The wraps are finally off the most talked-about car at this year's Tokyo motor show - Nissan's GT-R prototype.

Called the GT-R Proto, it's the strongest indication yet of how 2007's all-new GT-R will look.

Unlike previous models, the new GT-R is being purpose built as a sports coupe rather than derived from a saloon model.

This means Nissan plans to drop the 'Skyline' tag (a new Skyline range of saloons and coupes already exists in Japan) and call the new car simply GT-R.

That said, the Skyline GT-R bloodline is evident in the new design - the twin rear lamps remain and the coupe shape is still chunky and muscular.

And, for now at least, the Proto will have to rely on its looks - it has no interior or engine yet, and Nissan hasn't yet confirmed any technical details.

It's unlikely the new GT-R will disappoint, though. It's one of the most hotly anticipated cars of this decade, and Nissan is taking the time to get it right (bear in mind this car was first announced in 2001).

Extensive development and track testing is planned before Nissan commits itself to specific technical detail, but we're expecting at least 400bhp and, if the company's hard work pays off, 'ultimate driving pleasure' (their words...).

We'll find out whether the new GT-R lives up to its heritage in exactly two years' time - the new car is scheduled to make its debut at the Tokyo show in 2007.
