"Porsche 911 GT3 gains manual gearbox and 9000rpm redline..."
(7 March 2017)
The revised Porsche 911 GT3 is regaining a manual gearbox option, following criticism that the current car has been offered only with a seven-speed PDK dual-clutch automatic gearbox since it was launched in 2013.
The revised GT3 uses a 493bhp 4.0-litre flat six, replacing the 469bhp 3.8-litre flat six. It is a development of the engine used in the 911 R and GT3 RS, with an upgraded valve train, a stiffer crank, low-friction cylinder liners, a new cylinder head design that dispenses with hydraulic valve adjusters and a 9000rpm redline - 750rpm more than the RS. The difference is “a quantum leap”, according to Porsche GT boss Andreas Preuninger.
“It is an absolute dream,” Preuninger added. “It has the ability to rev explosively. This is a unique selling point.”
With the seven-speed PDK gearbox and launch control, the new GT3 will hit 62mph from rest in 3.4sec and reach 199mph. The six-speed manual version is slower off the line, at 3.9sec to 62mph, but can hit 200mph.
Porsche has learned lessons from the 911 R that have helped to increase downforce on the new GT3 while reducing drag. An evolution of the R's underbody aero has been adapted for the GT3, while the fixed rear spoiler is mounted 20mm higher and 10mm further back to reduce drag and now works in partnership with the diffuser and underbody vortex generators. Preuninger claimed downforce at top speed is increased by 20% overall without any increase in drag - no mean feat, he said.
The adjustable PASM dampers now have a wider operating range, bushings have been stiffened for greater steering precision and the rear struts now feature weight-saving 'helper' springs.
As a result, Preuninger said the new car is both more comfortable on the road while even sharper on a circuit. This is important, because switching to the PDK ’box made the GT3 more attractive to a new range of customers who use their cars daily, not just as track day toys.
The interior gets the revised PCM infotainment system from the facelifted 911 range, complete with Connect Plus module and smartphone-ready Track Precision app to help you to analyse your circuit performance. There's also new scope to liven up the typically functional interior, including carbon-framed race seats and the option of a ‘3D’ colour-coded Alcantara stripe on the upholstery.
Weight-saving measures include reduced soundproofing. Adding structural reinforcement to the body-in-white meant weight had to be shaved off elsewhere to maintain the 1430kg kerb weight of the first-generation car. The manual version is 10kg lighter still. More weight loss can be achieved by opting for the PCCB carbon-ceramic brakes.
Pricing has not yet been announced, but Porsche expects demand to outstrip supply.

Porsche Chairman claimed 3.2s/100kmh whihc is making sense, while web site claims 3.4..... which is equal or similar to previous one ..... Strange.
Overall no surprise, the 500PS tag was psychologic. The price tag is also in increase : 154k base, but with PCM into it and leather , so overall this is an increase but specialist will tell you in fact appple to apple how much it is :-)
Red color is not the best choice according to me. I would have loved to see this new Blue/grey.
More to follow I guess :-)
Rgds,

The engine is fantastic And I am sure we will see more of it .
The difference in performance time 0 to 100 km/h is much bigger between the manual and the PDK then I would of have expected . If I had to order I would be in serious trouble .

aha. i never realized that.....

I wanted to wrote about it as well but, you were faster.
All in all a fantastic sportcar. I am getting it for sure, PDK-S one.
KresoF1:Car is not a limited production. Waiting list is (or will be) pretty long, but if you are interested enough you will get one for sure.
Even in the UK. Its a lottery always getting a GT here ??

Kobalt:wantone:112k UK price? Any ideas if it is a limited production or anybody can get a car?
From the Autocar article in post above:
"Pricing has not yet been announced, but Porsche expects demand to outstrip supply."
Any idea which part of the car is constraining the supply? Are those produced on the same lines as the non GTs?
997.1 C4 Silver (current), 996.1C4 (sold), 997.1C2S (sold) 986.1S (sold)
Jeannot:Any idea which part of the car is constraining the supply? Are those produced on the same lines as the non GTs?
I wonder if not this is just marketing talk. It would stupid of them to build more cars then they can sell. And no cars are built without an order (I assume).

Kobalt:^ FWIW: Here's the tach from the Evo video:
Dry-sump lubrication
Motorsport principles are also applied to the engine’s oil supply. Continued lubrication is vital, especially at very high engine speeds of up to 9,000 rpm and under the effects of the particularly high lateral and longitudinal acceleration that can be experienced on the racetrack.
Seven scavenge pumps in total return the engine oil quickly and efficiently to the external oil tank. Together with a new oil pressure pump offering fully variable displacement, optimum oil pressure is assured in all operating conditions. This system provides reliable lubrication of hard-working components and increases the robustness of the engine under heavy use on the racetrack.
Also new is the particularly efficient supply of oil to the heavily loaded connecting rod bearings. This is realised by a central oil feed into the crankshaft. Another innovation sees the oil efficiently defoamed by a centrifuge before it is delivered to the separate oil tank. This engineering solution originates from high-performance motorsport and is also used in the Porsche 919 Hybrid, an LMP1 class competitor.
The new 911 GT3 is factory-filled with Mobil 1 fully synthetic high-performance engine oil. The excellent lubrication properties of this oil ensure a reliable cold start, even at very low temperatures, and contribute not least to the durability of the engine.

"New Porsche 911 GT3 - Geneva 2017"
500hp at 9,000rpm and a manual gearbox option? We'll take a piece of that...
(7 March 2017)
No turbos, a 9,000rpm redline from a 4.0-litre flat-six, 500hp and a no-cost manual option. Yes, Porsche has responded to outcry over the 991 GT3 and limited availability of the manual-only R and given fervent stick-shifters the opportunity to put their money where their mouth is.
Will they? The sales split will make interesting viewing but the bigger story with this new GT3 is actually its engine, the most exotic, highest revving and most extreme version yet of Porsche's current Motorsport flat-six with a power delivery promising to make the RS feel a bit diesel-like in comparison. Put it this way - where that car reached its peak at 8,250rpm the new GT3 has got another 750rpm to go.
Welcome back old friend!
PH was lucky enough to get the full geek-out on the new GT3 with Andreas Preuninger ahead of the show reveal. And after an hour's private audience it's safe to say he's not kidding when his recurring theme is "more than meets the eye". Want the full, unexpurgated transcript in its near-6,000 word glory? Not a problem - you can read it here. Here, in the meantime, are the (slightly) edited highlights.
500hp is the headline, the PDK version a token tenth quicker to 62mph than the gen one GT3 and a smidge faster at the top end at 199mph. With one ratio less and the lack of launch control the manual is half a second slower to 62mph at 3.9 seconds but pulls a small extra margin at the top end to record 200mph thanks to reduced mechanical losses. Despite weight increases to the body in white the overall DIN kerbweight (minus driver) remains at 1,430kg even with all the four-wheel steering and other gubbins.
The manual is 10kg lighter and gets a mechanical limited-slip diff rather than the fully active one integrated into the PDK transmission. It doesn't get the lighter single-mass flywheel of the R but Preuninger's enthusiasm for the way it'll pick up from as low as 2,000rpm and rev - in his words - "explosively" through to the 9,000rpm redline is utterly infectious. Granted, some owners of early 991 GT3s may cock an eyebrow at his choice of adjective there. But we'll work on the basis that that particular flaw has been dealt with this time.
That's peak power at 9,000rpm too...
More on the engine though. New features include a stiffer crank (hence no single-mass flywheel) with central oil feed to the bearings, new ram air intakes and low-friction cylinder liners. But it's the new head design Preuninger is most excited about. Ditching the hydraulic valve adjusters means lower oil pressure, reduced stress on the valvetrain, less friction, less inertia and a simpler mechanism for operating the valves. Which basically equates to more revs and more power - up to 9hp alone from the new mechanical design.
With the finger followers now operating the valves directly the clearances are shimmed when the engine is built ... and that's it. "We ran one engine on the dyno for 300,000km and it did not change, not one half of a tenth," says Preuninger. "And we did it several times - owners do not have to worry they have to go to the dealer every 10,000km to adjust the shims!" Here's hoping.
"The car really goes," he grins, quite possibly understating things somewhat. "The 4.0-litre displacement really helps with the mid-range 'snap' but if you are in a 180-degree bend and have maybe 2,000rpm when you go on the throttle the bandwidth of revs is just mind boggling!"
The seven-speed PDK is updated from before with even faster shifts and new software. The manual is the six-speed from the R, which is no bad thing with its closely stacked lower ratios and short-throw shift. Preuninger accepts it is slower round the track than the PDK but satisfies the "new found niche" for purists seeking a more immersive experience. "We will satisfy the demand of all those people who didn't get an R, and this is I think the right way to do it," he says, pouring a hefty can of petrol on an alreadyheated debate.
Weight remains at 1,430kg without driver
Further R influence can be found in the improved aero. You'll see the reprofiled (and lighter) front bumper; new blade-like surrounds to the intakes reduce drag and smooth the airflow over the sides while underneath there are fences and vortex generators developed for the wingless R to speed the air going to the rear diffuser. As a result the fixed wing can be moved rearwards by 10mm and up by 20mm to reduce drag, sharing the workload with the diffuser. Result? 20 per cent more downforce at top speed - equivalent to a gen two 997 RS in fact - with no increase in drag coefficient.
Elsewhere the changes are more detail than those made to the powertrain and aero. Brakes remain standard steel (380mm on both axles) or PCCB with 410mm front and 390mm rear - Preuninger says braking performance is the same but PCCB's reduced unsprung weight is worth having. And that they look cool. The PASM dampers have been revised with a greater bandwidth between comfort and Sport settings, RS-inspired helper springs on the rear struts a further upgrade. Stiffer front bushings are fitted to improve steering response and the EPAS has been recalibrated too. "On the gen one it was great, on the RS even better and on the [Cayman] GT4 super cool," says Preuninger. "Everyone commented it was a dream on the R and this is the next step in feel and feedback, the best we've had so far."
Hopefully this lip can be removed...
Trim updates include '3D' Alcantara on the seats, a new red rim on the wheels and, naturally, the updated PCM from the facelifted 911 range. Overall the look is cleaner and relatively underplayed for a GT model, perhaps closer in spirit to the original 996 versions. But under the skin it sounds properly wild.
Meaning you're going to have to hurry if you haven't already started the charm offensive with your OPC, the official RRP of £111,802 sounding almost reasonable when you consider a Carrera 2 GTS coupe starts at £94,316 and could easily be in the same ballpark with a few options. Official line is production isn't capped by anything beyond capacity, equivalent to around 4,000 units of the gen one. Hardcore or not, the GT3 is now more accessible to a broader range of customers than ever before though. So you can expect demand to comfortably exceed supply.
But the big question. PDK or manual?
