Hopefully that reduces understeer but compared to the 991 GT3, the rears grew too (width AND length of contact patch) so hopefully there is more engineering differences to further reduce understeer.

The increase in front track width does point at the possible removal of the RWS, as this much more tire gives a lot more grip, whereas the GT3 with RWS seemingly doesn't need it. Maybe not though.

This car is the homologation car for the upcoming GT3-R, and the other fleet of factory race cars they will sell next year and beyond. Not surprising they are rolling out a new engine. To compete in GT3, you need to on top of your game.

Kinda sucks for everybody who bought a 991 GT3 though.

Mvez, would not expect to see a new engine in the GT3R. Expect Porsche to stay with the Mezger. All indications are that the new GT3R will have heavily revised aero only. New GT regulations are anticipated for 2016. Would not expect a new engine before the new regs are announced.

If the RS does not use a derivative of the 991 GT3 engine then it will have to use the old Metzger engine. If it uses the Metzger it will not have PDK at all unless Porsche has found a way to adapt it to the Metzger block which it previously was unable to do (or so it was said). If true (PDK/Metzger)then why bother w/ the new engine at all in the GT3?? There will be no third engine as that makes no sense from a time, engineering, or homologation standpoint. Let's not forget the "journalist" initiated rumor that the GTS was going to be a 992. Most likely RS is a 4.0L 991 GT3 derivative w/ PDK-S and no RWS.

LOL!

1. I don't believe Andrew's "brand new engine" just like I didn't believe Jonny Leiberman's 992 way back (roughly September I believe) when he said it was going to be introduced at LA (or NY) auto show or something to that effect.

2. If they roll out a different engine than the GT3, I along with many will grab our pitch forks.

3. Listen to the car thumping the Nurburgring, sounds just like 'the standard GT3' I couldn't tell the difference even if I tried to nit pick.

Nice we are on the same page. I wrote my above post before I read yours.

Lots of previous GT3 owners "grabbed pitchforks" when the 991 came PDK only. We saw how that worked out. And the manual supporters had supporting arguments beyond financial self-interest. Arguably quite the opposite, in fact...

Zulu Alpha

I will grab 2 then!

never noticed the 991RS Nurburgring video when exiting the corners the car shows a 50-80 HP added and the speed of the rev?

indeed that s no related to aerokit NOR 4.0 but by an additional system helping the car in low mid RPMs and it s not a Turbo from what i was told

Indeed there may well be something very special that has been added to the new RS to increase performance... We shall get the answers we have all been waiting for in 7 weeks! Unless Porsche delays the RS further...

all things being equal, the lighter car will be better. That being said, with the latest of technologies that have added weight to cars, their benefits negate the disadvantages of the extra weight. The GTR proved this. They're pigs on the scales but there's no denial how fast they can get around the track. So has the 991 GT3's RWS and PDK-S

BTW, here's my call on how they're going to extract more power. I'm going out on a limb and making my call right now

Porsche system is way too heavy - I believe it's about a 400 LB add to cars (e.g. Panny S E-Hybrid is 4619 vs 3,990 lbs for Panny S vs 4,244 lbs for GTS).

They don't have a light weight solution which is why the 918 is over 400 LBs heavier than the P1 and LaFerrari.

Regards, Porsche told US dealers on October 15 it's a 4.0L NA - I heard it from several of them.

Can it be an electric supercharger?
