One-off GMA T.50 supercar may be unveiled at Pebble Beach

Earlier today, Gordon Murray Automotive announced its plans to reveal a new supercar at the 2025 Goodwood Festival of Speed. It is likely to be the T.33S, which was showcased two years ago.

However, it’s not the only GMA supercar that will be unveiled this year. Rumors suggest that a one-off model is in the works, and it will reportedly be based on the T.50. We’ve learned that the T.50-based one-off could break cover at Pebble Beach.

Exact details of the new one-off aren’t known. But, if we were to hazard a guess, it might be as simple as a unique spec or a slightly modified version of the T.50.

The GMA T.50 made its global debut in 2020. It was the company’s first product, which, despite its $3 million price tag, was a resounding success. The T.50 is an old-school analog supercar with a naturally aspirated engine mated to a manual gearbox.

The GMA T.50 is powered by a 3.9-liter, naturally aspirated V12 engine built by Cosworth. The engine produces 654 hp @ 11,500 rpm and 344 lb-ft @ 9,000 rpm. It is the highest-revving naturally aspirated road car engine ever built, revving to 12,100 rpm!
