Homologation rules for racing have resulted in some of the world’s greatest sports cars, and sitting high on the list is the Porsche 911 GT1 Straßenversion, the homologation special for the 911 GT1 race car that ran in the BPR Global GT Series during the 1990s.

The U.K.’s Tuthill, a company known for modifying Porsche 911s, decided the time was right to build a tribute to the 911 GT1 Straßenversion, and the resulting car is known as the GT One. It made its debut at the recent 2024 Monterey Car Week and will only be offered to 22 customers.

Unlike the 911 GT1 Straßenversion, which was derived from a race car and thus, according to Tuthill boss Richard Tuthill, was somewhat compromised for the road, the GT One has been fully developed with road use in mind.

“The FIA GT1 class enabled manufacturers to create stunning race cars,” he said in a statement. “We have taken the best bits but focused on producing a wonderful road car.”

Tuthill hasn’t revealed what chassis serves as the basis of the GT One, but the styling is reminiscent of the 993-generation 911, which was also the case for the 911 GT1 Straßenversion. The unique details are the work of independent designer Florian Flatau, who has previously worked with famous Porsche tuner Singer. Flatau was also responsible for Singer’s wild All-Terrain Competition Study, which was a collaboration between Singer and Tuthill.

The GT One’s body is all carbon fiber, which helps to get the weight down to less than 2,645 pounds, per the company. But despite the lightweight ethos, there’s no skimping on luxury in the cabin, which features bespoke controls and only the one digital screen serving as the gauge cluster.

Power comes from a mid-mounted flat-6 engine. The 4.0-liter engine delivers 500 hp as standard or more than 600 hp with available forced induction. Buyers will also have the choice between a 7-speed dual-clutch automatic transmission or a conventional manual.

Tuthill plans to build 22 examples, with the build time claimed to be around 3,500 hours. Availability and prices haven’t been mentioned.
