History

The G4 arrived in 1961 as Ginetta's first car that could genuinely serve double duty as a road and competition machine. Clothed in a glass-fibre body over a tubular steel spaceframe and initially powered by the 997cc Ford 105E engine, the G4 weighed around 400 kg — light enough for go-kart reflexes and a claimed 120 mph top speed with larger engines. About 200 Series I cars were built between 1961 and 1963.

The Series II of 1963 brought a revised, longer-tailed body, while the Series III (1966) adopted a new, stronger square-tube spaceframe and Triumph Herald front suspension. Across the original 1961–1969 run more than 500 G4s were sold, the majority as kits. The nameplate returned for a Series IV from 1981 to 1984, now 51 mm wider and 76 mm longer than the III, before being superseded by the G27.
