Newsflash. The handwritten notes of the head engineer on the Porsche GT2RS project have been leaked and are very "telling." For the Nordschleife record run, the car was run on 102 octane allowing the timing to be advanced some 6 degrees from stock. Also, the tires were shaved 50% prior to mounting for the run. Is this stuff cheating? Decide for yourself.

Except this was 20 years ago.... Today car manufacturers have other, more effective tools for cheating with laptimes.

Lap times in road cars are so irrelevant,that's stupid,who cares?

The great thing about Porsche is you can drive your gt2rs from home to the track everyday, destroy everything there, then drive it everyday to work without a problem. Porsche builds street legal track cars

Depends. A completely stock car going under 8:30 at the Nordschliefe or 1:50 at Laguna means the car can go very quickly down your favourite twisty road. However, the all out pursuit of the fastest lap can be rather bonkers at times

I think they are pretty much on the same level when it comes to racing-performance. Porsche is always very conservative with it's performance-declaration and the official numbers are obviously higher than the real ones. The GT2 RS has been tested in 2.7s on 0-100 kph / 0-62 mph and also the 0-200 and 0-300 kph times are better in reality. A professional comparison of both supercars would be amazing. Testing them on a circuit, on the road, their daily-driving abilities and everything in detail - like the steering, gearbox etc. - a huge test. The 991.2 GT2 RS and 720S are currently def. the most amazing supercars one level under the hypercar-segment with beasts like the 918 Spyder, P1 etc.

In my hands the 991 GT2 RS (WP) can win a race against a 720S !

Porsche may need your services as a test driver, because 720S looks to have the GT2 RS covered. On paper, at least.

As all criteria almost the same but the 720 s has mid engine and the Porsche has rear engine then i will say the 720 s will win

Porsche will definitely be faster around a track

Would not bet on it: 720s is lighter and has a bit more power with acceleration beyond 100kph is also slightly better, so all in all while be close but the pure numbers give the 720s a slight edge

FastestLaps  1y ago @Chris 1234

We only got Porsche's official numbers for GT2 RS and, historically, they have always been on conservative side. Remains to be seen what it can do in magazine tests. Both cars need more testing.

saxy  1y ago @FastestLaps

Yeah, just like how the normal turbo is claimed to do 0-200 in just under 10 seconds yet in tests they've been in the 8's.
There's no way this car isn't doing 7's. It also the advantage of more weight over the back wheels

chris 1234  1y ago @FastestLaps

Well from what we see in the first small comparisons between the 720s and the 675lt, the 720s looks also a bit like an overachiever ...

User avatar

Alejandro  3w ago @FastestLaps

The GT2RS has consistently been 1 second slower 0-200 kph than the 720S in magazine testing (AMuS and Autobild) and between 3.5 to 4 seconds slower from 0-300 kph. 720S destroys it in a straight line.
