Bugatti Veyron Pur Sang

You'd better have cast-iron stones to steal Lamborghini's thunder at a motor show. Luckily, Bugatti rocked up with one very precious stone: the limited-to-five-models Pur Sang edition.

Unveiled at the 2007 Frankfurt motor show and translated as ‘pure blood', nothing changes mechanically barring a 100kg weight reduction. No, this Veyron is finished in raw aluminium and carbon fibre: basically, sans paint. Quite stunning, really.
