The Brabham BT52 was a Formula One car designed for the Brabham team by longtime Brabham designer Gordon Murray for the 1983 season. The car ran on Michelin tyres and was powered by the massively powerful BMW M12/13 turbocharged engine which in 1983 produced a maximum of approximately 800 bhp (600 kW) in qualifying trim, detuned to around 640 bhp (480 kW) for the races proper. Its drivers were 1981 World Champion Nelson Piquet and Riccardo Patrese.
