The World's First Premium Sports Activity Vehicle in its Class

BMW is enlarging the highly successful X-family through the addition of a very dynamic and versatile new vehicle: The new BMW X3 combines the outstanding agility of a typical BMW with the broad range of practical benefits offered by a Sports Activity Vehicle (SAV). The BMW X3 is indeed the first premium vehicle of its kind in the SAV segment below the X5, setting out in the market to conquer roads and tracks the world over. The X3 combines the characteristic proportions of a Sports Activity with both classic and new BMW design elements. The modern design language with that unique interplay of concave and convex surfaces gives the X3 a youthful, fresh appearance. Numerous characteristic details, particularly the re-interpretation of the classic "Hofmeister kick" in the rear side windows, the newly designed double kidney grille, as well as the front and rear lights underline the unique position of this special model within the BMW range. Long wheelbase with short overhangs and the roof line slowly dropping to the rear accentuate the dynamic character of this Sports Activity even at a standstill. Powerfully bulged wheel arches and the striking front end, finally, give this newcomer a strong character full of self-confidence, emphasizing its superior stance in every situation. A new dimension in the BMW model range
The basic facts and figures alone clearly show that this is an all-new, absolutely unique model series: Measuring 4,565 millimetres (197.7´´) in length, the X3 is 87 millimetres (3.4´´) longer than the 3 Series Touring, but almost 30 centimetres (11.8´´) shorter than the new 5 Series Saloon. And measuring 4,667 mm (183.7´´) from bumper to bumper, the X5, in turn, is clearly the X3's bigger brother. We find the same relative figures when considering the wheelbase of the X3 measuring 2,795 millimetres (110.0´´), versus 2,725 millimetres (107.3´´) on the 3 Series Touring and 2,820 millimetres (111.0´´) on the X5. In terms of height, on the other hand, the X3, measuring 1,674 millimetres (65.9´´), is clearly higher than both the 3 Series Touring (1429 mm/ 56.3´´ ) and the 5 Series Saloon (1,468 mm/57.8´´ ), only the X5 leaving an even longer shadow with its height of 1,715 mm (67.5´´). And with only the driver sitting at the wheel, ground clearance of the X3 measuring exactly 201 millimetres (7.91´´) is absolutely sufficient even on rough terrain. Muscular straight-six power units for sporting performance
BMW's straight-six gasoline and diesel engines famous for their supreme refinement and performance ensure dynamic motoring wherever you go. Developing maximum output of 170 kW (231 bhp), the agile X3 3.0i reaches a top speed in standard trim of 210 km/h (130 mph), the optional high-speed set-up available with the Sports Package allowing an even higher top speed of 224 km/h (139 mph). The power unit featured in the X3 2.5i, in turn, develops maximum output of 141 kW (192 bhp). Revving smoothly even up to high speeds, the 3.0-litre six-cylinder also allows the driver to accelerate quickly and dynamically from 0-100 km/h in just 7.8 seconds. And despite this performance the ultra-modern 3.0-litre gasoline engine outperforming even the strict EU 4 emission standard consumes just 11.4 litres (100 kilometres), equal to 24.8 mpg Imp. The aficionado of supreme torque will be thrilled in particular by the X3 3.0d, the straight-six turbodiesel with second-generation common rail direct fuel injection only recently upgraded developing maximum output of 150 kW (204 bhp) in the X3, and giving this superior Sports Activity no less than 410 Nm (302 lb-ft) maximum torque. This also provides a top speed of 210 km/h (130 mph) increased even further to 218 km/h (135 mph) with BMW's high-speed set-up. And when it comes to acceleration, the diesel is also an outstanding performer, booming from 0-100 km/h in just 7.9 seconds. Fuel consumption in the process remains very modest, however, the X3 3.0d requiring just 8.4 litres of diesel for 100 kilometres, equal to 33.6 mpg Imp. All three engine variants come as standard with a six-speed manual gearbox and are available as an option with five-speed automatic transmission. The new xDrive all-wheel-drive system
The all-new, intelligent xDrive all-wheel-drive system setting a new standard in the agility of all-wheel-drive vehicles is a particular highlight of the BMW X3: xDrive allows infinite, fully variable distribution of drive forces between the front and rear axle, the system immediately recognising the need for a change in power distribution and responding extremely quickly to such a change, in usual road-going situations generally before the wheel even loses its grip. This enables xDrive to transmit optimum drive power to the respective axle at all times even when taking a bend at speed, significantly reducing over- and understeer in the process. On the road xDrive offers a significant improvement of agility, driving pleasure and safety all in one. Suspension control systems such as DSC are not required until a much later point in time than on a conventional all-wheel-drive vehicle, and xDrive guarantees better traction and driving conditions on rough or slippery terrain, since engine power is transferred almost instantaneously to the wheels with more grip as soon as a wheel is about to spin, thus reliably interrupting the flow of traction. Excellent driving experience thanks to the commanding seating position
In its versatility the new X3 is an outstanding performer not only on all kinds of terrain, where it consistently demonstrates its agile and dynamic character. Rather, the sophisticated interior and the wide range of equipment make the X3 the ideal BMW for the active and versatile individualist in every other respect, too. Sitting in their commanding position so characteristic of a BMW Sports Activity, the occupants not only see the world around them from a very clear, pleasant perspective, but also enjoy a very modern and spacious interior: The X3 combines elegance and an aesthetic look appropriate for a vehicle of this character with a sporting ambience and a wide range of practical details. Able to choose from a great many classical as well as sporting and modern materials and colours, the customer has numerous options in personalising the interior of his - or her - X3. Within the cockpit the two circular instruments are grouped in typical BMW style within an elegant pinnacle, the middle of the dashboard is dominated by the optional 16:9 colour monitor of the navigation system moving up automatically when in use. Lots of space and superior functions
The X3 offers truly ample space behind the tailgate opening up to a steep angle for easy access, allowing convenient accommodation of all kinds of luggage and sports equipment such as several mountain bikes: Depending on the arrangement of the seats, luggage space is up to 1,560 litres or almost 55 cubic feet. Numerous additional storage compartments and boxes round off the superior functionality of the X3 with a service load, depending on the engine, of up to 500 kilos (1,100 lb). Unladen weight is between 1,740 kg/3,837 lb (X3 2.5i) and 1,850 kg/4,079 lb (X3 3.0d). And if you wish to take along even heavier and bulkier sports equipment or any other kind of trailer, the optional towing hook on the X3 2.5 is homologated for trailers weighing up to 1,800 kg (3,969 lb), the two three-litre models even being able to tow 2,000 kg (4,410 lb) on a trailer equipped with brakes. Regardless of the weight towed, BMW's unique trailer stability control ensures safe driving conditions with, say, a boat trailer or other trailers of any kind. This extension of the DSC suspension control system is standard, just like HDC Hill Descent Control for taking downhill gradients safely even on loose ground. In the process of developing the X3, BMW's engineers have naturally given particular significance to active and passive safety. Right from the start, the remarkable configuration and design principle of a BMW Sports Activity, with the front drive shaft running through the oil sump, has given the X3 a very low centre of gravity, reducing body sway in the process. With its intelligent distribution of power, xDrive keeps the X3 very stable and secure even in fast bends, generally avoiding critical situations from the beginning. And should such a situation arise nevertheless, DSC suspension control featured as standard intervenes immediately to restore the stability of the X3. Yet a further feature fitted as standard on the X3 is the Tyre Pressure Indicator (TPI) constantly comparing wheel speed in order to monitor air pressure in the tyres and giving the driver both an optical and an acoustic warning in the event of any loss of pressure. Designed and developed as a Sports Activity, the X3 has superior features and abilities clearly defined from the start: While the road is the preferred terrain of this outstanding vehicle, it also offers safe and far-reaching driving qualities on rough terrain ensured, first, by xDrive, BMW's new all-wheel-drive system and, second, by superior ground clearance of 201 millimetres (7.91´´), together with an embankment angle of 26.1º at the front and 23.6º at the rear, as well as a ramp angle of 19º providing the freedom required on all kinds of surfaces. The ramp angle, incidentally, is the maximum admissible angle of a ramp such as a driveway leading into an underground garage without the vehicle touching the ground between its axles as it proceeds up or down such a gradient. Two further criteria which would also look good even on an all-out offroader are the ability to cross bodies of water up to 50 centimetres or almost 20´´ deep and the maximum climbing gradient when setting off of 33 per cent. Aerodynamic objectives: superior driving pleasure, low fuel consumption. The new BMW X3 not only looks very good in its styling and design, but also offers superior aerodynamics: Careful calculations in the early development phase and thorough optimisation in the wind tunnel, first using 1:2.5 models and then models in original size, have given the X3 an airflow concept with a drag coefficient Cd of 0.35 on all six-cylinder models, whether petrol- or diesel-engined. A drag coefficient as low as this is quite unique within the market segment the new BMW X3 is now entering, a low Cd rating offering the driver supreme performance on very little fuel, particularly at high speeds. Cooperating closely on all relevant details, BMW's aerodynamicists and designers working in the wind tunnel have succeeded, inter alia, in giving the X3 a perfectly streamlined rear spoiler. The reduction of internal resistance in the cooling air ducts, in turn, improves both the supply of cooling air and the flow of air out of the vehicle. Airflow to the front axle and manual gearbox have likewise been optimised, BMW's engineers also keeping the underfloor of the X3 very smooth and flat for an optimum flow of air. Aerodynamic refinement of the BMW X3 provides optimum qualities also in terms of driving dynamics, very low lift forces front and rear for a vehicle of this kind serving to press the X3 on to the road particularly at high speeds both when driving in a straight line and in bends. This, in turn, enhances the X3's sporting and agile performance, lift forces reduced to a minimum also helping to maximise active driving safety through longitudinal stability and driving manoeuvres highly relevant to safety such as a quick lane change, etc. Additional highlights: panorama roof and Adaptive Headlights
The BMW X3 comes with a very wide range of optional features, two particular highlights being the new, large panorama roof and BMW's innovative ALC Adaptive Headlights. The two-piece panorama roof extends almost completely throughout the entire roof area of the X3, covering a glass area of 0.65 square metres. And the driver is able to open up the roof completely simply at the touch of a button. Adaptive Headlights, in turn, improve the driver's visibility in the dark by swivelling to the side in an infinite adjustment process geared to the steering angle of the vehicle. This adjusts the two bi-xenon headlight units as required as a function of the steering angle, yaw rate and road speed, thus illuminating bends ahead of the driver clearly and brightly. BMW offers the particularly performance-minded purchaser of the X3 a special Sports Package which, thanks to its specific suspension set-up, gives the X3 an even higher top speed. Further features included in this package are white direction indicators, satin chrome, and star-spoke light-alloy wheels, as well as a leather sports steering wheel and sports seats for both the driver and front passenger. The new BMW X3 will be available in Europe and North America from the beginning of 2004. Other markets will follow later.

