BMW counters with hybrid 7

Hot on the heels of Mercedes-Benz's S400 Hybrid concept, BMW has released details of its 7 Series ActiveHybrid concept, which, it says, combines a significant drop in fuel consumption with first-class dynamics.

Developed as part of BMW's EfficientDynamics strategy and based on the 750i, the concept mates a twin-turbo V8 petrol engine with an electric drive system.

Output of the conventional engine is 300 kW with a peak torque figure of 600 Nm, while the electric motor adds 15 kW and a readily-available 210 Nm.

This combination results in a reduction in fuel consumption and emissions of up to 15% compared with the same car using its combustion engine only, BMW says.

A high-performance lithium-ion battery located in the luggage compartment uses Brake Energy Regeneration to save the energy that would otherwise be wasted and power certain on-board functions.

Additional car functions are run completely under electric power while an Auto Start Stop function shuts down the combustion engine when idling, and automatically restarts it upon accelerating.

Both BMW and Mercedes-Benz's hybrid drive systems are based on technology developed in a joint venture between the companies.
