What is the fastest Lotus ever made?

Colin Chapman established Lotus Engineering Ltd in 1952 at Hornsey, UK. Lotus achieved rapid success with the 1953 Mk 6, and the 1954 Mk 8, the first aerodynamic sports racer. A new Formula 2 regulation was announced for 1957 and in Britain several organizers ran races for the new regulations during the course of 1956. Most of the cars entered that year were sports cars and they included a large number of Lotus 11s, the definitive Coventry Climax powered sports racer, led by the Team Lotus entries for Chapman, driven by Cliff Allison and Reg Bricknell.
