Gordon Murray Special Vehicles Reveals S1 LM and Le Mans GTR

Gordon Murray Special Vehicles is starting with two cars that turn racing history into distinct, low-volume road-going projects. The S1 LM draws on the McLaren F1 LM, while the Le Mans GTR reworks the longtail shape. Both use a naturally aspirated V-12 and a six-speed manual, but the S1 LM is further along and has the clearer specification so far.

A bespoke take on the F1 LM

Shown at The Quail during Monterey Car Week, the S1 LM is the first fully bespoke commission from the new division, a sister company to Gordon Murray Automotive. Its foundations are loosely related to the T.50, but the powertrain and aerodynamic approach set it apart. The Cosworth V-12 grows from 3.9 liters to 4.3 liters, produces more than 690 horsepower and can rev to 12,100 rpm.

The T.50’s distinctive rear-mounted fan is absent. Instead, the S1 LM generates downforce through conventional bodywork, including a fixed rear wing and a large front splitter. That change gives the car a different engineering character: the T.50 uses its fan as part of its aerodynamic concept, while the S1 LM relies on visible, fixed aero elements.

The design makes its reference plain. The doors, hood, front bumper and rear corners recall the McLaren F1 LM, the competition version of Murray’s earlier supercar. Philip Lee, CEO of Gordon Murray Group, said the customer who commissioned the S1 LM wanted that influence brought into a contemporary car. Murray described his design aim as preserving balance, beauty and proportion rather than pursuing an extreme appearance.

That brief has produced a car with a direct visual connection to Murray’s past, backed by a larger engine and modern aerodynamics. The relationship is especially clear in the way the S1 LM adapts recognizable F1 LM cues without simply reproducing the earlier car. For buyers, the mechanical headline is the high-revving 4.3-liter V-12; the styling gives the commission its historical point of reference.

Just five S1 LMs are planned, and the commissioning customer is set to take all five. The source provides no price or delivery timing for this model. That makes the S1 LM an unusually concentrated commission: a single buyer will receive the entire production run, rather than the cars being distributed among several collectors.

The Le Mans GTR looks further down the track

The second car, the Le Mans GTR, draws on the flowing forms of late-20th-century longtail racers, including designs by Murray and the Porsche 917. Its shape is intended to balance aerodynamic purpose with a clean profile. Murray says the project adds contemporary aerodynamics and a specially engineered chassis, engine and transmission to that longtail influence.

The displayed car is less advanced in its engineering development than the S1 LM. GMSV describes the completed version as a more track-focused offering than the T.50, though it has not supplied performance figures or detailed specifications. That positioning is the key distinction for now: the S1 LM has a stated output and rev limit, while the GTR’s intended role is clearer than its final numbers.

Like the S1 LM, the GTR uses a version of the naturally aspirated V-12 paired with a six-speed manual gearbox. GMSV says nearly every other aspect of the car will change, so the shared engine and transmission establish a family resemblance while leaving substantial room for the GTR’s own chassis and aerodynamic setup.

One known detail is the exhaust. With the rear fan removed, the system has been routed lower and made longer. The company says this layout should give the engine a deeper, bassier note than the sharper sound associated with its other V-12 cars. Test driver Dario Franchitti described the exhaust character as having “a little bit of Barry White in its voice.”

GMSV plans to begin Le Mans GTR deliveries in 2026. Production will total 24 cars, one for each hour of the race that gives the model its name. Every example is already allocated, and prices have not been disclosed; the source characterizes them as likely to be in seven figures.

Gordon Murray’s record includes the McLaren F1 GTR that won the 1995 24 Hours of Le Mans and took four of the top five positions. He formed Gordon Murray Automotive in 2017. The company says production allocations for the T.50, T.50s, T.33 and T.33 Spider have all been secured. GMSV now extends that small-run approach into individually tailored projects.

For now, the S1 LM is the more fully specified of the pair, with its 4.3-liter engine, output above 690 horsepower and 12,100-rpm limit. The Le Mans GTR’s appeal rests on its longtail design, manual V-12 layout and stated track focus, with its final engineering details still to come. Both cars are already spoken for, so the next meaningful update will be what the GTR’s completed specification adds to that promise.
