Gordon Murray S1 brings a 12,100-rpm V12 and six-speed manual to a more road-focused supercar

In the 2026 supercar market, a naturally aspirated V12, a six-speed manual and a relentless focus on low mass have become rare enough to function as a form of luxury.

Gordon Murray Special Vehicles unveiled the S1 at The Quail. It shares its core architecture with the more track-focused S1 LM, but it is not simply a rebodied version. The S1 has been reworked around a more usable road brief.

Its Cosworth 4.2-litre naturally aspirated V12 produces about 680 hp at around 12,100 rpm, while fuel cut arrives at roughly 12,400 rpm. Those are separate figures: 12,400 rpm should not be described as the peak-power speed. A six-speed manual remains central to the package.

The S1 makes about 680 hp around 12,100 rpm, while fuel cut arrives around 12,400 rpm. The two figures should not be conflated.

The key idea is not just revs, but road use

The S1 keeps the underlying concept of the S1 LM, yet almost every exterior panel apart from the roof has been redesigned. Suspension is softer, ride height is increased by about 10 mm, and the car adds features such as greater sound insulation and opening windows.

Those changes are significant because Gordon Murray is not treating comfort as the opposite of driver involvement. The S1 is intended to preserve the lightweight, naturally aspirated, manual formula while making the car more realistic for long-distance road use.

Carbon fibre is used extensively, so low mass remains a central engineering priority even as the road car becomes more accommodating than the S1 LM.

McLaren F1 philosophy, not a new McLaren F1

Gordon Murray was one of the key figures behind the original McLaren F1. His more recent T.50 and T.33 projects have continued to emphasise low weight, naturally aspirated power and driver participation, making it easy to see a philosophical connection between the S1 and his earlier work.

That connection should not be overstated. The S1 is not a new McLaren F1 or a direct recreation. It sits within the GMSV Special Vehicles programme, separate from the regular GMA production line and aimed at rarer, more specialised projects.

Only 64 cars, reportedly all spoken for

Production is limited to 64 cars worldwide. Media reports say the allocation has already been fully spoken for. Unless official material explicitly describes the model as sold out, that should remain framed as reported information rather than an official sales declaration.

The demand also illustrates a broader shift in the collector market. As mainstream performance cars move deeper into hybridisation, turbocharging, automated transmissions and digital control, an analogue V12 manual supercar becomes more valuable precisely because it is no longer the norm.

Analogue luxury is about an experience, not just speed

The S1's appeal is not only that its Cosworth V12 revs beyond 12,000 rpm. It is the way the entire car is organised around low mass, natural aspiration, a manual gearbox and mechanical feedback.

For most buyers this is an unreachable corner of the market, but culturally it shows a clear split. The more mainstream performance cars become digital and electrified, the more room exists for ultra-low-volume makers to turn analogue driving into a top-tier luxury experience.

Move Auto's Take

The S1 is interesting because it does not define purity as discomfort. A mature road supercar should make its owner want to drive it properly and over distance, not simply move it between storage and a circuit. With V12s, manuals and low-mass engineering becoming increasingly scarce, Gordon Murray is effectively selling an entire way of driving that is disappearing elsewhere.
