Porsche 911 GT3 S/C: When the GT3 Becomes a Model Stronger than the 911

As summer approaches, Porsche surprised everyone by launching the 911 GT3 S/C. It has nothing to do with the 911 SC type G; no, this is the first-ever 911 GT3 convertible. A car that may seem like an aberration at first glance, but the engineers at Weissach have done an exceptional job making it one of the sportiest convertibles ever created. With this new variant of the GT3, the designation is increasingly approaching that of a standalone model.

The First GT3 Convertible

You may remember the Porsche 911 Speedster type 991, which only had the engine from the GT3, which was already exceptional! But this 911 GT3 S/C type 992 goes further as it is nothing less than a wild crossover between a 911 S/T and a GT3 Touring. Starting from a base of the 911 convertible, Porsche has grafted the naturally aspirated flat-six 4.0 engine with 510 horsepower and 450 Nm from the GT3, along with the chassis.

Unlike the S/T, the GT3 S/C does not have the 525 horsepower engine from the GT3 RS, but can we really criticize it for having only 15 horsepower less? Not really, as it does not prioritize pure performance but rather driving sensations. However, it does feature some exterior elements from the S/C, including magnesium wheels and front fenders with air extractors.

Relevant Weight Reduction Work

A convertible is generally heavier than an equivalent coupe. The absence of a rigid roof necessitates reinforcements in the bodywork, while the soft-top frame and electric motors also add weight. Porsche has worked on weight reduction: the hood, front fenders, and doors are made of carbon, while the wheels are made of magnesium. The brake discs are ceramic carbon, allowing for a weight saving of 20 kg, particularly in unsprung mass.

As a result, this 911 GT3 S/C weighs only 36 kg more than a GT3 Touring, bringing its weight to 1,497 kg. Most drivers should not notice 36 kg at the wheel. Moreover, 36 kg is sometimes close to the weight difference between two drivers in a car.

Thus, using the engine from the GT3 along with the six-speed manual transmission from the GT3 Touring, and with a very similar weight, the performance is identical to that of a manual GT3 Touring, achieving 0 to 100 km/h in 3.9 seconds and a top speed of 313 km/h. It may not be the fastest convertible from Porsche; a 911 Turbo S Cabriolet performs much better, but that is not the philosophy of this GT3 S/C. This GT3 S/C aims to engage its driver, and its strictly two-seat passenger, in an authentic driving pleasure: an engine that revs and needs to be pushed to extract its full essence, and a manual gearbox as the conductor.

Will the GT3 Name Soon Be More Important than the 911?

Now the question remains: what is the purpose of this GT3 S/C? This has sparked the most debate since the car's presentation. It is not more performant than a 911 GT3 Touring; the GT3 Touring could have become a bit more powerful even by integrating carbon elements like the hood, fenders, or doors, as it would also have experienced a weight reduction. It will also not be chosen as a cruising car in Monaco since it does not come with a PDK transmission; the GT3 S/C is available only with a manual gearbox. This is unfortunate because the GT3 in Monaco is often used for appointments like a city car elsewhere, as the GT3 has become an even more positional good than a 911.

By adding a convertible version bearing the GT3 badge, Porsche further solidifies the GT3 as a standalone model in the Porsche lineup. There is now the GT3, the GT3 Touring, the GT3 RS, and the GT3 S/C, which will not be a limited series. The GT3 name has become so strong that we no longer say Porsche 911 GT3 but simply GT3, which could ultimately harm the reputation of the GT3. We are now far from the homologation spirit of the 911 in competition, which was the essence of the GT3 that served to homologate the 911 in the GT3 category and contributed to the 911's reputation.

Regarding the price, this 911 GT3 S/C is listed at €276,500 (before an €80,000 penalty). An optional Street Style package is offered at €27,455, adding stickers on the body, wheels with a trim, specific upholstery, extended leather in the cabin, and leather air vent slats.
