The Brabham BT21 was a Formula racing car that Brabham built in 1966 in large numbers and delivered to private individuals; 110 vehicles were manufactured with Ford engines.
A race car designed Ron Tauranac most were used as Formula 3 cars, some were built for the American Formula B and were given the designation 21B . The cars for the Formule Libre ran under the code 21C .
The first BT21 arrived in 1966 at the international racetracks.
The chassis was flatter than the BT18 , the suspension was revised and the body completely rebuilt the body was slimmer but had a wider track. As engines 1966 and 1967 were a Cosworth MAE engine with 125 hp and 1968 a Holbay unit used a smaller amount with the 1600cc Lotus-Ford Twin Cam.
Privateers like Peter Westbury with his Felday Engineering Ltd. had much success with the BT21 in 1967. In 1968, the BT21 became a serious opponent with the new Tecno and the wins in Formula 3 were less.
The BT21B has therefore made some changes.
The car got wider wheels and a sturdier tubular frame that came from the BT23 , a Formula 2 car. This remedied the deficiencies. In 1969, the BT21 was slowly replaced by the BT28 .