Design

The X3 comes with those unmistakable proportions so typical of BMW: A long and striking engine compartment merging smoothly into the coupé-like passenger cell or “greenhouse� positioned relatively far to the rear, with comparatively steep A-pillars forming a soft but dynamic sweeping motion in connecting the two elements. Short overhangs and a long wheelbase, in turn, give the X3 a clear look of dynamic performance and stability. Powerfully arched wheel housings ensure a sporting look full of muscular flair, high ground clearance and black body trim proving that this is a robust, sturdy vehicle quite fit for rough use beyond the beaten track. But at the same time the elegant design of the body leaves no doubts about the premium qualities of the X3 in even the most sophisticated, high-class environment. Apart from the proportions of the X3, particularly the exciting surfaces create a powerful, dynamic effect, clear geometric lines mingling with tense surfaces and striking transitions to create a touch of three-dimensionality. The concave and convex areas, together with the subtle flow of light and shadow, exude a touch of power, dynamism and, at the same time, light agility so appropriate to such a vehicle. Characteristic front end – striking lines
Particularly the front end of the X3 shows that this not “just� a typical BMW, but also a member of the X-family, the dual headlights and kidney grille bearing clear testimony to the brand’s identity. The powerful bumper, in turn, accentuates the robust character of an SAV also borne out by all the details, such as black rods in the kidney grille in their wide, square and muscular design. Other features again characteristic of the X3 are the light units extending into the engine compartment lid almost at right angles, with the direction indicators wrapped around the side. The shoulder line at the side extends out of the direction indicators, continuing above the engine compartment lid all the way to the rear. The shoulder line and the light dividing edge are indeed the two most striking elements at the side of the vehicle, running parallel to one another to create a clear, geometric impression. At the same time these lines interact with the tense convex and concave surfaces, ensuring subtle interplay of light and shade in the surfaces of the body for a supreme touch of sporting style and agile appeal. Precise lines and characteristic steps give the rear end of the X3 a three-dimensional look full of unmistakable character. Convex/concave transitions in the individual surfaces and areas give the vehicle depth and style, the striking roof spoiler serving not only an aerodynamic purpose, but also giving the rear end a powerful and muscular touch. Through their form and graphic design, in turn, the rear lights provide a new interpretation of the L-shaped configuration so typical of BMW, showing their resemblance to the X5 and once again taking up the lines of the X3 in their coloured surfaces. Interior reflecting the X3’s dynamic character
The striking, powerful sculpture of the exterior continues throughout the interior of the car. Firm, dynamic surfaces intentionally subdivided by steps and edges express versatility, sportiness and agility. Modern materials, sophisticated surface grains and tastefully accentuated areas underline both the elegant and the sporting character of the X3. The dashboard is clearly oriented along horizontal lines, emphasizing the feeling of supremacy provided from the start by the commanding seating position in the X3. This is then supplemented by the discreet driver orientation of the centre console, placing the focus on the man – or woman – at the wheel. Strong, robust door handles allude to the sturdy character of this SAV, intersecting with the armrests and extending down to the lower edge of the doors. The qualities of the X3 as a genuine driving machine are further emphasized by additional door pockets with nets and large storage boxes in the centre console. In its concept of materials and colours, the X3 combines two features in one: sportiness and elegance. This means both modern, sporting materials such as aluminium and more luxurious materials such as full leather upholstery and wood trim. Special materials of the highest quality are used throughout the car, at the same time leaving ample room for individual style. “Network� describes a high-quality upholstery finish available in three colour variants. The leatherette finish is called “Sensatec� and comes in two colours, “Ambiente� is the name of the leather upholstery available in a range of no less than five colours. Light-reflecting piping round the edges is a particular feature, splitting the seats and backrests down the middle and accentuating the lines of the seats.

