Porsche Just Built a Roofless GT3… and Kept It Manual
by AutoExpert | 15 April, 2026
The 2027 911 GT3 S/C doesn’t try to win everyone over, and that’s exactly what makes it interesting. At first glance, a roofless GT3 feels like a contradiction. But the more you think about it, the more it comes across as a deliberate shift, not a mistake.
It leans on a familiar recipe. Like the 2023 911 S/T, it pulls in GT3 RS hardware and pairs it with a six-speed manual. No PDK, no obsession with lap times. Just a car that asks you to be part of it, not just along for the ride.
The design pulls in plenty from the RS. You get composite fenders flowing into slash-cut doors, a dual-vented carbon hood, wide rear arches, and a small Gurney lip instead of a fixed wing.
The engine sticks with the GT3 formula. A 4.0-liter naturally aspirated flat-six with RS cams, putting out 502 hp (510 PS). That’s a bit under the GT3 RS at 517 hp (525 PS), but it still spins to 9,000 rpm. Manual only.
Performance is unchanged on paper. 0 to 60 mph (97 km/h) takes 3.7 seconds, and top speed is 194 mph (312 km/h), matching the GT3 Touring.
Weight is surprisingly close to the coupe. The S/C comes in at 3,322 lbs (1,507 kg), compared to 3,239 lbs (1,469 kg) for a Touring. That’s an 83 lb (38 kg) gap, much smaller than the 185 lb (84 kg) penalty seen on a Carrera S Cabriolet. Porsche keeps it tight with carbon panels, PCCB brakes saving 44 lbs (20 kg), and magnesium center-lock wheels cutting another 19 lbs (8.6 kg).
Underneath, it’s still a full GT3. Double wishbone front suspension, a carbon fiber rear anti-roll bar, and no shortcuts in the chassis.
Inside, it strikes a balance. You can go with carbon bucket seats that tilt forward for rear access or stick with the standard sports seats if you want something easier to live with. There’s even the option of storage boxes behind the seats. The wheel stays simple and round, and it still uses a key to start.
Unlike the S/T’s 1,963-unit run, this one is not limited. Porsche instead offers things like the Street Style Package. That brings red graphics, Slate Grey Neo finishes, Victory Gold brake calipers, and a red plaid interior. It’s a bold look, to say the least.
There’s also a matching Porsche Design watch, exclusive to S/C buyers, with a titanium case and details inspired by the car.
Pricing starts at $275,350. That’s more than the $238,150 GT3 and GT3 Touring but still under the $286,650 Turbo S Cabriolet.
It’s not chasing lap times or trying to outdo the GT3 RS. The idea is simpler. Keep the same character, just take the roof off.
