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. 4.4 L V8 turbo (hybrid petrol ActiveHybrid X6)ħ-speed Two-mode Active ECVT (ActiveHybrid X6)Į71 development began in 2003 under Peter Tuennermann, after start of E70 X5 development in 2001.While slightly longer and wider than the X5, it is significantly lower and seated initially only four, and since 2011, optionally five. The concept model debuted at the 2007 Frankfurt Auto Show and the production X6 officially debuted at the 2008 North American International Auto Show in Detroit and Montreal International Auto Show. The third-generation X6 was revealed in July 2019. The first generation (E71) was released for sale in April 2008 for the 2008 model year, while the second-generation X6 (F16) was launched at the Paris Motor Show in 2014. Prior to the release of the X7, the X6 was considered a flagship SUV for BMW. It is built in BMW's North American plant in Greer, South Carolina alongside the BMW X5, whose platform it shares. It combines the attributes of an SUV (high ground clearance, all-wheel drive and all-weather ability, large wheels and tires) with the stance of a coupé (styling featuring a sloping roof). The BMW X6 is the originator of the sports activity coupé (SAC), referencing its sloping rear roof design. The BMW X6 is a mid-size luxury crossover SUV by German automaker BMW.
