Porsche’s celebrated track-bred GT3 line has moved into a new generation with the long-awaited unveiling of the 992-series 911 GT3. The new model is described as “a highly athletic road car fit for high-performance driving on track balanced with the demands of everyday use”.

As with previous GT3 models, Porsche Motorsport has been heavily involved in the car’s development, this time in a bid to transfer “pure racing technology into a production model more consistently than ever before”.
To that end, the 992-gen GT3 features the traditionally high-revving naturally aspirated flat six in 4.0-litre form, with more power than ever. It also gets key aerodynamic and technological upgrades, the sum total of which has enabled the new model to set an impressive sub-7min lap time on the 20.8km Nürburgring Nordschleife. It also retains the option of a manual gearbox.

The 911 GT3 benefits from extensive exterior upgrades mostly aimed at enhancing aerodynamics and cooling. The most significant addition is a new ‘swan neck’ rear wing, adapted from that of the 911 RSR racing car. It’s manually adjustable and teamed with a prominent diffuser that can also be adjusted into a ‘Performance’ position to increase downforce. Porsche claims this mode is reserved “strictly for outings on the circuit”.
Other visible changes over a standard 992-gen 911 include a deeper front bumper with cleaner sides for further improved aero and a large central intake, plus further airflow-enhancing ‘nostril’ vents on the front bonnet. One GT3-specific optional extra is a roof made of exposed carbonfibre.
A number of customisation options via the Porsche Exclusive range are available, including carbon mirror tops, darkened headlights, a redesigned rear light cluster and Guards Red or Shark Blue paintwork for the edge of the wheel rims.

Like all 992s, the new GT3 is available solely in wide-bodied form. Dimensions have yet to be revealed, but despite the increased width and additional tech over its predecessor, the car has a claimed kerb weight of 1,418kg with the 6-speed manual gearbox and 1,435kg with the 7-speed dual-clutch PDK automatic.
The use of carbonfibre-reinforced plastic (CFRP) to make the front bonnet, lightweight glass, “optimised” brake discs and forged alloy wheels are listed alongside a lighter rear seat compartment cover as reasons for the model being only around 5kg heavier than its smaller predecessor.
Furthermore, a lightweight exhaust system, which saves 10kg, features “infinitely” adjustable flaps to ensure a “highly emotional sound experience” while still meeting the latest emissions and noise regulations.
The 4.0-litre naturally aspirated flat six is adapted from the track-only GT3’s and is “practically unchanged” from the unit to be used in the latest GT3 Cup racing car, according to Porsche.
Its 510hp is the same as the limited-run 911 Speedster and 10hp more than the 991.2-gen GT3 and allows the car to hit a top speed of 320kph (318kph with the PDK gearbox) – higher than the last GT3 RS. It can also cover 0-100kph in 3.4sec. The engine, as with the old GT3’s, is capable of revving to a dizzying 9,000rpm.
The 992 GT3 runs a substantially overhauled and race-inspired front suspension layout that uses double wishbones for the first time. The rear axle, meanwhile, is a modified multi-link set-up from the standard 992 with rear-wheel steering.
Braking is by 408mm discs on the front axle and 380mm on the rear. Porsche has yet to detail any optional carbon-ceramic system. The standard wheel choices are 20in at the front and 21in at the rear, with 255/35-profile Michelin Pilot Sport Cup 2 tyres at the front and 315/30 items at the rear. The 911 GT3 can also be had with optional, more track-focused Michelin Cup 2 R tyres.
2021 Porsche 911 GT3 interior
The new 911 GT3 shares almost all of its cabin architecture with ‘lesser’ 992s, albeit with kerb weight-reducing measures such as the obligatory removal of the rear seats and reduced sound deadening. However, there is no longer the option to delete the air conditioning to reduce weight further.
Alongside liberal use of Alcantara trim, sports seats and a half roll cage, there is one significant change over the standard 992 models: the gear selector. Rather than the shift-by-wire toggle switch, the PDK-equipped GT3 features a shifter that looks almost identical to the manual gearbox’s lever. Porsche GT boss Andreas Preuninger specified this feature because he prefers shifting via the centre console than using paddle shifts.
The other main new cabin feature is a ‘track screen’. When selected, this reduces the information displayed on the two digital displays located either side of the central rev counter to essential information needed on track, such as tyre pressures, oil pressure and temperature, water temperature and fuel level. A motorsport-derived shift assistant provides coloured bars to show revs on these screens, along with a shift-up light.
2021 Porsche 911 GT3 India launch
The previous-gen 911 GT3 was on sale in India and we can expect the new-gen model to arrive here as well, albeit in very limited numbers. However, a time-line for a launch has yet to be confirmed. When it arrives it’ll take on the likes of the recently updated Mercedes-AMG GT R.
