The 2026 Porsche 911 GT3 S/C has been unveiled, offering buyers the high performance of a GT3 model in a convertible body for the first time.
It can be ordered now ahead of first deliveries later this year, and is priced from $588,500 before on-road costs.
Like the Porsche 718 Spyder is to the Cayman GT4, the S/C borrows the 911 GT3’s powertrain and chassis – though the company says it shares its “lightweight construction” with the limited-edition 911 S/T, weighing in at under 1500kg.
Porsche’s classic layout continues, with the rear-engined S/C powered by the GT3’s 4.0-litre naturally aspirated flat-six petrol engine sending 375kW and 450Nm to the rear wheels – and the sole transmission available being a short-ratio six-speed manual.

However, Porsche says the S/C’s chassis mirrors that of the GT3 Touring, taking the track-oriented intensity of the pure GT3 down a touch.
In the spirit of the Speedster, the GT3 S/C is exclusively a two-seater – unlike other convertibles in the 911 Cabriolet lineup – but unlike the Speedster and the S/T, Porsche says the S/C won’t be a limited-production model.
Believed to stand for ‘Sports Cabriolet’, the S/C moniker revives an old badge used on 911s between 1978 and 1983, but at that point it translated to ‘Super Carrera’.
While convertible versions of coupe models tend to weigh substantially more – due to the additional bracing required – the 911 GT3 S/C tips the scales at 1497kg, or just 18kg more than the standard GT3, and around 30kg more than the 991-generation Speedster.
This is largely thanks to the extensive use of lightweight materials, with several body panels made from carbon-fibre, including the bonnet, doors, and quarter panels. A carbon-fibre anti-roll bar has also been taken from the 911 S/T.
A retractable rear spoiler with gurney flap – found on the S/T and GT3 Touring – replaces the 911 GT3’s fixed rear wing.
Lightweight magnesium centre-lock wheels feature, while magnesium has also been utilised in the mechanism for the fully automatic soft top which can lower in 12 seconds, at speeds of up to 50km/h.
Porsche has even gone so far as to replace the standard battery with a lithium-ion unit, saving 4kg, as well as fitting special carpet, interior door panels, and carbon-fibre door pulls – another carry-over from the S/T – all in the name of weight-saving.
Combined, this helps the 911 GT3 S/C achieve a claimed 0-100km/h time of 3.9 seconds, and a top speed of 313km/h.
“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 setup and thorough lightweight construction combine to create a true driver’s car without a roof,” said Andreas Preuninger, head of Porsche’s specialist GT department.
“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.”
For an additional $58,670, buyers will have the ability to option the S/C with a Street Style Package, which adds Pyro Red body accents, graphics, tinted HD-Matrix headlights, and wheels finished in slate grey Neo.
Inside, the Street Style Package adds red stitching and highlights, special tartan seat inserts, and a dark open-pore wood gear knob.
A pair of four-way adjustable Sport Seats Plus come standard in the S/C – upholstered in black leather – though lightweight folding bucket seats with a carbon-fibre rear shell can be optioned.
