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.

Weekly Recap: Mercedes continues the pseudo-coupe craze with AMG-tuned CUV

But as BMW's X6 has demonstrated, sport sells in in the crossover segment, and Mercedes is giving the people what they want. BMW proved there is a market for crossover utility vehicles designed to look like coupes – as much as a vehicle with four doors and noticeable ground clearance can look like a coupe, anyway. Now comes the reply from Mercedes-Benz: the GLE Coupe. The rakish crossover is a harbinger of things to come from Mercedes, as it begins the company's transition to a new nomenclature and marks the debut of the AMG Sport line. It also continues the recent coupe craze. Designers from many automakers, like Nissan and Volkswagen, have increasingly turned to swoopy, dramatic styling to make utility vehicles and sedans seem more desirable. By revealing the GLE 450 AMG Sport model first, Mercedes is clearly hoping to cast the GLE Coupe as a sportier, lifestyle-oriented alternative in its lineup of beefy crossovers and SUVs. Mercedes used the word "sport," or a variation of it, 53 times in its press release, so uh yeah, it's sporty. It's not an empty promise: Benz means business with the AMG Sport line. This GLE Coupe gets a 3.0-liter biturbo V6 rated at 362 horsepower and 384 pound-feet of torque paired with Mercedes' new nine-speed automatic transmission, and it runs with 4Matic all-wheel drive. Specs on the other GLE Coupe models were not disclosed. But as BMW's X6 has demonstrated, sport sells in in the crossover segment, and Mercedes is giving the people what they want. After all, more than 260,000 people have bought X6s since 2008, and Mercedes wants a piece of that. From certain angles, the GLE Coupe even looks vaguely like an X6. "This is really a vehicle that is all about status," said Dave Sullivan, product analysis manager for research firm AutoPacific. "You can buy a SUV that doesn't have the inherent qualities of a SUV, such as cargo hauling. People will likely be drawn to the looks. Coupes are all the rage." BMW, however, isn't running from the fight, and the updated 2015 X6 is arriving in showrooms this month. It also added a smaller sibling, the X4, to its coupe-crossover stable in July. The GLE Coupe arrives next year, though Mercedes hasn't specified exactly when it will hit showrooms from the factory in Alabama, or specified details on the rest of the non-AMG Sport models. In 2008, it was surprising the X6 was a hit. In 2015, it will be even more surprising if the GLE Coupe isn't.

Porsche 911 GT3 dukes it out with MP4-12C on track and GT-R on spectacular roads

The Porsche 911 GT3 has always been a favorite among auto journalists and car enthusiasts alike, but with the introduction of the new 991-generation GT3, which is the first GT3 with electric power steering and no manual gearbox option, how does it stack up to the competition from McLaren and Nissan?
Evo's Jethro Bovingdon attempts to answer that question by pitting the rear-engine Porsche against the mid-engine McLaren MP4-12C on a racetrack and the front-engine, all-wheel-drive Nissan GT-R on some amazing, twisty European back roads. We won't give away the victor of either comparison, but we will say that, in Evo's test, the McLaren's 141-horsepower advantage doesn't give it as much of an edge over the Porsche on a racetrack as one might think, and the lack of a manual gearbox and the inclusion of electric power steering on the GT3 isn't detrimental to enjoying the car on a back road.
Watch the video below to find out which car Bovingdon prefers on road and track - we think you'll be happy to see him drift around turns every chance he gets.