Chassis and Suspension

Through its basic configuration alone, the X3 bears a clear resemblance to the X5 and, accordingly, to BMW’s various saloons: The starting point is the unitary body structure and the chassis with four individual wheels running on independent suspension. In its basic concept, the chassis of the X3 incorporates two axle configurations which have proven their qualities thousands of times: The front axle is an all-new, weight-optimised axle concept with a double-joint spring strut axle made of steel and incorporating the anti-roll bar and gas pressure dampers, adjusted in its kinematic behaviour to the specific features and requirements of the X3. The rear central-arm axle with twin-sleeve gas-pressure dampers and an anti-roll bar stand out in particular through its comfort-building dual-elastic final drive mount, with kinematic behaviour again being modified to suit the higher centre of gravity of this Sports Activity Vehicle. Servotronic and sports suspension as an option.
The X3 is kept reliably on course by rack-and-pinion steering with precisely the right BMW set-up to provide a sporting and direct feeling at all times. Servotronic with speed-related power assistance is available as an extra, offering a particularly high standard of power assistance at low speeds, on bad surfaces, when manoeuvring, or when parking. As an option the X3 is also available with sports suspension maintaining the same high level of ground clearance while offering firmer springs, dampers and anti-roll bars. As part of the Sports Package, the optional high-speed suspension set-up is available for both the X3 3.0i and 3.0d. In this case the all-season tyres fitted as standard are replaced by V- or summer tyres running on 18-inch rims and conceived also for higher speeds. Top speed in this case is up to 224 km/h (139 mph) on the X3 3.0i and 218 km/h (135 mph) on the X3 3.0d. BMW’s compact SAV comes as standard on 17-inch aluminium rims with 235 all-season tyres. Optional 18-inch wheels in various design concepts and for various sizes of tyres are also available. The BMW X3 is fitted as standard with a TPI Tyre Pressure Indicator recognising any loss of pressure in the tyres while driving and sending an appropriate warning signal to the driver. To ensure ongoing mobility in the event of a puncture, finally, the X3 features an emergency wheel just to be on the safe side.

The New xDrive All-Wheel-Drive System

“xDrive� is the – appropriate – name of the new, intelligent all-wheel-drive concept with active dynamic driving control now featured by BMW. This sophisticated technology not only provides optimum traction under difficult conditions, but also, through its electronically controlled variable distribution of power front-to-rear, ensures greater driving safety and enhanced dynamic performance on the road. Featuring as a Sports Activity Vehicle (SAV), the BMW X3 has been developed above all for excellent driving characteristics on the road. It therefore goes without saying that the widely lauded driving characteristics of all BMW cars set the benchmark for the X3 in its process of development, the new xDrive all-wheel-drive system being able to split up drive power very quickly and fully variably between the front and rear axle, depending on driving conditions. Proactive power distribution also ensures maximum all-wheel-drive performance before any of the wheels are able to spin on the road, the electronically controlled multiple-plate clutch with an extremely quick response time transmitting the power of the engine via a chain-driven drive shaft running parallel to the engine at the left all the way to the front axle. Like on the X5, the drive shaft is linked to the right front wheel by a connection shaft running through the oil sump, an intelligent concept serving, inter alia, to lower the position of the engine and, accordingly, the X3’s centre of gravity, while maintaining a good level of ground clearance at the same time. This benefits above all the X3’s driving dynamics, reducing body sway in bends and providing good driving characteristics even on the worst and toughest surfaces. The “heart� of BMW’s xDrive technology: an electronically controlled multiple-plate clutch.
The “heart� of BMW xDrive technology is fitted in the power divider: the electronically controlled multiple-plate clutch masterminding the flow of power to the front axle within milliseconds, depending of course on current requirements. In an extreme case the front and rear axles may indeed be either completely disconnected or connected rigidly to one another, the longitudinal lock then serving as a rigid link, as with conventional all-wheel drive. The transverse lock, that is the flow of power to the two front and rear wheels, is provided by DSC using the electronic brake function: Whenever a wheel threatens to spin without conveying power, it is slowed down by the brakes, the differential in the final drive automatically feeding more power to the wheel at the other end of the axle. The big advantage of xDrive: rapid information allowing a quick response.
The new xDrive all-wheel-drive system serves as the “brain� controlling the flow of power to the wheels. Directly networked to the DSC driving stability system, xDrive enables DSC to operate even more efficiently. And indeed, this is a mutual partnership in a win-win situation, DSC also giving xDrive a number of benefits. Contrary to other all-wheel-drive systems, for example, xDrive is proactive: While conventional all-wheel drive does not respond until the wheels have started to spin, xDrive, evaluating the driver’s wishes by means of, say, the position of the gas pedal, is able to recognise driving situations in which all-wheel drive is beneficial. The result is all-wheel-drive performance and stability before the wheels are able to build up any slipping action in the first place. xDrive also uses all the information gathered by DSC Dynamic Stability Control, the yaw rate sensor, for example, determining any rotating movement of the vehicle and the steering angle sensor registering the position of the steering wheel. Together with information on the speed of the vehicle provided by the wheel sensors as a function of lateral acceleration, and on the basis of engine data, xDrive is able to determine the specific driving situation at an earlier point in time, distributing drive power perfectly between the front and rear axles. The result is a significant improvement of agility the driver will appreciate above all on winding mountain roads. In practice xDrive provides any required shift of torque and drive forces between the axles with maximum efficiency in the shortest possible time. This, in turn, is a significant advantage for the driver, the flow of power being consistently adapted to the driving situation. A few examples: A bearing block is connected to the oil sump on the right to allow the use of two drive shafts exactly equal in length. The advantage is that the steering remains free of drive forces, since the drive shaft deflection angle is the same on both sides, that is at the left and at the right. A further advantage of this configuration is the maximum steering lock provided in this way, with a turning circle of just 11.7 metres (38.4 feet) much smaller than on a conventional offroader. This, in turn, is a significant advantage when driving the X3 under everyday motoring conditions, for example when turning or in a confined car park. The X3 intentionally does without an additional reduction gear as required for extreme offroad motoring. First, because this keeps the centre of gravity as low as possible despite ample ground clearance. Second, because such a reduction gear would not be required on the X3 anyway, considering the purposes for which it is intended. And third, because the weight saved in this way gives the customer a significant benefit. Like all other BMWs DSC Dynamic Stability Control on the X3 can be switched off, giving the sporting driver the opportunity to enjoy the dynamic driving qualities of the X3 in a controlled drift. The xDrive all-wheel-drive system, in turn, cannot be deactivated. HDC for taking downhill gradients in a safe, controlled process.
As on the BMW X5, DSC comprises an additional program offering many benefits off the beaten track: HDC Hill Descent Control, an “intelligent� downhill driving technology for steep gradients. On loose or slippery surfaces, for example, HDC enables the driver to proceed down a hill smoothly and safely, without the slightest effort: Without the driver having to intervene, the X3 – as if it were fitted with a reduction gear – proceeds downhill smoothly and consistently at just over walking pace. Integrated in DSC Dynamic Stability Control, this automatic speed control system operates by applying the brakes individually as required on all four wheels. HDC is activated and deactivated by a separate button in the cockpit. Available at speeds of less than 35 km/h (22 mph), HDC automatically reduces the speed of the X3 in a linear deceleration process to approximately 8 km/h (5 mph), then keeping speed consistently at this level. Now, depending on his requirements, the driver is able to adjust his speed within the HDC control range between 6 and 25 km/h by pressing the “+� and “–� keys on the cruise control in the multifunction steering wheel. And as soon as the driver accelerates above the 35 km/h limit, HDC switches over to the stand-by mode, finally being automatically deactivated at speeds of more than 60 km/h (40 mph). A unique BMW feature: trailer stability control.
Featuring BMW’s innovative trailer stability control, the X3 is ideally suited as a comfortable, safe and high-traction vehicle for towing a trailer. This system offers additional safety against the dangerous risk of instability building up to generate an uncontrolled swerving effect possibly leading to an accident. And it is important to note in this context that the X3 2.5i is able to tow a trailer of up to 1,800 kg (3,969 lb), the two three-litre versions even being able to handle 2,000 kg (4,410 lb). In terms of driving dynamics, any vehicle towing a trailer is subject to a relatively significant risk of body roll or sway, such pendulum action increasing as a function of speed. A heavy trailer may indeed cause a significant risk even at low speeds, the trailer and the vehicle itself, once swaying, no longer being able to regain their stability unless a control system intervenes right away. Trailer stability control recognises such dangerous swaying motion immediately and quickly slows down the vehicle, applying the brakes also on the trailer to reinstate vehicle and trailer stability and once again build up safe driving conditions. The control unit “recognises� that a trailer has been hooked up as soon as the power supply has been connected to the car, thus being activated and serving to intervene as of a speed of 65 km/h (40 mph). This control function is based on constant supervision of the yaw rate signal informing the DSC control unit of any rotating movement of the vehicle. With this signal being permanently supervised, any pendulum motion is recognised by the typical course of the signal detected by the control unit. Then, as soon as the signal exceeds a certain limit, brake pressure is built up on all four wheels, providing 2.5–4 m/sec2 of stopping power without any intervention on the part of the driver. At the same time engine power is briefly reduced to a minimum, the rapid reduction in speed ensured in this way stabilising the vehicle and the trailer very quickly and efficiently. Activation of trailer stability control is displayed by the DSC/xDrive telltale light flashing on and off. Being part of DSC Dynamic Stability Control, trailer stability control is automatically deactivated as soon as the driver deactivates DSC.

