New prototype!

Does the new GT2RS just seem to be a GT3RS with a turbo engine. Looks very similar to the GT3RS.

It's a prototype of the GT2 RS from what i heard can also be the 992.2 GT3 RS (rumored to be twin turbo).

Salesmen at my local Porsche dealership told me about six months ago that 992.2 GT3 RS will be turbocharged. If that will be true we will see...

I received similar information at the beginning of the year, but one source had kept my hopes up for a final NA generation. I must admit that I don't quite understand the appeal of a GT3 RS "turbo" won't it be too similar to the GT2 RS? Both will be turbocharged, and the only notable difference in terms of the engine will be that the GT2 RS will be a hybrid. Well, we'll see. More power is good for the GT3 RS but what about the emotion of a NA engine? And at what price!? GT3 RS is already Very expensive but that another issue.

About this pic i think it's not the GT2 RS but a new SSR Performance car.

Seen this car in the video below yesterday. Is it an old GT3 RS mule or kind of a GT2 RS mule?

Thanks! The car on the video look to be the 992.2 GT3 RS (No hybrid sticker) the 992 GT2 RS will be hybrid.

Confirmed this is not the GT2 RS but a SSR Performance car

That would be seriously f#cked up. And make zero sense.

I used OptimumLap to simulate experimental 992.2 GT? RS that uses Turbo S' 3.6L hybrid engine setup:

• torque curve is based on carwow's Turbo S dyno graph
• combined power to the wheels: 660 PS & 780 Nm
• ICE alone is 680 PS (at clutch), meaning 190 PS/L (Turbo S = 178 PS/L, 991 GT2 RS = 184 PS/L)
• weight is 1,650 kg including fuel and driver (90 kg heavier than GT2 RS)
• it has tires (Cup 2 R) and aero of 992.1 GT3 RS
• A: 2.3, Cd: 0.39 (DRS), Cl: 0.955 (660 kg at 250 kph)
• Vmax 335 kph (drag limited, gear ratios of 991 GT2 RS)

The result is marginally improved track performance vs 991 GT2 RS MR!
-4s Nordschleife
-2s Spa Francorchamps
-1s Hockenheimring
-1s Laguna Seca

The only problem is that Manthey would be unable to sell people an upgrade kit, since the tire load is totally maxed out.

These lap times simulations pretty much confirm what I thought : Porsche is going to need a hypercar to just touch the AMG One. Even if we assume Manthey Racing pulls off an upgrade, it still won't be enough. We're reaching the point where the 911s are starting to get really heavy, and it's costing them. Also, looking at the cooling needs for a future 992 GT2 RS, I doubt they could pull off 3RS downforce again ? Remember, the 991.2 GT3 RS was superior to the GT2 RS in downforce,as the latter only could tie the 991.1 3RS in that department. This is just speculation anyways, and there are also rumours about a 600PS+ Turbocharged GT3 RS coming. Let's wait and see.

Yep, AMG One is untouchable by anything lesser than a $1M+ carbon monocoque based super/hyper-car. And it's good to temper expectations regarding this upcoming GT? RS.

That said, there's other intriguing performance contests for Porsche in lower tier of sports cars: You've got AMG Track Sport, Toyota GR-GT, the rumored 296 XX, GM still hasn't had the last word with C8 platform...
And should my speculation come true, the T-Hybrid does make for a good enough performance gain to be in the mix with most of those cars.

Sure, you could make a faster car by going the non-hybrid way: twin turbo, less weight, more downforce...
But that's probably not realistic for Porsche, given the strict emission standards. Every mid-engined Ferrari is a hybrid. Every Lamborghini sportscar is a hybrid. 750S replacement likely will be hybrid. The trend is clear.

One way to get even better performance with Porsche badge is to go ask SSR, who seems to be working on a GT3 RS based project with twin turbo bolt-on kit and near Manthey-level aero. Although even that doesn't have a chance of beating AMG One.
