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's latest Driver's Selection keeps enthusiasts happy at home

Porsche fans - and there are certainly plenty of them out there, even in here on the Autoblog editorial staff - can be pretty emphatic about their enthusiasm, insisting that the 911 is the very definition of the sportscar. And for some, merely admiring one from afar or even leaving theirs parked outside isn't enough. For just such enthusiats, Porsche Design has expanded its Driver's Selection with some tantalizing additions for the home and office.
First up is a desk chair made from the bucket seat in a 911 Carrera, which we have to admit we'd rather be sitting in right now over this blasted, rather unexciting ergonomic office chair. It's covered in black leather (the same you'd find inside an actual 911) embossed with the Porsche emblem and features electronic backrest adjustment.
There's also a wall shelf made from the carbon-fiber rear spoiler a 911 GT3 Cup racecar that can support up to 264 pounds of downforce in the form of books, trinkets and whathaveyou. And there's a limited-edition resin model of the 918 Spyder in 1:8 scale. The items haven't hit the Porsche shop just yet, so we don't have pricing information, but if they tickle your fancy, the online store has plenty more to offer.

NHTSA closes probe into 2011 Porsche 911 coolant leaks

The National Highway Traffic Safety Administration has announced that it will end its investigation into rapid coolant loss in 24,635 Porsche 911s built between 2001 and 2011. The models affected included the standard 911, GT2, GT3 and Turbo, as well as their variants (GT2 RS, GT3 RS and Turbo S).
NHTSA was investigating for "rapid coolant loss caused by coolant pipe-fitting failure, allegedly resulting in vehicle disablement and/or loss of vehicle control due to reduced traction for the affected vehicle or following traffic," according to the regulators website. "Most of the leak complaints did not appear to involve complete separation of the fittings and many were detected when the vehicle was parked," said NHTSA's statement.
There were 63 complaints and 336 warranty claims, although the investigation was initiated after ten complaints from customers. There have been no reports of crashes or injuries attributed to rapid coolant loss.
