Gilbern
T11

Why it matters

The T11 was the last new design developed by Gilbern, a small British maker that built cars from 1959. It reached the stage of a drivable chassis and a single prototype before the company closed in 1973, so it stands as an unrealised successor to the marque's road cars.

History

The T11 was originally designed in late 1969 and was intended to appear at the Geneva motor show in 1971. Development began in 1970, with Trevor Fiore called in to style the body; a one-fifth clay model was made and passed to Specialised Mouldings to produce a mould for the body shell. Gilbern obtained a drivable chassis before the project was cancelled, with about 50,000 pounds said to have been spent.

The unfinished prototype passed to the owners club and later to a private person, and was eventually rebuilt on the road by an enthusiast, who fitted an Austin Maxi engine and gearbox behind the driver and later replaced the damaged engine with a Toyota 3S-GE unit.
