BMW X6, first BMW equipped with torque vectoring differential
BMW X6
BMW will introduce a new segment with the debut of its all-new X6 Sports Activity Coupe at the 2008 Detroit Auto Show in January. The all-new vehicle redefines the very notion of a coupe -- with five doors, a higher ride and loads of cargo space. It defies coupe conventions in one jaw-dropping look, combining coupe agility and SAV versatility, taking the coupe to a higher level.
Featured for the first time as standard in a BMW model, Dynamic Performance Control (DPC) ensures variable distribution of drive forces between the two rear wheels. Developed by ZF, DPC incorporates an rear differential incorporating two planetary gearsets and two clutch packs that enables the system to multiply torque on an individual rear wheel (torque vectoring effect). The result is that DPC can help steer the vehicle by directing torque to either of the rear wheels. Unique the world over, this cutting-edge technology is effective whether the driver is accelerating or decelerating and significantly enhances steering precision and, as a result, the agility of the vehicle at any speed. In fast corners with abrupt steering manoeuvres or with the driver suddenly releasing the gas pedal, DPC serves to improve the stability of the entire vehicle, thus allowing the driver to safely enter and enjoy new dimensions of driving dynamics. Finally, on slippery or uneven surfaces, it provides the further advantage of even safer and more stable traction.
A new V8 engine with Twin Turbo technology and direct gasoline injection is likewise making its world debut in the BMW X6. Displacing 4.4 liters, this eight-cylinder delivers 300 kW (400 hp). It is the first eight-cylinder gasoline engine in the world to feature its turbocharger in the V-section between the two rows of cylinders.
