Munich - BMW is showcasing at the Frankfurt Motor Show in September a BMW 7-Series V8 combined with an electric motor that together produce a power package of 465 hp with a fuel consumption of only 9.4 litres.
The 15 kW/20 hp electric motor is integrated into the automatic gearbox. Acceleration from zero to 100 km/h is in 4.9 seconds with the top speed electronically regulated at 250 km/h. Roll resistance 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 acts both as a support during acceleration and also helps reduce consumption at a constant speed. It also supplies energy for the air conditioner and 12 V onboard energy. Similar to the technology already used in the Toyota Prius, the driver can monitor energy usage on a special display.
From the exterior the BMW 7 Active Hybrid stand out with its 19-inch aerodynamically-styled alloys and 'bluewater metallic' colour. Standard equipment includes Dynamic Damping Control, front, side and head airbags, crash-active head support and run-flat tyres.
