While we wait for the next GT3 I thought we could keep a list going as information comes out. Already we've seen a trickle down effect happening on the 992 Carrera and should be in for more surprises with this flagship trim. Here's what I found out so far:


  • 4.0L flat six with increased displacement and power to 516 (up from 513)
  • seven-speed PDK with an optional manual transmission
  • increased carbon fiber
  • advanced weight cutting technology
  • bigger focus on aerodynamics
  • "something special for race tracks … like you already can see on motorbikes" according to a Porsche executive

Hi.

Im new to the forum. Great to see a place to hand out and discuss the 992 GT3 which is a car Im very interested and learning all I can about.

Im a 991.2 GT3 (Manual) owner, clubsport spec car. It replaces a 981 GT4 and a 991.1 GT3 Clubsport. I use these cars almost exclusiveluy for circuit work and back road blasts. Im based in New Zealand and have owned Porsche for 20 years with a long list of models from 993RS and newer.

I have a 992 GT3 on order and Im very excited by the prospect even being a more "traditional" owner. I believe it will be a significant shift forward like the 991.1 was to the 997.2 GT3. Mostly Im refering to its competency on the track as I dont use the GT3 as a road car for daily duties. Im also excited by the tech.

So what tdo we know (facts and otherwise)?
  • 1). Launch Geneva March 2020 (not a fact but highly likely looking at previous GT3 cycles and launches and how developed the current prototype cars appear to be).
  • 2). 4.0L with 6 x ITB and PF (in markets where its required - i.e. EU). Not a fact however it is on record from a PAG employee at the 991.2 Speedster unveil that that engine will serve as the starting poing for the new 992 GT2 program. The engine is thus likely to have different injectors and higher fuel rail pressure with a small change in compression.
  • 3). Power likely 520PS (516bhp) with torque 346lbft (so same as outgoing RS but likely makes its power differnetly on the rev band)
  • 4). Wider front track as per 992 Carrera. (fact)
  • 5). Front tyres now 255/35/R20 and rears now 305/30R21 so wider typre patch front and rear for better lateral grip and braking. This is more or less a fact as the tyre widths are visible on the mules. Looks like Michelin already have a new staggared set of Cup2 ready for this car...
  • 6). PDK and manual. PDK is almostcertainly to be the 991.2 7 speed PDK unit as stated in two seperate interviews by PAG management. This is good as its proven and lighter than the 8 speed unit and the GT3 doesnt need overdrive.
  • 7). More aero. The new car will have depper diffusers that start earlier on the undertray of the car for mroe ground effects. The rear spoiler is likely to be larger and using a "swan neck" type design for better flow of pressurised air over the foil. The imporvements are likely to be significant enough to give the 992 GT3 downforce similar or excess of the 991.1 GT3RS. Thes eare more or less facts as you can see form various Nurburgring videos including the one with the car parked at the side of the track.
  • 8). Creases in hood, intake grill for cooler now part of hood not front bumper, new headlights, new door haandles, updated interior and electronics, re designed sports seats - these are all facts based on production 992 Carrera and GT3 prototypes

It would be great if we can update this list when we hear or see new developments. The 992 GT3 will be an impressive machine on teh track and early accounts from what I understand have indicated the car will be close to 7.00 at the Nurburgring with the factory supplied Cup2 tires. These improvements will largely come form the wider track with larger tyre patch no doubt improved resolution dampers with new programs for PASM and RWS and EPAS and of course aero/downforce. The engine should be fractionally more responisve and make a little more mid range torque and top end power. Turn in and steering feel should also be enhanced over 991.2. It would be really nice if they would update the Carbon bucket seats and a new folding one would be even better but I dont think we will see this in the 992.1. Also it appears the brakes will stay as current generation brembo (size and design) for both steel and PCCB (the upcoming 992 Turbo being released in the next month or so should confirm). I expect weight to increase only marginally (but they way they have to report it is now changed from last generation)....

Hi Touge. We wont see any shift in powertains for 992.1 GT3/RS. I understand still the 4.0L unit for both. At the end of the 992.1 product cycle we should see a one off 992.1 GT3 "RS 50th Anniversary" variant. This is to celebrate 50 years of the original announcemnet of the 2.7 RS in 1972. My bet is they will keep the 4.2L engine from the recently announced RSR for this last of breed edition. It will be limited in numbers and no doubt very special (like the recent 935). Think of it like a last gift (similar to 997.2 GT3 RS 4.0) before hyprid technology starts to creap into the 992 product range starting with 992.2. As for GT2 I expect the 992 GT2RS will be based on the 9A2 4.0L architecture as recently announched in the GT4. Getting 700+ bhp from this unit will be very easy (175 bhp per litre same as the factory tine on the Alfa Romeo Giulia QV by example). Turbo is much easier and cheaper to extract power - even the internals dont need to be as exotic).

