Porsche 911 GT3 RS getting all-new atmospheric engine

Porsche surprised many of its most puritanical enthusiasts when it took a decidedly more usable approach with the current 911 GT3. But when the new GT3 RS debuts, it promises to be a much more extreme departure. And a big part of that comes down to the engine. At the Detroit Auto Show this week, Auto Express spoke with Porsche R&D chief Wolfgang Hatz – who also happens to be head of engine and transmission development for the entire Volkswagen group. Hatz revealed that Porsche has developed a completely new engine for the GT3 RS, and while previous rumors suggested the RS would go turbo to fill in for the lack of a GT2 (and make the most out of its displacement), Hatz confirmed that it will be naturally aspirated. Considering that Porsche rarely goes downwards when it comes to 911 engine displacement, only upwards, we'd expect the new RS to pick up where the previous 4.0 left off. The new GT3 RS is also expected to pack a more extreme suspension, aero and stripped-out interior, but those hoping for an old-school approach may be disappointed to learn that the new RS will (at least at launch) only be available with the seven-speed dual-clutch transmission – though a manual version could follow if there's enough demand. In a related development, Hatz also hinted that the Cayman GT4 could debut at the Geneva Motor Show in March, with an even more extreme approach than the previous Cayman R. The new top-of-the-line Cayman is reportedly being developed to comply with GT4 class racing regulations but be fully homologated for road use. Related Video:

Porsche says turbo'd 911 engines will still be revvy

Porsche fans really, really don't like change. Remember when the 911 moved away from air-cooled engines? Now, as the company prepares to move the vast majority of the 911 line away from naturally aspirated powerplants, one of the brand's highest ranking officials is speaking out to prevent a similar outcry. Dr. Heinz-Jakob Neusser, the head of powertrain development for the Volkswagen Group and a board member of the VW brand, told Car that turbocharging won't take away from the rev-happy nature of Porsche's current engines. "Turbocharging is possible with higher revs – it's not true to say that turbocharged engines must stop at 6000rpm," Neusser told Car at the 2015 New York Auto Show. "That's not true... If you look at McLaren, they already have in production turbo engines with high revs." With turbocharged engines, Nuesser explains, there's no need to go for a super high redline, because engineers are trying to spread the torque over the entire rev range. "It makes no sense to go to 10,000 rpm with a turbocharged engine," Neusser told Car. The other big concern that comes with the switch to turbocharging focuses on the 911's iconic flat-six exhaust note. Maintaining the car's well-known acoustic character shouldn't be an issue, Neusser said. "Noise is not a problem," adding that the Volkswagen Group knows a thing or two about building sweet-sounding turbos. "Look at the 911 Turbo; it has an extremely expressive noise today – that is not a problem. At the other end of the scale, the Golf R has it too," Neusser told Car. "You won't miss character with turbos, I promise." According to Car, the new turbocharged engines will arrive later this year at the 2015 Frankfurt Motor Show, as part of the current 911's facelift.

Porsche 911 GT3 RS revealed in patent photos

Porsche has been taking its time developing the most hardcore 911 models for the latest 991 chassis. While the GT3 has been on the market for a little while, it suffered from some teething issues. The 911 GT3 RS is certainly on the radar since being spotted testing, but it's always better to get a look at a new car without all of the camo to hide the coolest parts. Thankfully, Car in the UK has some patent photos of the RS ahead of its debut, and they show off one mean-looking 911.
The first thing that you notice about the RS is that Porsche clearly isn't afraid to rework the latest 911's shape for its track-focused version. Each piece is slightly resculpted to squeeze the most out of it. Up front, the air dam has the same shape to the earlier photos. They also both highlight the upcoming model's tiny air inlet at the tip of the hood, the massive intakes in the rear fenders and general design of the rear wing with a ducktail underneath. The bubbled roof is much clearer here, where it was disguised in spy shots. You can also spot the slashing fender gills behind the front wheels that are a completely new feature.
The GT3 RS is the ultimate naturally aspirated 911 for the street, but according to Car, Porsche aims to take that even farther with the latest model. If these are the looks, then it's working. Unfortunately, the new version's powerplant remains a mystery. Though, given all the changes to the bodywork, the engine is almost surely getting tweaked over the 475-horsepower GT3. The RS is rumored to hit the road and be screaming down the track in 2015.
