During Gran Turismo Events at the Nürburgring I have filmed several Porsche 991 GT2 RS's. As you can see the 'limited' car is pretty common during track days already. How many can you count?
The most extreme 991 generation 911 was revealed in full at the Goodwood Festival of Speed where Walliser gave us a tour around the new car. Faithfully following the same template as previous GT2s, the latest version has the same wild combination of the most powerful iteration of Porsche’s flat-six engine and a track-focused, rear-drive chassis.
The numbers are pretty astonishing, with the GT2 RS producing a maximum power output of 691bhp and 553lb ft of torque, from a 911 Turbo S derived 3.8-litre twin-turbo flat-six engine; some 120bhp more than a Turbo S.
The extra power is produced from bigger, higher output turbochargers, a reshaped carbonfibre air inlet, an improved filter and free-flowing exhaust. Further power gains have been garnered thanks to a water spray system that dowses the intercooler with water to help reduce the temperature of the charge air.
Its massive power and torque are transferred to the rear wheels via a seven-speed PDK dual-clutch gearbox. The resulting performance figures are just as insane, with the GT2 RS hitting 62mph in just 2.8 seconds.
Despite Porsche GT having recently developed a new manual gearbox, for Walliser, RS means PDK. ‘The more evocative, purists’ cars will be available with a stick, but we never thought of a manual [for the GT2 RS], it was only ever going to be PDK. There’s no need for a manual gearbox in this car.’
he possibility of the GT2 RS becoming four-wheel drive, like the 911 Turbo, wasn’t as quickly dismissed as the manual gearbox: ‘In the beginning we discussed it, but not for very long. The 911 concept [its rear-engined layout] means there’s not really a grip problem. In dry conditions...’
Porsche has thrown its whole box of tricks at the two-wheel drive chassis. It has rear-wheel steering, and a GT2 RS specific Porsche stability management system helping contain the prodigious power. All of this is sent through massive 325 section, 21-inch rear tyres. Like the GT3 RS, the GT2 utilises the wider Turbo body, but adds a far more aggressive aero package to the mix, with a huge rear wing and a more aggressive splitter.
The GT2 RS isn’t just a turbocharged GT3 RS, either. Walliser explains that the new car’s chassis set-up takes inspiration from the 911 race cars: ‘Compared to the GT3 RS, the anti-roll bars are softer, but we’ve increased the spring rates.’
The styling modifications have also been extensive. Behind the large front intakes are radiators and oil coolers to keep the engine and drivetrain cool. The vents on the rear haunches, finished in carbonfibre, are more pronounced than the ones on a 911 Turbo and help direct more air to the intercoolers. The bonnet mounted NACA ducts send cool air to the front brakes.
Inside, the spokes and gearshift paddles of the steering wheel are made from carbonfibre and the steel roll cage has been replaced by a lightweight titanium one. Walliser points out that the new material for the roll cage means it’s no longer FIA approved despite it being just as strong; you can sense the frustration in his voice.
Prices for the GT2 RS have been set at £207,506, with the Weissach package adding a further £21,042 to the total.
