- The S/C is essentially a 911 GT3 Convertible in name only.
- It features a fully automated fabric roof that operates in 12 seconds.
- While it’s heavier than the 911 Speedster, the difference is minimal.
Porsche has seen a decline in sales over the past three years, yet the 911 continues to stand out. In 2025, the model achieved a record delivery of 51,583 units, with this year already showing a promising uptick of 22 percent in deliveries compared to the same period last year, totaling 13,889 cars by March.
Looking forward, Porsche is expanding the 911 lineup with new variants to enhance its market appeal. The GT3 S/C (Sport Cabriolet) takes inspiration from the Speedster but is not its direct successor. The key distinction is that this model is Porsche’s first GT3 variant with a fully automated roof.
This means you don’t have to get out of the car to operate the roof. With just a button press, the fabric top opens or closes in about 12 seconds, provided you’re not exceeding 31 mph (50 km/h). Another button activates a wind deflector that deploys or retracts in just two seconds.
The added complexity of the roof mechanism results in a small weight increase, with Porsche claiming the GT3 S/C is approximately 66 pounds (30 kilograms) heavier than the Speedster. The U.S. model weighs in at 3,322 pounds, while the European version is at 1,497 kilograms. Notably, this is the first 911 convertible equipped with a double-wishbone suspension in the front, with chassis tuning aligned closely to the 911 GT3 coupe, featuring the Touring Package.
To maintain a low weight, Porsche utilizes carbon-fiber-reinforced plastic for the hood, fenders, doors, and rear anti-roll bar. The connecting links and the underbody panel beneath the rear axle are also made from CFRP. Additionally, standard magnesium wheels and ceramic brakes contribute to reducing weight. The convertible’s frame incorporates magnesium for further weight savings.
For further weight reduction, optional lightweight bucket seats with CFRP shells can be installed. The GT3 S/C accommodates only one passenger since rear seats have been removed, making it the sole 911 convertible designed exclusively as a two-seater. Naturally, you’ll likely prefer driving with the roof down to enjoy the sound of the naturally aspirated 4.0-liter flat-six engine revving up to 9,000 rpm.
The powerful boxer engine generates 502 horsepower and 331 pound-feet (450 Newton-meters) of torque, matching the GT3 coupe. It accelerates from 0 to 60 mph in 3.7 seconds and reaches 62 mph (100 km/h) in 3.9 seconds. The GT3 S/C can reach a top speed of 194 mph (313 km/h).
Unlike the Speedster, which was limited to 1,948 units as a nod to Porsche’s production start year, the new GT3 S/C is not a limited edition. It is available solely with a manual transmission, similar to the Speedster, unlike the GT3 coupe, which offers both manual and dual-clutch options.
Priced at $275,350, including destination charges, the 911 GT3 S/C represents a substantial saving over a similarly equipped coupe, which would cost over $308,000—an 11 percent discount for opting for the convertible. This doesn’t consider additional features like carbon-fiber fenders and doors from the 911 S/T.
The 911 GT3 S/C is set to become available at Porsche dealers across the U.S. this fall.
