11/24/2023 0 Comments Bmw crossover blackM Performance Parts were available for the X6 M. Other features include 6-speed M Sports automatic transmission with aluminum pull-style paddles on the steering wheel, M Dynamic Mode feature, 10 mm (0.4 in) lower Adaptive Drive suspension, 4-piston fixed calipers with 15.6" rotor at front and single piston floating calipers with 15.2" rotor at rear, 20-inch alloy wheels with 275/40R20 front and 315/35R20 run flat tires, hill descent control, dynamic stability control, special gills in the front fenders, 20-inch light-alloy wheels. The high-performance M derivative features a twin scroll twin turbo version of the 4.4-litre V8 BMW S63 engine with the Cylinder-bank Comprehensive Manifold (CCM). The X6 M was unveiled at the 2009 New York Auto Show and first went on sale in September 2009. The BMW X6 M and X5 M are the first vehicles from BMW M GmbH to have xDrive all-wheel-drive system and automatic transmissions, and are also crossovers as opposed to passenger cars. ![]() In April 2009, the X6 M version was announced, with a 408 kW (547 hp) version of the BMW S63 4.4-litre twin-turbo V8 engine. In an oversteer situation, the inner wheel is overdriven to regain traction balance. For example while turning, the outer wheel is overdriven to provide greater acceleration using the traction advantage through the dynamic loading of the outboard wheel in cornering. The DPC system speeds up the slower moving wheel (the one with the most traction) in order to maintain stability when needed. This leads to increased brake wear and slower than optimal progress. A conventional control system will use the brakes to reduce the speed of the faster moving wheel (which is the one with less traction) and reduce engine power. The clutch pack activates a planetary gearset which causes one wheel to be overdriven. The DPC differential features clutch packs on both output sides that are actuated by an electric motor. This lateral distribution of torque is commonly known as torque vectoring. Torque is distributed not only between the front and rear wheels (xDrive) but also from side to side at the rear, for improved agility and added stability (through the DPC rear axle). DPC is a drivetrain and chassis control system that works to regulate traction and especially correct over- and understeer by actively spreading out drive forces across the rear axle. The X6 marks BMW's first use of its new Dynamic Performance Control system, which works in unison with xDrive all-wheel drive, both being standard on the X6. Design work by E70 X5 designer Pierre Leclercq was frozen in 2005, with test mules being run from the summer of 2005 and prototypes being tested from late 2006.
