2010 BMW X5 M

Press release

The modern, sustainable legacy of BMW M GmbH began in 1985 when engineers placed the snarling, race-bred inline-6 engine from the M1 supercar into the production BMW 5 Series sedan, reworked the suspension and brakes, and created the first M5. Through this industry-first combination of attributes, the M5 redefined the capabilities of a sedan with levels of power, precision, balance, and linear control never before imaginable. Since then, finding new ways to expand the boundaries of what is possible with existing BMW models has been the singular purpose of the craftsmen at BMW M. Now the BMW X5 M and the BMW X6 M are the first all-wheel-drive models to offer the remarkable performance, dynamic driving experience, athletic design, and premium quality of a BMW M product.

Both models are powered by a newly-developed 4.4-liter V8 M engine delivering 555 hp at 6,000 rpm and 500 lb-ft of torque from 1500 to 5,650 rpm. This new M engine is the world’s first with a pulse-tuned exhaust manifold encompassing both rows of cylinders combined with high-performance twin-scroll twin turbo technology.

For the X5 M and X6 M, engineers at BMW M pushed the capabilities of BMW’s intelligent xDrive all-wheel-drive system and the Dynamic Performance Control system to manage the power and performance potential of these two new vehicles. The special M suspension includes Adaptive Drive and newly-developed Servotronic power steering. These features combine to push the limits of what was previously possible with a sports-oriented vehicle, and guarantee driving behavior characteristic of a BMW M product: incredible stability and precisely controlled steering qualities abound throughout the performance envelope.

The BMW X5 M and BMW X6 M set new standards of acceleration, lateral grip, steering response, balance, and stopping power among high-performance activity vehicles. Both models accelerate to 60 mph from a standstill in 4.5 seconds and feature impressive delivery of power from the V8 twin-turbo engine which provides maximum torque of 500 lb-ft from 1,500 and 5,650 rpm. From a handling standpoint, both vehicles are notable for superb balance through careful tuning of xDrive, Dynamic Performance Control, and Dynamic Stability Control with M Dynamic Mode for linear buildup of cornering forces. These capabilities place the performance of the X5 M and X6 M on par with the performance of other recent BMW M vehicles.

The athletic character and amazing performance abilities of the BMW X5 M and X6 M result from levels of development never before applied to this type of vehicle. As it did when creating the original M5, BMW M has once again shown that applying new technologies and innovations to a solid BMW production vehicle type will produce startling performance and an exhilarating drive. Both of these new models offer capabilities and dynamic driving experiences which are quite unique, and promise to provide thrills from everyday traffic to the race track.

Exterior Design: BMW M heritage reflecting function, purpose, and style.

The outstanding potential of both models is communicated clearly in their looks and design, their performance-bred heritage presented convincingly by the common design of the front end with its large air intakes.

The hood, front air dam, and headlights are virtually identical on the BMW X5 M and X6 M. Both models feature special gills in the front fenders, as well as model-specific 20-inch light-alloy wheels. The signs of distinction of BMW M are presented in individual style at the rear, confirming the athletic character of each model. The rear diffuser on each model communicates a particularly powerful presence, and the quad tailpipes of the exhaust system are again a signature of BMW M’s masterful work.

Compared with the standard BMW X5 and BMW X6, the body-color surface area on the side skirts are designed to place greater emphasis on their road-going orientations. On both models the body designs fulfill major functions in terms of aerodynamics and the carefully controlled flow of cooling air.

The first modern turbocharged M engine: twin scroll twin turbo technology with a patented exhaust manifold.

Using BMW’s innovative, 4.4L reverse-flow V8 engine with High Precision Direct Injection and twin turbochargers as a basis, the new M engine introduces twin-scroll twin turbochargers and patented exhaust manifold technologies to achieve outstanding thrust and pulling force, while preserving the most compact dimensions possible. Two low-mass twin-scroll turbochargers are positioned together with the catalytic converters in the “V” section between the two banks of cylinders. By reversing the flow of gases through the engine from traditional arrangements, the intake and exhaust ducts are shortened and widened. The result is that pressure losses on the exhaust side are minimized.

The goals: virtually eliminate turbocharger lag while maximizing combustion efficiency and power output. Tremendous power and performance are delivered by the engine in the BMW X5 M and BMW X6 M through a new design and construction principle. The new M V8 engine with twin-scroll twin turbo technology uses a single exhaust manifold with tuned-length runners, incorporating both cylinder banks and connecting cylinders in carefully-selected pairs. This configuration, patented by BMW M and known as Cylinder-bank Comprehensive Manifold (CCM), offers lightning-quick response, a linear build-up of engine power, and a broad, consistent torque curve by feeding each of the twin turbochargers with a “charge pulse” at approximately every 90 degrees of crankshaft rotation, rather than the more traditional “irregular schedule” of charging.

The managed flow of exhaust gas provided by the CCM ensures high-velocity flow of combustion gases. The appropriate separation of exhaust gas flow from different cylinders is maintained until the gas reaches the turbine wheel, spooling the two twin-scroll turbochargers without back-pressure. With maximum boost pressure of 1.5 bar (21 psi), the use of twin-scroll twin turbo technology and the CCM exhaust manifold allows complete exploitation of the benefits of turbocharging.

Immediate response and remarkable thrust characterize the new V8 twin-turbocharged engine from BMW M GmbH. The impressive onset of power is accompanied by unique, engaging engine sounds that accentuate the quick-revving characteristics with the dynamic acoustic effect typical of a BMW M product. The sounds are always civilized, but transform from relatively calm to extraordinarily intense as the boost and revs build from idle. Reflecting the tremendous power of the engine, the turbocharged M V8 is equipped with an advanced cooling system developed specifically for the two new models. One notable feature in this context is the presence of two high-capacity water-to-air intercoolers which consistently optimize performance under the most demanding driving conditions. An aluminum oil sump exclusive to BMW M with a special finned surface guarantees optimum cooling at all times even under an extremely demanding style of driving.

The turbocharged M V8 engine develops its outstanding power with remarkable efficiency. In addition to BMW’s High Precision Direct Injection, both the BMW X5 M and the BMW X6 M are equipped with a range of technologies from BMW’s EfficientDynamics engineering strategy. These include on-demand control of the electric fuel pump, an on-demand compressor for the air conditioner, and a flow-controlled supply of hydraulic fluid to the Active Roll Stabilization system. By operating these features specifically on demand, energy waste is minimized. The engine fulfills the requirements of the US LEV II standard as well as the EU5 requirements in Europe.

M Sports Automatic and M shift paddles on the steering wheel.

Featured for the first time on a BMW M model, the 6-speed M Sports Automatic transmission enhances the high-performance character of the BMW X5 M and the BMW X6 M through its instantaneous response, direct connection to the engine, and a high degree of shifting comfort. The new M Sports Automatic is commanded by an electronic selector on the center console and offers the driver not only the Drive mode, but also Sport and M Manual modes for absolute control of gear selection.

Aluminum pull-style paddles on the steering wheel exclusive to BMW M allow manual shifting (Right for upshifts, Left for downshifts). Upshifts occur significantly quicker than in the past thanks to new technology that reduces torque in the transmission through momentary deactivation of individual cylinders. This significantly enhances the athletic character of the vehicle. In the M Manual mode, each chosen gear is held up to redline in order to give the driver perfect throttle-steering control of the vehicle under the most demanding driving conditions. The transmission does not upshift or downshift automatically in this mode.