Hi Touge. Id have no idea myself as the turbocharged cars are not something I particularly follow. Id imagine tuners will easily get 700+ bhp from the new 992 TT when it break cover, probably from a simple ECU tune. More than that may need change of intercoolers, turbos and exhaust. The GPF system will be thefirst hurdle for them to get their heads around I guess....

Yesterday these pictures were posted fresh from Nurburgring and 992.1 GT3 testing. We now see the mule wearing a different set of wheels. The rear spoiler foil now looks more sculpured with a gurney flap and of most interest we now see the finished diffuser exit piece below the centre exhays which has been missing until now. Sources indicate the car will be moving from European circuit testing to hot/cold climate testing next month and will be on target for March 2020 Geneva reveal...

Found a report on it with more information for anyone interested. Great catch!

Earlier this year we stumbled upon a video of a 911 GT3 prototype that lacked the typical, for the model, massive rear wing. At the time, we speculated that the car was the upcoming GT3 Touring Package, and now came across yet another test mule that fits the same description.

Unlike others, this one featured the standard rear spoiler of the regular 911 from the latest 992 generation. It also sports a new rear diffuser and lacks the GT3 air vents behind the rear window for engine cooling.

That said, it does feature other typical GT3 identification marks such as the center lock wheels, oversized brakes, and central double exhaust pipes. This leads us to believe Porsche has already started working on the new 992-based GT3 Touring Package much earlier in the model’s life cycle than it did with the 991.2-based version.

Given the absence of interior photos, we can’t tell if this prototype features a manual transmission like its predecessor, but we sure hope it does, even as an option. In any case, the engine will still be a naturally aspirated flat-six, in all likelihood displacing 4.0 liters. Power should increase compared to the previous 911 GT3, with some reports talking of 520 HP (527 PS), which should be more than enough to satisfy prospective customers.

Logically, the production car will launch after the “regular” 911 GT3 that is expected to make its debut at the Frankfurt Motor Show next month, which means some time in 2020.

Here is a video of the manual touring version testing a few days ago. Go to 120 to hear the engine proper...

This new video of the regular 992 GT3 shows it lapping the Nurburgring. Love how much more aggressive it is than previous GT3's!


Can't wait to see it in full at Frankfurt Motor Show next month.

Hi Ricky. thanks for those. The car is pretty much ready to unveil!

Of interest you can see the Turbo is sporting what appears to be a new front and rear caliper design over the 991 fixed bridge Brembo units. The openings at the rear of the caliper appear larger for better ventilation. I imagine the design is still very stiff but hopefully will be lighter and easier for pad changes than the current design. Also of interest (although it may just be an optical illusion) it appears the front PCCM rotor has a smaller bell housing allowing a larger swept rotor area. This would mean larger pads for more effective braking/cooling and better life. I have the 991.2 Gt3 with PCCB so have studied the pictures closely against my set up. The outside diamter of the rotors appears the same but the inside looks smaller. Such a brake set up will no doubt be offered on the new 992 GT3 and I would expect the steel set up to hopefully benefit from the same caliper upgrade. Of course we wont know for sure until the Turbo is formally launched n the next few months...

A quick summary on a few deatils of the upcoming 992 GT3 that we know, and some that we can be fairly confident will happen from what we have seen on the prototype cars or heard from PAG official sources:

Wider front and rear track
20" front and 21" rear wheels
New Wheel design (Center lock)
255/35/R20 and 305/30R21 tyres in new Cup2 formulation
Likely new larger/improved brake rotor and caliper hardware
New interior
"Goose Neck" rear aero blade (adjustable)
Improved diffuser with depper larger rear fin exits
Improved RWS and EPAS
Revised shocks and PASM calibration

Engine capacity likely 4.0L with 6 x ITB set up from Speedster and GPF (estimated 520PS and 346lbft)
PDK likely 7 speed from 991 gen
6 Speed manual
Possible composite hood
Alluminium rear fenders

NurburgRing estimates we have heard are low 7s with factory supplied Cup2 tyres...

All that is left now if for them to design an entirely new folding/fixed bucket seat and it will be basically an all new package!