Power Units

The BMW X3 is entering the market with three engines that have already made BMW world-famous: These are straight-six power units displacing 2.5 and, respectively, 3.0 litres, the larger of which also comes as a diesel. Considering all relevant features – low weight, compact dimensions, superior fuel economy, and low exhaust emissions – BMW’s six-cylinders are unparalleled. Measuring approximately 80 centimetres (31´´) in length, these straight-six power units are among the most compact of their kind. Then there is the well-known advantage that six cylinders in series are not just absolutely free of free mass forces, but also do not have any mass momentum. The result is turbine-like running smoothness throughout the entire speed range. Together with low weight and the very good streamlining of the X3, the engines offer absolutely outstanding performance and fuel economy: The X3 3.0i accelerates from 0–100 km/h in 7.8 seconds, the X3 3.0d takes just a tenth of a second longer. Midrange acceleration from 80–120 km/h (50–75 mph) in fourth gear takes only 7.7 seconds in the X3 3.0i, the diesel model completing the same exercise a whole second faster. The performance data of the X3 2.5i was not yet final at the time of print. Both the X3 3.0i and the X3 3.0d have a top speed in standard trim of 210 km/h (130 mph). An option available with the Sports Package for the three-litre engines is the special high-speed set-up using special, high-speed V-rated tyres to provide a top speed of 224 km/h (139 mph) on the 3.0-litre petrol model and 218 km/h or 135 mph on the diesel. A further forte of BMW’s six-cylinder power units, despite all their dynamic performance and muscle, is superior economy: The X3 3.0i consumes just 11.4 litres/100 km in the ECE driving cycle (one-third urban, two-thirds extra-urban) with manual gearbox, equal to 24.8 mpg Imp. The X3 3.0d, in turn, is even more fuel-efficient, consuming just 8.4 litres of diesel fuel (33.6 mpg Imp) in the same combined cycle. Applying these figures, the X3 3.0d offers a range of 800 kilometres or almost 500 miles on one tank full of fuel (67 litres/14 3/4 Imp gals). Petrol engines with outstanding refinement and running qualities.
The specifications of the petrol engines are clear and convincing:
BMW X3 chart Infinite bi-VANOS camshaft adjustment, four-valve technology, adaptive knock control and individual coils are the high-tech features through which BMW six-cylinders have been setting the standard for a long time. In their basic configuration the two engines are the same, using special turbulence ducts on each cylinder to refine the resonance intake manifold. This serves to increase flow velocity of the fuel/air mixture at low engine speeds and under minor loads, thus ensuring a better fuel/air mixing process, allowing optimum ignition angles and, accordingly, reducing both emissions and fuel consumption. Combined with the options provided by infinite bi-VANOS, this allows far greater flexibility in preparing the fuel/air mixture than is possible with a conventional system. Exhaust gas catalysts with metallic substrates combining high cellular density with slender walls close to the engine, in turn, ensure full maintenance of both the ULEV and EU4 emission standards, entitling the owner of an X3 to lower taxation in Germany. Highly sophisticated cylinder charge management: bi-VANOS.
The term “VANOS� is short for Variable Camshaft Adjustment, a system developed by BMW for concurrent management of exhaust emissions, engine output and torque in order to optimise the idling quality and fuel economy of the engine. The principle applied in this case is an adjustment mechanism serving to change the position of the camshaft relative to the crankshaft, thus providing variable valve timing. Bi-VANOS, in turn, is a valve control system adjusting both the intake and the outlet camshaft. The system controls the reflow of hot exhaust gas into the intake manifold under all running conditions, that is with any conceivable combination of engine load and speed. This is therefore referred to as internal reflow of exhaust gas, the amount of exhaust gas flowing back being dosed very accurately in the process. While the engine is warming up, VANOS improves the fuel/air mixture and helps to raise the temperature of the catalytic converter as quickly as possible to the normal operating level. When idling, in turn, the system ensures smooth running conditions thanks to the reduction of exhaust gas reflow rates to a minimum. These reflow rates are then increased when running under part load, allowing the engine to run with its throttle butterfly further open in the interest of enhanced fuel economy. Under full load, finally, the system once again reduces the reflow rate in order to fill a maximum amount of oxygen into the cylinders. All-electronic throttle butterfly.
To dose the driver’s commands as precisely as possible in stop-and-go traffic and, at the same time, to ensure immediate response of the vehicle whenever the driver needs more power, the two petrol engines come with an all-electronic throttle butterfly. This sophisticated unit “sees� in what gear the vehicle is currently being driven and is therefore able to activate an individually programmed throttle butterfly control map for each gear ratio. A further advantage of the electronic throttle butterfly is the smooth transition from one driving status to another, for example from overrun to part load and vice versa. Low cost of service.
BMW’s straight-six power units are convincing proof of the great attention BMW gives to the need for economy in the design and configuration of the drivetrain: Diesel engine with the second-generation common rail system.
An ultra-strong and economical alternative to the agile petrol engines in the BMW X3 is the direct-injection diesel engine which has already made a great name for itself as a genuine sports diesel in BMW saloons. The engine’s specifications are as follows:
BMW X3 chart Perhaps the most important factor contributing to the engine’s superior power, dynamism and economy is BMW’s second-generation common rail system with significantly higher injection pressure and volume control: Maximum system pressure is up from 1,350 to 1,600 bar, injecting fuel even faster and ensuring an even better process of atomisation, in the interest of extra power and greater fuel economy. A further point is that this sophisticated injection process does not always compress the entire amount of fuel delivered to maximum pressure, but only, thanks to volume control, as much fuel as the engine needs at any given point in time. The reduction in energy required by the high-pressure pump achieved in this way makes a significant contribution in reducing fuel consumption. The option to inject fuel up to four times in each operating cycle solves the conflict of interests between output and noise management: Double-pilot, main and post-injection improve the entire process, the double-pilot phase making combustion even softer and more harmonious while post-injection improves the oxidation of particles and reduces the emission of harmful substances accordingly. As a result, the X3 3.0d easily outperforms the EU 3 emission standards, optimised blade geometry and the use of high-strength materials improving turbine and compressor efficiency of the turbo-charger once again. Digital Diesel Electronics with running smoothness control.
