992 Porsche 911 GT3 first details – 510 hp, naturally aspirated, PDK or manual, better aero, no weight gain

We are probably a few weeks away from the unveiling of the new Porsche 911 GT3, but several selected European media have already been invited to ride in the prototype. These publications, such as Trainer, announced the first details of a sports car that is biased on the track, revealing impressive technology for race cars.

First things first – although it uses the latest 992 as a base, the GT3 carries the engine of the current car. Despite early rumors of a turbocharged grinder, the new car is powered by the same 4.0-liter naturally aspirated flat-six as before, albeit with some modifications. Zuffenhausen GT boss Andreas Preuninger cited a 510 hp figure, which is the same as the 10-hp Speedster model on the old GT3.

It’s not exactly the same engine as the Speedster, however, as the GT3 needs to adopt stricter noise and emissions regulations, so a lot of work has been done to ensure that the outputs remain intact. The good news is that the engine that stands out is still capable of reviving up to the stratospheric 9000 rpm.

The drive continues to be sent to the rear wheels either via a six-speed manual transmission (right for purists!) Or a seven-speed PDK dual-clutch transmission. The latter has one less gear than the standard 992 and comes with a suitable mechanical lever instead of a weak electronic switch.

Despite the larger 992 body, the new GT3 will weigh the same as before, thanks to a new carbon fiber hood that joins the usual weight-saving features. This includes lighter materials, thinner glass and rear seat removal, and some noise insulation. “I did not want the car to be heavier. That was critical. “It has to be bigger because now I have a 992 body, but I do not want to carry more weight,” Preuninger said.

The list of GT-specific components extends into the chassis, where the multilink rear suspension and rear-wheel drive are raised from 991.2 GT3. The front, however, is new and uses dual bone mounting (instead of McPherson struts) with components taken from the Cup and RSR race cars. The car has been stripped of its rubber bushings and has springs that are 25 to 30% stronger than before.

The wheels are also taller and wider than before, now have a diameter of 20 inches at the front (with 255/35-section Michelin Pilot Sport Cup 2 tires at the front) and 21 inches at the rear (with 315/30-section tire)) New rollers Y-sound central locking conceals larger 408 mm front brake discs and 380 mm rear brake discs, which feature a racing-style round surface instead of cross-drilling.

Complete reengineering is hidden beneath the revised aerodynamic package that takes the GT3 even further in motorsport. At the front, you have a much wider central air intake that blows air into the radiator, allowing air to pass through ducts that have shifted from the bumper to the bonnet.

But it is the rear of the car where the new GT3 looks most extreme. This is where you will find a dramatically different wing from the swan neck, which is placed at the top rather than the bottom. This new design cleans the air flow under the air foil, improving its efficiency and increasing the power produced. A large diffuser continues to characterize beneath it, framing the exhaust from the center.

Overall, Porsche claims that the new car produces 50% more power compared to the outgoing model, without a corresponding increase in traction. Of course, you can still get the GT3 as the Touring, which will continue to come with a retractable spoiler, instead of the giant wing, for a smoother look. This particular model will also no longer be just manual, available for the first time with the PDK option.
