Exclusive First Drive: 2014 Porsche 911 GT3
Tradition and progress collide.

By Jason Cammisa April 29, 2013 / Photos by Tobias Hutzler


At this spring's Geneva motor show, there were crowds fighting to snap pictures of the newest fast cars from Lamborghini, Ferrari, and McLaren. Over at the Porsche stand, a drop-dead gorgeous 911 GT3 sat in relative solitude, receiving only passing, disapproving glances.

The proverbial pitchfork-wielding Porsche purists weren't pissed just because the new car no longer uses the Le Mans-winning Mezger engine of previous GT3s. No, the nail in the newest Porsche's coffin of public opinion is that it will be available only with an automatic transmission. Which is, by the way, no different from the crowd-pleasers over at Lamborghini, Ferrari, and McLaren.

"I don't get this Stone Age idea about what a 911 should be," says Andreas Preuninger, the man responsible for Porsche's GT cars, at Porsche's rain-dampened proving grounds the next day. "With the first GT3, they were practically throwing rocks at me because it didn't have an automated-manual transmission, which was where all the hype was at the time. But those transmissions weren't very good. Now, the GT3 gets a perfect [dual-clutch automatic], and everyone is screaming for the manual."

We admit that, this time, we were part of the screaming. The GT3 has always been the 911 that offered the least of what techno-crazed Germans would call "progress," but as a result, it led the sports-car world in terms of driving experience. It was the rawest, purest expression of everything that defines the 911—right down to its detuned race motor and wrist breaker of a manual shift lever.

"Ugh, God, you're one of them!" says Preuninger, rolling his eyes. "Just shut up and drive the thing."

The new GT3 starts up with a bark no less intense than that of the old car. The interior buzzes, both literally and figuratively, at idle. The variable-stiffness magnetorheological engine mounts are clearly not tuned for comfort. When you start out from a stop, there's an overabundance of revs, noise, and clutch slippage. Our test car is a preproduction prototype, but if Porsche has any sense, the transmission's programming will stay exactly like this.

Moving off, as you're focusing on the clutch engagement, something else grabs your attention: The steering snaps to life. This doesn't happen in a regular 911, with which the GT3 shares its steering hardware. It took Preuninger's team more than two years of programming work before he was happy with the electrically assisted steering; he wanted the driver to feel everything the car's tie rods experience. This is doubly good news, as it means the GT3 has steering reminiscent of older Porsches, but it's also an indication that there's hope for the regular, numb-helmed 911. And the Boxster/Cayman twins, which use similar equipment.

Cruising at U.S.-highway speeds on Porsche's track, the GT3's steering isn't quite as talkative as that of a 997. Still, given how distant the steering in the base Carrera feels, it's a miracle that it talks at all. And the weighting is genuinely natural when you turn into a corner. On this slick surface, we could almost criticize the steering for not communicating enough as the front tires lose adhesion. Except the rear tires let go at the same time. Understeer is nowhere to be found; at the limit, the car goes neutral. Stability control is very lenient, interfering only when the driver doesn't correct as quickly as the rear wheels come around. And when Preuninger, sitting in the passenger seat, switches off the system with a devilish laugh, the GT3 becomes as throttle-steerable as every GT3 before it.

Then there's the active rear steering. Frankly, Porsche's marketing department should have left that out of the press conference. You'll never know it's there. You'd hardly describe the previous GT3's reactions as ponderous, but the old car did take a moment to settle into a corner, especially at the rear. The new car turns in instantly and as a whole, with none of the artificial feeling imparted by the regular Carrera's optional active anti-roll system. Preuninger meant it when he told us to shut up and drive: Even the sharpest purist rhetoric falls apart when the GT3 feels exactly like a 911 from behind the wheel, only better.

And don't bother crying over the disappearance of the Mezger motor. This car uses effectively the same 3.8-liter block as the Carrera S, but that tremendously oversquare engine's bore and stroke dimensions are each within a millimeter of the last GT3's 3.8.