To capitalise in full on all the options offered in particular by the latest generation of common rail technology, Digital Diesel Electronics has been further developed into the DDE5 generation serving, inter alia, to enhance running smoothness and refinement by means of a new crankshaft sensor with digitalised signal output and enhanced control of the rapid heating system. DDE5 operates with electronically controlled 6 V low-voltage spark plugs where only the tip of each plug is heated to peak temperature, which in practice allows the engine to start even more spontaneously, reach higher terminal temperatures, reduce its uptake of electric power, and keep dimensions even more compact. As a result, the driver is able to start the engine spontaneously, without even waiting, at temperatures down to 5 ºC. And even in very cold temperatures down to –20 ºC starting the engine takes only two seconds. Using “intelligent� self-learning functions for the first time, the variation of injection volumes in the individual cylinders is further reduced, providing a standard of comfort and refinement truly excellent in the SAV segment. Six-speed manual or five-speed automatic.
All models in the X3 range come as standard with a manual six-speed gearbox meeting all the requirements the driver of a sporting SAV would expect in the X3: short gearshift travel, a crisp, precisely controlled and short gearshift lever, plus optimum gear increments. This allows the driver, first, to use the high torque of the engine at virtually every road and engine speed, while as the second point also driving the X3 “lazily� and without giving up too much agility in the process. And the transmission comes in all cases with a lifetime oil filling. The engine and manual gearbox are connected by a self-adjusting clutch built to convey consistent pedal forces regardless of wear. This makes the clutch absolutely reliable, without requiring any service during its entire lifetime. Five-speed automatic transmission with Adaptive Transmission Management (ACM), a fully controlled converter clutch and Steptronic is available as an option.

Safety

It almost goes without saying that the X3 fulfils all of BMW’s very demanding safety standards, without making the slightest concession. Like the X5, it is indeed designed and built consistently for superior safety resting to begin with on its unitary body structure. This means not just significant advantages in comfort and driving behaviour, but also great benefits in passive safety. Indeed, the body of BMW’s compact SAV is in a position to absorb a lot more crash energy even before restraint systems such as the belts and airbags cut in, thus maintaining the high standard of safety offered by BMW saloons. Unitary all-steel bodyshell for optimum safety and stiffness.
To reach the most ambitious objectives in terms of structural dynamics, stiffness and safety, BMW’s engineers have given the X3 a unitary all-steel body structure in functional lightweight design. This means consistent use of high-strength steel and load-based configuration of all bearing elements providing ample safety reserves throughout the vehicle’s entire lifecycle. And it is why nearly all the panels used on the body are hot-galvanised. Top priority in protecting the occupants is given to full maintenance of the survival area required, a factor making great demands of the passenger cell structure particularly in severe accidents. To take up energy in a head-on collision, the engine subframe is a rectangular, longitudinal unit with bolted deformation elements connected at the front to a flexurally-stiff bumper crossbar. And whenever deformation travel ahead of the front axle subframe is not sufficient, the longitudinal arms are able to deform in a controlled process all the way back to the bulkhead. Door reinforcements with built-in hooks for effective protection in a collision from the side.
The doors made of steel plate and featuring high-strength hinges and door locks provide superior protection in side-on collisions. Diagonal door reinforcements made of high-strength steel profiles take the varying height of bumpers on other vehicles into account, the door reinforcements furthermore “hooking� on to the side frame to form an additional load path from the door to the body. In real-life accidents this reduces maximum intrusion in absolute terms as well as the actual rate of intrusion. A further important feature is the front seat structure with high-load-resistant crossbar supports beneath the rear seat shell area and in the backrests providing maximum survival space in a side-on collision. The BMW X3 comes with up to 8 airbags, driver, front passenger and head airbags as well as side airbags at the front all fitted as standard. And at the rear side airbags are available as an option. The airbags on the driver’s and front passenger’s sides are in so-called SMART technology, inflating in individual steps as a function of impact severity. The airbags comply with the latest US standards for minimum exposure of small children and occupants in so-called “OOP� positions. “OOP� stands for “Out Of Position�, that is situations in which the occupant is not leaning back in his seat, but instead is bending, say, to the front or leaning to the side. Standard: curtain head airbags on all side windows.
The four occupants sitting at the outside are protected as standard by curtain head airbags in a collision from the side. These head airbags genuinely similar to curtains are concealed beneath the panel on the A-pillar and roof liner. Positioned to the side of the occupant’s head both front and rear, the curtain airbag covers the complete side window. With its volume of approximately 29 litres, it inflates into a rectangular area measuring 2,100 x 400 mm (83 x 16´´ ). In the event of a crash the curtain airbag serves, first, to reduce any dangerous side motion of the occupant’s head, which might over-strain his neck. Second, the curtain airbag avoids any contact with objects intruding into the car from outside and, accordingly, any direct injury to the occupant’s head, for example when hitting a tree sideways. In a side-on collision only the side airbags facing the point of impact are activated, reserving the possible inflation of the opposite airbags for a secondary impact, where applicable. A further advantage of this safety strategy is that it reduces the cost of repair. Greater safety in the event of a flat: the TPI Tyre Pressure Indicator.
Following MINI and the BMW 5 Series Saloon, the X3 is now the third large-scale production car built by the BMW Group to feature a tyre pressure control system fitted straight at the factory. Gradual loss of air involves a significant risk of accidents, since tyres may overheat and suddenly burst while driving. The TPI Tyre Pressure Indicator monitors tyre pressure consistently by comparing the speed of the wheels on the road, using the ABS signals for this purpose. Any irregularities caused by a drop in pressure are signalled to the driver by both a warning light and a sound signal, regardless of the make of tyre or whether the driver is taking a bend, driving at high speeds or travelling under adverse road conditions such as wet or snowboard surfaces. The system provides a reliable warning as of a road speed of 15 km/h or 9 mph, and with tyre pressure dropping by more than 30 percent. The Tyre Pressure Indicator reliably informs the driver of any sudden and excessive loss of pressure, too. It is therefore even able to detect a “gradual� flat, with air escaping only slowly. However, it always remains the driver’s responsibility to check air pressure in the tyres regularly, reactivating the system after every change of tyre pressure and when switching to a new tyre before re-entering the target pressure level.

