- Porsche has put the 911 Cabriolet’s convertible roof on the animalistic GT3, and enforced a manual-only policy. And we’re really excited about it. That’s essentially the whole story.
The new GT3 S/C is a fully open-top, naturally aspirated, manual-only, mass-production GT3 – and if that sentence doesn’t immediately make sense to you, the short version is that Porsche just built the most uncompromising droptop in its current lineup.
The formula is essentially a 911 S/T that swapped its fixed roof for a fully automatic soft top. The 4.0-litre flat-six – the one that screams to 9,000 rpm – carries over with 375 kW, paired exclusively with a short-ratio six-speed manual. No PDK. No option for PDK. You row your own, or you don’t get one.
At 1.5 tonnes, the GT3 S/C is only about 30 kg heavier than the 991-generation Speedster, which is a remarkable number for a car with a powered convertible mechanism.
That roof, incidentally, is more interesting than most press releases would have you believe. Unlike the 2019 Speedster – which used a manual soft top and a double-bubble tonneau – the GT3 S/C runs the 911 Cabriolet’s fully automatic mechanism, opening or closing in around 12 seconds at speeds up to 50 km/h.
The trick is maintaining the 911’s flyline with no visible structural elements beneath the fabric. Porsche says the closed profile is near-identical to the coupé’s silhouette, which also pays off aerodynamically. An electric wind deflector, operable up to 120 km/h, rounds out the open-air engineering.
Mechanically, you’re looking at the GT3 with Touring Package chassis setup – and notably, the double wishbone front axle marks the first time that arrangement has appeared on an open-top 911. The 0–100 km/h sprint takes 3.9 seconds, top speed is 313 km/h, and the engine gets revised cylinder heads plus the more aggressive camshafts from the GT3 RS for sharper response at the top end.
Inside, it’s a strict two-seater – no vestigial rear bench – with lightweight carpets, carbon-fibre door pull handles, and the rotary ignition switch that GT3 buyers have come to expect. The Track Screen mode strips the digital cluster down to essentials: tyres, oil, coolant, fuel. Shift lights flank the rev counter, and the entire display can be rotated so the 9,000 rpm redline sits at twelve o’clock. A small detail, but the kind that signals Porsche built this for people who actually use it.
Critically, the GT3 S/C is not a limited run. Unlike the Speedster, Porsche will build these for as long as the 992 generation runs. Which means the real question isn’t whether you can get one – it’s whether you can now justify not getting the manual-only, naturally aspirated, open-top GT3 that Porsche spent decades refusing to make.
