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 Panamera's alluring hind quarters teased

It looks like we'll be seeing the new Porsche Panamera sooner rather than later, after the German company released its first teaser video for its redesigned sedan. Sadly, that image you see above is the only clear view of the new car being offered – the video doesn't offer much. In short, the clip below is all about how Porsche has successfully done its own thing over the years. You know, building cars with the engine in the wrong end and such. It's a nice little recap of Porsche history, showing Porsche's first offerings through to the 918 Spyder. But let's talk about that teaser image. We get a good look at the taillights, the traditional Porsche lettering, and the rear window. Based on these few details, it looks like the new Panamera's tail will borrow some inspiration from the updated 911. The lights are a similar shape, and while the sedan will tie the two units together with a lighting element – kind of like a 911 Targa – it looks like there's a similar character line just above the Porsche lettering. But the really weird detail here is the vertical cutline at the Panamera's center, right above the letter "S" in "Porsche." There's absolutely no reason for it to be there, unless Porsche is going to offer something really weird like a split tailgate, which we doubt. We can't see anything like it in our spy photos, but it'd be a relatively easy thing to hide with camo. But why is it there? We can't wait to find out. This content is hosted by a third party.

Jay Leno puts carbon fiber wheels to the test on a Porsche 911 GT3 RS

Jay Leno's Garage usually focuses on looking at cars new and old, speaking to their owners and then Jay taking a drive to see what he thinks. However, Leno throws his usual shtick to the curb this week to do a full product test of the carbon fiber wheels from a company called Carbon Revolution. If you're not interested in hearing about wheels for 18 minutes, don't worry. They get mounted on a Porsche and are tested back-to-back with stock wheels, and Leno takes the 911 for a track test, too.
While carbon-fiber wheels aren't exactly a new idea, Carbon Revolution's goal is to create a lightweight, one-piece product that can be mass produced. The company even claims that it already has a deal with an OEM automaker to offer them on a vehicle in a few years. The key to the technology is that it doesn't need an expensive autoclave to be made.
In the meantime, the company's carbon fiber wheels are available as an aftermarket option for about $15,000 a set, according to the video. They weigh in at about 15.5 pounds each and offer OEM-levels of stiffness, so they could cut some unsprung mass off of a performance car. Watch here as Jay and his mechanic Bernard lap Willow Springs and give their feedback about what they think of this cutting-edge technology.
