on the airflow upstream and downstream of the turbochargers. Using computational fluid dynamics and simulations, they succeeded in reducing the inherent pressure losses in the charge-air lines, thus achieving a long-term improvement in the engine’s air supply. Compared to the predecessor CDI eight-cylinder from Mercedes-Benz, the pressure loss in the charge-air lines was reduced by up to 60 per cent. That means an increase of up to 15 per cent in the air mass that can flow into the engine. The V8 uses this air to generate power and torque. And the improved charge-air cooling enhances this effect: The new CDI eight-cylinder’s air/water intercooler is integrated with two water coolers into a special low-temperature circuit, where the charge air is cooled by up to 120 degrees Celsius. This increases the air density at full load by up to 25 per cent.

Thanks to specially designed hollow areas in the intake lines, the air volume upstream from the turbochargers is increased, and torque is boosted by about 15 per cent in the lower engine speed range.

The new Mercedes-Benz eight-cylinder diesel comes with two oxidising catalytic converters and a maintenance-free particulate filter as standard, which ensures reliable compliance with the stringent EU4 exhaust emission limits. The particulate filter works without additives and is regenerated while the vehicle is running by means of adjustments to specific engine functions as needed, for example by doubling secondary fuel injection.

A seven-speed automatic transmission and AIRMATIC suspension are also standard equipment in the new top diesel model from Mercedes-Benz.

Mercedes-Benz E 280:
A six-cylinder for discerning customers

No other engine in this displacement class can match this new six-cylinder petrol engine in terms of its output and torque characteristics, which have been specifically designed for dynamic performance and enjoyment. Mercedes-Benz is offering the engine in two output levels for the E-Class: in the E 350 and the new E 280.

From 2,996 cm3 of displacement, the E 280’s engine generates 170 kW/231 hp and delivers a maximum torque of 300 Nm from 2,400 rpm. Drivers can take advantage of this torque at a wide range of engine speeds up to 5,000 rpm. The E 280 sprints from zero to 100 km/h in 7.3 seconds and has a maximum speed of 250 km/h (saloon). The combined fuel consumption is 9.3 to 9.5 litres per 100 kilometres.

The aluminium V6 engine excels with a unique package of technical features. For the first time in a V6 engine it has variable intake and exhaust camshaft adjustment, which increases the output and torque while contributing to fuel economy.

The length of the intake manifold can be varied according to the engine speed to achieve the best possible torque and output.

The intake module is equipped with flaps that open or close depending on engine load and speed: At low engine speeds, the flaps are closed, which causes pressure waves to form in the long intake manifolds. These waves support the intake process and improve torque optimisation.

The inlet ports are equipped with so-called tumble flaps that improve the intake process and the combustion of the fuel-air mixture.

These flaps are electro-pneumatically operated. They swivel open under partial loads in order to increase the flow turbulence in the combustion chambers. This leads to a substantial reduction in fuel consumption and also ensures that the engine runs quietly. The tumble flaps are controlled and operated in accordance with the driving situation on the basis of the stored characteristics.

The E 280 comes with a six-speed manual transmission as standard. The seven-speed 7G-TRONIC automatic transmission, which is available as an option, works very well in tandem with the V6 engine and also provides for more powerful acceleration, faster sprints, and lower fuel consumption.

Mercedes-Benz CLS-Class


Now even more attractive with a new six-cylinder CDI engine

The new Mercedes-Benz CLS-Class has been thrilling motorists around the world since October 2004. The four-door coupe is based on a unique vehicle concept that combines for the first time the elegance and dynamics of a coupe with the comfort and functionality of a saloon. Although the vehicle's spaciousness, boot volume, and suitability for everyday use are all equal to that of a saloon, its lines display the fascinating emotional character of a true coupe. This unique combination puts the CLS-Class a coupe-generation ahead of its rivals.

The engine programme for the model series includes two powerful petrol units that deliver 200 kW/ 272 hp and 225 kW/306 hp, respectively, as well as an all-new V6 diesel with an output of 165 kW/224 hp. All of the engines work in tandem with the 7G-TRONIC seven-speed automatic transmission, which comes as standard equipment.

Through its unique synthesis of coupe and saloon elements, the new CLS-Class offers clear value added as compared to other coupes. As such, Mercedes-Benz is underscoring its role as a trendsetter for novel vehicle concepts. With its attractive and fascinating coupe design, exclusive equipment features, and pioneering technology, the CLS-Class is designed especially to appeal to those motorists for whom driving is a passion.

