Brabham BT51

The Brabham BT51 was a Formula One racing car designed and built by the Brabham team. The car, which was tested by Nelson Piquet and Riccardo Patrese, was intended to race in the 1983 Formula One season. However, following a change in the rules for the 1983 season eliminating ground effect technology, the team had to abandon the ground effect-BT51 and build the BT52.
