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.

Next-gen Porsche Panamera loses its buttons

We have our first interior images of the next-generation Porsche Panamera. Caught undergoing testing in what looks like the area around Ann Arbor, MI, Porsche's second-gen sedan ditches the multitude of buttons found on the center stack of today's cars in favor of touch-capacitive controls. The new look works on the interior. It's clean and stylish, and the overall layout is clearly inspired by the Panamera Sport Turismo concept. We're particularly fond of of one of the features absent on the concept car – the wide, high-resolution infotainment screen. Judging by the lack of a dedicated controller on the center stack and the screen's proximity to where the driver's right hand would be, this is almost certainly a touchscreen. According to our spies, the software on that screen will be shared with Bentley, as will the Panamera's underlying platform. The new steering wheel, meanwhile, looks like it's been plucked straight from the 918 Spyder. There's a very visible protrusion at the four-spoke wheel's four o'clock position, and the button layout on the spokes looks identical to the hybrid hypercar. On the 918, this controller manages the hybrid systems, but as our spies claim this is the gas-powered Turbo S model, we aren't really sure what role it will play as we can clearly see drive mode controls on the center console. Speaking of the Sport Turismo, this prototype backs up the argument that the next Panamera will adopt the cleaner look of the 2012 Paris Motor Show concept. Even with the camouflage, the C-pillar and rear quarter window, squared-off trunk aperture, and the four LED accents in the headlights are clearly inspired by the Sport Turismo. However, the concept's most dramatic feature – its strong hatchback profile – doesn't seem to have made the transition into this prototype. We'd expect to see the new Panamera in either Geneva or Paris. The Swiss show is the unlikely choice, though, considering it's just over a month away and Porsche already has another big debut planned. So expect the new Panamera in the City of Light. Sales should begin some time in 2017.

A fix and buyback program for Audi V6 diesels may be on the way

While Volkswagen reached a settlement to buy back 2.0-liter diesel inline-fours with emissions defeat devices, the roughly 80,000 cars with 3.0-liter diesel V6s built by Audi have yet to be addressed. But a new report from Bloomberg indicates that a solution is near. The publication says that sources familiar with the situation say the company has a fix ready for the majority of the cars, and that the EPA and California Air Resources Board are ready to approve it. According to Bloomberg, this fix would involve a software update and would work for about 60,000 of the Audi A8, Q5, Q7, Porsche Cayenne, and VW Touareg models with the engine. The rest of the vehicles won't be fixable without major modification, so those would have to be purchased back from the owners. Bloomberg does point out that approval from the EPA and CARB are only one piece of the puzzle. The publication said that this deal has yet to be approved by owners of the cars and the Federal Trade Commission, both of which may demand that VW offer a buyback to all owners, even those whose cars can be fixed. The good news for owners of VW products with this engine, is that they should have some closure pretty soon. And owners that still like their diesel V6 can take solace that they might actually be able to get them fixed, as opposed to owners of the 2.0-liter diesels. VW offered buybacks to owners of all 475,000 cars with the turbo four-cylinders, or a fix when it's available. However, there have been no signs of an approved fix.
