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 CEO Matthias Mueller throws hat back in ring for VW CEO job

Toward the end of February it got leaked that Porsche CEO Matthias Muller was being promoted to Volkswagen's supervisory board. Muller's credentials and his success over 36 years at the VW Group have, for observers, put his name in the pool of potential candidates to succeed current group CEO Martin Winterkorn when Winterkorn retires in two years. But the 61-year-old Muller told German newspaper Frankfurter Allgemeine Zeitung earlier in February, "It's no solution to put a 63-year-old at the head of Volkswagen," and the statement was taken to mean he wasn't considering the job. Muller now says the quote was misunderstood. In a report in Automotive News, the newly minted board member says he was commenting on what it would mean for the supervisory board and the Group if they nominated a 63-year-old to replace a 69-year-old - that it wouldn't result in a "generation change." However, if that's what they choose to do, Muller feels great: "I stand ready to take over any assignment," he said. Muller's name re-enters the candidacy pool, but we still have no idea who leads the running for the role and Winterkorn isn't saying a word. It could be three years before we know: Winterkorn's contract concludes at the end of next year but there is speculation he'll re-up for two years to see out the end of the Strategy 2018 initiative.

Ex-F1 driver Mark Webber has tough life, shakes down Porsche 911 GT3 RS

It's good work if you can get it, and Mark Webber has got it. The works driver for the Porsche World Endurance Championship Team was apparently asked to moonlight in a video shoot for the company's new 911 GT3 RS at the Nurburgring Nordschleife, and what do you know, he complied. They don't appear to be going too quickly, and a racing driver asked to rein in what will be one of the most blistering cars we'll see this year must be very serious work, because Webber doesn't appear to be smiling at all. We'll guess there's a big smile on the inside, though, and some tales to tell to his Porsche teammates at the next WEC race. Maybe the next time we see the 911 GT3 RS at the 'Ring, it will be doing the timed lap we're all waiting for. Related Video:
