The 718 GT4 might be arriving sooner than you think!

Either way, not great! But again, crap video, so who knows.

I can’t see someone going to the trouble of dubbing it anyway.

420bhp confirmed which is nice.

[Twinfan]

Yep, 420bhp and manual only for the GT4 and Spyder twins from the Rennlist source.

PDK will only be available on the 460bhp GT4 RS if they make it, and it'll be the only option.

That's a bit st when we can tune the 3.8 just with bolt on's to 435bhp !!!

If it has the same gearing it's a no go. So the new GT4 all rests on the gearing for me.

we know the 4.0L engine will do 600BHP, the GT3 R has 550BHP, the GT3 has 500BHP to detune it right down to 420BHP is sad.

GT4 RS PDK with a manual Spyder will be a nice combo to own.

[Twinfan]

The 4.0 is best thought of as a stroked version of the old 3.8 rather than a 100bhp de-tune of the GT3 lump, although I guess it amounts to the same thing.

It'll be like the last car - a nice enough engine but nothing special to get you excited about.

[RBT0]

st no PDK on base GT4? I need a GT4RS then.

[otisdog]

If they do the RS, they're not doing many, so they won't need much of a production window.

Fair point.... But.... It doesn’t amount to the same thing in many people’s eyes.... Think back to the reams of threads on PH regarding the “non-Motorsport” engine in the 981 GT4....!! It really did cause a 2 year long hullabaloo.... The GT division engines ARE quite different internally to the “regular” models, and many were hoping that Porsche would this time engineer a “full-fat” GT4..... This appears to now be unlikely....

So, if it IS just a stroked version of the old 3.8, we are likely to be having the same discussion all over again for a good while yet.... True “Groundhog Day” style...!!

Given there is balance of performance, why does Porsche necessarily need to build a faster car just to join the arms race? It's more a question of lobbying to get the more favourable adjustment than joining the arms race surely. Look at cars like the Mclaren 570 GT4, they are restricted by well over 100hp and carrying 100+kg of ballast.

If it was that worked flawlessly, we'd not see any innovation or new cars in the starting grids. It's a multi-round game. Producing a superior car can get you an advantage for some time. Look at how long it has taken the VLN to add weight and restrictors to the M4 GT4 that completely outgunned the venrable GT4 Vantage

Yep, history certainly repeats itself.... this is exactly the same as 2015 when the 981 GT4 was being anticipated.
Everyone wanted a tricked up 3.6 with 385hp. We got a 3.8.
Now we hear of a 4.0 but it won’t be the tricked up GT3 spec, so actually a tricked up 3.8 to get the same output would be sweeter.

For me the more interesting part will be what has been done with the chassis as this is really what the GT cars (GT2 RS excluded) are about imo... not out and out hp or engine.(else they’d all be turbo already).
How much faster will it be.. and crucially..what have they done with the chassis to achieve the performance. These are the elements that would make me think about changing from the 981 GT4 to a 718 GT4

[Twinfan]

The 'Ring time will be a big step on but it'll be some super trick tyres doing all the work. I don't see that the chassis will move on all that much.

Agree.... Just look at the 991.2 3RS.... How much of that phenomenal Ring time is due to the car, and how much due to the tyres/driver/altered track....?? Porsche will undoubtedly be able to “engineer” a significantly faster time in the new GT4, but the devil will be in the detail, I suspect....

Agree entirely.... Shame Porsche never seem to realise this, time after time.... A case of marketing taking precedence over true driving pleasure it seems....

I thought you said it was coming with 480hp. If they are not building many will it be a limited number like the 911R or just a limited production run?

[Twinfan]

460bhp is what the test mule has apparently. It would be like the GT3 RS - limited production by factory capacity, not a numbered edition.

I personally can't see the RS making production. This is probably why it's currently rumoured as "undecided" - it's too much of an issue in marketing/positioning within the sportscar hierarchy. I'm guessing the marketing department will have the yes/no say on it ultimately.

The new RS's Ring time would be 7 seconds slower on Michelin Cup 2 N2 or 7' 03s compared to 6' 56s on R spec tyres...the previous gen 991RS's Ring time would be 11 seconds quicker on the special sauce R spec MPSC 2s or 7' 09s which is 11secs quicker than the OEM MPSC 2s N1
Or to put it another way with the same tyres the Gen 2 RS is only 13s quicker around the Ring compared to the Gen 1 RS...

13 seconds is 1/2 that long back straight though which is a long way to be ahead.

And still puts the normal new GT3 faster than the old RS ;-)

I don't know, and given that it hasn't been decided if the car will be built, it seems that Porsche doesn't know either. U.S. dealers know very little about this car - but there has been a bit of elbowing by the VIP's to get a place in line. i don't think it will be 'numbered' but i do think it will be rarer than the GT3 RS by quite a bit.

Sounds like you are already lining up to flip the gt3.2

I don't believe there was any kind of recorgnised test with both tyres and neither has Porsche officially said anything. How/where have you got all these numbers of the Cup2 R being 7 seconds faster than the N2 or how the .1 would be on them?
