All the facts on the new Porsche 911 GT3

The wraps are off the latest, fastest and most technically advanced 911 GT3 to-date

1w ago

After more than 20 years straddling the gap between road and racetrack, the 911 GT3 is still regarded as the benchmark driver’s car thanks to its unique motorsport drivetrains, advanced chassis technology and cutting-edge aerodynamic concepts. The seventh edition of the GT3 is now here with a host of improvements that promise to raise the bar for road-going sports cars once again.

The new GT3 uses the naturally aspirated 4.0-litre flat-six engine from the previous generation 911 GT3 RS and Speedster, with peak power now 510 PS at 8,400 rpm (fuel consumption combined: 13.3 – 12.4 l/100 km; CO2 emissions combined 304 – 283 g/km (as of 02/2021)) with 470 Nm of torque available from 6,100 rpm. This is enough to see the car hit 100 km/h in just 3.4 seconds when fitted with PDK transmission, and 200 km/h in 10.8 seconds.

The high-revving GT boxer engine features a host of enhancements, many of which have come directly from motorsport. The catalytic converter and particulate filter are now contained in a single housing, while new engine mounts increase rigidity and reduce vibration. Meanwhile, six individual throttle valves are used in addition to the central throttle, meaning each cylinder has its own valve for optimal air supply, located much closer to the combustion chamber for improved responsiveness. The GT3’s dry-sump oil system features seven suction stages and a variable vane pump to ensure optimum pressure even under the heavy lateral loads of circuit driving.

The gains made in the new GT3 – launched in head-turning Shark Blue – were in evidence recently at the Nürburgring’s infamous Nordschleife, when the car set a new record during final set-up work. Development driver Lars Kern took just 6:59.927 minutes to lap the full 20.8 kilometre circuit, making the GT3 the first production car with a naturally-aspirated engine to dip under the seven-minute mark.

However, this remarkable performance comes as much from weight-saving and aerodynamics as it does from raw power. The extensive use of aluminium, carbon-fibre reinforced plastic (CFRP) bodywork and lightweight glass mean that the new car’s kerb weight (1,418 kilograms with manual gearbox) is almost unchanged from its predecessor despite increased width, larger wheels and a significant increase in technical features.

The body design of this latest edition of the GT3 also offers much greater downforce thanks to a heavily revised aerodynamic package that includes a larger rear wing with swan neck mountings. This wing can be manually adjusted into the track-only ‘performance position’ which, alongside parallel adjustments to the front diffuser, improves downforce by around 150 per cent over its predecessor.

Porsche’s engineers have also extensively redesigned the GT3’s chassis, introducing a motorsport-derived double-wishbone front axle, which in combination with Porsche Active Suspension Management and rear axle steering with a GT-specific set-up, offers greater steering sensitivity and improved high-speed stability. Further chassis enhancements include rose-jointing, integrated helper springs on the rear axle and full chassis adjustment for track use, including toe, camber, and stabilisers. The GT3 also features mixed-sized wheel and tyre combinations, with 20/21 inch forged alloy centre lock wheels and high-performance road tyres fitted as standard.

The new GT3 comes as standard with the previous generation seven-speed PDK unit, chosen over the eight-speed option currently fitted to the 992 Carrera because it saves around 20 kg. This gearbox offers enhanced performance in the absence of an overdrive eighth gear with faster shifting and shorter ratios, both of which are better suited to the GT3’s naturally aspirated engine.

A six-speed manual gearbox is also offered from launch, equipped with a mechanical, rather than electronic, rear differential and fitted with the ‘AUTO BLIP’ rev-matching function for downshifts – a benefit in terms of both performance and reduced wear on the transmission.

The cockpit of the GT3 features hard-wearing, motorsport-inspired Race-Tex trim, appearing prominently on the centres of the electric Sports Seats Plus, the gearshift gaiters on both the PDK and manual cars and on the standard multifunction sports steering wheel. Customers will also benefit from new a button to reduce the digital displays on either side of the central rev counter to performance-specific information such as tyre and oil pressure, oil and water temperature and fuel level. The display also includes a visual shift assistant, with coloured bars to the left and right of the rev counter and a shift light. The latest Porsche Communication Management (PCM) is also fitted as standard, and all GT3 cars come with the Porsche Track Precision App, offering real time telemetry from hundreds of tracks around the world.

Extensive individualisation will be offered for the new GT3 via Porsche Exclusive Manufaktur, with GT3-specific options such as a lightweight roof made of exposed carbon fibre, exterior mirror tops made of carbon, darkened LED matrix main headlights and matching Exclusive Design rear lights. Inside, the instruments, Sport Chrono stopwatch, seat belts and trim steps can be ordered in body matching or contrasting colours.

Fuel consumption combined: 13.3 – 12.4 l/100 km; CO2 emissions combined 304 – 283 g/km (as of 02/2021)

  • 6:59 with Lars Kern, and doing what no other NA car has done before. Whoa.

  • I bet it's going to be another awesome driving machine, and sadly many will end up as garage queens.

  • I hate everything about it... I think Porsche should drop one around to my place for the week, and I’ll try and change my mind....