A further option in the M Manual mode is to activate the Launch Control feature, which enables the driver to accelerate from a standstill with maximum performance. To activate Launch Control, the driver stops the vehicle, moves the gear selector into the M/S position and activates the Sports Power mode, as well as the M Dynamic mode, or respectively, the DSC-Off mode. Then, with the transmission in stage M1, the driver presses down the brake pedal and moves the accelerator to at least 60% throttle, setting Launch Control to standby. Standby status is confirmed by “starter’s flag” symbol in the instrument cluster. As soon as the driver releases the brake pedal, the vehicle will accelerate with full power in “genuine racing style.” In the process, the M Sports Automatic transmission automatically upshifts at the ideal points, with the fastest possible shifts and optimum wheelspin control. The driver may terminate the Launch Control process at any time by reducing the throttle position.

BMW xDrive and Dynamic Performance Control with a special M setup for optimum dynamics.

The outstanding success of BMW’s intelligent xDrive all-wheel-drive technology is based on quick, electronically-controlled power distribution to the front and rear axles. When combined with the superb, near 50-50 static weight distribution of any BMW, xDrive can prevent the tendency for the vehicle to oversteer and understeer as long as possible, reducing the need for Dynamic Stability Control (DSC) to provide electronic assistance.

BMW’s Dynamic Performance Control was presented for the first time in the BMW X6 and is now featured in the BMW X5 M and the BMW X6 M. Put succinctly, Dynamic Performance Control enhances driving stability in demanding situations and is thus perfectly suited to a powerful M vehicle. Vectoring of torque between the right and left rear wheels (both on throttle and off) significantly improves steering precision and tracking stability at all speeds, with DSC being required to stabilize the vehicle only under extreme lateral acceleration. Ultimately this offers the driver an unparalleled standard of performance, agility, balance, and traction, and re-establishes the benchmarks in drivetrain and suspension technology for all types of performance-oriented vehicles.

In the BMW X5 M and BMW X6 M the potentials of both xDrive and Dynamic Performance Control are maximized by BMW M, with the driver able to activate the M Dynamic Mode (MDM) with the DSC button on the center console or the steering wheel-mounted M Button. This mode raises DSC thresholds of intervention and ensures throttle-steering behavior typical of BMW M by shifting the xDrive bias more to the rear and involving the Dynamic Performance Control in the process. A pictogram in the Control Display in the instrument cluster allows the driver to monitor the activity of Dynamic Performance Control and xDrive through a clear visual depiction, which shows the driver how much power is being distributed to each wheel.

As a result, M Dynamic Mode allows maximum speeds in bends and on winding roads with the DSC system intervening only when the vehicle reaches the absolute physical limits of grip. Even under maximum load in the apex of a bend, the vehicle follows steering inputs with tremendous precision, giving the driver very high speeds when exiting a turn in the interest of optimum performance. Last but not least, DSC may be completely deactivated by experienced drivers at the touch of a button.

Beyond the stabilizing effects of Dynamic Stability Control provided by individual brake activation and engine power reduction under extreme conditions, DSC in the BMW X5 M and BMW X6 M includes a wide range of additional features tuned to BMW M standards to promote safe and exciting driving. These include ABS anti-lock brakes, Trailer Stability Control, Hill Descent Control, Dynamic Brake Control which maximizes brake force when required, Cornering Brake Control for advanced trail-braking, Brake Fade Compensation for extreme driving conditions, automatic Brake Drying when the windshield wipers are activated, Start-Off Assistant for driving on steep hills, and a braking function for use by the standard cruise control.

Both vehicles come with an electrohydraulic parking brake which features the Autohold (Auto H) function. Auto H is a convenience feature that holds the vehicle in position as soon as it comes to a stop at an intersection or in stop-and-go traffic, without requiring the driver to hold constant pressure on the brake pedal. As soon as the driver touches the accelerator again, the brake is instantly released.

M Suspension with standard Adaptive Drive.

The suspension developed specifically for the BMW X5 M and BMW X6 M with its double-wishbone front control arms and integral four-link rear axle offers M-specific geometry and damping. This is accomplished through optimized control arm and A-arm bushings at the front, as well as stiffer axle support mounts at the rear.

As part of the advanced Integrated Chassis Management system which networks all drivetrain and suspension components, both models feature standard self-leveling rear air suspension and Adaptive Drive with Electronic Damping Control (EDC) and Active Roll Stabilization (ARS). The special version of Adaptive Drive tailored to the requirements of BMW M lowers the entire vehicle by 10 millimeters or 0.4" versus the standard BMW X5 and BMW X6.

To quickly and reliably process data, Adaptive Drive uses the high-speed FlexRay data transmission protocol. FlexRay enables Adaptive Drive to transfer data through the vehicle’s on-board network at an extremely fast rate. This enables lightning-quick changes to settings for individual shock absorbers, swaybars, and other components as conditions and driving demands warrant. For example, if the front wheel encounters a bump, the system responds quickly enough before the rear wheel reaches the same bump. On the X5, X6, and 7 Series, BMW is the first carmaker in the world to use FlexRay as a regular technology.

The special Servotronic steering developed for the BMW X5 M and BMW X6 M provides variable steering assistance geared to the road speed of the vehicle. This allows the driver to negotiate parking maneuvers with lower effort while preserving exact feedback and the highest standard of steering precision at higher speeds.

The degree of power steering assistance is defined by two control maps. Apart from the standard configuration, the driver is able, through the Adaptive Drive button or the M Drive button on the steering wheel, to call up the Sport Mode. This activates a sports driving control map with higher control forces for particularly dynamic driving conditions.

When changing from Normal to Sport Mode, the system alters not only the Servotronic steering control map, but also the damper setting, with the shock absorbers of the vehicle being significantly stiffened in Sport Mode. In conjunction with Active Roll Stabilization, this allows an exceptionally high standard of linear lateral forces in dynamic bends and on fast, winding roads, and keeps body roll to a minimum.

M Brakes and tires to match the M Power.

Outstanding stopping power with fade reduced to a minimum is guaranteed by the high-performance M brake system, which combines giant four-piston fixed calipers at the front with floating calipers at the rear, combined in each case with large, internally-vented lightweight brake discs. The brake rotors themselves measure 15.6” in diameter at front and 15.2” at rear. They feature a riveted connection to join the aluminum rotor hats with the cast-iron rotor discs.

The BMW X5 M and the BMW X6 M are the only vehicles of their type equipped with staggered-size tires front and rear, running on 20-inch light-alloy wheels. The choice of runflat tires in sizes 275/40 R 20 at the front and 315/35 R 20 at the rear is a result of the special setup of both models, with the emphasis on rear-wheel power and dynamic handling balance. This promotes exceptionally good transmission of power to the rear axle and precise, razor-sharp steering behavior of both models. Transitional stability is also world-class.

Maximum performance at the touch of a button: M Drive button on the steering wheel.

