In the latest of episode of Hagerty “The Driver’s Seat” series, Henry Catchpole explores the engineering and design philosophy behind the Porsche 911 GT3 S/C in an exclusive conversation with Porsche’s GT division head.
At first glance, the idea of a GT3 Cabriolet seems unusual—combining track-focused engineering with open-top driving comfort. Yet the Porsche 911 GT3 S/C aims to prove the pairing works in practice. Porsche’s GT boss Andreas Preuninger explains that customer demand for a more usable GT convertible helped drive the concept.
Interestingly, the concept began as an experiment—combining a GT3 and a Carrera Cabriolet prototype. The result impressed engineers with its balance and driving enjoyment, requiring almost no suspension changes from the GT3 Touring.
Power comes from a 4.0-liter naturally aspirated flat-six producing 502 hp and revving to 9,000 rpm. It remains driver-focused with a manual gearbox, no rear seats, and extensive lightweight materials including magnesium wheels, carbon ceramic brakes, and carbon fiber components, keeping weight under 1,500 kg despite the roof system.
The S/C is designed less for track dominance and more for immersive, open-air driving. Without a fixed roof, the GT3’s signature engine sound becomes even more visceral, enhancing the emotional connection.