Interior and Equipment

In particular, the X3 experience gives the passengers a unique feeling of space and freedom. The high seating position also referred to as the “commanding� position, together with ample headroom, ensures a genuine touch of generosity, while at the same time the interior fits the driver and passengers like a tailored suit, thus avoiding any feeling of undue distance. Expressed in figures, the driver and front passenger enjoy 1,417 mm (55.8´´) shoulder room, that is 35 millimetres (1.4´´) more than in the 3 Series Saloon, as well as 997 millimetres (39.3´´) headroom, 22 millimetres (0.9´´) more than in the 3 Series. Seating accommodation is equally comfortable for the rear-seat passengers, 590 millimetres (23.2´´) knee room giving even tall occupants all the space they need. And headroom of 1,002 millimetres (39.4´´) even exceeds the space available in the generously dimensioned new 5 Series. Up to 1560 litres of luggage space.
Lots of space is also available in the luggage compartment ranging in size from 480 litres (up to the luggage compartment cover) all the way to 1,560 litres, making the luggage area comparable to the space available in the X5. Folding down the backrest on the asymmetrically split rear seats to provide an almost flat surface, the driver can load up to three mountain bikes into the luggage compartment. And as an option the bikes – or any other cargo, for that matter – can be stowed away very safely and conveniently thanks to two optionally available fastening rails with four moving and firmly positioned lashing points in the floor of the luggage compartment offering ideal transport options for all kinds of sports equipment and other items thanks to the accessories available. With the single-piece tailgate opening up to a wide angle and thanks to the low floor level in the luggage compartment, the process of loading and unloading bicycles is nothing but child’s play. Small odds and ends, in turn, fit conveniently into an additional storage box at the rear right, and a 12 V power socket featured as standard in the luggage compartment provides electric power for appliances such as a cooling box. Again reflecting the versatility and practical value of the X3, a wide range of storage compartments, boxes and fastening options are within easy reach of the passengers. Two cupholders in the centre console at the front are standard even in the “basic� model. Spacious map pockets complete with nets in the front doors serve to accommodate all kinds of odds and ends, the glove compartment providing a capacity of 4.5 litres. The armrest in the centre console, in turn, offers two separate storage boxes, a flatter compartment at the top housing the optional telephone where fitted and a larger compartment further down accommodating the optionally available six CD player as well as three additional CDs. The rear-seat passengers have the convenience not only of pockets in the doors, but also two cupholders and a storage compartment in the centre armrest. Two standardised child seats may be fastened on ISOFIX attachment points at the rear and the optional ski-bag allows clean and safe transportation of up to four pairs of skis even with four occupants in the vehicle. Whenever the ski-bag is not required, in turn, it fits conveniently, out of sight and without taking up any space behind the centre armrest. The driver seeking to take along even bulkier cargo has the choice of the optional storage package comprising nets behind the front seats in the front passenger’s footwell, and in the luggage compartment at the rear left. A further feature in this case is the additional storage compartment at the top middle of the instrument panel housing the folding colour monitor on vehicles fitted with BMW’s navigation system. And last but not least, the package comes with fastening rails in the luggage compartment comprising four variable lashing points and a slip-proof double-sided floor mat. Sports seats are available as an option for both the driver and front passenger, suitably contoured side elements on the seat squab and backrest providing optimum side support in all situations. Seat height, backrest and seat angle, fore-and-aft position as well as thigh support are all electrically adjustable. Your personal X3: Car and Key Memory.
Like all new BMWs, the X3 comes with the Car and Key Memory personalisation functions. The former, Car Memory, serves to program a wide range of individual settings, for example automatically switching on the lights when the driver starts the engine or activating the follow-me-home function after you have locked your car. In this case all the driver has to do is press the light flasher when getting out to keep the headlights on for approximately 40 seconds, thus brightening up the area around the car. Over and above these functions, Key Memory “remembers� a wide range of personal settings for each individual driver in conjunction with the respective remote control key. This enables the driver to activate, say, his “personal� setting on the air conditioning and, on models fitted with power seats, his personal seating position when opening the central locking. The BMW X3 comes as standard with an on-board computer comprising a wide range of functions: time, outside temperature with an acoustic black ice warning as soon as temperatures drop below +3 ºC, average fuel consumption, the range still remaining on the fuel in the tank, and your average speed. The driver is informed of these functions in his primary line of vision in the lower middle section of the instrument cluster. This and the simple operation of the on-board computer by means of buttons on the direction indicator lever make sure that the driver will never be distracted from the road around him.

