The best Porsche ever? 2025 Porsche 911 GT3 supercar updated to retain heroic naturally aspirated engine, joined by street-focused Touring version but is it better than a Ferrari or McLaren?

The formula stays the same, but the specifics have been tweaked for one of Porsche’s most-loved cars, the 911 GT3.

Updated and launched alongside its road-focused, wingless Touring Pack version for the first time simultaneously, the 2025 Porsche 911 GT3 retains its 4.0-litre naturally aspirated flat-six petrol engine, but has undergone some mechanical tweaks.

As well as coming with ‘more extensive standard equipment’ and some styling and aerodynamic changes, the GT3 is also now more expensive than before.

With pricing starting from $446,700 before on-roads for the 911 GT3, with or without the Touring Package, the supercar’s asking price represents a $29,300 increase over the pre-update version ($417,400).

While changes have been made to the drivetrain including revised cylinder heads, camshafts borrowed from the GT3 RS, upgraded throttle valves and oil coolers, the engine’s power remains the same at 375kW, although torque drops from 470Nm to 450Nm.

Part of this could be down to “significantly stricter exhaust standards” that mean Porsche has had to include more emission controls including two particulate filters and four catalytic converters. Porsche promises that despite this the GT3’s 9000rpm scream remains formidable.

When fitted with the seven-speed dual-clutch PDK gearbox, the GT3 reaches 100km/h in 3.4 seconds and can top out at 311km/h (it’s 3.9 seconds and 313km/h with a six-speed manual). Both transmissions have been tweaked to feature a final drive ratio that is eight per cent shorter.

Changes inside the cabin including new bucket seats, a rear seat option for the Touring version for the first time, and an optional roll cage mean the GT3 can be properly customised for road or track.

The Weissach package (for $47,530) adds elements like an anti-roll bar and coupling rods made from carbon-fibre reinforced plastic (CFRP) as well as the roof, side plates of the rear wing, exterior mirror top shell, mirror triangle and the air blades all composed of CFRP.

A Lightweight package ($71,120) includes similar CFRP elements, painted in body colour, but adds magnesium forged wheels and the lightweight door panels.

A Club Sport package for track driving is available at no cost, with a steel roll cage in the rear, a six-point harness for the driver and a hand-held fire extinguisher.

Available to order in Australia from the end of the year, specific standard features include a lifting system on the front axle (for traversing speed bumps and ramps), ParkAssist with a reversing camera, DAB radio and the Light Design Package.
