BMW EfficientDynamics is found in every BMW. It’s based on principles that reduce consumption and emissions, while increasing the joy of driving. BMW ActiveHybrid is a new form of intelligent energy management. It’s yet another step towards significantly reducing emissions – without losing a second of behind-the-wheel thrills. For the BMW ActiveHybrid 7 that means 15% lower consumption than then BMW 750i.
Thanks to the Hybrid Start Stop function, there’s no unnecessary crankshaft rotation from the V-8 engine. The sophisticated hybrid management system ensures that energy from braking is temporarily stores and then reused to power the vehicle. The battery charge status and deployment of the electric motor are displayed below the tachometer. The iDrive display shows the energy flow and energy efficiency over the previous fifteen minutes in detail.

The TwinPower turbochargers charge the V-8 engine to 400 hp. The electric motor ensures the car is always in the optimal load ranges while the High Precision Injection system guarantees the perfect mix of fuel and air. Because almost all the accessories are disconnected from the engine, the system’s output is always maximized. The hybrid management system knows when power can be regained or is needed, and how it needs to be distributed between the traditional and high-voltage networks. Sophisticated software determines the gear and motor control and engages the Hybrid Start Stop function, as well as the Brake Energy Regeneration system when necessary. At the same time, the hybrid management system protects the battery against overload. Most importantly, the electronics transfer between different driving conditions is so seamless, the driver doesn’t even feel the change.

The BMW ActiveHybrid 7 is dynamic, sporty, AND efficient, cultivated and responsible. A BMW makes no compromises. The BMW ActiveHybrid 7 is the best proof that opposites are completely complementary.
