Lamborghini Reventón is a mid-engined sports car that debuted at the 2007 Frankfurt Auto Show It will be the most powerful and expensive Lamborghini to date, costing one million euro. The official press release states that only 20 will be built, but it is rumoured that the total number could be 100. The exterior styling was inspired by the F-22 Raptor. Although the exterior is partially new, almost the entire mechanics (including the engine) are taken directly from the Murciélago LP640.  Initial reports suggest that the 6.5 litre V12 may receive a power boost of approximately 15 kilowatts (20 horsepower), bringing the new ouput close to 490 kW (650 horsepower).  In spite of this, and the car's carbon fibre components, the Reventón accelerates to 100 km/h (62 mph) in the same time as the Murciélago LP640 (3.4 seconds).  

The Reventón is named after a fighting bull according to Lamborghini tradition. The car's namesake, owned by the Don Rodríguez family, is best known for killing famed bullfighter Félix Guzmán in 1943. Reventón means "explosion" or "burst" in Spanish, when used as a noun.  For Lamborghini,  Reventón means "he who is used to making things burst".
