I base my opinion on the fact that at least 9mos will be required to complete the GT3 fiasco and the RS will follow that. No turbo, minor HP increase (5%), some additional carbon, and new aero. The test cars running around are NOT turbos, fender inlets are for cooling. This will probably be the last Road GT produced that is normally aspirated.

Just my opinion.

That would be a 2 year gap from 991 GT3 at Geneva. Unprecedented, but so were the failures of course. IF that transpired then the RS would almost surely be a VERY short production run so as not to overlap with the 991.2 facelift of the mainstream models.

As you noted, the mules running around look to be NA, incremental evolutions of the new GT3, not a fundamental philosophical sea change.

There is also the issue of 981 GT4 existence/market positioning/timing.

Who knows? Let's hope not!

Occurs that one definite constraint point on engine choice for the RS will arise when the normally aspirated (NA) motor starts to be infeasible from an emissions standpoint....

Audi already pointing to differentiated engines for the R8 gen 2...with Turbo's for markets where emissions inhibit NA....

Could be we revisit the late 70's...with marked engine differences/states of tune between markets..

Of course Porsche might be able to ride limited production waivers and/ or fleet averages to still secure a NA engine for RS...at least in some places...

That seems to be Lambo's path for the Huracan...

Guest89

There will probably be fewer than 2,000 991.1 GT3 and RS produced period. It's not a volume car. Conversely the Huracan will be Lambo's volume model...

CAlexio

Aren't fleet averages counted under the entire vw corporate umbrella? It's the skodas and seats which allow for the lamborghinis and bugattis to exist no?

if anything the delay was caused by having to build an extra 485 engines, and probably ensuring that the RS engine was further bulletproof, I very much doubt PAG threw the RS engine out and started from scratch to add FI at the 11th hour, engine design and production does not happen like that.

Larry Cable

you could argue that the pictures of the 991 facelift have indications of this:

1) venting on the rear bumper ala dual intercooler designs from the TT's since the 996...

2) new rear center exhaust design...

Larry Cable

fender inlets are actually the engine air intakes ala the RSR intake system...

Larry Cable

they already have a TT engine ... the one that's in the TT/S ...

^Who is to say that it was going to be turbo charged all along?

At this point I do not think any one has any confirmed info. that the RS will be NA. I would be surprised if it was not but who knows what direction they are headed in. If it is turbo charged I do not know how many buyers they will have but they also said that about the GT3 going PDK-only. If they put a turbo charged engine at about 575 HP and get the weight to about 3000 lbs - that would be something. In other wards; a Turbo S for racing.

Larry Cable

isnt that called a 'GT2 RS'

Jimmy-D

Yep - That is why I do not know how there line-up will look when they do decide to start turbo charging all their variants. I get the GT2 because that if rear wheel drive but may be the GT2 RS ceases to exist.

Why not just make a 4.0 NA engine with 525 HP? They had no problem making it 500 hp. Why not make it 525 but limit redline to 8700rpm? Take a 150- 200 lbs out of the car and you have a good deal.

TRAKCAR

Who knows. The new M3 is just and M3 not an M3TT
Can you imagine how fast it is with all nannies on, full auto PDK-S?

The only trade off is the sound, but then no Porsche sounds like a 6.2L AMG...

GreenLantern

But, there's never been two track variants of the M3 at a given time (an N/A version and a TT version). There have been a GT3/RS and a GT2/RS simultaneously for the past three generations.

Bob Rouleau

The RS will be a 4.0 DFI engine - that's the official stance of PCNA.
