The most technically accomplished road car yet built has come to the end of its seven-year production cycle.Bugatti, a brand under the VW Group, has announced it has sold the very last of its 300 unit Veyron production. The Veyron, powered by an eight-litre, quad-turbo, W16 engine, set many records in its short prodiuction life and captured the imagination of automotive enthusiasts like few other products.CARTOONISH NUMBERSFabled for its brutal power (in SuperSport trim it’s good for 895kW/1500Nm) and fantasy engineering details (it has 10 radiators, for instance) the Veyron is a car like no other - making Lamborghinis and Ferraris seem, well, a trifle underwhelming...Its cartoonish performance numbers, headlined by a topspeed of 430km/h, guarantee that its status as the most over-engineered (and fastest) internal combustion car will never be surpassed. It’s not all bad news for followers of the French brand, though. The Veyron’s convertible sibling, Bugatti’s Grand Sport, will remain available to customers for the time being. Although his identity is being secret, Bugatti says its last Veyron will be delivered to a European customer by the third quarter of 2011, signalling an end to a rather special chapter in the history of supercars.
