The T33 Spider will feature the same 609bhp 3.9-liter V12 engine found in the coupé version, which is a modified form of the Cosworth-engineered power unit utilized in the T50 hypercar. Only 100 models of the T33 Spider will be created, with a price tag of £1.8 million. An official concept drawing of the Gordon Murray T33 Spider has been released.
