For its first-ever vehicle, Gordon Murray Automotive wants to rewrite the supercar rulebook. The T.50 will be the purest, lightest, most driver-focused supercar ever built ? a spiritual successor to the iconic McLaren F1 and made to the same exacting standards.
Describing its approach as ‘unflinching dedication’, the T.50 uses advanced engineering across all of its components. GMA recruited Cosworth as a trusted technical partner to design, develop and manufacture an all-new exclusive V12 engine to power the T.50.

Cosworth’s brief from GMA was clear ? the engine had to be light. It had to have the fastest response time of any engine ever built for the road, replicating the illustrious McLaren F1 targets and delivering the highest-revving machine ever made for a production car with unrivalled power-to-weight. The brief also extended to aesthetics and aural experience by developing a characterful V12 which sounds superb and looks good ? a clean design with no coverings or belt-driven ancillaries. A crucial part of the brief was to keep the capacity of the T. 50’s V12 as small as possible. With a clear view of the required acceleration and torque, and the goal of a sub-1,000kg total vehicle weight, Cosworth proposed the capacity to be just 3.9-litres while still achieving supercar performance.
