BMW X5 E70
Sports Activity Vechicle (SAV)
Offering enhanced dynamics and an even higher standard of all-round supremacy, the new BMW X5 E70 is finally here. When introducing the former model, the first X5, BMW set up and established the brand-new segment of the SAV Sports Activity Vehicle. As a spacious, luxurious, versatile and, at the same time, robust premium car offering excellent qualities through its electronically controlled all-wheel drive and superior driving dynamics for venturing out on rough terrain, the BMW X5 E70 hit the headlines right from the start. And the success of this strategy is clearly reflected by more than 580,000 units sold worldwide in the meantime.

Driving dynamics typical of BMW – unique in the SAV segment
Throughout its entire production cycle, the first SAV in the world was able to maintain its status as a benchmark in driving dynamics. Now, introducing the new BMW X5, BMW’s drivetrain and suspension specialists have lifted the yardstick for performance, agility, dynamics and suspension comfort to an even higher level.
The driving experience is characterised, as before, by significant ride height and a commanding seating position. Further fortes also maintained in the new model are the unitary bodyshell, independent suspension, and permanent, electronically controlled, variable all-wheel drive.
Both the gasoline and diesel engines with eight and, respectively, six cylinders have been significantly optimised to an even higher standard of excellence. And the suspension, finally, is brand-new from the ground up, conveying the power of the engine in superior style to the road or, as the case may be, to a rough track.
A feature quite unique in the SAV segment is the combination of a double wishbone front axle with the integral IV rear axle in the new BMW X5.
This cutting-edge configuration allows a particularly high standard of lateral acceleration, extremely good directional stability, and exemplary roll comfort all at the same time. Yet another innovation is rack-and-pinion steering with its variable transmission ratio facilitating a precise style of motoring in its middle position while offering the driver a more direct response in bends with a larger steering angle.
The new BMW X5 is the first vehicle in its class available as an option with Active Steering including Servotronic. This unique steering system adjusts the steering transmission ratio additionally to the road speed of the vehicle in the interest of an even higher standard of agility. At high speeds Active Steering provides even safer directional stability, while when parking or manoeuvring all the driver has to do is turn the steering wheel twice from its extreme left to its extreme right position.
A further benefit of Active Steering in the new BMW X5 is the active contribution it makes to stabilising the vehicle. When applying the brakes on different surfaces, for example, that is with a different frictional coefficient on either side, Active Steering provides an appropriate but discreet counter- steering effect to prevent the vehicle from swerving out of control.
World debut: AdaptiveDrive with data transfer via FlexRay
The new BMW X5 is the first SAV in the world available as an option with AdaptiveDrive providing carefully coordinated interaction of the anti-roll bars and dampers. Incorporating the vehicle’s sensors, AdaptiveDrive permanently monitors and calculates data on the speed of the vehicle, the steering angle, longitudinal and lateral acceleration, body and wheel acceleration, as well as ride height. Using this information, the system then masterminds both the sway motors in the anti-roll bars and the electromagnetic valves on the dampers, thus adjusting the side angle and damping of the new BMW X5 appropriately at all times.
To ensure fast and reliable coordination, AdaptiveDrive for the first time uses the FlexRay high-speed data transmission system.
The new BMW X5 and the xDrive system
Even greater precision: intelligent BMW xDrive all-wheel drive technology.
Electronically controlled, variable BMW xDrive offers an even higher standard of precision than before in the new BMW X5. The particular strength of this intelligent all-wheel-drive system introduced by BMW is its ability to significantly enhance traction on rough terrain as well as driving dynamics under all conditions.
In a normal driving situation, permanent all-wheel drive distributes engine power 40 : 60 front-to-rear. The system then responds quickly, precisely and variably to any change in surface conditions or the driving situation, instantaneously varying the distribution of drive forces as required: Via a power divider with an electronically controlled multiple-plate clutch, BMW xDrive feeds the power of the engine precisely to the wheels where it can be used best and most efficiently.
As a result, xDrive enhances driving dynamics in the new BMW X5 by counteracting even the slightest trend to over- or understeer in bends at the earliest point. A further advantage is that BMW xDrive supports the vehicle’s traction and performance off the beaten track, ensuring maximum traction also on rough terrain by feeding drive power instantaneously and variably to the wheels currently enjoying a higher frictional coefficient.
Integrated Chassis Management with optimised control quality
To ensure fast and precise distribution of drive forces, the xDrive all-wheel-drive system, DSC Dynamic Stability Control, engine management and Active Steering all interact with one another via BMW’s Integrated Chassis Management. As a result, the distribution of drive forces, individual intervention in wheel brakes, and engine management are all fully coordinated with one another.
Again, this all-round suspension control philosophy ensures the highest conceivable standard of both driving dynamics and active safety.
DSC with additional functions
Apart from driving stability control, the basic functions of DSC comprise of ABS anti-lock brakes, ASC Automatic Stability Control, Trailer Stability Control, HDC Hill Descent Control, DBC Dynamic Brake Control automatically maximising brake pressure whenever required in a forceful braking manoeuvre, as well as CBC Cornering Brake Control preventing the vehicle from oversteering whenever the driver applies the brakes lightly in a bend.