Adding to @Macca's info, this is some other GT3 info we can depend on:

2021 Porsche 911 GT3 Will Still Have a Naturally Aspirated Shriek
The 992-generation GT3, which we spied at the NĂĽrburgring, will have a 4.0-liter flat-six and possibly an optional manual transmission.
  • We spied the 2021 Porsche 911 GT3 testing at the NĂĽrburgring and now have a closer look at its exterior details.
  • We're getting a closer look at its dual hood vents, center-lock wheels, rear diffuser, and dual center-exit exhaust tips.
  • The new GT3 will be powered by a naturally aspirated 4.0-liter flat-six.
High-revving, naturally aspirated Porsches excite us. When we tested a manual-equipped 991-generation 911 GT3 in 2018, we said that "it delivers a driving experience so glorious that we can't help but wonder if it is a great Porsche or perhaps the greatest Porsche." We might have to re-evaluate our choice of words soon, because the 992-generation GT3 might be even better.

We've spied the 992-generation GT3 testing on the NĂĽrburgring before, and we've seen a brief sneak peek in Porsche's 2020 Super Bowl ad. Here, we're getting an even closer look at the new GT3's looks. Its hood has dual hood vents, the center-lock wheels are similar to the ones we saw in the Super Bowl ad, the rear diffuser looks more production-ready, and the dual center-exit exhaust tips are still there. This prototype has a fixed rear wing, like previous GT3s, but it's unlikely that the production GT3's wing will look like this. As for the ducktail spoiler, we hope that stays.

We expect that the 992-generation will be powered by Porsche's high-revving, naturally aspirated 4.0-liter flat-six. In the 991 GT3, it produced 500 horsepower, while the hard-core GT3 RS spun out 520 horsepower. The 992 GT3, however, should get a slight bump in power. The six-speed manual, recently introduced for the 992 should be an available with a PDK dual-clutch automatic as an option.

We've already seen and driven the 640-hp 991 Turbo S and Turbo S Cabriolet. Expect the 992-generation GT3 to make its debut sometime late this year, and a race-ready GT3 RS version will surely follow. Pricing is expected to remain close to the 991.2 GT3's $144,650 base price.

Porsche recently revealed the 992 GT3 and here's what you need to know about it.

Motorsports technology meets the road: The 2022 Porsche 911 GT3

High-revving, naturally aspirated engine shared with 911 GT3 Cup, double wishbone front suspension adapted from 911 RSR and a choice of PDK or six-speed manual transmission

Atlanta, Georgia. Porsche continues the tradition of transferring what it learns on the race track directly to cars designed for the road in its latest model, the new 2022 911 GT3. Making use of extensive lightweight materials, refined aerodynamics and a motorsports-derived double wishbone front axle layout, the new 911 GT3 aims to raise the bar once again.

“With a soul that’s born in the Motorsport, the new 911 GT3 sends a driver’s heart racing,” said Kjell Gruner, President and CEO of Porsche Cars North America, Inc. “Whether it’s a customer enjoying their favorite twisty backroad or taking to the track, the new 911 GT3 promises to be among the most exciting and rewarding cars we make.”

Engine: The heart and soul of a racer

A naturally aspirated 4.0-liter, six-cylinder boxer engine that revs to 9,000 rpm is at the heart of the new model. Generating up to 502 hp and 346 lb-ft of torque, the engine offers extremely sharp throttle response thanks in large part to its six independent throttle bodies. This engine is virtually identical to the unit found in the new, track-only 911 GT3 Cup race car. The seven-speed Porsche Doppelkupplung (PDK) transmission – engineered and tuned specifically for the 911 GT3 - is included as standard equipment, while a six-speed manual transmission is also available to order for customers who prefer a particularly engaging driving experience. This engine, which was first introduced in the limited-production 2019 911 Speedster, has been further optimized for use in the new 911 GT3 with new pistons. A dry-sump lubrication system ensures a sufficient oil supply even at very high lateral and longitudinal loads by using a total of seven suction stages that quickly return oil to the external tank. Acceleration from 0 to 60 mph with the standard seven-speed PDK takes only 3.2 seconds and top track speed is 197 mph.

Lightweight materials

The free-revving engine is only a one part of what makes the latest GT3 such a standout. Based on the 911 Carrera body, front track width increases by 1.9 inches. Despite the change in size, the new model weighs almost virtually the same as its predecessor. This is possible thanks in part to a more extensive application of lightweight materials in the body than ever before in a 911 GT3. The hood, rear wing, and fixed rear spoiler underneath the wing are all made of carbon fiber reinforced plastic (CFRP). Lightweight, noise insulated glass on all of the windows also aids in accomplishing the ambitious weight target.

Chassis and brakes

Narrowing the gap between race and road cars even further, the double wishbone front axle of the new GT3 is derived from the 911 RSR and 911 GT3 Cup cars and adapted for road use, marking a major milestone in the history of the 911. The new front axle offers even more direct and precise steering than the predecessor. Cornering stability improves, allowing for higher cornering speeds and better mid-corner control over uneven pavement. As with past models, the rear axle uses a multilink design, but for this generation an even greater number of ball joints in both the front and rear are used, further enhancing the capability of the GT3 chassis. In fact, the new GT3 suspension does not share any parts with the current 911 Carrera models.

