The Brabham BT20 is a Formula One car used by the Brabham Formula One team in 1966 and 1967, as well as a number of privateers from 1967 to 1969. The BT20 was the direct successor to the Brabham BT19 which was driven to the World Constructors' title in 1966. The BT20 was driven in 7 out of the 9 races of Brabham's Constructors' Championship winning season in 1966, and the first three races en route to another championship in 1967. The BT20 was very successful in these seasons, scoring 7 podiums and one win (at the 1967 Monaco Grand Prix) in its first 10 entries.
