Maserati 250F (1957) Juan Manuel Fangio – Despite just eight grand prix wins and a single drivers' title, the paucity of results makes no difference to the 250F's reputation as one of the finest and most graceful F1 cars ever built.
Lotus 25 (1963) Jim Clark – Introduced halfway through 1962, the Lotus 25 revolutionized racing car construction with the "monocoque" chassis.
Brabham BT20 (1966) Jack Brabham – Initially using a BT19 (almost identical to the BT20,) Brabham won four grands prix to take his third title and become the first -- and in all probability -- the only man to win a championship in a car bearing his own name.
The basic profile of F1 cars was altered forever in 1970 when Colin Chapman produced the Lotus 72. Amazingly, the Lotus 72 continued to be raced by the works team and privateers into 1975, five years after its conception.
