Gordon Murray T.33 Spider Revealed As Roofless Supercar With 11,100-RPM V12

When you decide to enjoy open-air motoring, the roof panels fit neatly into the 4.06 cubic foot front trunk. In most other supercars with removable hardtops, you have to make a choice between a sunlit cabin and storage space, but the T.33 has a trick up each of its sleeves. With the doors open, a button is revealed that opens a 3.18 ft³ storage compartment on each side, not dissimilar to the storage units on a Pagani Huayra, for example. And it still has a traditional frunk.

Whether you have the roof on or not, the Spider gets a deployable rear window that can be lowered for a more open feeling or raised for less cabin turbulence. Further bolstering its claims as a practical supercar is the T.33 Spider's inclusion of Apple CarPlay and Android Auto.

Here in the cabin, you'll find plenty of aluminum, carbon fiber, and leather, along with rear bulkhead trim that is now body-colored for a greater feeling of openness. The carbon fiber steering wheel is trimmed in leather, while the gear lever, pedals, and switchgear are machined from aluminum alloy. The bucket seats are fashioned from carbon fiber and dressed in a mix of leather and Alcantara, with the cockpit open for limitless customization based on the taste of the owner. Again, the design of the cabin shows how useful it is to develop two body styles based on the same car side by side - the cabin of the T.33 looks perfectly suited to drop-top driving.

The parallel development of the two variants also means that the Spider has remarkable torsional stiffness, being based on the same iStream carbon fiber monocoque as the coupe. As a result of GMA's fastidious attention to detail and obsession with saving weight, the Spider has a target dry weight of just 2,442.7 lbs - less than 40 lbs over the coupe's mass.

Another piece of the puzzle contributing to the T.33 Spider's undoubted brilliance is that GMA developed an electrohydraulic steering system. This provides the feel you expect from a traditional hydraulic power steering system but rather than a parasitic engine pump, this setup utilizes an on-demand electric pump, making even the steering as efficient as possible.

When it's time to stop, Carbon Ceramic Matrix brakes measuring 370 millimeters by 34 mm with six-piston calipers up front work with 340x34 mm four-piston brakes at the rear.

Lightweight forged aluminum wheels (19-inch in front, 20-inch at the rear) are wrapped in Michelin Pilot Sport 4 S tires. For such a low-volume special, these tires may seem a bit underwhelming, but this is again proof of GMA's mission to provide cars you love to drive. GMA specifically chose these tires for their all-weather brilliance and their ease of availability, thereby encouraging owners to use the car as much as possible.

Before they do, owners will have the opportunity to customize the car to their exact tastes, but four preselected design themes are already on offer for those who need a little inspiration. Two of these are based on two of GMA's core values, Return to Beauty and Engineering Art, while a third is based on the Murray Atholl tartan, and the final is inspired by Gordon's love of tropical shirts.

Just 100 examples will be made, as with GMA's previous supercars. The coupe sold out very fast, and as the last non-hybrid GMA, we suspect the Spider will be just as successful.

Given the T.50 has just been signed off to enter production, the development and homologation process for the T.33 is due to begin imminently. Unlike the T.50, however, the T.33 Coupe and Spider will be road legal in the US. It's priced at £1.89m before tax (approx. $2.4 million), but the price in dollars will fluctuate based on exchange rates at the time of ordering.

Production will begin in the summer of 2025, after the regular T.33, which enters production in the fall of 2024.
