The Brabham BT3 is a Formula One racing car. It was the first Formula One design to be produced by Motor Racing Developments for the Brabham Racing Organisation, and debuted at the 1962 German Grand Prix. The Brabham BT3 was the vehicle with which team owner – then two-time World Champion – Jack Brabham, became the first driver ever to score World Championship points in a car bearing his own name, at the 1962 United States Grand Prix. The following year Brabham also became the first driver ever to win a Formula One race at the wheel of an eponymous car, again driving the BT3, at the 1963 Solitude Grand Prix. The BT3 design was modified only slightly to form the Tasman Series-specification Brabham BT4 cars.
