2025 Porsche 911 GT3 update revealed with price and specs for Australia

Yesterday at 12:30 PM

The 2025 Porsche 911 GT3 has been given a facelift – with updated styling, but reduced torque due to new emissions controls – ahead of Australian arrivals due in the second half of next year.

The GT3 does not inherit the hybrid technology added to Porsche’s regular 911 range, rather retains a 4.0-litre naturally-aspirated ‘flat’ six-cylinder engine capable of revving to 9000rpm.

However, strict emissions controls have seen torque drop from 470Nm to 450Nm – the lowest torque output in a 911 GT3 in nearly a decade – with power unchanged at 375kW.

Australian deliveries are due to begin in the second half of 2025, priced from $446,700 plus on-road costs – up $29,300 on the outgoing model.

That RRP applies to six-speed manual and seven-speed PDK dual-clutch automatic transmissions, as well as the regular GT3 and its wing-less GT3 Touring sibling – all no-cost choices.

For the ‘992.2’ generation GT3, the 4.0-litre engine gains revised cylinder heads, upgraded camshafts from the 992.1-series 911 GT3 RS, flow-optimised individual throttle valves, and new oil coolers.

It is fitted with pollution-control equipment to meet the latest emissions standards, with two petrol particulate filters and four catalytic converters.

Porsche has shortened the final drive ratio on both transmissions by eight per cent for improved acceleration on the move, though top speed takes a hit, from 320km/h to 313km/h in the manual, and 318km/h to 311km/h in the PDK auto.

The claimed 0-100km/h acceleration times of 3.4 and 3.9 seconds for the manual and PDK auto respectively remain unchanged, with the GT3 still rear-wheel drive.

For historical context, the latest 992.2-series GT3 has almost as much power (375kW vs 390kW), and is 0.2sec slower to 100km/h (3.9sec vs 3.7sec) than a 997.1-series 911 GT2 of 2009 – with a price $800 lower today, or $225,000 less when adjusted for inflation.

Under the skin, the updated 911 GT3 gains new teardrop-shaped trailing arms for the double-wishbone front suspension that is claimed to increase downforce within the wheel arch at high speeds, and improve brake cooling.

Derived from the GT3 RS, the front ball joints on the lower front trailing arms have been lowered to limit front-end dive – how much the nose drops under heavy braking – and increase stability when slowing from high speeds.

The dampers have been retuned for improved race-track performance, and the steering has been tweaked.

New lightweight aluminium wheels save more than 1.5kg each, Porsche says, while a new 40Ah lithium-ion battery cuts a further 4kg.

Available for the first time on the 911 GT3 is the Weissach package – previously an RS exclusive – which saves even more weight for a cool $47,530.

It includes components made from carbon-fibre reinforced plastic (CFRP) – the rear anti-roll bar, coupling rods and shear panel, as well as the roof, rear wing endplates, mirror caps and triangles, front air intakes, interior door handles, and door pockets.

Leather and Race-Tex synthetic suede upholstery are included with the Weissach pack – including a Race-Tex upper dashboard for the first time – while magnesium wheels that save a further 9kg, and a CFRP roll cage, are optional with this package.

In place of the Weissach pack, the GT3 Touring is offered with the $71,120 Lightweight pack, which adds a rear anti-roll bar, coupling rods and shear panel made from CFRP, a body-coloured roof, lightweight door panels, and magnesium wheels.

In six-speed manual examples, the Touring’s Lightweight pack also adds the shortened gear lever from the 911 S/T special edition, with a ‘Leichtbau’ plaque in front of it.

Available on winged GT3s is a no-cost Clubsport package – offered on examples with lightweight bucket seats – which adds a steel rear roll cage, six-point seat harnesses, and a fire extinguisher.

Porsche says that in its lightest form, the 911 GT3 weighs 1420kg – compared to 1418kg claimed for the lightest version of the outgoing 992.1 model.

Standard are 255/35 ZR20 front and 315/30 ZR21 rear sports tyres, with track-ready – but still road-legal – rubber available as an accessory.

New on the outside of the 911 GT3 are redesigned matrix LED headlights, which negate the need for lower LED daytime-running lights – creating space for larger air intakes in the reshaped front bumper, which gains a “re-contoured” front diffuser.

There are modified fins on the underbody to increase downforce, a revised rear spoiler lip, restyled rear diffuser, air inlets and engine cover, and new angled side plates for the wing.

Porsche has also tweaked the tail-lights in line with the changes to the standard 911 range.

The Touring version is available from launch for the first time, deleting the fixed rear wing and adding an extendable rear spoiler with a ‘tear-off’ edge and ‘Gurney flap’ lip.

It gains revised underbody fins to maintain the aero balance with the loss of the fixed rear wing, plus new badging on the rear decklid.

Rear seats are now offered on the GT3 Touring for the first time – as an option – inside the leather-trimmed interior.

Inside all GT3s is the option of revised carbon-fibre reinforced-plastic front bucket seats, with integrated side airbags, with powered height (but manual longitudinal) adjustment, and optional heating functionality.

Less extreme 18-way power-adjustable adaptive sports seats ‘plus’ are available in their place for drivers not planning track days.

The GT3 retains a rotary ignition switch – rather than adopting the 2025 Carrera’s push-button start – as well as the switchgear of the outgoing, pre-facelift 911.

However, it has not escaped the axing of its analogue tachometer, adopting a widescreen digital instrument cluster with a Track Screen that limits the content on the left and right side of the central digital rev counter, and includes a shift light.

Drivers can rotate the tachometer so the 9000rpm redline is at the 12 o’clock point – something not afforded by the analogue unit.

Compared to the standard equipment lists versions sold overseas, Australian-market GT3s gain a tyre fit set, broader range of colours for no cost, front-axle lift system, rear parking sensors and camera, Light Design Package, and digital radio.

A unique watch is available for GT3 customers, with a titanium case, yellow accents, and a dial said to have been inspired by the car’s instrument panel and wheel design.

The 2025 Porsche 911 GT3 is available to order now in Australia, ahead of the first showroom arrivals due in the second half of next year.
