Weight here is DIN weight = car with 90% fuel, no driver, no cargo. Weight of German versions with standard equipment.


How a rear-wheel drive car achieves the promised acceleration figures is unbelievable. The engine comes from the Turbo S and is further tuned. There is an intercooler water spray system. The exhaust system is made of titanium and weighs ~7 kg/~15 lb less than the steel system in the Turbo. Like the 991 Turbo and the GT3, the GT2 RS has the weight-increasing, but hopefully time-winning, rear-axle steering system. The wheels and tyres measure exactly the same as on the 918 Spyder or the 991 GT3 RS: fronts are 9.5x20" with 265/35 tyres and rears 12.5x21" with 325/30 tyres. For the first time in a street legal Porsche, ball-joints are used in all chassis bearings. The 911 GT2 RS comes with PCCB Porsche Ceramic Composite Brakes as standard (steel discs more reasonable for motorsport use might be available from Porsche Motorsport). Carbon fibre reinforced plastic (CFRP) is used for the front lid, front wings, wheel housing vents, outer shells of the mirrors, side air intakes, rear lid, rear ram-air intakes and rear spoiler. The roof panel is made of magnesium or CFRP depending on the configuration. Typical to the RS Porsche, it is possible to order the 991 GT2 RS without air conditioning, audio system and the screen. Keep in mind though, that cool head makes better lap times than would help you the few extra horses or marginally lower weight.


RS without roll cage and bucket seats

Although in USA we have agreed to a law that bans roll cages and no real-RS (RennSport, German word for racing) Porsches have been sold in the USA, it is the first time that RS Porsche does not have the roll-cage as standard in Europe and that the RS can be ordered without the bucket seats. A racing car without bucket seats and a roll cage is not a racing car and when specified like that, the car should be called 911 GT2 instead of GT2 RS.


Clubsport package

The weight of the 991 GT cars is up compared to the 997 GT cars, so, the standard specification of the GT2 RS does not contain the Clubsport package in order to have lower weight on the spec sheet. The rather heavy Clubsport safety package includes the steel bolt-in roll cage including reinforcements with connection to bodyshell, 6-point racing harness for driver, fire extinguisher and preparation for battery disconnect switch. The 991 GT2 RS is 100 kg/220 lb heavier without the Clubsport package than the 997 GT2 RS was with the Clubsport package. Considering the Clubsport package is around ~30 kg/~66 lb, then the 991 GT2 RS is ~130 kg/~290 lb heavier than the 997 GT2 RS was. Similarly equipped, the heavier 991 GT2 RS still has a 3% better power-to-weight ratio compared to the 997 GT2 RS.


Weissach package

To get the roll cage that is needed for 6-point harness and for added safety without adding weight to the car, the solution is the Weissach package. It uses titanium for the safety cage and magnesium for the wheels saving ~30 kg/~66 lb compared to the Clubsport package cars. So, the Weissach version more or less retains the weight of the standard car, but has the needed safety equipment and unsprung masses reduced. The titanium safety cage designed for track day use saves 12 kg/26 lb compared to the steel unit, but is without motorsport approval. The lightweight wheels come straight from 918 Spyder Weissach version saving 11.5 kg/25 lb compared to the forged aluminium wheels. Anti-roll bars, coupling rods front and rear, steering wheel trim and shift paddles use CFRP. There is a plaque with Weissach package logo on the dashboard and headrests are embroidered with Weissach package logo. The front lid and the carbon-weave finish roof are emblazoned with a central strip in the car color. Rear wing comes with large ‘PORSCHE’ logo. It is possible to order the Weissach package without the roll cage.


700 hp

In high-speed acceleration the weight doesn't make much difference, but power does, and the 991 GT2 RS is clearly beating the already insane 997 GT2 RS there. The 991 GT2 RS has similar acceleration to 200 mph/320 km/h as the 918 Spyder!

Because of the many unpainted carbon fibre parts, the car looks most serious in black. Of course, a GT2 RS is über-cool in every color, even if it looks childish.

Mark Webber said at the 2017 Goodwood Festival of Speed that the 991 GT2 RS is a "King Kong" and that he did 336 km/h (209 mph) on the Nürburgring.


6:47.3 Nürburgring record

On September 20, 2017, the record time of 6:47.3 was achieved in the presence of a notary. It surpassed Porsche’s own expectations as at the start of the development process the target was set under 7:05. The new 911 record even beat Frank-Steffen Walliser's (Vice President Motorsport and GT Cars) previous baby, the 918 Spyder supercar, which had lapped the Nordschleife in 6:57. Do you even remember that the Carrera GT supercar could lap it in 7:28? OK, it wasn't the best-handling Porsche, but the difference between the supercar's 7:28 and the nine-eleven's 6:47 could be measured with a calendar as the racing drivers say. The already insane 997 GT2 RS could lap the Nordschleife in 7:18. The 991 GT2 RS is almost half a minute quicker than its predecessor. This is incomprehensible.

During the record attempts two cars were used by Lars Kern and Nick Tandy. They managed to do five laps under 6:50 and the record was done by Lars Kern, who has delivered Porsche Nordschleife records before. The new 911 GT2 RS Weissach lap record translates to a average speed of 184 km/h (114 mph).