In addition to the DSC mode (On, MDM, or Off) and the specific setup of the shock absorbers and Servotronic steering, the driver may also configure the setup of the drivetrain on the BMW X5 M and the BMW X6 M. Activating the Power mode influences both engine and transmission behavior, and the driver can choose from the Sport and Efficiency driving programs. The Sport program allows precise control of engine power under the most dynamic driving conditions, and ensures a linear build-up of the power delivery. The Efficiency program, in turn, upshifts at earlier points not only to significantly reduce fuel consumption under normal driving conditions, but also to allow a relaxed style of driving by taking advantage of the new M engine’s prodigious torque and power available from low engine speeds. The result, therefore, is an ideal combination of flexibility for daily use and all-out performance when desired.

When customizing the response of the steering wheel-mounted M Drive button, the driver uses the M Drive menu to preselect the desired Power Mode and the setup of DSC and EDC, making a personalized combination of settings that can be activated on-demand. The driver’s favorite setup settings are saved and subsequently activated at any time simply by pressing the M Drive button on the steering wheel. Pressing the M Drive button again returns the vehicle to its previous configuration.

M-specific cockpit and sophisticated driver assistance systems for even greater ability at the wheel.

The BMW M philosophy naturally continues into the design and configuration of the driver’s “office.” Both of these all-wheel-drive high-performance sports vehicles come with a special M cockpit with the instrument cluster featuring a variable redline, specific vehicle function displays, and white display backlighting. Both the BMW X5 M and the BMW X6 M feature power, heated front M sport seats, an M sport leather steering wheel, M door sills, and driver’s footrest.

Infotainment functions, standard on-board Navigation with Real-Time Traffic data and communication functions are all controlled by BMW’s 4th-generation iDrive. The standard HiFi audio system features 12 loudspeakers and a 230 watt amplifier. In addition, both the BMW X5 M and the BMW X6 M may be equipped with a Head-Up Display programmed specifically by BMW M. This option enables the driver to customize the type and scope of data projected onto the windshield through settings available in the M Drive menu.

Innovative driver assistance systems are fitted as well, with both models featuring standard Dynamic Cruise Control, Rain Sensor, Auto-Dimming Mirrors, Park Distance Control, and BMW’s Xenon Adaptive Headlights. The list of optional features includes a Driver Assistance Package which includes High-Beam Assistant, Head-Up Display, and Rear View Camera with the spectacular new Top View feature. Top View provides the driver with an “birds-eye view” of the vehicle on the iDrive control screen, using input from a camera on each side of the vehicle and the traditional rear-view camera. Top View provides the driver with additional confidence for tight parking scenarios.

Stable bodyshell and advanced safety equipment.

The BMW X5 M and BMW X6 M come with extremely stiff bodyshells. To ensure maximum solidity, BMW’s body engineers focused on the use of intelligent lightweight materials technology. Both the choice of materials and the arrangement and geometry of the support bars, braces, and mounts on both models are based on an overall concept that combines maximum crash safety with supreme agility - which helps avoid crashes in the first place. At BMW, the ability to avoid a crash is the best safety feature of all.

Forces acting on the unibody in the event of a crash are diverted through the engine carriers and the chassis along several load paths in order to avoid extreme loads acting on individual structures and help keep impact energy away from the stable passenger cell.

Both the BMW X5 M and BMW X6 M come with frontal and hip/thorax airbags, as well as curtain head airbags to protect the occupants both front and rear from injury. Three-point inertia-reel seatbelts are at all seating positions with force limiters and, on the front seats, an additional seatbelt pretensioning function. To help protect occupants from cervical spine injury in the event of a rear impact, the front seats feature crash-activated active head restraints. ISOFIX child seat anchors are standard on the rear seats.

All restraint systems are controlled by the vehicles’ central safety electronics, which take the type and severity of a collision into account so that the most effective safety elements are activated in any given crash. The frontal airbags feature two-stage activation, to allow deployment in varying intensity as a function of crash severity. Networked with Dynamic Stability Control, the standard rollover sensors activate both the curtain airbags and the seatbelt pretensioners, to ensure occupants are best positioned for and protected from the unlikely event of a vehicle rollover.

Design

The BMW X5 M and the BMW X6 M are the first all-wheel-drive cars to offer the features and driving characteristics typical of a BMW M Model – qualities also borne out clearly by the cars’ design. The common DNA also reflected by truly outstanding performance is visibly displayed by the joint design of the front end with strikingly large air intakes on both the BMW X5 M and the BMW X6 M: The engine compartment lid, the front air dam and the headlight graphics carried over from the BMW X6 are identical on both models. A further common feature lies in the twin-tone exterior mirrors again in specific M design. And finally, both the BMW X5 M and the BMW X6 M come with gill elements in the front side panels tailored to each model as well as individually designed 20-inch light-alloy wheels.

Compared with the BMW X5 and the BMW X6, the extent of black plastic surfaces along the lower section of the body is reduced on both models, clearly accentuating the roadgoing orientation of the BMW X5 M and the BMW X6 M to an even higher standard than before. Both models are clearly characterised in particular by those special body elements which fulfil significant functions in terms of aerodynamics and the supply of cooling air.

Over and above these common features, BMW’s two new all-wheel-drive high-performance sports cars stand out as truly unique characters in their own right. The BMW X5 M at very first sight demonstrates all its power and exclusivity, while in its design the BMW X6 M spells out fascinating dynamics and truly athletic charisma.

The rear end of each model also offers a unique interpretation of those typical M features as clear signs of outstanding sportiness. This also applies to the rear air dam finished on both models in body colour and in the styling finish of the wheel arch air outlets again differing from one model to the other. In each case the bumper panel surrounds the two dual tailpipes already well-known as genuine signs of distinction on a BMW M car.

Joint front-end design, individual proportions.

The low contour of the dual headlights “cut off” optically at the top, the upright position of the kidney grille with its bar elements finished in black, and the powerful sculpture of the front air dam painted completely in body colour accentuate the clear orientation to the road of both the BMW X5 M and the BMW X6 M.

At the same time the large air intakes bear clear testimony to the dynamic drive units within the engine compartment, with the shape and size of the openings tailored precisely to the cooling requirements of the M TwinPower Turbo as well as the high-performance brake system. Precisely this is why the two new models, like BMW’s other M Cars, intentionally do not come with foglamps integrated in the front air dam.

The dark honeycomb grid on the air intakes is moved far back into the body of the car, with the grid surrounds extending powerfully to the outside. The three-dimensional effect provided in this way underlines the dynamic and self-confident look of both the BMW X5 M and the BMW X6 M. Strong and muscular bars separate the central from the two outer air intakes. Extending towards the V-shaped arrow on the engine compartment lid and continuing all the way to the numberplate support, these beautifully designed bars emphasise the particular stability of both models in dynamic bends and on fast winding roads. Flaps beneath the side air intakes carried over from motorsport, finally, optimise the aerodynamic balance of both models at high speeds.

BMW X5 M: upright proportions demonstrating superior presence and function.

Notwithstanding its similarities and common features shared with the BMW X6 M, the BMW X5 M is clearly identifiable also from the front. This clear identity is ensured by the car’s unique proportions, the more upright windscreen looking larger than on the BMW X6 M and giving the BMW X5 M even greater presence.

Looking more closely, the beholder will also recognise the low BMW Individual roof railing available as an option only on BMW’s Sports Activity Vehicle. From the side he will gain a clear impression of the proportions of the vehicle bearing testimony to the high level of functionality. Through its upright stature, large window areas and very long roofline, the BMW X5 M is full of presence and visual power.

