If there’s one thing Porsche knows how to do perfectly, it’s answering the prayers of automotive purists. Driving enthusiasts have long asked for a way to combine the spine-tingling howl of the GT3’s naturally aspirated 4.0-litre flat-six with the wind-in-your-hair thrill of a cabriolet. Heck, we’ve been asking for it since we got behind the wheel of the latest-generation Porsche 911 GT3 Touring in Manual. Well, today, those prayers have been answered with the new Porsche 911 GT3 S/C.
Taking the best parts of the revered 911 S/T and the razor-sharp GT3, this new open-top marvel is built explicitly for the driver. Best of all? It’s armed exclusively with a six-speed manual transmission.
Here is everything you need to know about Stuttgart’s latest drop-top masterpiece.

Heart of the Beast is a 9,000 RPM 4.0-litre Flat-6
The core of the 911 GT3 S/C sits the legendary 4.0-litre naturally aspirated boxer engine. Revised cylinder heads and aggressive camshafts borrowed directly from the 911 GT3 RS ensure razor-sharp throttle response as you climb towards the glorious 9,000 rpm redline. It produces 375 kW (510 PS) and 450 Nm of torque, taking the S/C from 0-100 km/h in just 3.9 seconds.
Because this car is all about emotional engagement, Porsche completely ditched the PDK automatic option.
The GT3 S/C comes exclusively with a lightweight, short-ratio six-speed manual gearbox. With the roof down, the flow-optimised individual throttle bodies and high-revving exhaust note will deliver an acoustic experience that simply can’t be replicated in a closed cabin.
It’s an Exercise in Featherweight Drop-Top Engineering
Convertibles are historically heavier than their coupe siblings, but Porsche went to extreme lengths to put the GT3 S/C on a strict diet.
Tipping the scales at a remarkably light 1,497 kilograms, it weighs only 30 kg more than the previous-generation 991 Speedster.
To achieve this, the engineers raided the 911 S/T parts bin. The bonnet, front wings, and doors are all crafted from carbon fibre, alongside a carbon-fibre shear plate and anti-roll bars. Unsprung mass is drastically reduced thanks to standard Porsche Ceramic Composite Brakes (PCCB) and lightweight magnesium centre-lock wheels (20-inch front, 21-inch rear). Even the battery is a compact 40 Ah lithium-ion unit, shaving off an extra 4 kg.
Roof and Aerodynamics are Refined
Unlike the Speedster with its manual tent-style top and double-bubble rear deck, the GT3 S/C uses the fully automatic lightweight roof from the standard 911 cabriolet line, but heavily modified.
Porsche used magnesium structural components for the roof frame, maintaining a flawless, coupe-like 911 flyline when closed.
The roof drops in just 12 seconds at speeds up to 50 km/h. To keep the airflow in check, there’s an integrated, electrically operated wind deflector that deploys in two seconds. Aerodynamically, the S/C borrows the front spoiler lip and rear diffuser from the current GT3, while adding a subtle Gurney flap to the retractable rear spoiler.
Cockpit Remains Pure a Two-Seater Sports Car
Inside, the GT3 S/C is strictly a two-seater affair. The cabin is stripped of excess, featuring lightweight carpets and door panels with carbon-fibre pull loops. Four-way adjustable Sports Seats Plus come standard, though hardcore enthusiasts can opt for carbon-fibre folding sports bucket seats.
In a nod to tradition, you won’t find a push-to-start button here; you fire up the flat-six using a rotary ignition switch to the left of the steering wheel. The digital instrument cluster includes a ‘Track Screen’ mode that condenses vital tyre, oil, and coolant data and even allows you to rotate the digital rev counter so the 9,000 rpm redline sits squarely at the 12 o’clock position.