The new engine hits its power peak where the old one hit its rev limiter. It redlines at 9000 and makes 475 hp from just 3.8 liters. Shut up, indeed.

Along with additional oiling capability, the GT3 engine uses titanium connecting rods and forged aluminum pistons. Its cylinder heads have been substantially reworked for high-rpm duty, including nerd-**** finger followers that incorporate hydraulic valve-lash adjustment. Happily, this six isn't as soft in the low range as its 6250-rpm torque peak would suggest. It lives to rev, though we had to fight the instinct to shift shy of redline. That's probably because our ears have never before been treated to the sound of a nine-grand flat-six in a street car, but forward thrust eases noticeably in the 750 rpm between the horsepower peak and the redline. Noise does not. The GT3 emits a pained wail that, along with the high-pitched whine from the transmission's hydraulic pump, will have a Ferrari 458 looking around nervously for the nearest exit.

To grab the next gear, you can pull one of the steering-column paddles, which feel heftier than those of a regular 911. Or, if you're in the middle of a turn, sideways and arms crossed up, you'll want to use the console shifter, because the paddles aren't fixed to the steering column. And there's even more good news: By reversing the shift pattern, Porsche has finally admitted—without actually admitting anything—that its Tiptronic (torque-converter automatic) and PDK (dual-clutch) shift levers have been backward for years. The GT3's lever now operates like a sequential race 'box, with a push forward for a downshift and a pull for an upshift.

The seven-speed transmission contains revised gearing compared with the regular 911. Every single ratio is different, as is the final drive. A quick calculator workout, however, shows that while the ratios are much shorter overall, the GT3's additional 1200 rpm makes up for the gap—the car's maximum speeds in gears one through five are nearly identical to those of a Carrera S. The additional grunt and shorter gear ratios knock a staggering 0.7 second off the Carrera S's already blistering sprint to 60 mph. Fuel economy will likely suffer, but we don't care, and you shouldn't either.

More important, the GT3 hits its top speed in top gear (and at just over 8000 rpm), where other PDK-equipped Porsches do the deed in sixth. The GT3 also reacts more quickly to shift requests than does the regular 911, and Preuninger even installed a clutch-dump function—pull both paddles in any gear, and the engine will freewheel. Release them, and drive will gently reengage. If you're in Sport Plus mode, the gearbox will unceremoniously dump the clutch.

"I wanted to make sure I could still do a burnout when I pull up next to a Prius at a red light," Preuninger says. The man is quickly approaching sainthood.

Alas, the GT3 wouldn't need the Prius-paddle function if it had a real clutch pedal. Hearing this, Preuninger's chiseled face drops.

"The manual-versus-PDK argument was the most discussed point [during development], and we only made the decision to go with the PDK last August. This is genuinely the first time a paddle gearbox is satisfying to me. PDK takes away the clutch, which is the interface between man and machine. I admit that. But it gives back more. Every shift of the manual-transmission car loses almost a half car-length [on acceleration]. That means after three shifts, the [automatic] GT3 can pass a manual GT3 and pull safely in front of it."

To which we couldn't help but respond, "Yeah, a GT2 or an automatic Turbo could do that, too."

The crux of the issue is that there's a fundamental difference between speed-obsessed German engineers and good ol' silly Americans who just love to drive a manual. For the former, there's a point at which the automatic is faster and can be programmed to be more efficient. It then becomes "better." To the rest of us, it merely becomes a better automatic. And while the GT3's PDK is one of the better automatics, there is not, nor will there ever be, an automatic that is as involving as a manual. The 911, like so many other cars, has traded a degree of involvement for speed. We'd happily lose time on the sprint to 60 mph, or a few seconds per lap, if it meant more fun.

But rather than lay all the blame on Preuninger and Germans as a whole, we're partly at fault. There was a time when most enthusiasts seemed to view the dual-clutch automatic as the second coming. After living with those transmissions for a decade, they just feel like automatics.

