The use of clear panels even extends to the floorpan - meaning the view below your feet could be as exciting as the road ahead.

The former unveiled the technology first - on its Q7 SUV - while the latter said that it would put a unit into the Cayenne in the future. Audi"s hybrid layout uses the firm"s 350bhp 4.2-litre V8 engine mated to an electric motor, which boosts torque by 200Nm to 640Nm in total.
This allows the big off-roader to sprint from 0-60mph in only 6.8 seconds - in normal mode without the battery"s assistance, it takes 7.4 seconds - and still return fuel economy of 23.5mpg. A Q7 fitted with the system will go on sale in 2008, but Porsche would say only that its Cayenne hybrid would be ready for action by the end of the decade.