The ADB Automatic Differential Brake electronic differential, finally, acts as a transverse lock between the wheels, automatically applying the brakes on a wheel about to spin.
The regular Dry Braking function, on the other hand, optimises brake performance in the wet. And last but certainly not least, the Start-Off Assistant helps the driver set off on an uphill gradient, without the vehicle rolling back.
The new BMW X5 also boasts a parking brake with both electromechanical and hydraulic functions activated or released simply by pressing a button.
DTC for greater slip and more dynamics
The new BMW X5 also comes with DTC Dynamic Traction Control reflecting the supreme dynamic driving potential of BMW’s SAV. Indeed, DTC is a special mode of DSC tailored specifically to the new BMW X5 and activated by pressing a button on the centre console.
To meet the needs of offroad motoring, DTC raises the threshold for intervention by the engine and brakes, enabling the BMW X5 to set off smoothly on surfaces such as loose snow or sand, with the drive wheels intentionally spinning slightly. And a further advantage of DTC is the sporting and even more active style of motoring it allows on hard tarmac.
First SAV with runflat tyres fitted as standard
The new BMW X5 is the first vehicle in its class fitted as standard with runflat tyres. These safety tyres come on extended-hump rims, the new BMW X5 boasting the fourth generation of runflat tyre technology. Thanks to their stiffer flanks, these special tyres prevent the risk of tyre damage also when driving off the beaten track. And should the driver suffer a complete flat all the same, he can still continue with runflat tyres for a distance of up to 150 kilometres or 90 miles and at a maximum speed of 80 km/h or 50 mph with the vehicle fully laden – and if the vehicle is carrying a lower weight, the driver is able to go on a lot further.
Yet a further feature is the Tyre Defect Indicator warning the driver of a gradual loss of air in the tyres. Any deviation in tyre pressure is determined by comparing the speed of the wheels, the warning then being provided by a graphic symbol in the display of the instrument cluster.
New six-speed automatic transmission with even faster gearshift and enhanced shift comfort
Power is transmitted in the standard configuration of the new BMW X5 by a six-speed automatic transmission likewise enhanced to an even higher standard. This new six-speed automatic shifts gears with incomparable speed, precision, and efficiency, new converter technology and particularly efficient software reducing reaction and shift times versus a conventional auto-matic transmission by up to 50 per cent. And the direct gear detection function enables the transmission to shift down just as quickly when skipping one or several gears, thus not taking up any additional time in the process.
New electronic gear selector
The automatic transmission is shifted by an electronic gear selector also featured for the first time in the new BMW X5. The gearshift pattern as such is the same as on a conventional automatic transmission, but the parking position is activated by a button in the gear selector lever moving back after use to its original position. Transmission management is not mechanical, but rather by electrical signals. To activate the manual gearshift, therefore, all the driver has to do is move the selector lever to the left and then shifting gears sequentially by hand.
Presence and elegance: the design of the new BMW X5
Compared with its predecessor, the new BMW X5 is 18.7 centimetres or 7.4´´ longer and 6.8 centimetres or 2.7´´ wider.
Inside the vehicle, this growth means a significant enhancement of both comfort and functionality, while from outside BMW’s five-door SAV continues to boast a high standard of powerful elegance. Indeed, BMW’s body designers have succeeded in carefully enhancing the proportions of the new SAV, in the process giving even greater emphasis to the overall impression of the vehicle with its particular touch of agility.
This impression is clearly borne out not only by the short body overhangs front and rear, but also by the larger wheels. And at the same time the optical balance of the front and rear section helps to give the new X5 even more harmonious proportions referring directly to the vehicle’s four-wheel-drive technology.
With its longer wheelbase, the new BMW X5 exudes a far higher standard of stability and presence. The stretched side look of the vehicle is limited by the muscular D-pillars, with the merging lines of all pillars helping to provide an appropriately shortened roofline again enhancing the overall look of slender elegance.
Yet a further classic feature of BMW design is the contour line rising up slightly to the rear and coming out most distinctly on the level of the door opener. Starting out behind the front wheel arches, this characteristic contour line embraces the entire rear end of the vehicle, without being interrupted even by the rear light clusters.
Powerful face, muscular rear
The powerfully curved contours of the engine compartment lid, the three-dimensional configuration of the rods in the BMW kidney grille, and the headlight units fully integrated in the side panels all help to give the front end of the new BMW X5 a particularly powerful and dynamic look. At the top, the dual round headlights would appear to be slightly cut off, giving the new BMW X5 a clear and consistent focus.
The rear end also exudes a powerful touch of elegance, the high edge of the rear bumper accentuating the width of the vehicle and, accordingly, its strong and stable stance on the road. This impression is then further enhanced by the horizontal structure of the rear light clusters in typical BMW L-design extending far into the rear lid as such. And last but certainly not least, four light conductor rods give the new X5 a striking and refined look also at night.
Exceptionally good aerodynamics is one of the particular quality features of the new BMW X5 and its special body design. Low lift forces benefit both driving dynamics and safety on the road, the drag coefficient of just 0.33 (BMW X5 3.0si) placing the new model right at the top of its segment also in this respect.
Maximum flexibility: two additional seats in the third row
A further sign of the high standard of flexibility offered by the new X5 is the option to have a third row of seats fitted at the rear right from the start at the factory. This provides two additional seats comfortably accommodating passengers up to a body height of approximately 1.70 metres or 5´7´´.
Both of these rear seats are equipped with three-point inertia-reel seat belts and headrests adjustable for height. To ensure easy access to the third-row seats, the second row of seats may be tilted completely to the front, even with their backrests still upright. Grab recesses inside the C-pillars also facilitate access to the rear. Whenever these additional seats are not required, they may be folded down individually or together completely into the floor of the luggage compartment.
Intelligent lightweight technology: even stronger on almost the same weight
Despite the larger exterior dimensions of the new BMW X5, BMW’s engineers have succeeded in keeping the weight of the new model almost unchanged, while making the body even stiffer than before. In order to reach the goal of combining extra space with greater stability while avoiding any significant increase in weight, BMW’s specialists have focused consistently on lightweight technology. The choice of materials and the arrangement as well as the geometry of load-bearing elements, bars and supports are based on an overall concept designed from the start for maximum safety in a collision combined with superior agility on the road.
Stable passenger cell, wide range of safety features
The most significant passive safety element in the new BMW X5 is the stable passenger cell. Forces acting on the vehicle in the event of a collision are diverted through the engine support arms and the chassis down several load paths in order to prevent extreme loads acting on individual structures.
Inside, the new BMW X5 features not only frontal and hip/thorax airbags, but also curtain head airbags at the side as standard. These curtain airbags inflate whenever required out of the covers on the A-pillars and roof lining, efficiently protecting the occupants in the first two rows of seats from injury should the worst come to the worst.
The interior: functional and refined
The unique driving experience in the new BMW X5 is clearly borne out from the start through the characteristic commanding position enjoyed in particular by the driver. This higher seating position and the arrangement of the instrument panel slightly angled towards the driver create the impression of unrestricted control over the vehicle. The comfort zone on the dashboard in the middle between the driver and the front passenger comprises all functions and displays also for convenient use and scrutiny by the front-seat passenger. A particular highlight directly in the line of vision of both occupants at the front is the iDrive Control Display positioned in the instrument panel at the same level as the circular dials.
Through its slender design and harmonious transition to the door linings, the instrument panel looks both powerful and elegant all in one. In conjunction with the load-bearing element on the centre console tapering out towards the bottom, it creates the impression as if the entire dashboard were hovering freely in space.
Optimum visibility: xenon headlights, adaptive and bending lights
In conjunction with xenon headlights available as an option, the new BMW X5 offers an attractive and highly functional daytime light function provided by the light rings in the dual round headlights. In this case the rings in the two inner headlights transmit a particularly intense light about 100 times brighter than the parking lights, ensuring much better recognition of the car also from a greater distance and making sure that the new X5 is recognised immediately as a BMW due to its particular light design.
Additional comfort when driving at night is provided by High-Beam Assist also available as an option on the new BMW X5. This system automatically switches back to the low-beam headlights as soon as other vehicles are approaching or the distance to a vehicle ahead drops below a certain point. And yet another function is the foglamps serving as bending lights when taking a turn.
High-grade navigation and audio systems serve to enhance grand touring comfort in the new BMW X5 to an even higher standard. A DVD video system for the second row of seats, a CD or DVD changer in the glove compartment, as well as the innovative multi-channel audio system, are among the highlights offered in mobile entertainment.
Even the standard audio system comes with six loudspeakers, while BMW’s HiFi system Professional specially conceived for the reproduction of multi-channel audio sources comes with no less than 16 loudspeakers.
Thanks to the AUX-IN bush fitted as standard, music from external audio sources such as an MP3 player may be fed directly into the vehicle’s loudspeakers.
Further systems naturally also available are the BMW Online mobile internet portal as well as the BMW Assist telematics service. BMW TeleServices are a new amenity now available in the BMW X5: Using the BMW Teleservice Call, the vehicle, whenever required, sends all information important for the workshop automatically to the driver’s BMW Service Partner.
The customer then receives a call from his Service Partner in order to agree on the date of the car’s next service and the work to be done on the occasion.
Supplementing PDC Park Distance Control, the new BMW X5 is also available with a back-up camera significantly facilitating the process of parking and manoeuvring in confined spaces with poor visibility.
In a segment now subject to keen competition, the new BMW X5 once again sets the standard in driving dynamics and agility. No other vehicle combines the features so typical of a BMW with the fascinating qualities of a truly versatile Sports Activity Vehicle stylish and full of presence in its look.
This makes the new BMW X5 the ideal vehicle for the discerning motorist seeking, through the choice of his or her automobile, to express active, individual and independent lifestyle and at the same time enjoy a new dimension of driving experience.
