Revealed: 2027 Porsche 911 GT3 S/C is a Mega Manual, Open-Top Driver’s Car

Merging the lightweight soul of the 911 S/T with the sensory brilliance of open-top motoring, the new Sport Cabriolet is a naturally aspirated masterpiece dedicated to the art of the drive.

In the pantheon of Germanic high-performance machines, few combinations are as evocative as a high-revving boxer engine paired with an open sky. Porsche has once again answered the call of the most ardent driving enthusiasts with the premiere of the 2027 911 GT3 S/C.

Standing, of course, for ‘Sport Cabriolet,’ this fresh model variant is an emotional love letter to visceral, analog engagement, offering the world-class mechanics of the GT3 line in a pure two-seater, open-top format.

The S/T Formula, Unplugged

The 911 GT3 S/C is a sophisticated hybrid of Porsche’s most revered driver-focused attributes. It borrows the uncompromising lightweight components from the limited-production 911 S/T and marries them to the legendary 4.0-liter naturally aspirated six-cylinder boxer engine.

To ensure the most connected experience possible, Porsche has designated the GT3 S/C as a manual-only affair. It is equipped exclusively with a short-ratio, lightweight six-speed GT Sport manual transmission. This singular focus on the three-pedal experience cements its status as a purist’s tool, reminiscent of the 2019 911 Speedster but without the production volume constraints.

Consistent Lightweight Construction

“We have managed to keep the weight of the 911 GT3 S/C particularly low at 3,322 lbs. despite the fully automatic top,” said Frank Moser, Vice President 911 and 718 model line. “The new 911 GT3 S/C responds to our customers' desire for sports cars that are particularly fun to drive. The exciting powertrain of the 911 GT3 comes into its own even more when driving without a roof, especially on winding country roads.

This featherweight figure is achieved through an extensive use of Carbon Fiber Reinforced Plastic (CFRP), which forms the hood, fenders, and doors – components directly inherited from the 911 S/T. The underbody panels and rear anti-roll bar follow suit in carbon fiber.

To further reduce unsprung mass, Porsche Ceramic Composite Brakes (PCCB) come as standard equipment, shedding over 44 lbs. compared to iron rotors. The 20-inch front and 21-inch rear center-locking wheels are forged from magnesium, saving an additional 19 lbs.

A Technical Masterpiece of Open-Air Engineering

Unlike its manual-roof predecessors, the GT3 S/C introduces a fully automatic lightweight top. Utilizing magnesium panels, the roof maintains the iconic 911 silhouette with a coupe-like curvature, free of visible bows. The hydraulic mechanism can cycle the top in 12 seconds, while an integrated electric wind deflector deploys in two seconds to preserve cabin serenity at high speeds.

Under the rear deck sits the heart of the beast: a 502 hp naturally aspirated engine capable of screaming to a 9,000 rpm redline. With sharper camshafts derived from the GT3 RS and flow-optimized throttle valves, the GT3 S/C surges to 60 mph in 3.7 seconds, reaching a top speed of 194 mph.

Bespoke Craftsmanship: The Street Style Package

For those seeking a more individualistic expression, Porsche Exclusive Manufaktur offers the Street Style Package. This ‘Director’s Cut’ option features Pyro Red decorative graphics, Victory Gold brake calipers, and a dark gear lever with an open-pore walnut shift handle.

The interior of the package is a showcase of precision, featuring four-color braided leather and an aesthetic that leans into modern color combinations. Owners can even complement their vehicle with a bespoke Porsche Design chronograph, featuring a winding rotor modeled after the car’s magnesium wheels.

Chassis and Arrival

Advanced suspension, combined with high-grip sport tires and the lightweight S/T chassis tuning, promises a level of agility rarely felt in a convertible.

“The arrival of the 911 GT3 S/C marks the first time an open-top 911 uses a double wishbone front axle,” said Andreas Preuninger, Porsche’s Director GT Cars. “In combination with the particularly high-grip sports tires and the low weight, the car offers driving pleasure on winding roads that has hardly been experienced with an open-top car before.

The 2027 Porsche 911 GT3 S/C is available for order immediately, with a starting MSRP of $273,000. U.S. Porsche Centers expect the first arrivals by the fall of this year. A significant number of features with this model become standard equipment that are otherwise optional on the 911 GT3:

- Lightweight package: $20,350- Magnesium Wheels: $17,840- Cabriolet (not optional, but value shown represents typical gap between coupe and       cabriolet variants): $14,000- Porsche Ceramic Composite Brakes: $10,370- Leather interior: $5,020

Adding those price equivalents to the MSRP of the 911 GT3 would bring the MSRP above $306,000. Considering that, the MSRP of the 911 GT3 S/C at 273,000 represents a discount of roughly 11 percent vs. the standard GT3 as-equipped. 

That figure also doesn’t account for the added carbon fiber parts that the S/C gains from the 911 S/T (fenders and door in carbon fiber), where options based pricing is not broken out.