Interaction of the striking contour line on the level of the door openers and the powerful sill-line creates a subtle wedge shape, precise transitions between convex and concave surfaces also characterising the dynamic look of the vehicle.

This interaction is carried over to the special M-style rear-view mirrors identical in design on both models. The elaborately chiselled mirror housings finished largely in body colour are subdivided horizontally by precise lines, with the lower section finished in black bordering on to a sweeping line at the bottom.

The BMW X5 M comes with uniquely designed front side panels bearing the gill intake unit typical of BMW M together with an integrated side indicator and the M logo. Featured as standard, the 20-inch light-alloy wheels also come in the typical design of BMW M, with widely extending V-spokes.

At the rear the BMW X5 is likewise characterised by powerful horizontal lines giving the entire vehicle a truly superior look and emphasising its greater width. The lower section of the body is formed by the discreetly contoured rear air dam boasting numerous features inspired by motorsport and with horizontal lines additionally emphasising the wide track of the vehicle.

Interior in typical M style

The interior of the BMW X5 M is characterised by generous luxury and the flexible use of space, while the ambience within the BMW X6 M offers a supreme standard of sporting exclusivity. In both cases the equipment and interior design proudly boast that unique style and class so typical of BMW M.

The BMW X5 M offers ample freedom of movement for up to five occupants, with a high standard of motoring comfort also on long distances. Even when using all seats, luggage compartment capacity is a substantial 620 litres or 21.7 cubic feet. And when the driver completely folds down the asymmetrically split rear seat bench, luggage capacity increases to a truly exceptional maximum of 1,750 litres or 61.3 cubic feet.

In the BMW X6 M the rear doors opening up to a wide angle facilitate access to the rear. This unique Sports Activity Coupé comes with single seats also at the rear providing superior side support and featuring integrated headrests. At 570 litres or almost 20.0 cubic feet, the luggage capacity available behind the rear seats exceeds that of a regular coupé by far.

The BMW X6 M comes with a strong, folding luggage compartment cover stowing away very practically beneath the floor of the luggage compartment for transporting bulky objects. To increase transport capacity, the driver and occupants may again fold down the asymmetrically split rear seat backrests, increasing luggage volume to a maximum of 1,450 litres or 50.8 cubic feet. And last but not least, the BMW X6 M comes as standard with an automatic opening and closing function on the tailgate.

Adjusting electrically to a wide range of different positions and featuring individual heating controls, the M seats in both models are finished as standard in BMW Individual Merino leather. The natural grain and soft surface of this high-class leather is particularly elegant and offers an unusually pleasant surface touch.

It almost goes without saying that all the leather used is free of even the slightest blemish or irregularity on the surface, just as it is treated naturally, without any artificial treatment of the surface structure.

The final surface effect is indeed provided by a special pigmentation process ensuring complete penetration of the desired colour in a very preserving and mild application maintaining the soft and supple surface of the leather with its active breathing effect and open-pore structure. Leather upholstery comprising not only the seats, but also the centre console, the armrests, the door panels and door closing handles is available in either Black, Silverstone or Bamboo Beige. The seats feature special M seams in a particularly attractive pattern and the M logo is embossed in the headrests on the front seats.

Full leather upholstery in Merino quality is available as an option, with leather finish also on the back of the seat backrests and the door lining frame, plus the further choice of Cinnamon and Sakhir Orange as additional colours. The BMW X6 M furthermore comes as standard with a BMW Individual instrument panel finished in leather, with the upper section in soft nappa and the lower section in Merino leather.

A wide range of high-class interior trim offers further options in emphasising one’s personal style. As standard the BMW X5 M and the BMW X6 M feature interior trim in brushed Aluminium Shadow, and as an alternative both models are available as an option with BMW M interior trim in Carbon Structure leather finished in Black and genuine wood trim again from BMW Individual. The two colours available in this case are Piano Paint Black and Eucalyptus Bar Reddish Brown.

BMW ConnectedDrive with enhanced emergency call and new remote functions

The BMW Assist telematics service forming part of the BMW ConnectedDrive philosophy with its wide range of individual functions is available for both the BMW X5 M and the BMW X6 M. Apart from personal enquiry services and the latest traffic information, BMW Assist now also includes an enhanced emergency call function with automatic detection of the car’s location.

In the event of a collision reaching a certain level of severity, the system auto-matically delivers data on the car’s current location as well as the vehicle itself, together with further data collected by the car’s sensors providing more details on the type of collision and the occupants’ risk of injury, which all goes to a BMW Call Center. From there this information is transferred immediately to the nearest rescue service.

BMW ConnectedDrive will in future also offer the customer support through the BMW Call Center in cases which so far required a breakdown service. Should the driver forget his key in the closed luggage compartment or if a young occupant in the car has locked the doors from inside, for example, all the customer has to do from now on is call the BMW Call Center. Then, once the customer’s identity has been clearly determined, the Call Center is able to unlock the car through a remote function. Conversely, the BMW Call Center may also lock the car through the same remote function should the driver have forgotten to do so.

Extra comfort, fresh air and audio quality provided by four-zone automatic air conditioning, the glass roof, and the BMW Individual High End audio system.

Both the BMW X5 M and the BMW X6 M come as standard with a HiFi audio system featuring 12 loudspeakers and 230 Watt amplifier output, M door entry strips, an M footrest, BMW Individual roof lining in Anthracite, and a Lights Package.

As an alternative to the two-zone automatic air conditioning featured as standard, the customer also has the choice of four-zone automatic air conditioning providing individually adjustable temperatures at the rear. Further options include active seat ventilation, a panorama glass roof for the BMW X5 M, and an electrically operated glass roof on the BMW X6 M.

The BMW X5 M is also available with a towbar incorporating an electrically swivelling ball head, while the BMW X6 M comes as an option with a towbar using a removable ball head. Maximum towing capacity in each case is three tonnes.

A truly exceptional experience in dynamic sound is provided as an option by the BMW Individual High End audio system tailored exclusively to the respective model. No less than 16 high-performance loudspeakers with neodym magnetic drive and extremely stiff hexacone membranes, a digital nine-channel amplifier with maximum output of 825 Watt and precise frequency switches guarantee inimitable quality of sound.

Yet another feature quite unique in the automobile is Dirac Live technology for processing audio signals, correcting the loudspeaker pulse response whenever necessary for linear sound reproduction and exactly balanced playback within the vehicle. The quality of sound ensured in this way in playing back even the most demanding music will offer not only the driver, but rather all occupants a truly dynamic experience of sound absolutely faithful and true-to-life to the last detail.

Speed-related volume control and speed-related equalising likewise ensure an optimum experience in sound in every situation.

The BMW Individual High End audio system is masterminded by the iDrive Controller. The basic functions of the system, finally, are controlled by the audio switches on the centre console, in the same way as with all other entertainment systems.

The M TwinPower Turbo

With the model portfolio being enlarged through the addition of two all-wheel-drive BMW M Cars, the engine range is likewise being enhanced through spectacular new technology: Both the BMW X5 M and the BMW X6 M come with a truly outstanding power unit ranking right at the top in the current engine range of BMW M GmbH in terms of both output and torque.

