Re: 991 GT2 RS (2017) - Rumors, speculations and gossip
Good and fair question.
The 4.0 NA engine in the RS is great and sounds great, but the chassis feels like it could easily handle a lot more power and it does not feel THAT fast in a straight line. Not that this matters too much on track, but still the power and torque of the 997 GT2 RS were certainly impressive...
I wonder what engine they will use, a derivative of the current MH 176/MH177 engine generation? In other words, a turbo charged version of the (road) GT3/RS and (race) GT3 R engine, which could also be the base engine of the 2017 RSR?

KresoF1:It will be very unique and impressive limited edition supercar with true Motorsport genes.
Future favourite car of AP.
Really need to know more?
Which of these cars are its direct rival in terms of acceleration and time attack ?

Re: 991 GT2 RS (2017) - Rumors, speculations and gossip
How can it be as fast as the 918 on track or anywhere else? The 918 has more power, weighs less, is AWD and is equipped with more performance goodies than the GT2. What am I missing?

Re: 991 GT2 RS (2017) - Rumors, speculations and gossip
One reason can be weight,perhaps 275 kg less than the 918. The 918 full fuelweight is 1642 kg accordingly to SportAuto Supertest ans the 997 GT2 RS was 1400 kg. Correctly bult the 991 GT2 RS could be 1360 to 1375 kg full fuelweight weight. Then it could be close to the 918.

I think Kreso meant that this might be a goal in the development - it is super unlikely to happen though...

Nick, a GT4 ClubSport will lap almost any track as fast as the 918, and that car only has 385HP.

Well, but don't forget that the GT4 is the fastest and meanest machine on the whole planet.

We're at the point where you can be the fastest or just sound like you're the fastest.
The secret of life is to admire without desiring.
Re: 991 GT2 RS (2017) - Rumors, speculations and gossip
A GT4 Clubsport can lap faster than a 918... if it's on pure racing slicks, has a set-up that would probably knock your fillings out on the road, and stripped to the metal.
That said, I think a GT2 RS could maybe get close to a 918 with enough power, sticky tires, and a track that can use aero. A new ACR Viper can get within spitting distance of the 918 even though it's literally like 5s slower to 200 kph in a straight line and can't even reach 300 kph.
Re: 991 GT2 RS (2017) - Rumors, speculations and gossip
To beat a 918 on the track means a car has to have a massive cornering speed advantage. ACR Viper has that.
The main advantage of the 918 compared with rest of the field is that it has unbelievable brakes and the amazing acceleration out of turns.
Spent the last 3 days with Matthias Hoffsummer, he has logged more miles on a 918 than any other human being on earth. He also has extensive sessions with P1 and LaFerrari. On a track, the 918 is basically using the same brake points as a GT3Cup car, difference is that the 918 can trail brake really deep into a corner, the weight transfer and the RWS means the car will rotate proper without spinning out and then get on the gas really early to rocket out of a turn. But one has to trust the car in order to do that, not many trust it that much. It's easy to extract 95% out of a 918 than a P1 or a LaFerrari, but it's much harder to extract 100% from a 918 than the other 2.

Same brakes as GT4 (optional)

Indeed, and presumably the 918 is reaching those braking points at a higher speed than the Cup car..?

Re: 991 GT2 RS (2017) - Rumors, speculations and gossip
Gnil:What hides that black sticker on the upper part of the bonnet ? It looks like there is a big opening there in the middle ......
I don't think that is a sticker so much as just the effect of warmth rising from "technical" items under that part of the bonnet (battery, fuel tank, etc.). The area of the bonnet ahead of that is just luggage space, with no heat sources.
PS: If the air extraction vents at the upper rear areas of the front wings were really so effective in increasing aerodynamic downforce at the front of the last GT3 RS, I'm surprised that they have not been carried over to the GT2?

964 Carrera 4 -- 997.2 C2S , -20mm -- 991 GT3 RS
This seems to be the normal "heat pattern" on the carbon hood (same as with GT2RS), i.e. there is more warm air in the upper part of the bonnet plus the material is thinner up there (no reinforcement beneath in that area) 
Re: 991 GT2 RS (2017) - Rumors, speculations and gossip
I agree with Spyderidol, a 991.2 GT2 RS could very well be the homologation vehilce for the 2017 911 RSR, the new works race car for the top GTE pro class. The size of the limited edition would be driven by the requirements of the WEC and Le mans regulations.
Re: 991 GT2 RS (2017) - Rumors, speculations and gossip
PS: if I read the regs correctly, only 100 road cars for homologation are required for GTE pro cars (for "large" manufacturers such as Porsche): Spyderidol, you may want to double-check this.
If true, this would set a very low bar in terms of the minimum size of any limited edition road car.
