Gordon Murray Automotive’s Goodwood presence is shaping up to be one of the more compelling supercar moments of the season.
Ahead of the 2026 Festival of Speed, the Le Mans GTR prototype known as XP1 has been seen in British Racing Green, giving the longtail track car a suitably historic first impression before the hillclimb crowds arrive.
It joins a GMA display that will also include the first T.50S Niki Lauda customer car, along with prototypes of the T.33 Spider and S1 LM.
At a glance
- GMA’s Le Mans GTR XP1 prototype has appeared ahead of the 2026 Goodwood Festival of Speed.
- The track-focused longtail supercar uses a naturally aspirated V12 that revs to 12,100 rpm and is paired with a 6-speed manual gearbox.
- Production of the Le Mans GTR is limited to 24 units, adding weight to its Goodwood debut.
A British Racing Green XP1 arrives at Goodwood
The Le Mans GTR is not simply another variation on Gordon Murray Automotive’s lightweight supercar theme.
Its British Racing Green finish gives XP1 a visual link to motorsport history without leaning into nostalgia too heavily, which feels appropriate for a car shaped around modern track use rather than retro theatre.
Goodwood is a natural stage for it.
The Festival of Speed begins on July 9, and the mix of road cars, prototypes and historic racers should give the Le Mans GTR the right context among machinery that treats performance as something mechanical, physical and loud.
Longtail aero and a 12,100 rpm V12
The Le Mans GTR takes inspiration from endurance racing icons including the Matra-Simca MS660, Porsche 917 and Alfa Romeo Tipo 33/3.
That influence is clearest in the car’s longtail profile and aggressive aerodynamic package, both of which separate it from GMA’s more road-biased designs.
The technical headline is equally pure.
Power comes from a naturally aspirated V12 that revs to 12,100 rpm, matched to a 6-speed manual gearbox rather than a paddle-shift transmission.
In an era where track-focused supercars often chase digital speed through hybrid assistance and automated gearshifts, the Le Mans GTR is more narrowly aimed at drivers who still want involvement to sit at the centre of the experience.

The Le Mans GTR will be a rare object by any measure, but its appeal is less about scarcity alone than the clarity of its brief.
With XP1 now at Goodwood, GMA has a chance to show how far its analogue performance philosophy can stretch when the road-car rulebook is moved aside.