Optional Extras

Over and above the wide range of standard features, the BMW X3 comes with an equally wide range of options. Particular highlights in this context are the new, extra-large panorama roof and the innovative Adaptive Headlights. Adaptive Headlights with bi-xenon light units.
Introducing new Adaptive Headlights, BMW is offering yet another networked active safety system in the X3. Adaptive Headlights have been developed to enhance active safety at night, improving driver visibility in the dark by means of swivelling headlight units. The two bi-xenon headlights are controlled in their position as a function of the steering angle, yaw rates and road speed, thus illuminating the road ahead in a bend. The driver activates the Adaptive Headlights by way of the lights switch in the Automatic position, the adaptive function being triggered as soon as the car starts moving. Whenever the wheels are turned to the left with the car at a standstill (or to the right in the case of right-hand-drive models), the headlights must point straight ahead for legal reasons in order to avoid dazzling oncoming traffic. And when backing up the Adaptive Headlights remain inactive. The basic component incorporated in this adaptive system is the swivelling headlight module with bi-xenon lights for the high and low beam. Further features of this system are dynamic headlight range control as well as the headlight cleaner. Panorama roof.
The two-piece panorama roof extends almost throughout the entire roof area, with a glass surface of 0.65 square metres. The driver is able to open the roof completely just by touching a button, providing a genuine convertible feeling within a Sports Activity like the X3. When opening, the front glass panels move beneath the rear panels, largely disappearing between the roof and the interior lining. To protect the passenger compartment from overheating the glass panels in the panorama roof are made of venus-grey protective glass, and the glass area may also be covered by a suspended lining opening and closing fully automatically. Bi-xenon headlights.
The bi-xenon headlights use the excellent illumination power of xenon bulbs not just for the low, but also for the high beams, thus giving the driver the most powerful lights technology currently available. To provide the low- and high-beam setting, a shutter is moved electromagnetically in front of the light beam within the xenon light unit, varying the beam accordingly. And to avoid the risk of dazzling oncoming traffic, the system is combined with dynamic headlight range control. Electrochromatic interior mirror.
The electrochromatic (EC) mirror is made up of two glass plates, one clear and one reflecting plate, with an ultra-thin fluid film in between. As soon as this film comes under electrical voltage, it changes its permeability to light and the mirror grows dark. This entire process is controlled by two light sensors in the interior mirror constantly comparing ambient light and mirror brightness and thus determining whether the driver might be dazzled by the headlights of vehicles following from behind. Depending on specific requirements, the system reduces the degree of mirror reflection infinitely by 60–10 per cent. Climate comfort windscreen.
The infra-red-reflecting windscreen consistently reduces any excessive heat caused by solar irradiation. Particularly after being parked for a long time in summer, the vehicle may become very hot inside, the climate comfort windscreen thus reducing the temperature of interior components now far more pleasant to touch. As an example, surface temperature on the instrument panel is reduced by approximately 10 ºC after parking the car for 90 minutes in bright sunshine. While driving, in turn, the reduction of solar irradiation enhances not only motoring comfort but also driving safety, with the interior temperature having a significant influence on the driver’s ability to concentrate at the wheel. Navigation system with DVD.
The X3 is available as an option with a DVD-based navigation system in two different versions: The Professional navigation system features a coloured, high-resolution 16:9 graphic display presenting maps of the route calculated and providing navigation instructions by voice messages. The display folds out electrically and is perfectly accommodated in the top middle area of the instrument panel, even offering an optional TV function. The alternative is the Business navigation system with destination guidance by voice messages and arrows presented in the radio display. Both systems take RDS-TMC traffic information received on the radio by digital data flow into account, any further messages relating to the planned route and traffic conditions also being presented and, at the request of the driver, taken into consideration in the route planning process. The driver is also able to choose the dynamic route planning option, with the system automatically calculating the best route to the destination required. And if in this case traffic congestion might arise on the route calculated, the system will judge itself which alternative is best. Should this indicate that the route chosen is faster despite such traffic congestion, the navigation unit will proceed accordingly. Car telephone.
BMW offers purchasers of the X3 wishing to telephone in their vehicle various options and technologies: The highest level of equipment is the Professional car telephone incorporating Bluetooth technology and featuring not only hands-free operation and an outside aerial, but also a mobile handset integrated in the centre armrest at the disposal of all passengers for their requirements. In this case the link to the actual mobile phone is provided by trendsetting Bluetooth technology, the telephone itself being controlled either via the mobile handset or the on-board monitor. The entire system is a dual-band configuration and also features control buttons for the telephone integrated in the multifunction steering wheel. The alternative is a system preparing for subsequent use of a mobile phone with a Bluetooth interface including hands-free operation, a charge socket, and an outside aerial. In this case the user need not even take his Bluetooth-compatible mobile phone out of his pocket or place it in an appropriate support, the telephone automatically creating the link with the base station within the vehicle as soon as it is within the range required. Using various separately available snap-in adapters, the user is therefore able to hook up all kinds of Bluetooth-compatible mobile phones also operated if required through the on-board monitor. The third variant, finally, is conventional preparation for a telephone complete with hands-free operation. Audio systems.
A range of high-quality audio and loudspeaker systems giving the customer his personal choice ensures good entertainment within the X3 at all times. The foundation is provided by a high-quality stereo system complete with a CD player fitted as standard in Germany. The BMW Business CD HiFi system, in turn, is available as an option, ensuring listening quality of the highest standard. This audio system comes with a diversity aerial, an integrated CD player with comfort functions, and the option to connect a CD changer. And integrated in the Professional navigation system, BMW Business is also available with a minidisc player instead of the integrated CD player. The optional CD changer for six CDs is accommodated conveniently and within easy reach in the centre console. Given these features, the BMW Business audio system belongs to the range of navigation systems available in the X3. All sound systems come with two central woofers for particularly strong and well-balanced bass quality. A HiFi loudspeaker system with 8 speakers and its own 160 W amplifier is also available, the top version being the Professional HiFi system incorporating 10 loudspeakers, 500 W output and the DSP Digital Sound Processor complete with a graphic seven-band equaliser providing the possibility to generate all kinds of surround sound effects for various types of music. A special satellite radio for satellite broadcasting now available virtually nationwide is furthermore available as an option in the USA. PDC Park Distance Control.
Parking the X3 is child’s play whenever the vehicle is fitted with PDC Park Distance Control introduced by BMW into the market: The closer you get to an obstacle, the faster the sequence of signals presenting the distance between the vehicle and another object. In this process the control unit, using ultrasound and applying the echo principle, cyclically measures the distance from the front and rear bumpers to the nearest obstacle. The sensors cover a detection range of approximately 1.5 metres, with the first warning signal being generated at a distance of approximately 1.2 metres. Then, as soon as the sequence of signals picks up speed increasingly and becomes one continuing tone, the driver knows that he is less than 20 centimetres away from the obstacle closest to his X3. Rain sensor masterminding the screenwipers and headlights.
AIC Automatic Intermittent Control complete with a rain sensor cleans the windscreen with particular efficiency according to current requirements. Available in conjunction with the headlight cleaning system, AIC varies the intermittent wipe interval as a function of moisture on the windscreen in an infinite process from ongoing operation all the way to a complete standstill. To provide this function the rain sensor, considering the reflection of infra-red light, measures light permeability on the windscreen by means of a light diode: A dry window reflects infra-red light 100 per cent, a wet window reflects such light only in part. This guarantees optimum wiper frequency geared to actual requirements as a function of rain intensity. The rain sensor also serves to control the car’s headlights: Whenever the driver turns the lights switch to the automatic position, the headlights are switched on automatically as soon as ambient light drops below a certain level. When driving, say, on routes through the mountains with many tunnels, this function enhances both driving comfort and safety. Sports package.
Available as an option, the sports package gives even greater emphasis to the very dynamic performance and appearance of the X3. The looks of the vehicle in particular are upgraded by features such as white direction indicators, appliqués in high-gloss satin chrome, and light-alloy wheels in star-spoke design. High-gloss satin chrome comprises the surrounds on the side windows as well as the window shaft covers and the mirror base, all finished in high-gloss black paint. The interior, in turn, is upgraded by a leather sports steering wheel, sports seats for the driver and front passenger, as well as the roof lining in Anthracite providing a particularly sporting touch.

