- The Final Gordon Murray S1 LM heads to auction on November 21.
- Winning bidder will be able to create full spec with Gordon Murray.
- Its V12 revs to 12,100 rpm, and the car has a $20M+ estimated price.
The Las Vegas Grand Prix is going to be an exciting event this year, and the hottest action could end up outside of the race track. Gordon Murray Special Vehicles will auction off the “final” S1 LM over there during the weekend. The sale of Chassis #1 will be the highlight of the amfAR benefit gala on November 21.
The S1 LM is an absolutely batty creation. Every car ever called a successor to the McLaren F1 can basically kick rocks compared to this thing.

It’s ultra-exclusive, hand-finished, and as driver-focused as it gets. Imagine everything Gordon Murray could’ve made the F1 into had he been able to use modern materials and techniques: that’s basically the S1 LM in a nutshell.

Just five S1 LMs will exist, echoing the five McLaren F1 LMs built to commemorate the F1 GTR’s 1995 Le Mans victory. Chassis #1 is the final allocation available for sale, and the winning bidder gets more than a car.
They’ll sit down with Murray himself to craft their own specification, mirroring the collaborative process of bespoke supercars from the 1990s.
What Powers It
Underneath its lightweight carbon bodywork lies a new 4.3-liter naturally aspirated GMA-Cosworth V12, engineered exclusively for the S1 LM. It produces more than 700 hp and revs to 12,100 rpm, paired with a six-speed manual gearbox and a target weight of just 957 kg (2,150 pounds).
Murray removed the rear fan and cooling pack to create space for the larger-displacement V12 and a bespoke Inconel exhaust wrapped in 18-karat gold heat shielding that, alongside the four central exhaust tips, nod directly to the 1995 Le Mans winner.

For Murray, the car carries personal meaning. He worked on the project during his cancer recovery, calling the focus required “a big part of getting me through that.”
RM Sotheby’s expects this to fetch somewhere around $20 million when it crosses the block. That no doubt has to do with scarcity, as GMSV sold all five units planned for production to one individual. The brand confirmed to Carscoops that the situation hasn’t changed.
We can only speculate, but it would seem that the original buyer has decided to allocate at least this one for resale. This might be one of the wildest flips we’ve ever heard of. We’ll report back if GMA provides any additional information on how the deal works.
How US-Legal Is It?

One last note for American buyers: importing it comes with a caveat. The car only qualifies under the “Show or Display” exemption. The silver lining is that Gordon Murray himself will assist with the necessary paperwork, according to the auction listing.
“Gordon Murray will assist with the necessary steps to have the S1 LM added to the approved list for this eligibility,” the RM Sotheby’s listing reads. “It remains the buyer’s responsibility to pay all applicable import duties, tariffs and taxes, as well as any costs associated with federalizing the vehicle, if that is their preference.”