In this case the power and dynamism so typical of BMW M is provided by a new and truly unique construction principle, the new M TwinPower Turbo with Twin Scroll Twin Turbo Technology and a common exhaust manifold for both rows of cylinders ensuring extremely spontaneous and direct behaviour, linear build-up of power and an unusually consistent torque curve.

The V8 power unit develops maximum output of 408 kW/555 hp at an engine speed of 6,000 rpm. Peak torque of 680 Newton-metres or 501 lb-ft, in turn, is maintained consistently throughout a wide speed range from 1,500 to 5,750 rpm.

With its displacement of 4,395 cc, the new M TwinPower Turbo delivers its exceptional power through particularly sophisticated turbocharger technology. Indeed, the V8 power unit with Twin Scroll Twin Turbo Technology and an exhaust manifold spanning both rows of cylinders represents the absolute state of the art in turbocharging. No other turbocharged engine offers a comparable combination of spontaneous torque and pulling power, a steadily rising power curve typical of BMW M, and maximum efficiency all in one.

Further outstanding features to be admired on the new M TwinPower Turbo are the special BMW M pistons and camshafts as well as the cooling system almost completely new from the ground up. To optimise the cooling circuit in accordance with the exceptionally high output per litre of the engine, the technology already featured on the V8 power unit in the BMW X6 xDrive50i and the new BMW 750i has been significantly modified and upgraded to an even higher standard. Dropping the water reservoir in the V-section between the two rows of cylinders, for example, the responsible engineers have succeeded in reducing not only the amount of coolant, but also the weight of the system.

Together with other features, a second low-temperature radiator with an additional electrical coolant pump improves the intercooling function on the new M TwinPower Turbo. This optimises the performance of indirect intercooling in particularly dynamic driving cycles. And last but not least, an additional electrical coolant pump with an after-running function serves to cool the bearing mounts on the turbochargers after switching off the engine.

Turbochargers and catalytic converters in the V-section between the two rows of cylinders.

The highly innovative turbocharging system results from both the arrangement of the turbochargers and the supply of air. Together with the catalytic converters, the two turbochargers are positioned in the V-section between the two rows of cylinders at a 90° angle. This special position already to be seen on the eight-cylinder power units featured in the BMW X6 xDrive50i and the new BMW 750i allows unusually compact dimensions and arrangement. At the same time it requires intake and outlet ducts in a new position, reducing the length of the pipes and allowing larger cross-sections significantly minimising pressure losses on the exhaust side.

A further advantage of this arrangement is the shorter distance between the combustion chambers and the primary exhaust gas management systems. As a result, the catalytic converters reach their optimum operating temperature even more quickly after starting the engine.

Perfect guidance of gas flow: the dual-cylinder exhaust gas manifold

Patented by BMW, the common flow of exhaust gas for both rows of cylinders ensures optimum gas throughput under all conditions. BMW’s new M ¬TwinPower Turbo is indeed the first power unit in the world to feature such an unprecedented exhaust manifold.

This particular configuration is made possible by arranging the exhaust gas turbochargers and the catalytic converters in the V-section between the two rows of cylinders. The unique principle of the dual-row exhaust gas manifold thus provides the basis for the exceptionally spontaneous and direct response of the M TwinPower Turbo.
The system features no less than four completely separated exhaust gas pipes to provide this new technology. Two pipes on each side flow into each of the two Twin Scroll Turbochargers, merging together shortly before they reach the turbine. This provides a consistent and intense supply of exhaust gas ensuring a spontaneous and direct response and maintaining consistently high turbocharger pressure.

Functioning independently of the respective row of cylinders, the four exhaust gas ducts are allocated to those two combustion chambers which have a firing interval of 360° ideal for a V8 power unit in the efficient use of exhaust energy. This provides a steady and constant rhythm of gas flow in each of the two exhaust ducts, an effect further enhanced by the identical length of each duct on the exhaust gas manifolds linked to one another. The result is a consistent level of pressure acting on the two turbochargers, without any kind of counter-flow or adverse pressure.

The Twin Scroll Turbochargers specially developed for the new M turbo engine excel through their particularly high level of compressor and turbine efficiency, with the system operating at maximum charge pressure of 1.5 bar.

The Twin Scroll Twin Turbo power unit with its dual-cylinder exhaust gas manifold uses the potential of turbocharger technology in a unique manner. The extremely spontaneous and direct response of the system and the unusually high level of torque and pulling power extending all the way up from low engine speeds and constantly maintained up to a high load level are the characteristic features of the new M TwinPower Turbo. This truly impressive development of power is accompanied by fascinating engine sound highlighting the free-revving characteristics and the linear build-up of power through that typical, thoroughbred sound effect so characteristic of a BMW M Car.

Standing out clearly from the conventional sound of a V8 with its low frequencies, the M TwinPower Turbo develops a completely different and absolutely unique sound pattern with its sporting characteristics borne out in particular by the dual-cylinder exhaust gas manifold.

The introduction of map-controlled exhaust gas flaps in the exhaust system furthermore offers the option to clearly distinguish also in acoustic terms between the various settings in the Power Mode – the Sports and Efficiency driving programs, each standing out through their very distinctive engine sound. The twin-chamber exhaust system on the new M TwinPower Turbo is characterised largely by straight pipes and a large cross-section. The two exhaust pipes merge into a common silencer at the rear leading on to the two dual tailpipes so typical of BMW M with their chrome trim right at the end.

Acceleration in the BMW X5 M and the BMW X6 M is ultra-powerful and dynamic right from the start, with huge thrust from the ground up. Both models reach 100 km/h from a standstill in just 4.7 seconds, continuing to accelerate at a fascinating pace all the way to top speed.

Top speed of both models is limited electronically to 250 km/h or 155 mph. As an option, however, this self-imposed speed limit may be raised to 275 km/h or 171 mph in conjunction with the optional M Driver’s Package. This also includes BMW Driver Training on a race track giving the discerning motorist the final qualifications for such outstanding performance.

Supreme efficiency in the segment thanks to High Precision Injection and BMW EfficientDynamics

The new M TwinPower Turbo develops its outstanding performance not only through supreme power and muscle, but also with a degree of efficiency unparalleled in this segment.
This superiority is attributable largely to the fuel supply system, High Precision Injection with piezo-injectors positioned between the valves ensuring a particularly precise supply of fuel.

¬High Precision Injection uses injectors positioned directly next to the spark plugs in the cylinder head and supplying fuel to the combustion chambers at a pressure of 200 bar. The cooling effect provided through the direct injection of fuel allows a higher compression ratio than on a turbocharged engine with conventional manifold injection. This increases the efficiency of the engine accordingly, providing more power on less fuel.

Another important factor contributing to such greater fuel economy is double-VANOS infinite camshaft adjustment typical of BMW power units. An important advantage of double-VANOS is that it helps to develop high torque at low engine speeds for powerful acceleration from the ground up. Efficiency is enhanced to an even higher level by the volume flow-controlled oil pump, with the oil level being measured by sensors showing the data recorded whenever required in the instrument cluster.

Greater innovation for greater efficiency: volume flow-controlled supply of hydraulic fluid for anti-roll stability

In addition to all the features mentioned, both the BMW X5 M and the BMW X6 M come with a wide range of BMW EfficientDynamics technologies all offered as standard. Brake Energy Regeneration, for example, concentrates the generation of electric current for the on-board network on the car running in overrun and during application of the brakes. This concept of intelligent energy management within the car restricts the conversion of primary energy into electricity to exceptional cases and conditions, with more engine power being provided for extra driving dynamics.

The use of an on-demand electric fuel pump, to mention another example, serves to further reduce the uptake of energy, with the power required by the pressure-controlled pump being reduced by more than 50 per cent under driving conditions in which the engine requires only a small amount of fuel. And last but not least, detachment of the a/c compressor from the belt drive also serves to enhance the vehicles’ efficiency, reducing drag forces from the engine as long as the air conditioning is switched off.

Volume flow-controlled supply of hydraulic fluid exactly as required on the BMW X5 M and the BMW X6 M is a new development serving to enhance the efficiency of the anti-roll stability system featured as standard. An additional valve in the hydraulic pump of the anti-roll stability unit supplies the delivery pistons with exactly the right amount of hydraulic fluid at any given point in time, reducing the uptake of power by the pump by up to 70 per cent when driving straight ahead at a steady speed. And thanks to the precise control technology, the hydraulic pressure required under specific conditions is always provided in good time.

Thanks to the high efficiency of the engine and the wide range of technologies serving to reduce fuel consumption, the BMW X5 M and the BMW X6 M offer not only the highest standard of driving dynamics in the segment of extra-powerful all-wheel-drive cars, but by far also the highest level of efficiency: Both models average fuel consumption in the EU test cycle of just 13.9 litres/100 kilometres, equal to 20.3 mpg imp. Their CO2 rating, in turn, is 325 grams per kilometre.
BMW High Precision Injection also has a positive impact on both emissions and the sound of the engine, both models fulfilling the US LEV II emission standard as well as the EU5 classification in Europe.

M Sports Automatic with electronic gear selector lever and shift paddles on the steering wheel

Featured for the first time on a BMW M Model, six-speed automatic transmission enhances the high-performance character of the BMW X5 M and the BMW X6 M through the spontaneous gearshift, a direct connection to the engine, and the high standard of gearshift comfort. To achieve extremely short gearshift times the system incorporates an innovative torque-reducing function in the manual mode, switching off individual cylinders by cancelling out the fuel injection and ignition. This allows an extremely fast gearshift and at the same time confirms the particularly sporting character of both models.

BMW’s new M Sports Automatic also incorporates integrated two-damper systems serving to minimise the degree of slip on the converter clutch. Compared with a conventional automatic transmission, the modern torsion damper technology also serves to significantly reduce fuel consumption. To optimise the cooling effect, in turn, the surface of the oil sump made of aluminium again in typical M style comes in a fine ribbed structure.

The new M Sports Automatic is controlled by an electronic gear selector lever on the centre console. Gearshift paddles on the steering wheel made of strong aluminium and again in special M design allow the driver in addition to shift gears manually. In the constellation typical of an M Car, the driver merely pulls the right gearshift paddle to shift up and the left gearshift paddle to shift down.

Apart from the D Mode, the driver also has the choice of the S and M Mode, each offering an even more sporting gearshift set-up. In the M Mode the gear in mesh is kept in position up to maximum engine speed, giving the driver optimum control of the vehicle even under the most dynamic driving conditions. Hence, the transmission does not shift up automatically in this mode.

Moving one of the paddles, the driver is able to shift gears manually at any time in a most spontaneous process. As soon as he does so, the transmission immediately leaves the automatic program and changes automatically to the manual mode. If the driver does not use the paddles again after making such a change, the transmission will move back by itself to the automatic mode after a certain period.

In the M Mode the driver is also able to activate the Launch Control function for maximum acceleration from a standstill. To activate Launch Control, all the driver has to do with the car at a standstill is move the gear selector lever into the M/S lane and call up the Sports Power Mode as well as the M Dynamic Mode or, respectively, the DSC-Off function.

With the transmission in stage M1, the driver then presses down the brake pedal and moves down the gas pedal at least 60 per cent of its full travel in order to set Launch Control to standby. This status is presented by a starter flag symbol in the instrument cluster. As soon as the driver lets go of the brake pedal, the car will accelerate with full power in genuine racing style. In the process M Sports Automatic automatically shifts gears at the ideal point, with the fastest possible shift times and optimum slip control. Then, taking back the gas pedal, the driver is able to terminate the Launch Control process whenever he wishes.

BMW xDrive

The outstanding success of BMW’s intelligent xDrive all-wheel-drive technology is based on the fact that this sophisticated system conveys traction in a unique manner not only on rough terrain, but also on hard road surfaces, offering outstanding driving dynamics in the process. Electronically controlled, variable power distribution front-to-rear interrupts even the slightest tendency to over- or understeer at the earliest conceivable point, before DSC Dynamic Stability Control is required to cut in. BMW xDrive also stands out as an intelligent all-wheel-drive system by guiding drive power through a distributor transmission with an electronically controlled multiple-plate clutch in an exact dosage precisely to the right axle where the wheels have the best grip on the road.

To ensure this superior traction sensors constantly measure wheel slip both front and rear. Within fractions of a second, the system is able to vary the distribution of drive power, BMW xDrive, unlike conventional all-wheel-drive systems, looking ahead and acting in advance, without waiting until a wheel starts to spin. This stabilises the vehicle before any slip is able to build up and the driver feels the need to act.

Both the BMW X5 M and the BMW X6 M feature a special xDrive set-up

developed specifically for these two vehicles in the interest of greater drive power at the rear, offering significant benefits under highly dynamic driving conditions and thus fulfilling the demands made of a typical M Car.

Dynamic Performance Control enhancing the driving behaviour typical of BMW M: precise steering response and dynamic acceleration out of bends and on winding roads.

The combination of BMW xDrive optimising traction and pulling force in terms of both stability and driving dynamics, on the one hand, and Dynamic Performance Control in the BMW X5 M and the BMW X6 M, on the other, provides an even higher standard of excellence than before, with the distribution of power being further differentiated between the right-hand and left-hand rear wheel.

Variable distribution of drive power between the rear wheels significantly enhances both steering precision and tracking stability at all speeds, the car following the steering with a much higher degree of precision right from the start even at moderate speed. Dynamic Performance Control then adds further supremacy in highly dynamic steering manoeuvres.

BMW xDrive and Dynamic Performance Control interact most efficiently also in maintaining the vehicle’s driving stability on slippery surfaces. As soon as the vehicle starts to understeer, xDrive reduces the flow of power to the rear wheels “pushing” to the outside and Dynamic Performance Control cuts back drive forces on the outer rear wheel in a bend subject to particularly high centrifugal loads, diverting that drive power to the inner rear wheel.

Possible understeer is prevented in exactly the opposite manner, xDrive

reducing the flow of power to the front wheels “pushing” to the outside, Dynamic Performance Control shifting drive power to the outer rear wheel for optimum stability. As a result, the vehicle enters a bend even more precisely, following the course taken by the driver with greater agility and tracking stability, regardless of road speed.

The difference in drive power acting on the two rear wheels established by Dynamic Performance Control may be anything up to 1,800 Newton-metres. For the driver this means a significant improvement of agility, traction, and driving stability. He also recognises the effect of Dynamic Performance Control by the significant reduction of DSC Dynamic Stability Control cutting in. This enables the driver to use the power of the engine in full longer than before, with DSC slowing down individual wheels or reducing engine power only when driving to the physical limit.

