The design of the GMA T.33 is claimed to be inspired by grand tourers of the 1960s,[1] such as the Ferrari Dino and Lamborghini Miura.

The T.33 has a luggage capacity of 280 litres (74 US gal), divided between a front trunk and two compartments ahead of the rear wheels.

[2] The T.33 is powered by the same Cosworth V12 engine as the T.50, with 3.99 L (243 cu in) of displacement and four valves per cylinder.

[3] Power is sent to the rear wheels via a standard 6-speed Xtrac manual transmission.

[4] GMA plans to build 100 customer cars at its Surrey production site.