The standard braking system also boasts improvements over the predecessor model with cast iron discs measuring 408-mm in diameter on the front axle, which is a 28-mm increase over the previous generation. Despite sharing a diameter with the recently introduced 911 Turbo models, the discs used for the GT3 are approximately 17 percent lighter due largely to the use of a narrower friction ring. Porsche Ceramic Composite Brakes (PCCB) are also available as an additional cost option. The optional system includes rotors with a diameter of 410 mm in the front and 390 mm in the rear that offer weight savings of about half compared to similarly sized cast iron brake discs and significantly improved thermal load capacity. The ability to deal with very high heat is achieved primarily through special cooling channels in the brake discs as well as newly developed, highly efficient ventilation of the brakes.

GT-specific forged alloy wheels with a 20” diameter in front and 21” diameter in the rear contribute to the overall improvement in vehicle dynamics. The front wheels are half an inch wider than the wheels of the previous GT3, and gain an inch of diameter in the rear. Despite increased width, the new wheels are also about 3.5 lbs (1.6 kg) lighter in total as compared to the wheels on the preceding model. Customers may also specify pin striping on the wheel in either Shark Blue or Guards Red.

Complementing the new wheels, specifically developed ultra high performance summer tires that are 10 mm wider at both the front and rear, now measuring 255/35ZR 20 on 9.5J x 20 front wheels and 315/30 ZR 21 on 12J x 21 wheels at the rear. For drivers who desire an even more track-focused setup, Porsche is offering a street legal track tire – previously reserved for RS models – for the first time. These tires were used to complete the benchmark laps set at the Nürburgring.

The new 911 GT3 lapped the 12.944 mile (20.832 km) configuration of the most demanding track in the world, the NĂĽrburgring-Nordschleife, in 6:59.927 minutes. This is where the 911 GT3 demonstrates its capabilities in impressive fashion. During final testing, it lapped the NĂĽrburgring-Nordschleife, traditionally the ultimate proving ground for all sports car developed by Porsche, over 17 seconds quicker than its predecessor.

Aerodynamics

Aerodynamics also play a critical role in the improved performance capability of the new model. The new front fascia includes integrated cooling intakes as well as an adjustable front spoiler lip and an adjustable front diffuser that can be set up in stages for track use. Specifically developed side skirts optimize airflow around the wheels, but the most visually striking aerodynamic development lies at the rear where swan-neck connections support the rear wing, and a large rear diffuser is visible. As in the front, the rear wing is manually adjustable in stages ranging from settings intended for road use to positions intended for use only on tracks. Even in the “normal” position, aerodynamic downforce is up to 50 percent greater compared to the preceding 911 GT3. When the performance position, which is not intended for street use, is applied to both the front and rear, downforce increases by up to approximately 150 percent.

Interior

The connection to racing continues inside where a GT3 Multifunction Sport steering wheel with a 360 mm diameter and upholstery in Race-Tex is standard equipment. For the first time in a 911 GT3, the steering wheel also includes a drive mode switch, allowing the driver to switch between driver configurable settings by simply turning the dial.

Four-way Sport Seats Plus are included as standard, while 18-way Sport Seats Plus and carbon fiber Full Bucket Seats, the latter of which save roughly 26 lbs. compared to the standard seats, are available as extra cost options. While most of the interior is closely related to other eighth-generation 911 models, one difference in particular is plainly obvious: the gear selection lever. Specifically designed for the GT3, the PDK gear selection lever is based on an adapted version of the manual transmission gearshift lever. Unlocking it to change gear selections is possible by pressing on the shift pattern visible on the top. Additionally, this design allows for manual upshifts and downshifts without the use of the paddles.

There is also a GT-specific “Track Screen” function that reduces the amount of information in the screens surrounding the analog tachometer to the bare essentials and groups that remaining information closely around the central dial so that remains easily visible. Tire pressure and water temperature are always visible on the left, and on the right the display is individually configurable.

The Chrono Package continues to be available as an additional cost option. This feature, which differs from the Sport Chrono Package found on many other Porsche models, adds an analog stopwatch on the dashboard and a digital stopwatch in the instrument cluster. This also adds Lap Trigger support. The Lap Trigger, which is available through Porsche Tequipment, allows for very precise measurement of lap times that can be analyzed and compared on a smartphone using the Porsche Track Precision app.

Market launch and availability

The new Porsche 911 GT3 is expected to arrive in U.S. as a part of the 2022 model year, reaching dealers by Fall 2021. Market specific pricing and order availability will be announced closer to that time.
