The March 85G was the final evolution of the GTP/Group C prototype built by March Engineering (Oxfordshire, UK). With experience in Formula 1, March brought extensive knowledge in composite construction, innovative use of magnesium castings, and class-leading aerodynamics to their prototypes. Led by the renowned aerodynamicist Adrian Newey, the March prototypes feature state-of-the-art ground effects in part due to large tunnels under the car.
March built between 6 and 11 prototypes annually from 1982 through 1985, winning the IMSA championship in 1983 and 1984. Cars were built to fit the engine preferences of their customers and were fitted with Chevrolet, Porsche, and Buick engines, each requiring subtle differences in the body to facilitate radiator and intercooler placement.
IMSA GTP rules were simple to encourage multiple chassis manufacturers and engine combinations. There were no homologation requirements, but cars were required to have a closed cockpit with a fuel limit 120L/31.7 gallons, max height of 43 inches, max wheel diameter of 16 inches, driver's feet not extending past front axle, max width of 2M (79 inches), and minimum weight dependent upon engine displacement/HP.
Miss Budweiser 85G-04 was the 4th of 11 cars built in 1985 and was sold to DeAtley Racing of Vancouver, Washington. It campaigned during the 1995 IMSA season with Budweiser sponsorship by drivers Darin Brassfield, David Hobbs, Arie Luyendyk, and others.
