The GMA S1 LM heavily resembles a remake of the famous McLaren F1 GTR car, with many of its design aspects being reminiscent of the famous racing model. It has a roof scoop, quad exhausts, air vents at the back of the front fenders and five-spoke wheels. Its track-intensive positioning is characterised by four circular tail-lamps at the rear, a revised diffuser and a multi-piece wing.
The S1 LM, compared to T.50, is at a lower ride height, a narrower headlight, a more expansive front splitter and a body comprising all completely new carbon-fibre panels that have been shaped to give aerodynamic advantage. It sheds the T.50s trademark fan exhaust, but does keep butterfly doors to set a dramatic note.
Empty, Cabin Racist Stripped-Out
Internally, the S1 LM inherits the classic three-seat layout interior championed by Gordon Murray, with the driver in the centre. Reflective of the stripped-out racing spirit, unlike the more luxurious-feeling interior of the T.50, this cockpit takes on a minimalist philosophy.
It comes with a race-spec steering wheel, of course, big lashings of carbon fibre in the finishes, bucket seats, tartan upholstery with bold red accents and even a wooden gear shifter, to take it back to an early era of race car interiors.
High-Revving V12 Powertrain
It is powered by a 4.3-litre naturally aspirated Cosworth V12, which is an evolution of its engine used in the T.50. The engine produces more than 700hp and an amazing 12,100rpm.
Solid-mounted to the chassis frame (for more precise cornering), the motor also gets gold foil heat shielding (similar to the McLaren F1). A 6-speed manual gearbox and custom suspension further refine the driving experience. As a result, the S1 LM is more focused than the T.50 in a purer way.
Inclusion and Deliveries
The S1 LM is only available in five units, and it is scheduled to be delivered in 2026; pricing remains undisclosed. This is not a mere dedication to Murray; that is at least part of GMA's program of Special Vehicles, it is also a celebration of his legacy, stretching the past and future of performance engineering into the present.
