EfficientDynamics

The launch of the new BMW 7-Series completes the line-up of the entire BMW range now being equipped with EfficientDynamics technologies fitted as standard. With its roof, doors, bonnet and side panels all made from aluminium to dovetail with the principle of lightweight engineering, the BMW 7-Series also has other innovative class-leading technology which improves engine performance, while cutting fuel consumption and emissions.

Brake Energy Regeneration uses the engine's power on overrun, such as braking, to charge the battery for the car's electrical circuit. When the driver is accelerating the alternator disengages so all of the engine's power is channelled towards the car's performance. Other ancillaries, such as the air-conditioning compressor, are also able to disengage to improve the all round performance of the car. This intelligent use of drivetrain power is why EfficientDynamics technology has helped the BMW 7-Series become a class-leader in terms of performance, fuel consumption and emissions.
