At next month's Frankfurt Motor Show, BMW will showcase a 7 Series V8 engine combined with an electric motor that together produce a power package of 465 horsepower with fuel consumption of only 9.4 litres.
The 15-kilowatt/20hp electric motor is integrated into the automatic gearbox. Acceleration from zero to 100kph is 4.9 seconds, with the top speed electronically regulated at 250kph. Roll-resistant 245/45 R19 tyres help improve consumption.
Brake-regeneration energy is stored in a lithium-ion battery pack positioned in the boot. The electric motor both acts as a support during acceleration and helps reduce consumption at a constant speed. It also supplies energy for the air-conditioner and 12-volt onboard energy. Similar to the technology already used in the Toyota Prius, the driver can monitor energy usage on a special display.
The exterior of the BMW 7 Active Hybrid stands out with its 19-inch aerodynamically styled alloys and "blue-water metallic" colour. Standard equipment includes Dynamic Damiping Control, front, side and head air bags, crash-active head support and run-flat tyres.
