Gordon Murray S1 Unveiled as a Road‑Focused McLaren F1 Evolution

Replacing extreme fixed aero with integrated active systems and softer suspension, GMSV says the S1 is tuned to make a high‑revving, three‑seat V12 supercar usable on public roads.

Overview

Gordon Murray Special Vehicles revealed the S1 at The Quail during Monterey Car Week on Friday, confirming a naturally aspirated 4.2‑liter Cosworth V12 that makes about 680–681 hp, a six‑speed manual gearbox and a 12,100 rpm limiter.
The S1 uses the same carbon‑fiber monocoque and proportions as the track‑only S1 LM but features all‑new exterior panels and replaces large fixed wings with an integrated active aero system focused on mechanical grip.
Ride height is raised roughly 10 mm versus the LM and dampers are retuned for more compliance to improve road usability without sacrificing steering feedback.
The cabin keeps the McLaren F1‑style central driving seat and three‑across layout while adding dihedral doors, greater sound deadening, updated infotainment and a lightweight audio system for longer trips.
Production is capped at 64 individually commissioned cars with pricing and delivery timing still undisclosed, a move that positions the S1 between ultra‑rare track specials and high‑value road collectorship and may drive strong demand from wealthy buyers.
