The GMSV S1 LM is the first ever commission executed by Gordon Murray Special Vehicles. As GMSV's first vehicle, 'S1' denotes 'Special One', born from the customer's passion for Gordon's 1990s designs and his landmark 1995 win at Le Mans. The timeless design pays homage to the beauty of Murray's original Le Mans-winning race car featuring prominent high-downforce aerodynamic elements. The primary focus of this project was to push the seven principles of Prof. Gordon Murray further than ever before with a particular emphasis on exclusivity, return to beauty, engineering art, lightweightness, and driving perfection.

Professor Gordon Murray, Group Executive Chairman: "I love timeless design. I never want us to join the race to make the most outrageous looking supercar at expense of balance, beauty and proportion. Look at the result, the car is timeless and beautiful."

Its profile features a newly lowered roofline and every surface is completely new, made from ultra-lightweight carbon fibre body panels. The aero package is specific to S1 LM, with a front splitter, rear diffuser, and dual element rear wing that together deliver significant downforce and stability. At both ends, Le Mans-inspired lights feature precision-engineered housings that flow seamlessly with the LM's sculpted bodywork.

Building on Gordon Murray's belief that the engine is the heart of the car and represents at least half of the experience, the S1 LM places its masterpiece at the very centre. The removal of the rear fan and oil cooling pack frees space to house a unique and exclusive 4.3-litre V12, producing over 700 PS - paired with a bespoke Inconel exhaust system, wrapped in 18-karat gold-foiled heat shielding. Engine development focused on larger displacement, lighter internals, and a higher compression ratio, maximising power, torque, and responsiveness. Capable of revving to 12,100 rpm, the V12 delivers a distinctive harmony through its four centrally mounted exhausts, inspired by the 1995 Le Mans-winning legend.

The manual gearbox was developed using the T.50s casing with T.50 internals and optimised linkage and set-up to deliver short rifle-bolt throws. Suspension is bespoke, with new geometry, a lower ride height, and unique damper settings to deliver a sharp and highly connected driving experience. The innovative solid-mounted engine enables the purest expression of transient handling while minimising unwanted noise and vibration.

The unique, race-inspired cockpit of the S1 LM is ergonomically designed around its central driving position, creating a fighter jet-style environment with minimalist, skeletal architecture, built on one of Gordon Murray's seven principles: engineering art. The interior explores new lightweighting concepts, utilises the finest materials, and showcases bespoke craftsmanship at every touchpoint, delivering precision that embodies its motorsports pedigree.

The Bespoke division of GMSV will build the client just five of these ultra-exclusive, road-legal S1 LM models for an undisclosed price, with deliveries scheduled to begin in 2026.
