Italian expat Professor Gordon Murray has launched the T.33 Spider with two removable roof panels, a deployable rear window and a naturally aspirated Cosworth GMA.2 V12 behind the cabin.
Developed in parallel with the T.33 and sharing the same Ultralight carbon fibre monocoque construction, the T.33 Spider is engineered to deliver the exceptional torsional stiffness needed for an outstanding ride, handling, and agility without adding unnecessary weight.
“When drawing a car, I imagine what it's going to feel like to sit in and how it will feel to drive. So, from the first sketch, I knew that, with its open cockpit and the incredible Cosworth GMA.2 V12 engine behind you, the T.33 Spider would deliver a truly involving driving experience that’s quite unlike anything else. And while it’s still a mid-engine supercar, I wouldn’t accept any compromise on usability: this is why the T.33 Spider is unique in the supercar sector in delivering both onboard roof storage and a 295-litre luggage capacity”.
The car draws inspiration from the iconic designs of the 1960s, and Murray made it a point to keep the purity, balance, and overall beauty of the T.33.
The fixed section of the roof blends into the rear deck with louvres that aid engine cooling. And the ram induction airbox, mounted directly to the engine itself and a hallmark feature of the T.33, becomes even more distinctive on the Spider, especially without the roof panels.
Inside is a simple analogue instrument cluster dominated by a 120 mm centrally-mounted rev counter adjusted to 11,100 r/min. On either side are secondary displays for climate control and infotainment, the latter featuring wireless Apple CarPlay and Android Auto connectivity.
The T.33 Spider is centred around Gordon Murray Technologies’ iStream Ultralight carbon monocoque technology. Comprising carbon fibre composite panels bonded to extruded aluminium tubing triangulated at precision die-cast aluminium nodes, it delivers a body structure which provides the optimal balance of high stiffness, lightweight, and exceptional levels of safety and occupant protection.
Like the coupé, T.33 Spider features all-around double wishbone suspension made from lightweight aluminium. The high-pressure monotube dampers are of coilover design made from aluminium.
Following motorsport practice, the powertrain of the T.33 Spider is semi-structural, with the rear suspension mounted directly to the transmission casing.
A Carbon Ceramic Matrix (CCM) braking system has been developed specifically for T.33 and T.33 Spider. It comprises 370 mm x 34 mm discs, six-piston monobloc callipers on the front axle and 340 mm x 34 mm discs with four-piston monobloc callipers at the rear.
The dry-sump, 3,9-litre Cosworth engine features a naturally aspirated 65-degree cylinder bank angle, fed via the ram air scoop and four throttle bodies, together with two fuel injectors per cylinder.
Some 75% of the 451 Nm maximum rated torque is available from only 2 500 r/min, while 90% from 4 500 r/min -10 500 r/min. Maximum power of 460 kW is delivered at 10 250 r/min, with the engine electronically limited to 11 100 r/min – and weighs just 178 kg.
The T.33 Spider, just like the T.33, will be hand-built at Highams Park GMA's all-new bespoke headquarters at Windlesham in the UK, with the products tailored to specific customer requirements.
