The verdict

What's good

Central driving position from McLaren F1's layout gives perfect spatial awareness at speed
4.3-litre V12 is enlarged specifically for this car — not shared with any other model
Only five cars exist globally, each built to individual owner specification throughout
Direct lineage to the McLaren F1 LM makes this a historically significant object

What's not

$20 million price ensures this will only ever be viewed in private collections
Extreme rarity means replacement parts require bespoke fabrication timelines
No active aerodynamics — downforce is passive and fixed for a single setup
Cabin comfort is compromised entirely in favor of driver-focused track ergonomics

The engine

Cosworth GMA

Naturally Aspirated V12

One of the lightest, highest-revving road-car V12s ever made, screaming to a 12,100-rpm limit with razor-sharp throttle response and a near-700 hp wail. It is a competition engine barely civilized for the street.

Designed by Gordon Murray Automotive and built by Cosworth in England, the 4.3-liter is a bored-out evolution of the 4.0-liter V12 created for the Murray T.50, itself a spiritual successor to the McLaren F1 Murray engineered.

It uses competition-grade hardware including titanium connecting rods, titanium valves and silicon-carbide-coated pistons, plus a dry-sump oiling system.
Its Inconel four-pipe exhaust is wrapped in 18-karat gold heat shielding, a deliberate homage to the gold-lined engine bay of the McLaren F1.
Murray designed the S1 LM as a tribute to the F1 GTR, with the V12 echoing the F1's central-driving-position, lightweight ethos.
