Brabham BT52
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 BMW M12/13 four-cylinder turbocharged engine, which in 1983 produced a maximum power of approximately 1,280 bhp (950 kW) in qualifying trim, detuned to around 850 bhp (630 kW) for the proper races. Its drivers were 1981 World Champion Nelson Piquet and Riccardo Patrese.