The Market for the BMW X Family

The new BMW X3 opens up a new segment in the Sports Activity Vehicle (SAV) market. The original in this segment was and is the BMW X5 creating a market of its own right from the start through its refinement, supreme sportiness, elegance, finish, design and character. So it is no exaggeration to claim that the X5 is a genuine USP. Now the X3 picks up these special features of a BMW SAV without making the slightest compromise, interpreting these features in a unique, youthful and fresh manner as the pioneer in its category. This means that the X3 meets precisely the demands and expectations of the market in this range where so far customers did not have the choice of a premium SAV. BMW X models with unmistakable style.
Particularly the early generations of Sports Utility Vehicles were a rather unusual combination, blending space concepts with traditional offroad features, placing the emphasis primarily on practical value and robust motoring through their design alone. The BMW X Series takes up these aspects through its two-box design as well as the high seating position, providing a new, typically BMW interpretation with the greenhouse moved further to the rear and short overhangs at both ends. Contrary to a conventional SUV, a BMW SAV has far more emotional and modern design language, with truly dynamic looks provided by the muscular, athletic flanks all along the vehicle. Right from the start, the front lid rising up in a sporting line distinguishes the dynamic design of a BMW Sports Activity from a classic offroader. And at the same time this design offers practical benefits, the drag coefficient of the X3 (0.35) and the X5 (0.36) being far better than the drag coefficient of most SUVs, which, in practice, means greater fuel economy particularly at high speeds. And it is precisely at such high speeds that most drivers use their SAVs in practice, with these vehicles serving as ideal leisure-time and weekend activity vehicles outside of town. BMW X models – driving pleasure with a wide range of benefits.
Considering new customer demands in terms of design, expectations in the SUV market have increased considerably in recent years, customers now demanding driving features comparable to those of a saloon. But in many cases manufacturers have responded only by focusing on motoring comfort at the expense of driving characteristics. By contrast, BMW’s engineers responsible for developing the X models have given particular attention to the optimum synthesis of comfort and driving dynamics as well as motoring safety. The driving experience alone, therefore – leaving aside ground clearance and the seating position – is comparable to that provided by a BMW saloon, ensuring supreme driving pleasure in every respect, whether on the road or off the beaten track. Through its low centre of gravity, the X3 is able to minimise body sway and, in conjunction with relatively low unladen weight of 1,760 kg/3,881 lb (X3 3.0i/EU) and the new xDrive all-wheel-drive system, enhances the agility and handling of an all-wheel-drive vehicle to a level of perfection never seen before. Unmistakable style and unique driving pleasure for the customer.
Customer enquiries in Munich clearly show that style and driving behaviour are the most important reasons for purchasing a BMW of this kind, followed by safety and performance. And this again proves that the BMW X-models have exactly the right concept for the market. While the option to drive an SAV on rough terrain is important, this is not the primary factor for the customer. Indeed, most customers use their vehicle’s offroad abilities only once a year, and only one out of five customers use these offroad qualities once a month. Even in the USA customers give utmost significance to the “excellently engineered vehicle�, with safety features and driving pleasure following next as second priority. Market continuing to develop dynamically.
Sales figures consistently increasing in all markets clearly confirm the successful philosophy of the BMW X family: With more than 100,000 X5s sold in 2002, thereof 39,500 in Western Europe and 42,700 in the USA, the success of this vehicle is clear. Indeed, particularly sales of the X5 in Europe are impressive, since here the market shares of SUVs still lag far behind the their market penetration in the USA: Out of 6.34 million SUVs sold worldwide in the year 2000, some 4 million went to customers in America, only 700,000 to customers in Europe. The SUV and SAV segment is and remains the fastest-growing segment throughout the worldwide car market. In the next 10 years experts see ongoing growth of the overall SUV segment by approximately 50 per cent, sales in the X3 segment exceeding even this figure by far. In this process customer expectations are becoming increasingly ambitious, most customers looking for a premium vehicle regardless of size. And precisely this is where BMW is going with the new X3, a Sports Activity measuring 4,565 millimetres or 179.7´´ in length and fulfilling the greatest demands. Especially as the X3, a pioneer in its class, has no direct competitor.

Production

The new X3 is the only model in the current range of BMW Group vehicles not to be built in a BMW Group plant. Instead, the X3 Sports Activity comes off the production line at Magna Steyr Fahrzeugtechnik AG & Co. KG (MSF) in the Austrian town of Graz. Cooperating with MSF, the BMW Group has found a partner with years of experience in the implementation of vehicle projects, MSF regularly receiving top grades in the renowned J.D. Power & Associates quality studies. MSF has built a new bodyshop and assembly line exclusively for the X3 in Graz, from where the vehicle goes through BMW’s distribution system to all markets the world over. This production system is able to respond flexibly to demand, the plant providing a capacity of more than 300 vehicles a day. Project-related expenditure so far has been approximately Euro 500 million and some 2,500 employees work in the production of the X3. MSF was involved in series development of BMW’s new SAV almost from the start, following the detailed concept of the vehicle determined and masterminded by BMW’s engineers. Core competences such as design, engine applications, approval and clearance of the overall vehicle, purchasing and customer service, however, have remained the sole responsibility of BMW from the start. Using the additional engineering capacities and project structures offered by MSF, BMW has been able to develop the X3 concurrently to other vehicle projects. Such outsourcing production concepts based on intelligent joint ventures increase the capacity and, accordingly, the flexibility of the BMW Group according to demand in the market. And indeed, concepts of this kind in expanding BMW’s core capacities have already been applied in the past, for example for the BMW 02 Convertibles, the M1 and a number of motorcycle projects all handled in cooperation with external partn BMW X3 specs chart
