1983 March 83G

March Engineering built a single Formula 3 car in 1969, after which they made an ambitious announcement with plans for factory entries in Formula 1, Formula 2, Formula 3, Formula Ford and Can-Am racing events. The company's first Formula 1 victory was earned by Jackie Stewart, driving for Ken Tyrrell. The following years were met with modest levels of success, including 2nd in the championship in 1971. In 1977, the March Formula 1 team was sold to ATS.

After a halfhearted attempt to achieve Formula 1 success in 1981 and 1982, the company turned their engineering talents towards building Indy cars. This proved to be a successful venture, as the team won five straight Indy 500 victories for Cosworth-powered Marches between 1983 and 1987.

With the introduction of GTP/Group C sports car racing, March entered a car based on the M1C project they had worked on for BMW. By 1983, designer Adrian Newey was working for March and was tasked with designing the 83G. The 83G was an evolution of the 82G that in turn was inspired by the M1C.

Five 83G examples were produced for the 1983 season, four for GTP and one for Nissan to run in Group C. Two of the GTP cars were sold to Al Holbert, one with Chevrolet power and one (83G-4) with a Porsche flat six derived from the 935.