The four-door coupe concept ensures easy entering and exiting for rear passengers, who are provided with two comfortable individual seats and enjoy a high amount of roominess and freedom of movement. The distance between the front and rear seats is 829 millimetres. The coupe thus offers more space in this regard � and in terms of shoulder and elbow room (1,422 and 1,464 millimetres in the rear, respectively) � than do comparable saloons. The driver and front passenger can enjoy newly developed, electrically adjustable seats as standard; an active ventilation system or dynamic multi-contour seats are also available as options.

The boot holds up to 505 litres of cargo (VDA measurement method), thus exceeding the volume of other coupes, and even some saloons.

Standard: Seven-speed automatic transmission, radio, and air conditioning

Standard equipment in the CLS 320 CDI and CLS 350 � both powered by a six-cylinder engine � include the THERMATIC climate control system, a stereo radio, a parameter steering system, a leather-covered steering wheel, 17-inch light alloy wheels, and 245/45 R 17 broad tyres. The CLS 500 top-of-the-line model offers the comfort of the S-Class segment with the help of features that include the AIRMATIC suspension system and the THERMOTRONIC four-zone climate control system; 18-inch light alloy wheels with 245/40 R 18 broad tyres also come with the standard equipment package.

The CLS-Class is equipped with state-of-the-art safety features offering the highest level of occupant protection. Such features include adaptive front airbags, windowbags and sidebags, seatbelt tensioners and belt-tension limiters at all seats, and crash-active NECK-PRO headrests for the driver and front passenger. A range of further innovations that make driving even safer is also optionally available for the four-door coupe. These include, for example, powerful bi-xenon headlamps with an active cornering function; Mercedes-Benz can also combine these with cornering lights. Additional optional Mercedes innovations for even greater driving comfort and enjoyment in the CLS-Class are the DISTRONIC proximity cruise control system, LINGUATRONIC voice command, the COMAND APS operation and display system with Europe-wide DVD navigation, and the KEYLESS-GO entry and driver authorisation system.

The Mercedes-Benz CLS 320 CDI:
Diesel power in its most attractive coupe form

In combination with the new V6 diesel engine from Mercedes-Benz, the four-door CLS coupe delivers a driving experience of a special kind. In fact, this powerful yet smooth-running CDI engine � which boasts among the highest performance and torque of its displacement class � takes the concept of dynamic diesel power to a new level. With an output of 165 kW/224 hp and a maximum torque of 510 Nm � which is available at engine speeds of as low as 1,600 rpm and remains constant all the way up to 2,800 rpm � this V6 delivers immense acceleration and superb elasticity. Thus equipped, the new CLS 320 CDI races from zero to 100 km/h in 7.0 seconds and is capable of a maximum speed of 246 km/h. Equally impressive is a fuel consumption of a thrifty 7.6 to 8.1 litres per 100 kilometres, which provides a range of up to 1,050 kilometres on one full tank of 80 litres.

Thanks to the latest fuel-injection technology and high-precision combustion control, the new V6 is able to meet the stringent EU 4 limits without the need for a particulate filter. Nonetheless, in Germany, Austria, the Netherlands and Switzerland, the CLS 320 CDI will also be fitted with a particulate filter as standard, which reduces particulate emissions even further.

The design of the new engine, the materials and the fuel-injection technology all correspond to the very latest standards. In what is a world first for a diesel engine of this displacement and power class, Mercedes-Benz has developed an aluminium crankcase with grey cast iron cylinder liners, which has led to a significant weight reduction. Overall, the V6 weighs in at around just 208 kilograms (DIN). This increases the power-weight ratio by over 20 per cent to 0.79 kW/kg � a major factor in generating the supreme agility offered by this new diesel engine.

Further enhancements to the common-rail direct injection technology, which has now entered its third generation, have yielded even more advances in the areas of fuel consumption, exhaust emissions and combustion noise. Similarly, the newly developed piezo injectors operate much more quickly and precisely than the solenoid valves formerly used, thereby ensuring extremely accurate control of the amount of fuel supplied to the cylinders. As a result, fuel injection is even more precisely adjusted to engine speeds and loads, so that five fuel injections per power stroke � at a peak pressure of up to 1,600 bars � are now possible.

At the same time, an electrically controlled system in the intake ducts modifies the swirl of the air flowing into each cylinder, thereby enhancing the combustion process and producing a further reduction in fuel consumption and exhaust emissions.

