"Tuthill's GT One Is a Tribute to the Baddest 911 There Ever Was

The UK-based company plans to make 22 examples of this homage to the Porsche 911 GT1.


After causing quite a stir when photos of a 911 GT1-esque car arriving at LAX went around on social media, UK firm Tuthill Porsche has released the GT One. It's a tribute to the Porsche 911 GT1 race car of the late 1990s with over 600 horsepower, a 2,645-pound curb weight, and a planned 22-car production run.

Tuthill Porsche is a little coy on what, exactly, the GT One is based on. (Or if it's based on anything at all.) The 1996 and 1997 911 GT1 used the front and center section of a production 911 mated to a unique steel tubular rear taken off the 962 prototype. Perhaps Tuthill is doing something similar here, because the GT One is mid-engined, and quite obviously not a 911 at the back.

What we do know is that its offered with a choice of 4.0-liter flat-sixes, either a high-revving 500-hp naturally aspirated flat-six like the 11,000-rpm screamer Tuthill developed for its 911 K, or a 600-plus-hp flat-six with "forced induction." Tuthill Porsche doesn't specify whether the engine is turbo or supercharged, but we have to imagine turbocharged, since people don't typically supercharge Porsche engines.

You can have either a manual, or in the case of the car seen here, a dual-clutch transmission. The GT One has bespoke double-wishbone suspension front and rear, carbon-ceramic brakes, and a full FIA-spec roll cage. Bodywork is all carbon fiber, naturally, and the design is the work of California based Florian Flatau, who's previously done work with Singer.

If you don't know Tuthill Porsche, you should. It's a long-time rally and restoration shop based in the heart of the UK's "motorsports valley," and it's recently branched out into work with Singer and building its own wild restomods.

Admittedly, the name is a bit odd, given that the 911 GT1 raced against the Toyota GT-One in 1998. It's also something of a departure from the philosophy of the original 911 GT1, which was a true homologation special. A road car because it had to be. Tuthill is quick to point out that the GT One is a road car first and foremost, though it may develop an aero kit for track driving."


Tuthill Porsche hasn't revealed pricing yet, but one imagines it's a lot, as is the way with these things. And hey, if you want a car that stands out among Porsche resto-mods, you could do a hell of a lot worse than this.

Porsche 917 Street Drive… What If?
Fifty years ago this weekend, a unique Porsche 917 left the Zuffenhausen factory—not for the track, but for public roads.

Driven by a passionate private owner and a small, dedicated Porsche team, it embarked on an extraordinary first journey, ending not locally but hundreds of miles away in Paris.

Today, the car still roams the roads of southern France, now U.K.-registered and recently restored—its original paint and interior intact. As its racing descendant thrives on track, the daring spirit behind that original road-going 917 still lives on, inviting the same question it did then: what if?

Porsche 963 RSP

4.6 liter twin-turbocharged V8 making up to approximately 680 hp
Hybrid system Bosch/Williams
800 volts
battery has an energy capacity of 1.35 kWh
An output of 30 to 50 kW is available in short bursts

Obviously, Porsche would have to work with Porsche Penske Motorsport to make the car a reality, and the team decided that Roger would be the car’s ideal owner. The name RSP are the captain’s initials, Roger Searle Penske.

Porsche Just Patented An 18-Cylinder Engine. It Looks Wild

Gas is back, baby. And Porsche's latest patent could support 9, 15 or even 18 cylinders.
A new patent from Porsche shows its engineers aren’t afraid to push the boundaries of automotive technology. The automaker submitted a filing for a new W-shaped, “space-optimized” combustion engine that depicts it with 18 cylinders—six per bank—but it could fit in an assortment of potential products.

According to the filing, the engine could “have a different number of cylinders.” That means Porsche could build engines with 9 or 15 cylinders—three banks of three or five—with a relatively short engine block.

Porsche W18 engine - CLOSER LOOK​
Let's take a closer look at Porsche's W18 Turbo engine patent!

Why are they working on a W18 engine now, right in the middle of their electric transformation?

What is so special about W-engines and where have we seen them before? What can we expect and what would it mean for current hypercars?
