Gordon Murray Automotive (GMA) has whipped the wraps (and roof) off the T.33, revealing its first-ever drop-top supercar, the T.33 Spider. Only 100 units will be made.


Developed in parallel with the coupé variant, the T.33 Spider sports the same iStream ‘Ultralight’ carbon-fibre monocoque construction, which, GMA says, has been meticulously engineered to deliver the “exceptional” torsional stiffness needed for an “outstanding” ride, handling and agility without adding unnecessary weight. The hand-built drop-top weighs “just” 18 kg more (1 108 kg dry) than the coupé.

“From the first sketch, I knew the T.33 Spider would deliver a driving experience unlike anything else”

The bodywork wraps around a Cosworth GMA.2 V12 engine. The 3.9-litre naturally aspirated petrol unit produces 453 kW 451 Nm, the latter available from “only” 2 500 r/min (90 per cent of torque is maintained from 4 500 to 10 500 r/min). The full complement of power comes in at 10 250 r/min. The red line sits at 11 100 r/min. The T.33 Spider is offered exclusively with an Xtrac six-speed manual transmission, sending power to the rear axle.


Stopping power is provided by a Carbon Ceramic Matrix braking system. The arrangement comprises (front) 370 mm discs and six-piston monobloc callipers, while the rear set-up features 340 mm discs and four-piston monobloc callipers. Michelin Pilot Sport 4 S tyres are wrapped around 19-inch (front) and 20-inch (rear) alloy wheels.

“From the first sketch, I knew that, with its open cockpit and the incredible Cosworth GMA.2 V12 engine right behind you, the T.33 Spider would deliver a truly involving driving experience that’s quite unlike anything else,” said Professor Gordon Murray CBE.
