V orhang on the for the new Porsche 911 GT3. The Erlkönige camouflage film is gone, now he's in the studio. Together with the first GT3 of the 996 series. Before you look back, first facts: the six-cylinder boxer engine of the new 991 GT3 has a displacement of four liters. The Porsche engineers have set new limits in terms of speed, power and aerodynamics: the four-liter boxer can turn up to 9,000 rpm shortly after generating 500 hp and a diffuser similar to that of the 911 R keeps the aerodynamics in balance.

911 GT3 with six-speed manual transmission

Perhaps the most emotional fact for sports drivers: There is again a six-speed manual transmission. As with the first 911 GT3. So raise the curtain for number one. It's been 18 years again.

Who would have expected such a success story in March 1999? At that time, the Porsche 911 GT3 presented itself in innocent arctic silver and with the not-so-popular fried egg headlights to the world press at the Geneva Motor Show. 18 years later the name GT3 stands for a sports car legend.

The lettering' 4.0 'is emblazoned on the wing supports of the rear wing - an indication of what is hidden here under the new CFRP trunk lid: Right, a six-cylinder naturally aspirated engine with four liters of displacement and 500 hp.

Psst, secret: new 911 GT3 for the first photos in the studio

The first GT3 of the 996 series with a sympathetically uneven idle is looking for its place in the Fo with a creaky boxer tostudio. The fact that we cannot celebrate his coming of age with a proper curve party on the race track is due to his great-grandson of the 991 series. At the time of the photo production it wasPresentation of the second generation of the 991 GT3 at this year's Geneva Motor Show has not yet run. The photo studio is therefore still similar to a high-security prison, as the current GT3 naturally wants to present itself to us without a camouflage film.

Who actually invented the legend 'GT3'? “I'm not the inventor of the GT3 story. The initiators were my boss at the time, Hartmut Kristen, our long-time motorsport boss, and Roland Kussmaul. The idea behind the GT3 development was not that we wanted to build a particularly great road car, but a homologation vehicle for racing, ”says Andreas Preuninger, who has taken over the project management for the Porsche GT vehicles from the second generation of the 996 GT3 and up until today holds. Nonetheless, he was of course also involved in the original design of the GT3.

“The Aerokit parts were already part of the series, and the rims come from the Exclusive range of accessories. The unique selling points of the first 996 GT3 were the bucket seats, which were developed especially for the car at the time. In addition, the back seat was removed and the GT3 was made more or less classically easy, ”continues the GT boss from the beginning of the GT3 history. For fans of numbers: The leather-covered bucket seats of the 996 GT3 saved around 20 kilos compared to conventional seats. The missing rear seat system reduced the vehicle weight by a further eight kilos.

996 GT3 weighs 1,350 kg

The 996 GT3 is not only necessary because of its weight of 1,350 kilos, but also for the little ones, but just love fine details. Another example of what from today's perspective looks like a shirt-sleeved weight reduction is the lack of a glove compartment. “Just leave it out” is no longer so easy today due to different process structures in development. In addition, the GT3 has become much more of an all-round sports car today, which is largely used by customers in everyday life.

“The first GT3 was more or less a car with components from the shelf and an engine racing that has been tamed for road purposes, ”Preuninger looks back. The 3.6-liter naturally aspirated engine was based on the engine of the Le Mans winning 911 GT1 racing car from 1998. The rated output was 360 hp. At that time, power was transmitted via a manual six-speed gearbox.

Six-speed manual switch and PDK for the new GT3

Hand switch, that was once upon a time? Think the great sports driver love is back! After the manual transmission became extinct in the first 991 generation of the GT3 and GT3 RS, the manual switch is now experiencing an emotional comeback in the second 991 generation. In addition to the standard seven-speed PDK, a manual transmission is now available again. We can already imagine how crisp the shift stick can be drifting through the alleys and how short the shift travel is, because the manual six-speed gearbox is well known -it comes from the 911 R.

Sounds like a holiday already, but it gets even better. The lettering “4.0” is emblazoned on the wing supports of the rear wing - an indication of what is hidden under the new CFRP trunk lid. Right, a six-cylinder naturally aspirated engine with four liters of displacement and 500 hp. In all honesty, we like to criticize at sport auto, but aren't those great times when the basic GT3 already carries a four-liter?

