Porsche has taken its GT car formula in a bold new direction with the debut of the Porsche 911 GT3 S/C — the first-ever 911 GT3 variant to feature a fully automatic convertible roof.
Designed with a singular focus on driving engagement, this new model blends elements from the ultra-lightweight Porsche 911 S/T with the high-revving character of the Porsche 911 GT3.
At its core is a naturally aspirated 4.0-litre flat-six engine producing 375 kW (510 PS) and 450 Nm of torque, paired exclusively with a short-ratio six-speed manual transmission.
The result is a purist-focused driving machine capable of sprinting from 0–100 km/h in 3.9 seconds and reaching a top speed of 313 km/h — all with the option of open-air motoring.
Unlike previous open-top 911s, the GT3 S/C is configured strictly as a two-seater, echoing the philosophy of the Porsche 911 Speedster, but without the constraints of limited production. It also introduces a fully automatic soft top, engineered with lightweight magnesium components that allow it to open or close in around 12 seconds at speeds of up to 50 km/h.
Lightweight construction remains central to the GT3 ethos. Borrowing extensively from the 911 S/T, the GT3 S/C features carbon-fibre body panels, magnesium wheels, and a lithium-ion battery, helping keep kerb weight to just 1,497 kg — only marginally heavier than the previous Speedster. Standard Porsche Ceramic Composite Brakes (PCCB) further reduce unsprung mass while enhancing stopping performance.
Visually, the GT3 S/C stands out with its distinctive black windscreen surround, sculpted bodywork, and a retractable rear spoiler with a Gurney flap — a first for a convertible 911. The use of matrix LED headlights also allows for larger front air intakes, improving both cooling and aerodynamic efficiency.
Inside, the cabin reflects a motorsport-inspired minimalism. Lightweight materials, carbon-fibre trim, and a driver-focused layout dominate, while details such as a rotary ignition switch and configurable digital “Track Screen” reinforce its track-ready character. Buyers can also opt for carbon-fibre bucket seats and bespoke interior finishes.
Chassis-wise, the GT3 S/C adopts a double wishbone front axle — a first for an open-top 911 — paired with a GT3-derived suspension setup and high-performance tyres. This ensures that despite losing a fixed roof, the car retains the sharp handling and feedback expected of a GT-badged Porsche.
For those seeking additional visual flair, Porsche Exclusive Manufaktur offers a Street Style Package, adding bold exterior graphics, unique interior materials, and custom detailing options.
With the 911 GT3 S/C, Porsche has effectively created a new niche — an open-top, manual-only GT car that prioritises driver involvement above all else. It’s a compelling proposition for enthusiasts who want the rawness of a GT3 with the added thrill of roof-down driving.