On that note, allow us to apologize on behalf of an entire industry. We were wrong. We don't care about shaving tenths off acceleration runs. We want to work for our lap times. We're bored to death behind the wheel, and we want to get busy with a shift lever and a clutch pedal.

Perhaps those Germans also can admit they made a mistake. No need to apologize for the directional operation of the shifter or the regular 911's lack of steering feel; those are now fixed.

You have to hope that, at some point, Porsche will release a Mea Culpa Edition GT3 with a six- or seven-speed manual. In the meantime, we'll just enjoy the version we have. Which—if you'll please just shut up and drive it—is one hell of a consolation prize.

 

Great article and I couldn't agree more with the writer and his comments on speed versus involvement.

 

Same here. Unless you are racing where a lot of $$$ is involved, who care's about the half-car-length difference between manual and automatic? Manual is just plain more fun.

 

why is the option just not there is my gripe!
GIVE US A CHOICE!
I expect it in the 991.2
waiting until then

 

My feelings exactly. Offer the dammn manual.

Fantastic article. Im glad they shared my opinion at the end of the article.

 

I like this Preuninger guy.

I dislike the lack of choice, but it's completely understandable.

 

Not going to happen guys....This is a done deal and no going back.

 

This is absolutely the crux of the issue and where Porsche has lost the script on this latest GT3 IMHO.

High performance cars have become so fast as to be virtually unuseable on the street in any real sense of their potential. And despite Porsche's omnipresent hype about this being a track car, anyone actually trying to shave tenths in a stock GT3 is playing Russian Roulette. Remember these cars are faster than top level sports racers of just a few years back yet have none of the integrated safety systems such as rollbars, six-point harneses, and fire suppression systems necessary for protection at those speeds. Add to that the fact that Porsche voids your warranty the minute you set foot on track and it quickly becomes apparent that the Nurbugring lap time game is just a marketing ploy.

For years the GT3 has carved out a niche as the antithesis to the techno-supercar. It was the go-to choice for those seeking the rawest, purest, and most engaging driving experience. Not sure what prompted Prueninger to do an about-face on his disdain for automatics and I have no issue with it being offered on the GT3, but the fact that a manual is not offered as well is major fail.

No manaual = no sale.

 

Although I agree with you regarding the speed without safety measures, I disagree that there is a global voiding of a warranty, once a car is driven on track.

Usually warranty statements include ~ "anything that breaks while on track, or high speed event, etc... is not covered". So basically, if nothing fails while on track, you're good. If something fails after that, and if not caused by previous track use, you should be covered.

 

Please refer to first paragraph of pg4: http://www.porsche.com/all/media/pdf...l_GT3_PCNA.pdf

I read that as being on your own when on track. Certainly your choice to interpret it different.

 

"The file you are trying to access cannot be found."

But, I believe your interpretation is correct. If anything breaks while on track, it is on you. After that, this is not the case (unless there was a direct cause of failure while being on track). And there is certainly not a global voiding of any warranty. If you run a 1/4 mile, and then your paddle shifter button breaks off 4 months later, I don't see this being denied...

Or if you've attended a weekend long HPDE, and then your door speaker fails..., etc...

 

Regarding the comment about clutch slippage. If there is slippage every time you drive off would that imply premature wear ... wonder how that would compare to a manual where clutch failures are not common, unless abused.

 

I don't know about North America, but here, my dealership sent me a letter regarding tracking my car.
It basically stated that prior to tracking it, I need to take it in to the dealership so they can make sure all the parts are ok for tracking, and then bring it back again afterwards to change out any parts that may have been worn out.
The check up is free I would assume (usually is), parts that got worn on me (like the center lock, brake pads, tires).
but nothing regarding voiding my warranty, they encouraged me to track it.

 

This is not too uncommon... This practice verifies if parts were messed before, during, or after the track event. I see it as a good idea.

 

I think he just acceped that he has no choice and is trying to keep an open enough mind to give the new car a fair chance . It's hard to review a car if ones bias is present before he even drives it .

I agree with you on the choice .