Dynamic Performance Control also develops its stabilising effect as soon as the driver takes his foot off the gas pedal in a bend. Within the final drive an additional superimposed gear unit made up of a double planetary gearing and a multiple-plate brake operated by an electric motor maintains the variable distribution of drive power also in overrun.

In its specific BMW M set-up, Dynamic Performance Control serves furthermore to give the vehicle most dynamic acceleration qualities at the end of a bend: Under high load the distribution of drive forces seeks to convey lateral forces to the highest possible degree, giving the vehicle the highest conceivable level of acceleration.
Looking at the Control Display, the driver is able to monitor the activity of Dynamic Performance Control and xDrive also through a clear visual message. A graphic display available in the vehicle function menu provides clear information on the current distribution of drive forces, a symbolic presentation of the four drive wheels using arrows to show the driver how much power is being spread out to each wheel.

M Dynamic Mode for maximum speed in bends.

Both the BMW X5 M and the BMW X6 M use the potential of both systems in specific M style. Pressing the DSC button on the centre console, the driver is able to activate the M Dynamic Mode (MDM) as an alternative to the basic setting. This special mode raises the DSC control thresholds for intervention by the brakes and the reduction of engine power and, setting up a special xDrive function with more power on the rear wheels while interacting with Dynamic Performance Control, provides the steering behaviour again typical of BMW M.

As a result MDM allows maximum speeds in bends with the control systems intentionally cutting in very late, close to the physical limit. Even under the highest conceivable loads at the apex of a bend, therefore, the vehicle follows the steering and the driver’s commands with absolute precision. And last but certainly not least, the driver is also able to activate the DSC-Off Mode at the touch of a button.

Over and above the stabilising effect provided by intervention in the brakes and the reduction of engine power, DSC in the BMW X5 M and the BMW X6 M comes with a wide range of additional functions promoting both safe and dynamic motoring. These include features such as ABS anti-lock brakes, ASC Automatic Stability Control, Trailer Stability Control, HDC Hill Descent Control, DBC Dynamic Brake Control automatically maximising brake power whenever required, CBC Cornering Brake Control, and Cruise Control with its own brake function.

The electronic Automatic Differential Brake (ADB-X) serves additionally to provide a differential function automatically applying the brakes on a wheel about to spin and thus enabling the opposite wheel on the same axle to keep on running under the same power and with the same drive force.

Anti-fading is ensured when driving under dynamic conditions and with the brakes at extremely high temperatures by increasing brake pressure to maintain the same stopping power as before. Regular Dry Braking, in turn, optimises the performance of the brakes in the wet. And last but not least the Start-Off Assistant makes it much easier for the driver to set off on an uphill gradient, without the vehicle rolling back.

Both the BMW X5 M and the BMW X6 M come with a parking brake combining electromechanical and hydraulic operation. The parking brake is activated or released by means of a separate button and comes with an Autohold function holding the vehicle in position as soon as it comes to a standstill at a road junction or in stop-and-go traffic, without requiring the driver to press down the brake pedal. Then, as soon as the driver starts out again, the brake is automatically released.

Special M suspension with newly developed Servotronic steering and Adaptive Drive featured as standard

The suspension developed especially for the BMW X5 M and the BMW X6 M with its double-track control arm front axle and Integral-IV rear axle comes with special M elastokinematics provided by stiffer track control mounts and tiebar hydraulic bearings at the front as well as stiffer axle subframe mounts at the rear. Both models come as standard with air suspension featuring self-levelling on the rear axle, newly developed Servotronic steering as well as Adaptive Drive with electronically adjustable dampers (EDC) and active anti-roll stabilisation.

The Servotronic steering developed specifically for the BMW X5 M and the BMW X6 M provides appropriate steering assistance geared to the actual speed of the car. This ensures comfortable parking with steering forces reduced to a minimum as well as exact feedback and a high level of steering precision at higher speeds. The degree of steering assistance is defined by two control maps: Apart from the standard configuration, the driver is able, pressing the EDC or, respectively, the M Drive button in the Sports Mode, to activate an uncompromisingly dynamic control map with higher operating forces for very dynamic and sporting driving conditions. This ensures particularly clear feedback from the steering to the driver for superior and sports motoring at all times.

The M set-up of Adaptive Drive also lowers the entire vehicle by 10 millimetres or 0.39" compared with the “regular” BMW X5 and BMW X6, further features being stiffer carrier springs, modified auxiliary springs, a three-way support mounting, and damper configuration with improved connection to the body. All this adds up to provide maximum driving dynamics, motoring comfort and safety at all times. Side sway and body movement are reduced, steering behaviour and the load change response are optimised.

Through its sensors, Adaptive Drive permanently monitors and calculates data on road speed, steering angles, longitudinal and lateral acceleration, body and wheel acceleration, as well as ride levels. Using this information, Adaptive Drive controls and masterminds both the swivel motors in the anti-roll bars as well as the electromagnetic valves on the dampers, thus regulating side sway and the damping effect at all times according to current conditions.

To quickly and reliably process data, Adaptive Drive uses the high-speed FlexRay data transmission system. BMW is indeed the first carmaker in the world to use FlexRay in its cars as a regular technology.

Pressing the EDC button, the driver is able to vary not only the Servotronic control map, but also the set-up of the dampers. Compared with the Normal Mode, this change in set-up reinforces the connection between the dampers and the body in the Sports Mode. Interacting with anti-roll stability, this then provides a very linear build-up of lateral forces in dynamic bends, keeping the driver in superior control all the way to the absolute limit in driving physics.

Intelligent management of driving dynamics: Integrated Chassis Management

The drive and suspension systems are perfectly orchestrated in their joint network by ICM Integrated Chassis Management. This highly efficient electronic control system coordinates the drivetrain and suspension functions of the BMW X5 M and the BMW X6 M within fractions of a second, ensuring maximum stability and supreme performance at all times and in every situation.

Even under suddenly changing conditions – for example on changing surfaces, with the driver spontaneously turning the steering, when accelerating or applying the brakes abruptly – Integrated Chassis Management responds by controlling the xDrive, DSC, Dynamic Performance Control, Servotronic, and Adaptive Drive actuators with supreme precision. The type and extent of such intervention is consistently masterminded to ensure not only maximum driving stability, but also optimum dynamics at all times.

Powerful, reliable, and light: high-performance brake system

Outstanding stopping power with fading reduced to an absolute minimum is guaranteed by the high-performance brake system combining four-piston fixed-calliper brakes at the front and swing-calliper brakes at the rear with inner-vented lightweight b rake discs.

The brake discs themselves measuring 395 mm/15.55" in diameter at the front and 385 mm/15.16" at the rear feature a riveted connection joining the aluminium brake holder and the grey-cast-iron friction ring to effectively counteract any heat-induced deformation even under maximum loads.

The BMW X5 M and BMW X6 M are the only vehicles in their segments fitted as standard with different-sized tyres geared specifically to each model and running on 20-inch light-alloy rims all round. The choice of 275/40 R 20 tyres up front and 315/35 R 20 tyres at the rear is yet another result of the set-up of the two vehicles giving greater emphasis to extra power on the rear wheels.

