BMW X6 EfficientDynamics

The BMW X6 is aimed at the enthusiastic driver and, courtesy of BMW’s EfficientDynamics technology, its all round performance is enhanced by a number of intelligent features.

Brake Energy Regeneration, incorporating an Intelligent Alternator Control and an Absorbent Glass Mat battery to recycle previously lost energy, ensures unrivalled fuel consumption in the X6. This is achieved as the alternator reduces drag on the engine by only engaging when required to charge the battery. Normally a traditional alternator is constantly draining power from the engine. Additionally, the energy generated by the engine on over-run (under braking or descending a hill) was also previously wasted. Now this lost energy is used by the alternator to charge the battery.

Reduced rolling resistance tyres featuring special heat resistant, anti-distortion materials in the tread and sidewalls lower emissions and improve fuel efficiency on the X6. The Sports Activity Coupé comes with low friction transmission fluids for efficient running and active aerodynamics to regulate air flow to the engine. This enables the engine to always work at its optimum efficiency for the benefit of power and economy. Petrol-powered X6s also feature high-precision direct injection for the optimum in combustion characteristics.

BMW X6 Dynamic Performance Control

Twinned with BMW’s benchmark xDrive four-wheel drive system, Dynamic Performance Control makes its world debut on the BMW X6. Dynamic Performance Control works by spreading drive forces from side to side at the two rear wheels as required in a given situation.

Dynamic Performance Control is unique. It is the only system of its kind in the world able to provide its stabilising effect both under power and with the engine on overrun.  The system works by detecting possible over- or understeer of the vehicle in, for example, a bend. When this occurs Dynamic Performance Control will vary the distribution of drive forces between the wheels for perfect stability, dynamic traction, and forward motion. This is achieved by transferring additional wheel speed to the outer rear wheel to push the car round the corner rather than applying brake force to the inner wheels as currently happens with traditional stability control systems.

In the process, Dynamic Performance Control improves driving stability at all speeds, not only ensuring maximum traction when pulling away and precise control when entering a bend, but also higher levels of lateral acceleration and optimum directional stability when accelerating out of the bend.
