The G10 was a race car, powered by a Shelby Mustang 289 cu in (4.74 L) V8.

The G10 was based on the already racing proven space frame of the G4, with a new Glass-reinforced plastic body fitted, with MGB doors and windshield.

The engine would be fitted with that of the Ford small block, as it was used by the main rival of the G10, the Shelby Cobra, with the original prototype being fit with a standard model making 290 bhp (220 kW; 290 PS), and the later models being fit with a more powerful modified block making 350 bhp (260 kW; 350 PS)[1][2][3] The G11 was the road car conversion of the G10, however instead of using the Shelby engine unit found in the G10, it used a MGB 1800 unit, this being said, at least 1 of the units was fitted with the Shelby unit per owner request from factory.

[4][5][6][7] The G10 Remastered (sometimes called the "G10 RM") is a replica kit car of the original G10, fit now with a LS motor.

The car is hand-built to order by Ginetta, with a hand built interior.
