Brace yourself for the new Porsche 911 GT3 Cup

Porsche’s 992 racer is more powerful and can run on synthetic fuels

Welcome to the first racing version of the 992-era Porsche 911, the GT3 Cup. Built for Porsche’s Mobil 1 Supercup and Carrera Cup series, it’s more powerful than its predecessor to the tune of 25bhp, taking it up to around 510bhp at a screaming 8,400rpm, and is “a good one per cent” faster around a track thanks to optimised aero and various chassis changes.

The 992 GT3 Cup uses the “turbo-spec” body for added width and broader shoulders. So it can accommodate wider wheels and tyres – 12-inches wide at the front, and 13-inches wide at the rear. More aluminium has been used in its construction – up to 70 per cent, versus just 30 per cent for the old car – but the 1,260kg 992 Cup is still a bit heavier than the car it replaces. The extra 35kg comes from the stronger safety cell. All the windows are lightweight polycarbonate and the doors, engine cover and rear wing are made of carbon-fibre reinforced plastic.

Underneath, the rear axle is “essentially unchanged” from a road-going 911, but the front axle uses tech from the 911 RSR for “more precise turn-in behaviour”. The shock absorbers borrow tech from the RSR and the Le Mans-winning 919 Hybrid, too, while the hydraulic steering has been junked in favour of an electro-mechanical setup.

The 4.0-litre N/A flat-six redlines at 8,750rpm. Which ought to sound… exciting thanks to new exhaust. Three different exhausts are available to cater for the regulations of different series and tracks. Porsche claims the six-speed sequential gearbox delivers quicker changes and can withstand 120 hours of racing without a major overhaul.

The engine has been designed to run on synthetic fuels, which Porsche claims “significantly lowers CO2 emissions under racing conditions”.

Elsewhere, special brake calipers mean pads can be changed faster, the fire extinguisher system has been made more efficient and the dashboard rearranged to make it easier to use.

All cars are delivered with a special accessory kit, so they’re ready-to-race straight out of the box. Deliveries will begin in February 2021, and soon after the 991 GT3 Cup will make its debut in the Porsche Mobil 1 Supercup and national Porsche Carrera Cups in Germany, France, Belgium/Netherlands/Luxembourg, Asia and North America. Yep, the UK has to wait a bit longer.

The price? €225,000 before local taxes.
