The GMA T.50 or Gordon Murray Automotive Type 50 is a sports car manufactured by Gordon Murray Automotive. Designed by Gordon Murray and inspired by the McLaren F1, the T.50 is powered by an all-new bespoke 3,994 cc (4.0 L) naturally aspirated V12 engine developed by Cosworth. The engine is rated at 663 PS (488 kW; 654 hp) at 11,500 rpm with a maximum torque of 467 N⋅m (344 lbf⋅ft) at 9,000 rpm.
The T.50 achieves a dry weight of 997 kg (2,198 lb), making it lighter than the vast majority of vehicles in its class, with the naturally aspirated V12 weighing only 178 kg (392 lb), and the chassis is 30 kg (66 lb) lighter than the McLaren F1. As a result, the T.50 features one of the highest power-to-weight ratios amongst its class at 501 kW (672 hp) per tonne, while its engine attains a specific output of 122.1 kW (163.7 hp; 166 PS) per litre.

A distinctive feature of the GMA T.50 is the 8.5 kW 40 cm aerodynamic fan integrated into the rear of the car, powered by a 48 volt electrical motor. Inspired by the Brabham BT46B Formula One car, it is purpose-built to significantly improve the ground effect of the T.50. As the T.50 makes use of very aggressive and steep angled rear diffusers, this in turn creates substantial turbulent or semi-stalled air passing over the diffuser when the T.50 has its fan inactive. By utilising the integrated aerodynamic fan, the T.50 can suck the air under the car at a 90-degree angle and provide a significant increase in overall downforce as it provides a laminar flow of air passing over the rear diffuser, thus, creating a greater level of suction in tandem with the Venturi effect, created underneath the car, ahead of the steep rear diffusers. This allows the T.50 to control the boundary layer and turbulent vortices underneath the car, significantly improving downforce. As a result of the T.50’s fan-assisted aerodynamic design, the need for any aerodynamic package on the front or rear of the T.50, such as a splitter, a wing or an aggressive aerodynamic design are considered ineffective in providing further downforce and are thus considered negligible, allowing a free form and flowing exterior design. The T.50 does make use of active aero spoilers however, that operate in conjunction with the aerodynamic fan. The active aero and fan functionality of the car is dependent on the driver selected mode which is provided in six presets made available in the cockpit of the car. The fan assisted aero design allows for a 30% increase in downforce when a 'high downforce' mode is selected, channelling air through aero ducts perpendicular to the airflow underneath the car, providing a high suction ground effect. Furthermore, under braking the T.50 provides 100% additional downforce by extending the active spoilers to a 45-degree angle of attack and utilising diffuser ducts. The T.50 can also achieve reductions in drag by selecting the specialised mode presets of 'streamline' and 'Vmax' modes, allowing for a 12.5% reduction in overall drag.
