Brabham BT46 was designed by Gordon Murray for 1978 Formula 1 season. The car was powered by a flat-12 Alfa Romeo engine, and raced by Niki Lauda and John Watson. The car won one race in this form (Lauda in Italian Grand Prix) and scored sufficient points for the team to finish third in the constructors championship. The “B” variant of the car, also known as the “fan car”, was introduced at the 1978 Swedish Grand Prix as a counter to the dominant ground-effect Lotus 79. The BT46B generated an immense amount of downforce by means of a fan, claimed to be for increased cooling, but which also extracted air from beneath the car. The car only raced once in this configuration in the Formula One World Championship—when Niki Lauda won the 1978 Swedish Grand Prix at Anderstorp. As to John Watson, he managed to score second place in Italy and to finish 3rd in South Africa and Great Britain. In Monaco Grand Prix, the race represented in this scale model, Watson was 4th.
