The G10 and G11 were produced during the early 1960's and powered from V8 engines courtesy of Ford and MGB. The next Ginetta vehicle was the G12 which brought with it a rather experimental configuration with the driver sitting in front of the motor. It was a fairly uncommon setup though a proven way of achieving excellent balance and weight distribution.
The G12 utilized a mid-engine layout and was used as a competition car. At the racing debut of the G12 at Silverstone, it set a lap record. The following race at Snetterton, the G12 won its class. It was not uncommon for these small, lightweight machines to outpace the larger competitors, such as the mighty Shelby Cobras and Ford GT40s.
In total, there were around 33 (with as many as 50) examples of the G12 produced during the 1960s. Production ranged from 1966 through 1968.
The G12 had a multi-tubular space frame clothed in a lightweight fiberglass body weighing a mere 1200 pounds. Power was from a Lotus twin-cam 1600cc engine breathing through twin Weber carburetors. The engine was mated to a Hewland 5-speed transaxle sending the power to the rear wheels. In the front, the suspension was comprised of double wishbones with coil over shocks. The rear had double radius arms, upper transverse links, coil-over shocks, and lower wishbones. Girling disc brakes could be found on all four corners.

I will change the title as soon as I find the racing sereies where it competed
