The Porsche V10 engine is a naturally-aspirated, V-10, internal combustion piston engine, designed and developed by Porsche, originally as a concept design for Formula One motor racing in the 1990s, and later Le Mans racing, but eventually used in the Porsche Carrera GT sports car; between 2003 and 2007. The engine is derived from the unsuccessful Porsche 3512 3.5-liter 80° V12 engine, used in the early 1990s.^{[3][4][5][6][7][8][9][10][11][12][13]}