With this ideal combination of tyre sizes in the interest of driving dynamics, both models optimise the transmission of power to the rear wheels as well as the precise and exactly controllable steering behaviour ensured in each case.

Bodyshell and safety equipment

Like the BMW X6 M, the BMW X5 M comes with an extremely stiff bodyshell. To ensure maximum solidity on minimum weight, BMW’s body engineers focused consistently in the development process on intelligent lightweight technology. Both the choice of materials as well as the arrangement and geometry of the support bars, braces and mounts on both models are based on an overall concept combining maximum crash safety with supreme agility in both models.

Forces acting on the body in the event of an accident are diverted through the engine carriers and the chassis along several load paths in order to avoid extreme loads acting on individual structures and keep impact energy away from the stable passenger cell.

Both the BMW X5 M and the BMW X6 M come as standard not only with frontal and hip/thorax airbags, but also with curtain head airbags at the side inflating out of the A-pillar and roof lining cover to protect the occupants both front and rear from injury. Three-point inertia-reel belts come on all seats, with belt force limiters and, on the front seats, an additional belt tightening function.

To protect the occupants from cervical spine injury in the event of an impact from the rear, the front seats feature crash-activated headrests again as standard. ISOFIX child seat fastenings are likewise standard on the rear seats. All the restraint systems are masterminded by the vehicle’s central safety electronics taking the type and severity of a collision into account and activating the most effective safety elements in each case. The frontal airbags feature gas generators operating in two stages, allowing individual activation of the airbags in varying intensity as a function of accident severity.

In the event of an upcoming rollover, the rollover sensors activate both the curtain airbags and the belt latch tensioners. Networked with DSC Dynamic Stability Control, these sensors guarantee that the system will operate quickly and according to specific requirements. To avoid bumper-to-bumper accidents from the rear, finally, both models come with Adaptive Brake Lights providing an even better warning to drivers following from behind.

As yet a further feature, both models come as standard with runflat tyres enabling the driver to continue to the nearest workshop even with a complete loss of air pressure in the tyres. In addition, the Tyre Defect Indicator will inform the driver in good time of a gradual loss of air pressure.

Optimum visibility: bi-xenon headlights featured as standard

Featured as standard, the bi-xenon dual headlights on the BMW X5 M and the BMW X6 M provide not only optimum illumination of the road ahead, but also, through their corona rings, ensure a very practical, safe and reliable daytime driving light function typical of BMW. Both models come as standard with a lights sensor automatically activating the low-beam headlights as a function of ambient brightness. Two other features also fitted as standard are a rain sensor registering the intensity of precipitation and automatically adjusting screenwiper operation as well as a solar sensor providing information on the degree of sunshine in order to control the automatic air conditioning with utmost precision.

M-specific cockpit and sophisticated driver assistance systems for greater supremacy at the wheel

The typical style of BMW M also comes out clearly in the design and configuration of the driver’s cockpit. Both of these new all-wheel-drive high-performance sports cars boast a special BMW M cockpit featuring a variable pre-warning field in the rev counter, an oil temperature gauge, specific vehicle function displays and white display illumination all in the instrument cluster.

Both the BMW X5 M and the BMW X6 M come as standard with M seats and an M leather steering wheel as well as knee pads in the centre console offering the driver and front passenger additional stability under highly dynamic driving conditions.

Innovative driver assistance systems also promote the experience of supreme motoring. As an example, both models feature cruise control with a brake function as standard, acting on engine management, the selection of gears and the brakes in order to maintain the speed pre-set by the driver. The system permanently registers the vehicle’s lateral acceleration and reduces the road speed of the car whenever necessary in order to prevent any loss of comfort in bends and on winding roads. And last but not least, cruise control with automatic application of the brakes also provides assistance in driving downhill in a controlled mode – even when towing a trailer – by intervening in the brakes wherever necessary.

Adaptive Headlights and a High-Beam Assistant are available as an option, together with other helpful features and technologies. And to supplement Park Distance Control featured as standard, the customer may also choose a back-up camera with a Top View function.

Dynamic performance at your fingertips: M Drive button on the steering wheel

Both the BMW X5 M and the BMW X6 M come with drivetrain and suspension technology offering outstanding supremacy at all times together with unparalleled performance whenever required. Choosing the DSC mode as well as the appropriate damper and steering set-up at the touch of a button, the driver is able to opt for either a most dynamic or a more comfortable suspension set-up, as he wishes. Similarly, the driver is also able to configure the drivetrain set-up of the BMW X5 M and the BMW X6 M individually according to his or her personal requirements: Opting for the Power mode acting on both the engine and transmission set-up, the driver has the choice of both the Sports and Efficiency driving programs whenever required.

The Sports driving program allows precise dosage of engine power specifically through the linear increase in output, providing the highly dynamic performance so typical of an M Car. The Efficiency program, in turn, shifts up gears at an early point not only to significantly reduce fuel consumption, but also to allow a relaxed style of motoring using all the engine torque and power available from low engine speeds. The combination provided in this case, therefore, brings together superior efficiency with a high standard of supremacy at the wheel.

In the M Drive menu the driver is able to pre-configure both the Power mode as well as the DSC and EDC set-up. The combination of set-ups chosen thus provides the overall balance of the vehicle preferred by the driver in each case. This combination may be saved conveniently and then retrieved at any time simply by pressing the M Drive button on the steering wheel. So pressing the button just once enables the driver to activate the ideal overall set-up whenever appropriate.
The M Drive menu is the specific M feature supplementing the iDrive control system already masterminding a whole range of vehicle, infotainment, navigation, air conditioning, and communication functions.

Both the BMW X5 M and the BMW X6 M come with the new generation of BMW iDrive. The ergonomically optimised Controller, the direct selection buttons surrounding the Controller, the favourite buttons beneath the radio control panel, and the 8.8-inch Control Display with its high-resolution graphic presentation allow intuitive selection and activation of functions with the driver hardly taking his eyes off the road.

An M-specific Head-Up Display is also available as an option, projecting important information directly into the driver’s field of vision on the windscreen. The type and scope of data presented may also be determined via the M Drive menu, with the driver simply pressing the M Drive button to obtain his or her special M-style presentation. In this case the Head-Up Display highlights the variable pre-warning field in the rev counter and, through its Shift Light function, specifies the optimum point for shifting gears. At the same time the display informs the driver of the gear currently in mesh and the current speed of the vehicle.

Use of the optional Professional navigation system is further simplified by the optimised technical features of BMW iDrive. Full-screen presentation of maps, for example, offers a very detailed overview of the region through which the driver is currently travelling. As an alternative the driver is able to activate an assistance window in the Control Display presenting further details independently of the main map. When approaching a road junction, to mention another example, the system activates a High Guiding function supporting the driver with clear graphic signals in selecting the appropriate lane on the road.

With navigation data being saved on an 80 GB hard disc installed in the vehicle, access times are even shorter than before. And as a further advantage the data system may also be used as a 15 GB music archive.

"But drag strip performance only accounts for a fraction of why the X5 M is so remarkable. BMW has developed a new power-steering system for the X5 M with variable mapping that adapts effectively to both sporting occasions and parking lots. Unlike typical heavy-effort BMW steering (which appears to be on the road to extinction), the X5 M delivers unfettered feel and precision without syrupy heft and resistance." (InsideLin
