GMA S1: The McLaren F1 Reborn With A 681 HP V12

Gordon Murray Special Vehicles has pulled the wraps off the new S1 at The Quail during Monterey Car Week, a limited-run V12 supercar developed from the S1 LM track special and aimed at long-distance touring. With its three-seat layout, central driving position, naturally aspirated Cosworth V12, and focus on low weight, it reads as a modern McLaren F1 in everything but name.

The S1 sits on a carbon fiber monocoque related to the S1 LM but trades that car's fixed aero hardware for smoother bodywork and active rear aerodynamics. Ride height is raised and the suspension is softened for comfort, yet target weight still undercuts the GMA T.50, Murray's earlier F1-inspired supercar, and stays in the same ballpark as his T.33 and T.50 spin-offs.

Power comes from a custom 4.2-liter Cosworth V12 rated at up to 681 horsepower and spinning to 12,100 rpm. Gordon Murray says the engine delivers about 369 pound-feet of torque, with most of that available from low revs for strong real-world response rather than lap-time chasing. Silicon carbide-coated lightweight pistons, titanium valves and connecting rods, and a dry-sump oiling system underline the racing flavor.

The V12 sends power through a six-speed manual gearbox with a taller touring sixth gear and straighter cable routing to sharpen the shift. The S1 keeps the S1 LM's track width, lightweight suspension layout, and wider tires, but ride height is up by about 0.4 inch and damping is reworked for more compliance while aiming to preserve the crisp steering feel seen on earlier GMA models like the T.33 Spider.

An integrated active rear aero system replaces the S1 LM's large fixed rear wing, long front splitter, and deep side skirts. Gordon Murray Special Vehicles says the aero package is tuned for high-speed stability and braking support rather than headline downforce numbers, with overall grip relying on mechanical balance instead of race-style bodywork.
