Frankfurt Motor Show Tinkers BMW With Hybrid Car2008 GMC Yukon Hybrid Car
Frankfurt Motor Show: BMW Vision EfficientDynamics concept car
This extraordinary machine is a vision of a BMW supercar for the year 2020.
While BMW, Mercedes and Audi normally match each other move-for-move, this is an entirely different idea from the big-engined and thirsty Mercedes SLS and Audi R8. It's compact, light and almost unbelievably efficient.
The drivetrain consists of a mid-mounted three-cylinder 163bhp diesel engine, boosted by a hybrid electric motor. It goes through a six-speed dual-clutch transmission to the rear wheels.
But there's an extra electric motor driving the front wheels. This boosts total system power to 365bhp for short periods of acceleration, and gives the car all-wheel-drive traction and the performance to match today's BMW M3.
Yet the CO2 emissions figure is just 99g/km. It can also run emissions-free as a plug-in hybrid for short journeys.
Encouragingly, BMW says all these drivetrain components are well into the testing phase and they are confident of their practicability for production.
The body is, say the designers, 'layered'. The panels sit proud of the understructure, and a layer of air goes into the gap and allows very fine aerodynamic control. It reduces turbulence, controls lift and manages engine and battery cooling.
BMW also launched two production petrol hybrid cars, a high-performance X6 and a super-economical 7-series. But these are mainly aimed at the USA – in Britain we buy our economical BMWs as diesels.

When we think of taking care of the environment, we think of the future and the long-term effects of environmentally hazardous human activities and inventions. It is a good thing that automobile companies nowadays include environment-friendly innovations in their visions for their cars in the pipeline.
