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 1971 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 1.6 L (98 cu in) 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]
The German automobile manufacturer/brand BMW has been involved in Formula One in a number of capacities since the inauguration of the World Drivers' Championship in 1950. The company entered occasional races in the 1950s and 1960s, before building the BMW M12/13 inline-four turbocharged engine in the 1980s. This engine was the result of a deal between BMW and Brabham, which resulted in the team's chassis being powered by BMW engines from 1982 until 1987, a period in which Nelson Piquet won the 1983 championship driving a Brabham BT52-BMW. BMW also supplied the M12/13 on a customer basis to the ATS, Arrows, Benetton and Ligier teams during this period, with various degrees of success. In 1988, Brabham temporarily withdrew from the sport and BMW withdrew its official backing from the engines, which were still used by the Arrows team under the Megatron badge. Turbocharged engines were banned by the revised Formula One Technical Regulations for 1989, rendering the M12/13 obsolete.