Further technological highlights of the V6 CDI engine include a Variable Nozzle Turbine (VNT) turbocharger featuring guide blades with electrically variable pitch, an exhaust gas recirculation system complete with control valve, and an intake-air control system. When fitted in the CLS-Class, the new engine comes with the seven-speed 7G-TRONIC automatic transmission as standard.

Mercedes-Benz C-Class


The most advanced engine line-up in the market segment

 

In the period since May 2000, the Mercedes-Benz C-Class has won over more than 1.6 million drivers worldwide with its successful mix of modern technology, sporty agility and exceptional comfort for long-distance driving. Never before has Mercedes-Benz sold so many vehicles of one series in such a short space of time.

The C-Class range covers not only the sporty yet elegant saloon but also the highly versatile estate and the youthful, dynamic sports coupe, both of which were launched in March 2001. As of summer 2005, the saloon and estate models from this highly successful series will be available with a choice of nine different engine options (sports coupe: six), with outputs ranging from 90kW/122 hp to 270 kW/367 hp. Four of these engines are new additions:

Two further additions are the C 280 4MATIC and the C 350 4MATIC. Both feature the 4MATIC permanent all-wheel drive and offer up to 45 kW/61 hp more power in comparison to predecessor models.

The V6 models are also optionally available in combination with the unique seven-speed 7G-TRONIC automatic transmission, which further enhances the power and elasticity of these new engines. The 4MATIC models are fitted as standard with a five-speed automatic transmission.

NECK-PRO headrests and air conditioning fitted as standard

The extensive range of standard equipment on offer with the C-Class includes automatic air conditioning, a multi-functional steering wheel, windowbags, active-safety NECK-PRO headrests for the driver and front passenger (in saloon and estate models), and enhanced scratch-resistant paint on the basis of nanotechnology. In addition to the individual CLASSIC, ELEGANCE and AVANTGARDE equipment lines, Mercedes-Benz also offers, as optional extras, two sport packages that further accentuate the dynamic image of the C-Class.

Further information on the precision, attention to detail and dynamism of the Mercedes-Benz C-Class can be found in the separate press folders for News and Reports.

The Mercedes-Benz C 230:
An attractive introduction to six-cylinder performance

The C 230 features a newly developed V6 engine boasting a performance and torque characteristics based on a unique combination of high-tech engineering. This includes variable adjustment of both the intake and exhaust camshafts, thereby ensuring that the 24 valves are opened and closed at the most favourable time according to engine load. In turn, this substantially enhances the charge cycle in the cylinders and reduces energy losses as well as contributing to improved fuel economy when the engine is operating at partial loads.

In addition, the intake ducts are equipped with tumble flaps that enhance fuel intake and combustion of the fuel-air mixture. These swivel open under partial load, thereby increasing the turbulence of the gas flow into the combustion chambers. At higher engine loads the tumble flaps are fully recessed in the intake manifold. Use of this technology reduces fuel consumption as well as enhancing engine smoothness. Calculated in line with NEDC methods, the new C 230 consumes 9.3–9.6 litres of premium petrol per 100 kilometres (combined consumption; saloon model).

With an output of 150 kW/204 hp, the V6 engine also displays exemplary torque characteristics, delivering a peak of 245 newtonmetres across a broad rpm range (2,900–5,500) and thereby providing powerful acceleration and rapid sprints. From a standing start, the C 230 accelerates to 100 km/h in just 8.4 seconds (saloon model) and reaches a top speed of 245 km/h.

Thanks to variable camshaft adjustment, tumble flaps in the intake ducts, internal exhaust gas recirculation, secondary air injection and other features, the exhaust emissions of the new C 230 already remain at a very low level during the combustion process. In addition, a powerful exhaust emission control system featuring two catalytic converters placed close to the engine reduces the exhaust emissions below the EU 4 limits.

This powerful new V6 engine is available with the saloon, estate and sports coupe models of the C-class. The C 230 is fitted as standard with a six-speed manual transmission; the seven-speed 7G-TRONIC automatic transmission is also available as an optional extra. Further highlights in the extensive and high-grade range of standard equipment include the THERMATIC air-conditioning system, the active-safety NECK-PRO headrests for driver and front passenger (in saloon and estate models), window airbags, seat-belt tensioners and seat-belt tension limiters (front and rear), and a multifunctional steering wheel.
