Impressed by this Ford contracted Eric Broadley to develop the Mk6 and directly from this sprung the Ford GT40 series which dominated sports car racing until the end of the decade, winning the French 24 hour classic from 1966 to 1969.

During the mid-sixties, Broadley's latest sports car thinking resulted in the legendary T70 series of brawny V8-engined machines which first emerged in 1965 and immediately set the pace at home and overseas. Armed with an open Mk2 Spyder version, John Surtees won the first Can-Am Championship in 1966. Roger Penske knew a good thing when he saw one and was soon campaigning the later Mk3B (the closed coupe version) in long distance events. Driven by Mark Donohue and Chuck Parsons, the Penske Lola won the 1969 Daytona 24 Hours, proving the design’s reliability.

Notable victories for the T70 include Denny Hulme at the TT, the Players and Martini Trophies and Frank Gardner with the Brands Hatch and Mallory Park Guards Trophies. Other T70 winners included Jo Bonnier, Brian Redman, David Piper, Trevor Taylor and Paul Hawkins.
