In the vernacular, it is also used to define a very large party or a night in town. Reventón means 'small explosion' or 'burst' in Spanish, when used as a noun. The bull, raised by Don Heriberto Rodriguez, was best known for killing famed Mexican bullfighter Felix Guzman in 1943. The car is named after a fighting bull, in line with Lamborghini tradition. According to the official press release, the Reventón's exterior styling was inspired by 'the fastest airplanes'. While the exterior is new, almost all the mechanical elements, including the engine, are sourced directly from the Murciélago LP 640. Each car is stamped with its number in the sequence of 20 between the driver and passenger seats. The official press release stated that only 20 vehicles would be sold to the public, with one additional car (marked as 00/20) produced for the Lamborghini museum. The Lamborghini Reventón ( Spanish pronunciation: ) is a mid-engine limited production sports car that debuted at the 2007 Frankfurt Motor Show.
