Gordon Murray’s Special Vehicles division has revealed the GMSV S1, a touring-focused supercar directly homaged to the 1992 McLaren F1 road car. Limited to a production run of 64 units, the S1 features a naturally aspirated 4.2-litre Cosworth V12 producing 681 horsepower and a manual transmission, capturing the essence of the legendary design for 2026.
Here is the math. While the ultra-exclusive S1 LM was strictly limited to five units and built for track-inspired performance with aggressive downforce, the new S1 expands production to satisfy heavy customer demand for a more compliant, road-going grand tourer. But the balance sheet tells a different story regarding availability, as all 64 slots are already fully spoken for at an undisclosed multi-million dollar price point.
The Bottom Line
- Production Expansion: GMA is manufacturing 64 units of the S1, a significant volume increase compared to the five-unit run of the track-focused S1 LM and approaching the 100-unit limit of the standard T.50.
- Engineering Adjustments: The S1 retains the chassis and 4.2-litre Cosworth V12 architecture of the S1 LM, but is modified with a 10mm higher ride height, compliant dampers, and a longer sixth touring gear.
- Commercial Status: Despite the expanded production run, the vehicle’s entire allocation is entirely sold out, demonstrating resilient ultra-high-net-worth demand for analog, manual-transmission supercars.
Unpacking the Engineering and Design Shift
To understand the commercial positioning of the S1, one must evaluate its lineage against Gordon Murray’s previous offerings. Revealed a year prior, the S1 LM served as a limited customer commission honoring the 1995 Le Mans-winning McLaren F1 GTR. That vehicle prioritized extreme aerodynamics, featuring a prominent rear wing, front splitter, and side skirts. According to reporting by Top Gear, the S1 was born out of customer pressure from buyers who appreciated the central driving position and V12 mechanics of the LM but requested a cleaner aesthetic free of aggressive track elements.
Every exterior carbon panel on the S1—excluding the roof and engine cover—is completely new and distinct from the S1 LM. Design elements such as round lights set into the front bumper intakes and redesigned wheels directly reference Gordon Murray’s original 1992 McLaren F1 Monaco show car. Furthermore, the vehicle incorporates dihedral doors featuring proper drop-down glass, replacing fixed-window track layouts to improve usability during long-distance grand touring.
Powertrain Specifications and Market Comparables
Beneath the carbon-composite bodywork lies the same larger 4.2-litre naturally aspirated Cosworth V12 engine utilized in the S1 LM variant. The powerplant revs to 12,100 rpm, generating 681 bhp and 367 lb-ft of torque. However, engineers retuned the engine mapping to deliver maximum torque from just 2,500 rpm, optimizing low-end drivability for touring conditions. Power is routed through a six-speed manual gearbox augmented by a longer sixth gear ratio.
When positioned alongside other flagship hypercar releases from boutique British manufacturers, the production metrics highlight a deliberate niche strategy within the ultra-luxury automotive sector.
| Model | Production Volume | Engine Architecture | Core Design Intent |
|---|---|---|---|
| GMSV S1 LM | 5 Units | 4.2L Cosworth V12 | Track-inspired, high downforce |
| GMSV S1 | 64 Units | 4.2L Cosworth V12 | Road-focused grand touring |
| GMA T.50 | 100 Units | 3.9L Cosworth V12 | Lightweight analog supercar |
As noted by Gordon Murray in Top Gear coverage, producing 64 units brings the Special Vehicles division uncomfortably close to the 100-unit production ceiling of the T.50. Yet, management justified the exception due to the unique historical homage the vehicle represents. With the order book closed and production scheduled to satisfy an elite collector demographic, the S1 underscores the enduring market value of pure, non-hybridized internal combustion engines paired with manual transmissions.
