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:

Car Club USA: Porsche Club of America Escape to Rushmore

The Porsche Club of America, whose motto is "it's not just the cars, it's the people," plans its annual Escape in a different city every year. This year's was particularly epic, as Porsche fans headed to the Black Hills of South Dakota for their gathering. The scenery and the history are part of the attraction, but the winding roads are the real headliner. "This road right here is the reason why we chose the Black Hills of South Dakota to do the 2015 Escape," said Ron Johnson of the Nord Stern Porsche Club as he navigated the mountain range. "These Porsches really love these twisty, curvy roads." That statement neatly sums up why the sports cars have resonated so deeply with their owners and enthusiasts for so long. In addition to the guided tours and drives around the winding terrain, the club hosts a car show. This year marks the club's 60th in the United States, and the Escape drew a wide range of Porsches of all vintages. Lloyd and Donna Nelson from Valley City, ND, arrived in their 1955 Porsche Speedster, which they purchased alongside a 1951 coupe in 1964 for a grand total of $750. Needless to say, it was a good investment – although they didn't know it at the time. "We had two children, one on the way, we were both working and I really didn't see the sense in two old cars," explained Donna. "I said, 'one of them has to go,'" to which Lloyd responded, "which one of the kids?" They sold the coupe long ago, but the speedster is still gorgeous and gets more than its fair share of stares and use. Will they win best of show? "This is what us as enthusiasts dream of," Johnson said. Watch the latest episode of Car Club USA to see how it turns out and for a snapshot of life at the Escape. Each Car Club USA episode features a different car club or event from across the US, where passionate owner communities gather to share automotive experiences and embark on incredible adventures.

Porsche suspends 911 GT3 deliveries amidst fears of spontaneous combustion

Seeing pictures of Italian supercars burst into flames by the side of the road, as our compatriots at Axis of Oversteer point out, has become something of a usual sight. But a Porsche? Surely those meticulous German engineers have got that taken care of, right?
Not necessarily. Reports coming in from Europe indicate that no fewer than five 911 GT3 coupes have "spontaneously combusted" in the past few weeks, prompting Porsche to launch an investigation. In the meantime, they've reportedly ceased deliveries of the new GT3 while they try to determine what the problem is and work to rectify it.
We wouldn't be surprised to see a recall issued once the problem is resolved, but for now, we'd encourage existing owners to be extra vigilant behind the wheel - or better yet, leave their cars in the garage for the time being. You wouldn't want to drive a 475-horsepower rear-drive sports car through a Polar Vortex, anyway, right?
