The March 712 (and its derivative, the March 712M) was an open-wheel Formula 2 race car, designed, developed and built by British manufacturer March, in 1971. It was very successful, with Swede Ronnie Peterson winning the 1972 European F2 Championship season in a Cosworth-powered 712. Peterson won 5 races that season, and took 6 podium finishes, as well as taking 7 pole positions, and 5 fastest laps. Peterson finished the championship in first place, with 54 points. Austrian Dieter Quester, also driving a March 712, finished the championship in third place, with 31 points, driving a BMW-powered 712. The 712 was powered by either a Ford-Cosworth FVA, or a BMW M12/7; which were both naturally-aspirated four-cylinder engines.[1] A sister variant of the car, called the March 71B (and its derivative, the March 71BM), was the Formula B (Atlantic) version of the car.[2] [3] [4]
