Lamborghini Reventón

The development of a successor to the Murciélago was widely speculated in the motoring press as the supercar approached the end of its first decade in production. Spy photos published on the internet in January 2010 showed a camouflaged Lamborghini prototype undergoing winter testing.^[26] In December 2010 Autocar published a test drive of the new prototype however very little was released. Even the name was a mystery up until it was reported that Lamborghini registered the name "Aventador" with the US trademark office.
