Porsche has expanded its GT line-up with the introduction of the 911 GT3 S/C, an open-top variant that blends the core elements of its track-focused models with a more immersive driving experience.

For the first time, the GT3 is offered with a fully automatic convertible roof, allowing drivers to experience the naturally aspirated flat-six engine without a fixed roof. The S/C draws inspiration from previous limited-run models such as the 911 Speedster and 911 S/T, but differs in being a regular production model rather than a strictly capped release.

At its core is a 4.0-litre naturally aspirated six-cylinder engine producing 375kW and 450Nm, paired exclusively with a six-speed manual transmission. The engine revs to 9000rpm and delivers a 0–100km/h time of 3.9 seconds, with a top speed of 313km/h.

A focus on weight reduction remains central to the GT3 S/C’s design. The body incorporates carbon-fibre panels for the bonnet, doors and guards, while magnesium components are used in areas such as the roof structure and wheels. The result is a kerb weight of 1497kg, only slightly heavier than previous lightweight-focused GT variants.

The exterior design carries over elements from the 911 S/T, including distinctive body panels and a black windscreen surround. A retractable rear spoiler with a Gurney flap and revised front-end aerodynamics contribute to both performance and visual identity, while matrix LED headlights allow for larger air intakes at the front.

The soft-top roof can be opened or closed in around 12 seconds at speeds of up to 50km/h, and features integrated magnesium supports to maintain a coupe-like silhouette when raised. An electrically operated wind deflector is also included to improve comfort during open-top driving.

Inside, the GT3 S/C adopts a minimalist, driver-focused layout. It is configured as a strict two-seater, with lightweight materials used throughout, including simplified door panels and carbon-fibre detailing. Standard Sports Seats Plus are fitted, with optional lightweight bucket seats available. A digital instrument display includes a track-focused mode that prioritises key performance data.

Porsche also offers a Street Style Package, adding contrasting exterior graphics and bespoke interior finishes for further personalisation.

Priced from $588,500 before on-road costs in Australia (the Street Style package is priced from $58,670), the 911 GT3 S/C is positioned as a niche offering within the 911 range – one that prioritises driver engagement through a combination of manual transmission, lightweight construction and open-air performance.
