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.

2014 Porsche Panamera 4S Executive

If the idea of a Porsche sedan (or, long hatchback) is still off-putting to you, then you might want to look away now. For 2014, the polarizing Panamera has received a midcycle refresh bringing slightly different styling, as well as adding two new models to the lineup, the S E-Hybrid and the stretched-wheelbase Executive. Having focused most of my recent trip to Germany on a First Drive of the intriguing plug-in Panamera, I also got to spend some time with the roomier Executive model.
Offered in both 4S and Turbo guise, the Panamera Executive has been stretched by almost six inches for the sole purpose of improving rear passenger space. Although it's hard to imagine anyone would willingly buy a Porsche and opt to sit in the back seat, I'd have to say that if I'm going to be chauffeured around in a car, why not make it a Porsche? For the most part, though, I'm guessing that many Panamera Executive sedans will be owned by people who want to one-up their buddy driving a stretched BMW 7 Series or Mercedes-Benz S-Class.

Porsche announces four flavors of updated Cayenne [w/video]

The new Macan may be getting all the attention lately, but Porsche hasn't forgotten about its larger crossover - the one that put it on the map in 2002 and on the road to profitability, with over half a million sold so far. So to keep the Cayenne at the top of its game, Porsche has announced several key upgrades for the 2015 model.
For starters, Porsche has updated the Cayenne's appearance with new front- and rear-end styling. The front bumper, fenders and hood are entirely new, with air fins flanking the nose to direct air into the intercoolers (each model now being artificially aspirated), and new bi-xenon headlamps and daytime running LEDs on every model but the Turbo, which goes all-LED. Around back there's also new taillights, tailgate handle, lower rear fascia and exhaust pipes. Meanwhile the interior has been upgraded with a 918-derived sport steering wheel and reformed rear seats with available ventilation.
The bigger news is under the engine bay, where Porsche is offering four choices. The base model is gone as the range starts with the Cayenne Diesel, followed by the Cayenne S, the new Cayenne S E-Hybrid and the top-of-the-line Cayenne Turbo. The Diesel model carries over the same 3.0-liter turbo diesel with 240 horsepower. The Cayenne S however packs a 3.6-liter twin-turbo V6 that's similar to the one found in the Macan Turbo and packs the same 406 lb-ft of torque but more power at 420 hp, 20 more than either its little brother or the model it replaces to reach 62 mph in 5.2 seconds.
