Default 992 GT3 Speculation

So... time to open a can of worms with the 991.2 model cycle winding down!

It's pretty well telegraphed that the 991.2 model cycle will conclude with the following cars:

991.2 GT3 - On sale, deliveries in progress

991.2 GT2 RS - On sale, deliveries in progress

991.2 GT3 RS - On sale, deliveries forthcoming

991.2 Speedster - 4.0L 520 hp engine with manual available, 1948 units; the 911 R of the 991.2 generation

991.2 GT2 RS 4.0 - Rumored, perhaps forthcoming; may have something to do with the camouflaged car seen testing at Monza during the factory race car test recently

But on to the 992 GT3!

The following are my hunches (wishes?) based on a variety of sources (other speculation on Rennlist and Rennteam, spy photos, journalist speculation, conversations with FSW and factory drivers, etc.) - very much a mosaic theory.

Engine:

Naturally aspirated 4.0 liter flat six with a redline of at least 9,000 RPM, potentially higher

The race engines used in the GT3 R and 911 RSR rev higher than 9,000 RPM and make more than 520 hp before the fitment of sonic restrictors that reduce oxygen intake and inhibit power output for the purposes of Balance of Performance; revving above 9,000 RPM is an avenue they can use to make more peak power, assuming that the changes to the top end of the engine from 991.1 to 991.2 facilitate additional headroom in terms of maximum RPM and (corrected) mean piston speed. I believe there IS additional headroom to achieve higher RPM in a street car. That change might come in the 992 GT3 RS, however.

Additionally, the 911 RSR and new GT3 R engines have individual throttle bodies, which help throttle response and make the engines sound great too. Hopefully we will see those in the 992 generation.

I would guess the 992 GT3 will have a quoted peak power figure of 515 hp, just a tick below the 991.2 GT3 RS, officially attributable to the lack of ram air intake effect.

Recent FSW quote on SC365:

Head of Porsche Motorsport Dr. Frank-Steffen Walliser revealed that it had considered a turbocharged engine for the new Porsche 911 GT3 R, although ultimately ruled against it after simulations. “We went through it, but still with the rear engine, the disadvantage is too big,” Walliser told Sportscar365. “The weight distribution, you lose the freedom to bring in the intercoolers in the rear engine. It’s not optimum.”
Transmission:

PDK and Manual available

The existing 6 speed manual would carry over, since the engine - as detailed above - would be evolutionary and the transmission already mates up to the engine.

PDK will receive evolutionary enhancements and potentially have 8 forward gears to help achieve quicker benchmark acceleration times AND utilize a very low top ratio for fuel economy purposes.

Electronic Systems:

Expect continued improvements in steering feel as EPAS continues to evolve; also expect a revised, evolved RSW system with enhanced calibration

For the PDK cars, the E-Diff would likely be updated as well

One interesting thing that some competitors have done lately is a highly sophisticated, multi-stage traction control system - think Ferrari Side Slip Control and Mercedes AMG GT R's 12-stage traction control system modeled on the GT3 race car's system. I'm not sure that such a system fits with Porsche's philosophy, however.

Suspension:

The new 911 RSR has long had double wishbone front suspension vs. the relatively prosaic MacPherson struts that other 911s have had; the new GT3 R now has double wishbones up front too.

I think Porsche might fit a double wishbone suspension on the GTx cars in the 992 generation, but it would cut into - or eliminate entirely - the space in the frunk cavity. That might be an RS only thing.

Wheels, Tires, Brakes:

A new wheel design for the base wheel, which was the same for all 991 generation GTx cars; recall that the 997 generation got a new design, incorporating center lock wheels, at the facelift.

Based on spy shots, the 992 appears to have wider bodywork than the 991, so there might be room to use a wider rear wheel (and tire) on both axles - like the 991 RS models.

I think there could also be an option for a Weissach Package on the "regular" GT3 instead of just the RS models; Porsche loves segmenting markets. Perhaps they could price it such that a fully optioned GT3 with Weissach Package would verge on the base MSRP of the 992 GT3 RS...

Porsche has been experimenting with Magnesium wheels lately: 918 WP, GT2/3 RS WP - So why not offer those wheels on the base GT3?

AP has said that they don't view carbon wheels - as featured on the 991.2 Turbo S Exclusive Edition - as a track wheel, so those are probably out.

As for tires, expect the latest super duper Michelin tires, potentially in a larger fitment, affording a larger contact patch: 20" or 21" up front with 265 section width; 21" in back with 325 section width.

Finally, regarding brakes: I doubt the PSCB (Porsche Surface Coated Brake) technology will find a home on a GT car, but with the potential for larger wheels up front, they might fit larger rotors too.

Weissach Package:

See above section

Exterior:

The typical formula is well-known: air intakes up front, a vent ahead of the frunk, vents behind the rear tires, and a rear wing.

The wing will probably be larger and have more defined endplates as the quest to manage airflow effectively continues.

I would like to see the unique mirror design featured on the 911 RSR and new GT3 R - a "bullet" style mirror housing that mounts lower on the door.

I would expect Porsche to reserve exotic composite bodywork materials for the RS iterations absent a meaningful price decline in those parts from suppliers and/or competitor vehicles offering significant carbon fiber content in the same segment; this hasn't been the case thus far, however.

Touring:

Will continue, hopefully with additional interior customization options (different leather colors, etc.)

Pretty hard to say when we don't know what tricks are up Porsche's sleeve with the 992 platform. Would love to hear what cleaning ladies say regarding rumors of what may be going on underneath that bulbous exterior....

Methinks you have too much time on your hands.

Great intro post to this thread.. but about 2 years too soon.. put this on ice for 24 months or so as there is little info to go on.

Oh.. you forgot some kind of hybrid-NA motor speculation..

Nah, not too soon. None of the 991.2 cars entice me, especially in light of what I believe the 992 will offer.

Hybrid 992 GT3 won't happen, as you know.

700 hp 992.2 Hybrid coming - maybe you should wait for it?

Doesn't 2020 seem too soon? Was a large gap between 997.2 and 991 gt3

997.2 2010, 2011

991.1 2014-2016

991.1 2014-2016

I'd say yes. Will be a gap between initial 992 Carrera launch and GT version. Probably shorter than previous 3 year generation change.

I'm already onto 992.2

What's that gonna look like??

Anyone have a deposit down?? On "the list"??

992 fall 2018 at Paris show

992 turbo the next fall - Frankfurt IAA 2019

GT3 Geneva 2020

Just like 991 was:

Carrera intro IAA fall 2011

GT3 Geneva 2013 - 18 months later

Nope, not in regular GT3. Also don’t be so sure on no CF wheels offered on 992 GT platforms

How do we know the GT3 will stay NA?

The Geneva debut will preceded the actual on the ground cars by 5-8 months depending on market so that timeline could work.
