2026 Porsche 911 GT3 loses its top with new S/C variant that is the second most expensive Porsche at more than $500,000

Porsche has unveiled the 911 GT3 S/C, the first-ever fully-automatic convertible version of its highly-focused, naturally-aspirated GT3 model.

Powered by the same 4.0-litre (375kW/450Nm), horizontally-opposed, six-cylinder engine as its lightweight hardtop 911 GT3 S/T sibling, the new car boasts a 9000rpm rev ceiling with power going to the rear wheel only via a short-ratio, six-speed manual gearbox.

A pure-two-seater, the GT3 S/C’s bonnet, wings and doors are carbon-fibre and the 911 S/T’s carbon anti-roll bars and shear plate are carried over.

Other weight-saving measures include the ‘Porsche Ceramic Composite Brake’ (PCCB) package (claimed to be 20kg lighter than cast iron brakes), centrelock magnesium rims (20-inch fr / 21-inch rr) saving nine kilograms of unsprung mass, magnesium ribs and lightweight actuators in the automatic roof and a compact 40Ah lithium-ion battery, the latter saving a further 4.0kg.

The less is more approach continues inside with lightweight door panels incorporating carbon-fibre pull handles, carbon shell seats and even lightweight carpeting.

That said, the interior is full-leather including the sun visors and A-pillar trim. The seat centre panels are finished in perforated hide as is the steering wheel.

Resulting kerb weight is a relatively trim 1497kg which Porsche said is “only about 30kg more than the 991-generation 911 Speedster."

Relative to the previous gen GT3 the S/C’s ‘boxer’ engine features more aggressive cams from the 911 GT3 RS, flow-optimised individual throttle bodies and specific oil coolers.

Claimed 0-100km/h acceleration is 3.9 seconds with maximum velocity pegged at 313km/h.

Under the heading of interesting details, the soft top can be opened or closed in 12 seconds at speeds of up to 50 km/h, the digital tachometer display can be rotated so its 9000rpm limit is positioned at 12 o'clock and an optional ‘Street Style Package’ adds a distinctive colour, materials and graphics treatment.

Street Style exterior highlights include ‘PORSCHE’ lettering on the car’s sides in ‘Pyro Red’, wheels finished in slate grey ‘Neo’, brake calipers in ‘Victory Gold’ and tinted HD-matrix headlights.

Cabin upgrades include ‘Adaptive Sports Seats Plus’ with centre panels upholstered with four-tone braided leather, while the steering column, seat console, air vents (including the slats!), inner sill trim and fuse box cover are also trimmed in leather.

Introducing the 911 GT3 S/C, Porsche Head of GT Cars Andreas Preuninger said, "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.

"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," he said.

The 911 GT3 S/C is a permanent addition to the German brand’s local line-up (rather than a limited edition, as per the GT3 S/T) with pricing set at $588,500, before on-road costs. The Street Style package adds $58,670.
