The Ginetta G4 was the fourth model from the Ginetta Car Company and it was a slight deviation from their prior products. This model was intended for both the road and track. It featured a multi-tubular space frame chassis construction with double wishbones, coil springs and dampers in the front. A Ford live axle with upper trailing arms, coil springs, and dampers made up the rear suspension. Drum brakes that measured eight inches, located in the front and back, kept the vehicle in the driver's control. The engine was a Ford 105E unit that produced nearly 40 horsepower, which could carry the car to speeds of about 100 mph. The engine did not produce much power, but much like the rest of the vehicle employed lightweight construction.
Over the proceeding eight years, many improvements were made to the G4, including various engine options being offered. The list of engines included a Ford 109E, 1.3 Ford Classic, Ford 1.6 X-Flow, and a 1.5-liter Ford Cortina GT powerplant.
When first introduced the G4 was available only as a convertible. With the introduction of the Series II G4 in 1963, a Coupe version became available. Basically, it was a hardtop fitted to the convertible. It had Perspex rear and side windows which helped keep the weight to a minimum.
Other changes adopted to the SII were a BMC rear axle which replaced the Ford live axle. The Series I had tail fins; the Series II did not. Disc brakes were available which greatly improved the car's performance.
In 1966 the Series II was replaced by the Series III. The most visual changes were the pop-up front headlight that when not in use, rested in the front bumper.
By 1969 the production of the G4 came to a close with production surpassing the 500 mark.
The Ginetta G4/R was the racing version of the G4 road cars. Powering the G4/R was a Ford 105E engine and clothed in glass fiber GT-style bodywork and fitted with an updated suspension comprising of coil springs in the front and a Ford axle in the rear.
