The Brabham BT50 was a Formula One racing car designed by Gordon Murray and powered by a turbo BMW engine. It was raced by the Brabham team, owned by Bernie Ecclestone, during the 1982 Formula One season. Driven by Nelson Piquet and Riccardo Patrese, it made its debut at the South African Grand Prix before being withdrawn for further development of its engine while the team reverted to the previous year's car, the Brabham BT49. On the reintroduction of the BT50, Piquet finished fifth in the Belgian Grand Prix. A few races later he drove it to a win in the Canadian Grand Prix. Later in the year it achieved three more finishes in the points for the team. During the second half of the season, Brabham implemented the strategy of mid-race refueling. This allowed Piquet and Patrese to start the races relatively light and use their reduced weight to gain track position over their competitors before stopping to refuel. The poor reliability of the BT50 meant that they had only a few opportunities to demonstrate the strategy in practice.
