I agree that I does not make sense. Already the CS is there for track only duties. RS has always been the ultimate street/track car.

I think cleening ladies should do a meeting together and relay the same intel!

I'm really surprised on how we can still discuss about cleaning ladies statements on this topic, whereas I mentioned several times that this information was clearly given to me by my dealer, pediction for 2021, deposit can be open for an allocation LOL. Anyway, if it can make the topic alive! this information was known at the same time of the current 4.0 718 GTS, both with the 718 RS were on an internal document.

I am somewhat new to the games of Porsche; however, my dealer/SA has keeps saying the GT4 RS is happening. If it's an RS model, it will be track/street. Otherwise, it's a CS. Basically, the RS model for the GT4 platform (IMHO) is Porsches answer to everyone saying that the GT4 could've been pushed further (that more is to be had in performance). The cleaning lady might have gotten into the wrong chemicals because "not approved for street use" defeats the RS moniker and; therefore, this whole thread.

This is not from any dealer, my guy called the cleaning lady direct.
It will all come out in the wash eventually....

If this is the case then it will be very close if not the same dynamics to GT3 991.2

GrantG

Maybe you mean 991.1 GT3? Not sure why it would be same dynamics as 991.2 GT3 (which most in US chose Manual), different chassis layout (RR vs MR), different (motorsport) motor with 9k redline and more power, multi-link rear suspension, etc...

kart driver

why?
450 hp in GT4RS vs. 500 hp vs GT3RS.
And most likely mid engine car is easier to drive

GrantG

GT3RS has 520hp. Mid-engine car is not easier to drive - once you've used all the grip, rear engine is much easier to catch. Mid-engine car is easier to drive, right up until the point you've just spun If you leave ESC and TC on, then it takes more to spin (but I still find it much easier to explore slip angles with GT3 than GT4).

GT3/RS rear suspension allows much better camber behavior under load as well - 718's strut rear suspension doesn't behave nearly as well when really pushing.

kart driver

meant gt3, NOT gt3RS.

In hands of a typical driver midengine car is faster

GrantG

Which is faster is a debate that could on forever (and has), if all other variables are equal. In this case, all other variables are not equal (engine, suspension, gearbox, etc).

You are comparing models from 2 different model lines where the mid-engine one has traditionally been created with parts that are not to the standard of those in the rear engine line. Many of those parts will influence your statement about speed and ease of use. We'll have to be patient and see how Porsche specs the GT4RS to see what comparison is apt.

I agree that from the marketing standpoint it is very unlikely they will do gt4rs being on par with the former GT3 .2

My GT4 with mods can't match a 991.2 GT3 time (usually 1-2 sec slower), similar driver skills with me driving the heck out of the GT4 on Pirelli DHs.
The 718 GT4 my close the gap but will never match the .2 GT3/RS level of performance.... as Grant says the level of the parts used on the GT3/RS is way higher than the Gt4 (718 and 981).
I also agree with him on the handling characteristics once you are above 90%.....the rear engine with the RWS and multi-link provides a huge advantage.
You are getting to the point of reasoning why I'm very skeptical of a GT4RS.....it's a very tight fit on PAG lineup and the price delta between it and a GT3 will be so small you might as well go for it....be that 991.2 or 992.

Not sure I agree, tires can play a large role. My spyder is very neutral and communicates very well.

jmartpr

I think what Grant is saying is that once you get to 90-95% on a track, the Rear engine with the superior rear suspension will have an advantage.....what happens is that until you get to that point the mid-engine is a joy to drive (well balance, with good predictable handling) but once you cross that threshold things get interesting and you really have to finesse the car....but still the rear engine 911 will pull better out of turns and have less weight transfer under heavy threshold braking.
