BMW xDrive is the marketing name for the all-wheel drive system found on various BMW models since 2003. The system uses an electronically actuated clutch-pack differential to vary the torque between the front and rear axles. Models with the DPC torque vectoring system also have a planetary gearset to overdrive an axle or rear wheel as required.

40-597: A 6-speed manual transmission was also available in the United States. The M6 coupé has a carbon fibre roof in order to reduce weight and for a lower centre of gravity. Additional features included: sports seats, larger front and rear brakes, an M-performance instrument cluster, a carbon-fibre roof (coupé only), and an optional M head-up Display. The car also has quad exhaust-pipes and larger, more aerodynamic air intakes. A total of 9,087 coupés and 5,065 convertibles were built; amounting to 14,152 cars. In September 2007,
60-881: A non-conventional convertible top design with side fins and an integrated wind deflector that can be raised or lowered at any time. Top speed for all models is electronically limited to 250 km/h (155 mph). The available transmissions are: Unlike the related E60 5 Series , the E63/E64 was not available with all-wheel drive ( xDrive ). Features available included adaptive headlights , parking sensors (Park Distance Control), voice control , variable rate steering (Active Steering), active anti-roll bars (Active Roll Stabilisation), radar cruise control (Active Cruise Control with Stop and Go), head-up display , lane departure warning , night vision , keyless entry and starting (Comfort Access), heated steering wheel, universal remote control, and soft-close doors.

The E63/E64 generation was produced by BMW from 2003 to 2010 and is often collectively referred to as the E63. The E63 uses a shortened version of
100-448: Is the transfer case used in nearly all BMW xDrive systems. A different system is used on BMWs which are based on a transverse engine front-wheel drive platform, such as the BMW X1 (F48) , BMW 1 Series (F40) and BMW 2 Series Active Tourer . These models use a GKN Driveline system which sends 100% of the torque to the front wheels by default, only sending torque to the rear wheels when
120-566: The BMW 6 Series (F06/F12/F13) began production as the successor to the E63. The exterior was designed by Adrian van Hooydonk , based on the 1999 BMW Z9 concept car designed by the then BMW Design Chief Chris Bangle . The controversial rear styling, first seen on the E65 7 Series , was nicknamed "Bangle Butt" by critics. BMW described the styling philosophy as "flame surfacing", where concave and convex shapes meet to create sharp edges. To reduce weight,
140-554: The E60 5 Series chassis and subsequently shares many features. The car initially drew criticism, due to its controversial styling and complicated iDrive system. The M6 model was introduced in 2005 in coupé and convertible body styles. It is powered by the S85 V10 engine shared with the E60 M5 , and most M6s were produced with a 7-speed automated manual transmission ("SMG III"). In March 2011,
160-507: The facelift (LCI) was introduced for the 2008 model year . Major changes include: Models feature BMW's Advanced Safety System, enabling the car to decide the most effective deployment of the airbags in a crash. Safety equipment includes active anti-roll bars , dynamic stability control , front knee airbags (in accordance with US regulation), BMW roadside assistance , and an SOS emergency system. Convertible models also feature an automatic rollover protection system, where roll-bars behind
180-434: The doors and bonnet are made of aluminium, and the boot and front wings are made of carbon-reinforced plastic . The kerb weight is 1,490–1,930 kg (3,280–4,250 lb). Coupé models were unveiled at the 2003 Frankfurt Auto Show , and introduced on the market in middle of the 2003 model year. Convertible models were unveiled at the 2004 Detroit Auto Show , and released in mid 2004. Convertible models featured
200-575: The front wheels are slipping. An upgraded version of xDrive with torque vectoring , called 'Dynamic Performance Control' (DPC), was introduced on the 2008 BMW X6 and has since become available on other vehicles including the BMW X5 M . As per most torque vectoring systems, the primary function is to increase agility in cornering. The DPC system is also used by the electronic stability control (DSC) to correct for understeer/oversteer, with one reviewer commenting that it provided smoother results and avoided
220-419: The newly released BMW X3 (E83) - ATC400 Transfer Case , facelifted BMW X5 (E53) - ATC500 Transfer Case . In the following years, the availability of xDrive increased throughout the model range, and it is currently available on most models. The first BMW M models to use xDrive were the 2009 E70 X5M and E71 X6M models. The first non-SUV BMW M model to not be rear-wheel drive was the 2017 F90 M5 , which

#1732898703839240-443: The planetary gear. Up to 80% of the torque can be transferred to the tripping axle, using the increasing shear force of the silicone fluid in the viscous coupling (due to the slotted/grooved plates inside the unit) as wheel slip causes one axle to spin faster than the other. The same principle applies to the rear differential varying the torque split between the rear wheels. The front differential has no locking function. All-wheel drive
260-408: The rear drive shaft is hard-coupled to the transmission output. The wet clutch is applied through a high speed electric servo motor turning a cam-shaped actuator disc. In most vehicles, the system uses open differentials at the front and rear, relying on the brakes (controlled by the electronic stability control system) to transfer torque away from the slipping wheel on each axle. The Magna Actimax
280-471: The rear seats are automatically deployed in a rollover. From 2008, active head restraints became a standard feature on all seat options, reducing the risk of neck injuries in a rear-end collision . The E63/E64 was produced at the Dingolfing BMW plant . The following are production figures for the E63/E64, excluding M6 models: BMW xDrive Prior to the introduction of xDrive, all-wheel drive

320-476: The temporary power loss associated with the traditional method of using individual wheel brakes in such situations. The DPC system can distribute torque between the front and rear axles, and between the two wheels on the rear axle. The system uses a clutch pack and planetary gearset within the differential to overdrive a wheel or axle as required. The first xDrive models (as opposed to the earlier all-wheel drive system) were released in 2003. These consisted of
340-443: The wheels with traction. Unlike its predecessor, the xDrive system uses an electronically actuated clutch-pack differential that engages to send torque to the front axle. In the case of the 2018 X3 through X6 models, the default torque split is 40:60 and the system is able to send 100% of the torque to either axle. However, full torque transfer to the front axle can only be achieved if the rear wheels have absolutely no traction, as
360-413: Was available on several models since 1985, based on an all-wheel drive system that uses viscous couplings. The first BMWs available with all-wheel drive were the 1985-1992 E30 325iX and 1991-1996 E34 525iX models. These cars use centre and rear differentials with viscous couplings to vary the torque split between wheels. The centre differential has a default front:rear torque split of 37:63, due to
380-574: Was discontinued when the E30 3 Series and E34 5 Series were replaced by the E36 and E39 respectively. All-wheel drive was reintroduced in 2001 for the X5 SUV and E46 3 series 325xi, 330xi and 330xd sedans/wagons. The system is similar to the earlier version, except without the viscous couplings. Instead, the electronic stability control (DSC) system applies the brake to wheels that are slipping, helping transfer power to
400-584: Was initially introduced as a coupé at the 2005 Geneva International Motor Show , and later in convertible form at the British International Motor Show in 2006. The M6 is powered by the 5.0-litre naturally aspirated S85 V10 shared with the E60 M5, generating 373 kW (500 hp) at 7,750 rpm and 520 N⋅m (384 lb⋅ft) at 6,100 rpm. The majority of the cars were produced with a 7-speed automated manual transmission ("SMG III"), however
