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:

The 2014 Porsche Cayenne Turbo S brings 50 extra ponies to Detroit

Porsche has announced a new version of its popular SUV today at the Detroit Auto Show: the 550-horsepower 2014 Cayenne Turbo S.
This newly minted "flagship" of the Cayenne lineup is powered by a twin-turbocharged 4.8-liter V8 engine, and offers 50 hp more than the Cayenne Turbo. Performance figures are impressive for the sleek utility vehicle: 0-60 miles per hour can be dashed off in 4.3 seconds, while maximum speed is rated at 175 mph. The Turbo S also gets dynamic chassis control, torque vectoring and Porsche's Sport Chrono package - all standard equipment.
Visually the Cayenne Turbo S differentiates itself from the lesser models in pretty subtle ways. Gloss black trim decorates the gawping front air intakes, as well as rear-view mirror trim panel. The SUV also wears 21-inch Turbo II wheels, a la the 911 Turbo.

Next-gen Porsche 911 may include plug-in hybrid version

According to Auto Express, there's a plug-in hybrid Porsche 911 on the way, and it could arrive as soon as the introduction of the next-generation car. At the Detroit Auto Show, the UK outlet spoke to 911 product line director Dr. Erhard Mossle, who said the Stuttgart automaker was "working on different solutions" for the next iteration of its most iconic car, and, "of course, we are discussing plug-in solutions for the 911, but there are a lot of things to solve with packaging in the car and other things to solve. It will maybe be in the next generation, yes." "When we see the 911," he said, "we see the plug-in hybrid as a performance car." Since we just saw the introduction of the turbocharged powerplant in the 911 Carrera last summer, we can expect a wait of at least four years for the next powertrain evolution. Mossle said that any 911 PHEV would remain a sporty proposition and likely retain the flat-six engine, which would give more prestige than the four-cylinder 718 (Cayman and Boxster) yet still be able to satisfy emissions regulations. Mossle is echoing the comments made by Oliver Blume, chairman of the executive board at Porsche, at the Detroit show when Blume said the production version of the Mission E concept would be a sports car that happens to be electric. As far back as 2009, in fact, Porsche has been openly discussing an electric 911, the caveat even then being that it has to perform like a Porsche while providing decent range. In the middle of 2014 it was reported that the carmaker might make a 700-horsepower 911 Turbo S hybrid, by the end of 2014 it was reported that the automaker wouldn't make a 911 hybrid. A year after that first report, a 911 hybrid was back on, using the E-Hybrid system supposedly dismissed six months before, and then last November we got spy shots of a 911 with a supposed PHEV port. But with its Mission E work, and being designated to lead the Volkswagen Group's R&D into performance hybrids, a battery-boosted 911 might finally make sense. Related Video:
