History

The Ginetta G23 was a prototype concept convertible, in plastic material; with 2 doors and 2 separate front seats. This 2-seater sports car built only in 1981 and did not make planned full production. A follow-on from the G21 as a 2-door convertible prototype developed from the previous Ginetta G21 but with more modern look and pop up headlights. The cars were fitted with the same a 2.8 litre Ford V6 OHV petrol engine and a planned cost of around £7,000 with option for a hardtop.

The engine was the heavy Ford unit but with good weight distribution of 49% to the front, and 51% at the rear with a turning circle: 35 ft. 10.7 capable of producing around 130 bhp with a single Weber twin barrel carburettor and a top speed of over 200 km/h. The engine was mated to a manual 4-speed gearbox and power was sent to the rear wheels with option for overdrive.
