The March factory became involved in building production chassis for the new IMSA GTP Championship in 1982. They would later build chassis for BMW and Nissan. The very first car was the radical BMW 81P, also known as BMW M1C. It was produced for BMW North America in 1981. The car would be powered by a 3,5L in line 6 cylinder and later a 2,0L 4 cylinder Tc. After a somewhat unsuccessful season, the project was dropped as BMW North America's interest waned. The project was not to be completely forgotten, as March was working on an improved version of the chassis. Adrian Newey completely reworked the chassis. It would be a true customer car, as March did not intend to race it themselves. The car was designed to be easy to maintain and set-up. It was also built in order to use a wide range of available engines. The suspension system was a classic outboard coil/damper, double wishbone front and rear. The very first season for the 82G saw the Bob Garretson car finish second at Sebring, then the drivers had some high placings, but no victory in the end. Things would change in 1983, with Al Holbert purchasing a 83G version, using a Chevrolet powerplant in the first place, then a flat 6 Tc Porsche. He took six wins and the 1983 GTP crown. 1984 was by far the most successful season for March, with Bill Whittington and Randy Lanier taking seven wins and the title. They defeated the new Porsche 962, who was just entering the GTP series. While Porsche would go on and dominate the 1985 Championship, the March racers would fill in the IMSA GTP fields. The 83Gs, 84Gs and 85Gs were commonplace, usually powered by Chevrolet, Buick or Porsche powerplants. Here are the cars that were built :



  • 4 82Gs
  • 5 83Gs
  • 7 84Gs
  • 11 85Gs
  • 11 86Gs(including BMW and Nissan)
