Donkervoort GTO - Dutch supercar

The new Donkervoort GTO uses the 2.5-litre five-cylinder turbo from the Audi TT RS and, despite being the firm's largest-ever car, still weighs just 700kg - half the weight of a VW Golf.

The Caterham-style car a hefty 150mm wider and 350mm longer, says the firm, to accommodate Audi's longitudinally-mounted five-cylinder engine.

This motor has also been lightened by 30kg, again to aid weight distribution and handling.
