Coupe
Chassis #: 83G-02
The Adrian Newey-designed March 83G had a fiberglass body, an aluminum honeycomb chassis, and plenty of downforce created by the winds and ground effects.

This particular example, chassis number 83G-02, is powered by a 383 cubic-inch overhead valve V-8 engine fitted with a Kinsler fuel injection system and develops an estimated 550 horsepower. There is a five-speed Hewland DGB transaxle and four-wheel hydraulic disc brakes.

This 83G, named the 'Spirit of Miami' was completed in January of 1983. It won back-to-back IMSA Championships in 1983 and 1984, and achieved six outright wins and 12 finishes of seventh or better in the top prototype category of IMSA racing. Its drivers include Al Holbert, Randy Lanier, Bill Whittington, and Don Whittington.

Al Holbert leased this car from the factory in 1983. It then won the 1983 Miami Grand Prix which helped Holbert win the 1983 IMSA Camel Championship. It was raced by Emerson Fittipaldi, who came out of retirement to drive it in the 1984 Miami Grand Prix.

Randy Lanier and Bill Whittington formed Blue Thunder Racing, and after its Miami race in February of 1984, acquired this March-Chevrolet. They then set seven qualifying lap records and two lap records, and to take three overall victories. Lanier would ultimately win the 1984 IMSA Championship.

One of the family members of one of the racing drivers purchased the car in 1989. It was given a full restoration in 2006. Currently the car is powered by a Boyd 383 CID Chevrolet small block engine.

Since its restoration, the car has been campaigned in two Historic Sportscar Racing events: at Sebring and Daytona.