Four-liter boxer like in a cup racing car

“The engine is not only a massive further development compared to the 3.8-liter predecessor with 475 hp, but also to the four-liter from the 991 GT3 RS and 911 R. The new four-liter has a different crankshaft with a central oil hole. In addition, piston rings with a special coating are used to further reduce friction. In both the 3.8-liter and the four-liter RS ​​and R, the cylinder liners were not coated; now they are specially coated. Another innovation: We now have a rigid valve train. So far, we also haven't had a double switching suction system. The whole thing is already a package that feels noticeably different - more than the pure figures of 25 extra horsepower suggest, 'says Andy Preuninger enthusiastically about the new engine, which is also used in the new Cup racing car.

Speeds of up to 9,000 rpm

Similar to the 3.8-liter, the new four-liter is now turning to previously unattainable heights. While the four-liter of the 991 GT3 RS was allowed to rev up to a maximum of 8,800 tours, the speed limit of the new GT3 engine is now a phenomenal 9,000 rpm. Good news for handset fans: unlike in the 911 R, the speed limit with manual gearbox is not limited to 8,700 rpm, but - analogous to the GT3 version with PDK gearbox - up to 9,000 revs can be turned.

' The Porsche engineers have set new limits in terms of speed, power and aerodynamics: The four-liter boxer is allowed to turn up to 9,000 rpm shortly after generating 500 hp and a diffuser similar to that of the 911 R keeps the aerodynamics in placeBalance. ', Says editor Christian Gebhardt.

' The manual six-speed gearbox is the same as in the 911 R. But there is a new crankshaft for the If we use a flywheel that is no longer compatible with the single-mass flywheel, we now use a dual-mass flywheel. In the 996 GT3 and 997 GT3, there was only ever a dual-mass flywheel. In addition, a different lock is used in the new GT3 than in the 911 R. The lock values the R are 22/27 and the GT3 now 30/37, ”explains the GT project manager.

20 percent more downforce, same drag coefficient

Visually, the 911 GT3 became the Second generation compared to the predecessor at first glance only slightly modified, but inconspicuous detailed solutions should bring great advantages here. 'My motto when changing generations is always efficiency. The car has 20 percent more downforce than its predecessor, but has the same drag coefficient This means that the car has similar downforce to the 997 RS of the second en generation. New airblades are now helping on the front apron so that the flow on the side of the bow section is laminar earlier. This is how you can positively influence the drag coefficient, ”Andy Preuninger describes the first part of the aerodynamic changes.

The lettering' 4.0 'is emblazoned on the wing supports of the rear wing - an indication of what is hidden under the new CFRP trunk lid: Right, a six-cylinder naturally aspirated engine with four liters of displacement and 500 hp.

The rear wing is 20 millimeters higher and is 10 millimeters further back than on the first 911. “The The real breakthrough in terms of aerodynamics comes from the new sub-floor. The second generation has a rear diffuser derived from the 911 R, which the first generation did not yet have. We had to develop this rear diffuser on the 911 R because we had some problems getting the vehicle stable without a proper rear wing. Only the small extension spoiler would have been far too little on the 911 R. This led to the development of this diffuser. In terms of effectiveness, we have now been able to extremely increase the diffuser on the GT3 again. With the GT3 we haveinstead, there are air baffles behind the front wheels, which accelerate the air under the car towards the rear diffuser. This makes it even better, ”explains the GT project manager.

Finer steering feel on the front axle

Supertest: hand switch and PDK And what has happened on the chassis side? “New data sets are being used for ABS and rear-axle steering. A lot has also changed with the front-axle steering. The hardware is actually the same, but the basic layout of the software structure is now derived from the 911 R. The steering is virtually a further development of the R characteristic. In our specification sheet it was stated that we wanted to find even more feeling in the steering. “Sounds delicious, we are already looking forward to the first turning maneuver at the limit.

While the spring rates remained unchanged, the dampers were reapplied . “Even harder bearings are now being installed in the lower wishbone. Especially when changing lanes quickly over 250 km /h, the car is now even smoother on the front axle. What is also noticeable is the residual comfort behavior, which is even more confident. And yet you are even faster with the car on the racetrack, ”says Andy Preuninger.

So the super test can come. Small idea from us: This time we're producing the super test with two GT3 test cars. We are celebrating the GT3 handset for the connecting stages on the country road and the autobahn between Stuttgart, Hockenheim and Nürburg. If the clock is running on the racetrack, the GT3 with PDK comes back into play to chase the best time.

The new Porsche GT3 can be ordered immediately at prices starting at 152,416 euros - initially only with PDK. Fans will have to wait until September for the handset option.
