The design used the Ford Cortina Mk3/Mk4 drivetrain and parts installed in a galvanized steel chassis of Ginetta's own construction. Originally, only four-cylinder engines could be fitted, but the G28's taller bonnetline made room for Ford's Cologne V6 engine. The bodywork was fibreglass, although the doors were the Ford Fiesta's steel units. The rear window on the fastback designs was also from the Fiesta, while the sportier notchbacks used the small window from the Sierra XR4i. 280 G26 were built. While the G31 was the last addition to the G26 line, it sold pretty well, with around 70 cars finished. Six G28 and fourteen G30 were finished, although since these cars were only available as kits it is unknown how many kits were actually sold. The total production of the G26 and its derivatives is about 370 cars.
