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.

See what the Chevy C7 ZR1 may be benchmarked against

One of the greatest things every Corvette has had going for it, and also one of the most re-used arguments against it, is its price-to-performance equation - long before the Nissan GT-R became the de facto Porsche 911 comparator the Corvette spent decades as Exhibit A. Depending on which side of the argument you stressed, supporters crowed about how much performance you got for how (comparatively) little, detractors carped on how little you got everywhere else in the bargain.
It appears Chevrolet is working as hard as ever to render the argument meaningless. Spy shooters at KGP captured a convocation of European birds of prey leaving the General Motors test center, and aimed at benchmarking the C7 Corvette ZR1. The road train comprised of two C7 Corvette Stingrays, a 2013 Corvette ZR1, McLaren MP4-12C, Ferrari 458 Italia, Audi R8 V10 Spyder and Porsche 911 Carrera S and it was last seen heading down the same kinked-up back roads used to hone the Corvette Stingray.
The C7-series ZR1 and its possible 700 horsepower are still a ways off. If it really is being positioned to compete with the celestial exotica in the testing group, could it be the first Corvette to regularly be the first answer to the question "Cost no object, which would would you rather have?"

Porsche Cayenne GTS, base models revealed ahead of LA

Porsche unveiled a slew of refreshed Cayennes just a few months ago, but the base model (right) and high-performance GTS trim (above) were conspicuously absent from that list. There's no more reason to wonder about them, though, because the German brand plans to unveil both at the upcoming Los Angeles Auto Show on November 19.
Sitting below the Turbo in the lineup, the latest GTS still offers plenty of performance. It drops the previous version's naturally aspirated V8 in favor of a tuned version of the twin-turbo 3.6-liter V6 from the Cayenne S for some added oomph. The tweaks bring power up to 440 horsepower and 445 pound-feet of torque, which is enough to rocket the model to 62 miles per hour in an estimated 5.2 seconds. The bump also equates to 20 hp and 39 lb-ft more than the current S and more importantly 20 hp and 62 lb-ft more than the previous GTS, according to Porsche.
In addition to the extra muscle, Porsche also decks the GTS out with some added features. It comes with a standard sport exhaust and Porsche Active Suspension Management system with an air suspension lets the chassis sit about three-quarters of an inch lower (20 millimeters). To bring things to a halt, the high-performance models also takes its brakes from the Turbo model.
