There are plenty of Porsche 911 variants that make sense instantly. The do-
everything Carrera T coupe. The autobahn-storming Turbo S. The raw-yet-elegant GT3 Touring – all cars that are very easy to understand.
The new 911 GT3 S/C is a bit more provocative. It is, in essence, a GT3 cabriolet: naturally aspirated, manual-only, rear-wheel drive, and now fitted with a fully automatic soft- top that you can drop in just 12 seconds.

For a certain kind of Porsche enthusiast, the combination will be enough to cause offence. Isn’t a GT3 supposed to be serious? Convertibles, they’ll suggest, are not.
Yet, after driving the GT3 S/C hard across Germany’s Swabian Alb region, I’m not buying that argument. In fact, I think the S/C might be the most emotionally satisfying modern GT3 yet.
What exactly is the GT3 S/C?
This is the first GT3 based on the 911 cabriolet format, and the sole drop-top variant in the current 911 GT range.
But it’s not the first open GT3. First came the 991-generation Speedster…and unlike that car, the S/C is not a limited-run special edition for collectors. This is a series production model that can be ordered on an ongoing basis.
That effectively means you can buy one of these for the next few years, until
European emissions laws turn the screws hard enough to force Porsche into adding some kind of CO2-saving device…like a turbocharger. Or a hybrid system.
Cars like this are an endangered species. The S/C is powered by a 4.0-litre naturally aspirated flat-six that can rev out to 9000rpm. The only gearbox is a six-speed manual with no option of the PDK automatic.
In Australia, the S/C is priced from $588,500 plus on-road costs, which means it sits in fairly serious territory even before your imagination gets the better of you on Porsche’s famously involving configurator.
Go on then. What are the headline numbers?
That’s the thing: while the S/C is an undoubtedly quick car, among top-end 911s it’s actually more about the experience than the stats. Still, you can rattle off 375kW and 450Nm to your mates, along with a 3.9-second 0-100km/h time. Top speed? 313km/h.
The thing is that in 2026, none of those numbers are especially outrageous, and a number of EVs could embarrass the S/C off the line, not to mention Porsche’s
recently-refreshed 911 Turbo S. To worry about that would be to miss the point
entirely.
Frankly, the more interesting number here is 1497kg: Porsche says the S/C is the
lightest open-top 911 in the current lineup. It’s lighter than several hot hatches, in fact. Going manual over PDK saved 17kg, and carbon-fibre doors, guards and anti-roll bars play their part…as do magnesium alloys, which you can lift with one hand.
Convertibles add heft, which is why Porsche took the standard Carrera cabriolet’s drop-top and swapped the ribs out for magnesium items. It’s still powered, though, and you can open it at up to 50km/h on the go.
Isn’t the GT3 meant to be… hardcore?
Yes, it is. The GT3 badge carries a seriousness among those in the know. And
cabriolets? Well…they’re usually seen as a choice for people more interested in
being seen than driving hard. But the S/C is more than a regular 911 cabriolet with a GT3 engine and some sexy wheels.
Porsche has given the S/C plenty of toys from the top shelf: double-wishbone front suspension for the first time in an open-top 911, anti-dive geometry to keep the nose settled under braking, aero-shaped front control arms that channel air towards the brakes, and the same suspension as the GT3 coupe.
It also gets carbon-fibre anti-roll bars and a carbon-fibre rear shear plate from the 911 S/T. Ceramic brakes measure a massive 410mm up front and 390mm at the rear, and it nabs staggered Michelin Pilot Sport Cup 2 tyres, with 20-inch wheels at the front, 21s at the rear.
In short, Porsche has gone to real engineering effort to make sure the S/C drives like a GT3 first, and a cabriolet second.
What’s it actually like to drive?
It’s pretty spectacular. All that engine dominates first impressions. While there’s no missing the exhaust, what you hear with the roof down is plenty of induction sound; the mechanical hardening of the flat-six as revs climb; and a wild stretch out to 9000rpm where the engine wails like a banshee.
The six-speed manual is central to the experience, of course. The short-shifter feels mechanical and has enough resistance to feel serious, but not tiresome. An auto-blip function lets you nail every downshift…or you can turn it off and try your hand (foot) at heel-toeing.
For me, the best part is the consistency of the controls. The throttle is insanely
precise, the steering finely detailed. The brakes inspire confidence. And the damping is a revelation: you’d expect a car like this to be overly stiff, but it isn’t.
While the S/C is firm, it rounds off broken-up surfaces in a way that seems almost unfair for something as focused as this.
Is this a $600K-plus car on the inside?
Yes and no. You can tell that the money has been spent on the mechanicals, though you’re hardly slumming it inside the GT3 S/C, which features extended leather trimming as standard and one of the best-executed cabin designs on sale.
The way the 911 continues to relegate cabin tech to a secondary role remains novel in 2026. There is a digital instrument cluster, but it can recreate classic five-dial Porsche layouts and has a Track Screen mode that cuts the display back to essential information.
The central touchscreen is properly embedded into the dashboard rather than
sticking out like an iPad from Temu. The steering wheel is round. The gear shifter is exactly where it should be. Key controls remain easy to access.
The catch is seat choice. The optional carbon-fibre bucket seats look fantastic and suit the car, but they don’t fit every frame. I found them too narrow around the legs and not especially comfortable over distance. Getting in and out is awkward, which is kind of amusing in the way expensive sports-car inconveniences can be…until you have to do it in front of a packed café.
For that reason alone, the cushier, ventilated 18-way Adaptive Sport Seats Plus
deserve your serious consideration.
Would we buy one?
Definitely. While I think I’d probably still end up in a GT3 Touring, the times we live in complicate things, and we think the S/C adds something to the experience that a coupe can’t match.
The open roof of the S/C makes this car feel more alive, without making it feel less serious. You hear more of the flat-six, but also more of everything else: wind, birds, people, tyres, the air moving around the car, the landscape. In a lesser car, that would sound like fluff. In the S/C, it’s a big part of the reason why you’d do it.
If this really is one of the last periods of time in which Porsche can build a naturally aspirated, manual GT3 without turbocharging or hybridisation, getting as close as possible to the experience is insanely appealing. And the S/C gives you exactly that.
