One of only five examples of the Gordon Murray Automotive S1 LM V12, a road-legal love letter to the golden age of endurance racing, is heading to auction — and the price tag could easily top $20 million.

RM Sotheby’s will handle the sale later this month, and in a fitting twist, proceeds will go to charity. But this is no ordinary millionaire’s toy. As Shelby Myers, global head of private sales at RM Sotheby’s, puts it:
“S1 LM Chassis #1 offers a unique opportunity to collaborate with the original creator and help write the next chapter in automotive history.”
That creator, of course, is Gordon Murray, the legendary mind behind the McLaren F1, Brabham BT46B, and Mercedes SLR McLaren. The S1 LM is his latest opus — and perhaps his most personal.

A Modern Echo of Le Mans Glory
The S1 LM was conceived as a modern homage to the Le Mans–winning McLaren F1 GTR, blending the purity of old-school engineering with cutting-edge precision. The car retains the F1’s three-seat layout, with the driver perfectly centered, and a six-speed manual gearbox — a deliberate nod to the analog era that built Murray’s reputation.

But it’s the engine that steals the show. The Cosworth-built 4.0-liter V12 has been reimagined, stretched to 4.3 liters, and fine-tuned to deliver more than 700 horsepower while revving beyond 12,000 rpm. That’s motorcycle-level ferocity wrapped in carbon fiber elegance — and it all happens in a car that weighs less than one ton.
The proportions are spot-on: a long, low nose, a tightly sculpted tail, and a functional rear wing that whispers Le Mans pedigree without shouting it. Inside, the cabin is minimalist but exquisite — every surface purposeful, every control machined with Murray’s trademark precision.
A Car Born from Resilience
For all its engineering brilliance, the S1 LM’s greatest story might be human. Murray developed the car while undergoing treatment and recovery from cancer — a journey that gave the project an emotional depth beyond horsepower and lap times.
“The amount of effort and focus you have to put into a brand-new car is so great that you don’t have time to think about anything else,” Murray shared recently. “Designing this vehicle helped me get through it all. The S1 LM is special for all those reasons.”

The S1 LM, then, isn’t just a supercar. It’s a statement — of survival, of design purity, and of the kind of mechanical passion that doesn’t fade with time.
The Next Chapter
As RM Sotheby’s prepares to bring Chassis #1 under the hammer, the sale feels less like a transaction and more like a passing of the torch. Whoever wins the bid won’t just own a car; they’ll own a slice of living automotive history — one forged by a man who turned recovery into creation, and once again reminded the world what true performance looks like.
If ever there were a machine worth $20 million, this might just be it.
