Porsche has traditionally offered Cabriolet versions of the 911 only for its more civilized and comfort-oriented variants of the sports car icon. A drop-top GT3 would arguably make no sense to most purists, as a dedicated track tool requires maximum structural rigidity and a low drag coefficient while fulfilling high safety standards – qualities an open roof does not support.
However, that is only half the truth. Enthusiasts are well aware that the Zuffenhausen-based company has already built GT3-derived open variants, namely the 911 Speedster of the 991.2 generation. That model was limited to 1,948 units to celebrate the 70th anniversary of the iconic brand.
The newest addition to the model family, the 911 GT3 S/C, follows in the footsteps of this purist driving machine but offers a more civilized approach. While its predecessor in this special lineage featured a lower windshield and a manual lightweight fabric top that was stowed in a dedicated compartment beneath the large “double bubble” carbon-fiber rear lid, the GT3 S/C features a more comfort-oriented, albeit heavier, fully automatic soft top. By using magnesium surface elements, the roof achieves a coupe-like silhouette and aerodynamic efficiency, opening or closing in just twelve seconds at speeds up to 50 km/h.
A featherweight compared to the other 911 Cabriolets
To prevent a compromised driving feel due to increased weight, Porsche combined GT3 and S/T components in its new open two-seater. This does not just make it a featherweight in comparison to the less sporty 911 Cabriolets but also gives it a unique appearance. For instance, the hood, fenders, doors, and roll bars made of CFRP were carried over from the S/T to compensate for the weight added by the canvas top. Another weight saving measure is the inclusion of magnesium wheels, which had been reserved for the S/T version until now. Clocking in at 1,497 kilograms, it is only 30 kilograms heavier than the more hardcore 911 Speedster and more than 80 kilograms lighter than a base spec Carrera Cabriolet. It even undercuts the 911 Carrera 4 GTS Cabriolet by 170 kilograms, which makes a world of difference in terms of driving dynamics.
At the heart of the new 911 GT3 S/C lies the 4.0 liter naturally aspirated flat-six already known from the other 992 GT3 versions, which has been reworked to meet current emissions standards using two particulate filters and four catalytic converters. Porsche claims to have preserved the emotional soundtrack that becomes significantly more intense with the top down. The engineers also revised the cylinder heads, while sharper camshafts sourced from the 911 GT3 RS ensure an even more visceral power delivery in the upper rev range. This is complemented by flow optimized individual throttle valves and improved oil coolers.
Delivering 510 hp, the engine is mated to a six speed GT manual transmission featuring the same short final drive ratio as the 911 S/T and the standard GT3. This focused setup allows the 911 GT3 S/C to sprint from zero to 100 km/h in 3.9 seconds and reach a top speed of 313 km/h. But purists will care more about the engaging character of the car, provided by the standard stick-shift, than these numbers. Furthermore, this model marks the debut of the double-wishbone front axle in an open-top 911. With a chassis tuning that matches the 911 GT3 with Touring Package and high-grip sport tires, the car is claimed to offer a level of handling and precision on winding roads that was previously thought impossible for a convertible.
Legacy Name, New Identity
Porsche has already confirmed a base price of 269,000 euro for this newest non-limited version. Considering the elevated price point, the S/C designation is quite ironic in hindsight. During the late seventies and early eighties, the company used the SC (Super Carrera) badge for the core of its 911 G-Series lineup. While the original SC was designed to be the quintessential, widely accessible 911 of its era, the new S/C is positioned as a highly exclusive performance machine higher up in the Porsche hierarchy.
It’s no surprise that the company exclusively offers its new S/C customers a special watch by Porsche Design, allowing them to carry the aesthetics of the car on their wrist. An optional “Street Style” package for the 911 GT3 S/C is available for an additional 27,941.20 euro. This package includes striking Pyrored graphics on the fenders and Slate Grey Neo wheels with Victory Gold brake calipers. The front is accented by darkened HD-Matrix headlights and body-colored airblades. Inside, the cabin features bicolor leather in Slate Grey and Guards Red, with seat centers made of a four-color braided leather. A notable detail is the darkened gear lever featuring an open-pore laminated wood ball, a nod to the legendary Carrera GT and the brand's racing heritage.
