GMSV S1

Monterey, California – 14 August 2026 – Gordon Murray Special Vehicles has revealed the new ‘S1’ supercar at The Quail during Monterey Car Week, a touring-focused evolution of the S1 LM that exudes timeless confidence and celebrates a unique approach to Driving Perfection.

The naturally aspirated, V12-powered, manual supercar is an evolution of the S1 LM platform, which is optimised for mechanical grip, rather than high downforce, to offer a distinctive driving experience. The revised suspension adds comfort and refinement for long distance journeys, while retaining Gordon Murray’s signature Driving Perfection philosophy. The S1 commission is the latest model from Gordon Murray Special Vehicles, where all seven design principles are pushed to their most extreme expression.

While the S1 shares its family DNA with the S1 LM (the Special One), its character and purpose are distinctly different. The S1 LM was conceived as the most intense, road-legal, race-inspired celebration of Gordon Murray’s 1995 Le Mans 24 Hours victory. The S1 evolves the elegant design language of the S1 LM, while reframing the set-up for fast, engaging, long-distance road driving.

The S1 removes the S1 LM’s large, fixed rear wing, long front splitter, and deep side skirts; every exterior body panel is new. The result is a cleaner silhouette inspired by classic proportions.

A new active rear aero system is integrated into the bodywork, adapting to the demands of high-speed stability and braking. The focus moves away from extreme downforce and towards mechanical grip, balance, and confidence on the road.

At the heart of the S1 is a bespoke 4.2-litre naturally aspirated Cosworth V12 producing up to 690 PS at a shrieking 12,100 rpm. Derived from the same lineage as the S1 LM engine, the 4.2-litre unit has been developed to deliver exceptional response, while retaining the sound, immediacy, and character expected from a Gordon Murray engine. The low-inertia, high-revving engine features a suite of competition-spec components such as silicon carbide-coated lightweight pistons, titanium valves, titanium connecting rods, and a dry-sump lubrication system. With effortless touring in mind the S1 features a broader torque range, delivering 80% of torque from just 2,500 rpm and around 500 Nm at 7,000 rpm.

The engine is paired with a six-speed manual gearbox, featuring a touring sixth gear as standard. New straighter gearbox cable routing helps deliver the precise, rifle-bolt shift feel that remains central to the car’s physical connection between driver and machine.

The S1 retains the S1 LM’s width, track, lightweight suspension architecture, and wider tyres, but ride height is increased by 10 mm and the damping is retuned for greater compliance while preserving steering precision, agility, and feedback.

Lightweight engineering remains fundamental. Ultra-lightweight carbon fibre body panels, lightweight suspension components, and Gordon Murray’s obsession with weight reduction contribute to an overall target weight below that of the T.50, despite the S1’s more luxurious cabin trim, enhanced sound system, and additional acoustic refinement.
