Porsche 911 GT3 S/C: A Permanent Convertible Joins the Lineup

Porsche has introduced a new convertible version of its 911 GT3 sports car, designated the 911 GT3 S/C. The model features a fully automated soft top and extensive use of lightweight materials. It will be a permanent addition to the lineup rather than a limited edition. Pricing and technical specifications differ between global markets.

Model Overview and Availability

The 911 GT3 S/C is described as the first fully automatic convertible version of the GT3 model. According to Porsche, it will be a permanent addition to the model lineup and is not a limited-production vehicle. The vehicle is configured as a two-seater, with rear seats removed.

Market availability and pricing vary significantly between regions.

  • In markets such as Australia, the starting price is $588,500 before on-road costs, with first deliveries scheduled for later in 2026.
  • In the United States, the manufacturer's suggested retail price is $275,350 including destination charges. Deliveries are scheduled to begin in the fall, with sources citing various years including 2024, 2025, and 2027.

Powertrain and Performance

The vehicle uses the 911 GT3's 4.0-liter naturally aspirated flat-six engine.

  • Global Specifications: The engine produces 375 kW (502 horsepower) and 450 Nm (331 pound-feet) of torque, with a 9,000 rpm rev limit.
  • Transmission: Power is delivered to the rear wheels exclusively via a six-speed manual gearbox.

Reported performance claims include:

  • 0-100 km/h / 0-62 mph: 3.9 seconds
  • 0-60 mph: 3.7 seconds
  • Top Speed: 313 km/h (194 mph)

Lightweight Construction and Chassis

Porsche states the vehicle employs extensive lightweight construction, sharing principles with the limited-edition 911 S/T. The reported curb weight is 1,497 kg (3,322 lbs). Porsche notes this is approximately 18 kg more than the standard GT3 coupe, and about 30 kg (66 lbs) more than the 991-generation 911 Speedster.

Key Weight-Saving Components

  • Body Panels: Carbon-fiber reinforced plastic (CFRP) for the bonnet/hood, front wings/fenders, doors, and quarter panels.
  • Chassis Components: Carbon-fiber anti-roll bars and shear panel from the 911 S/T.
  • Brakes and Wheels: Porsche Ceramic Composite Brake (PCCB) system, claimed to be 20 kg lighter than cast iron brakes. Lightweight magnesium center-lock wheels (20-inch front, 21-inch rear) are reported to save 9 kg of unsprung mass.
  • Roof Mechanism: Magnesium ribs and lightweight actuators in the automatic soft top.
  • Battery: A 40Ah lithium-ion battery, saving 4 kg.
  • Interior: Lightweight door panels with carbon-fiber pull handles, carbon shell seats, special carpeting, and reduced sound insulation.

Chassis and Suspension

Porsche states the chassis tuning mirrors that of the 911 GT3 Touring model. The company notes the GT3 S/C is the first open-top 911 to use a double-wishbone front axle.

Exterior and Interior Features

  • Convertible Top: The fully automated fabric soft top can be opened or closed in 12 seconds at speeds up to 50 km/h (31 mph). A wind deflector deploys in approximately 2 seconds.
  • Aerodynamics: A retractable rear spoiler with a Gurney flap replaces the fixed rear wing of the GT3 coupe.
  • Interior: The cabin features full-leather upholstery, including on sun visors, A-pillar trim, and a perforated leather steering wheel. Seat center panels are also perforated leather. Standard seats are four-way adjustable Sport Seats Plus. Lightweight folding bucket seats with carbon-fiber shells are available as an option.
  • Instrumentation: The digital tachometer display can be rotated to position the 9,000 rpm limit at the 12 o'clock position.

Optional Street Style Package

An optional Street Style Package is available. In markets with the $588,500 base price, this package adds $58,670.

Reported package contents include:

  • Exterior: 'PORSCHE' lettering on the vehicle's sides in Pyro Red. Slate Grey Neo finish for the wheels. Victory Gold brake calipers. Tinted HD-Matrix headlights.
  • Interior: Adaptive Sports Seats Plus with center panels upholstered in four-tone braided leather. Additional leather trim on the steering column, seat console, air vents, inner sill trim, and fuse box cover. Red stitching, special tartan seat inserts, and a dark open-pore wood gear knob are also mentioned.

Executive Statement

"We have already learned with the 911 Speedster and the 718 Spyder RS just how well our high-revving naturally aspirated engine, a particularly dynamic chassis set-up and thorough lightweight construction combine to create a true driver's car without a roof."

Andreas Preuninger, Head of Porsche's GT Car Line, added: "For the first time, the 911 GT3 S/C uses the double wishbone front axle on an open-top 911. Combined with the particularly high-grip sports tyres and low weight, the car offers driving pleasure on winding roads that was previously virtually unheard of in an open-top car."

Background and Context

  • The "S/C" moniker revives a badge used on 911 models between 1978 and 1983, which historically stood for "Super Carrera." For this model, it is believed to stand for "Sports Cabriolet."
  • Porsche reported that 911 model line deliveries reached 51,583 units in 2025, which the company described as a record. For the first three months of 2026, the company reported 13,889 deliveries, an increase of 22% compared to the same period in the previous year.
  • In the U.S. market, Porsche stated the GT3 S/C's price represents an approximate 11% saving compared to a similarly equipped 911 GT3 coupe.
