TheMcLaren M25 was anopen-wheel racing car, designed byJohn Barnard, and developed and built by British constructorMcLaren in 1973. It was based on the successfulMcLaren M23Formula One car. It was originally built with the intention to be aFormula 5000 car, but it did not compete in any F5000 races, and didn't even contest in a motor race until 1976, which by that, was too late, since Formula 5000 racing (in its original guise) had folded. It then became aFormula One car forEmilio de Villota, and was equipped with a 3.0 L (180 cu in)Ford-Cosworth DFVV8 engine, where it only entered one World Championship Grand Prix, the1978 Spanish Grand Prix. de Villota damaged the car in an accident during the practice session for the race, so the team reverted his car back to theM23.[1][2][3][4][5]
