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.

Despite premium carmakers going downmarket, luxury auto sales stick at 10-11%

According to research conducted by global information company IHS Automotive, the leporine birthing of new models by luxury manufacturers over the past six years hasn't increased their market share in the US. Even as car sales reached 15.6 million units, IHS says what's happened instead is that luxury buyers are merely moving from one brand to another, moving from larger luxury vehicles into hot segments like compact luxury crossovers or leaving the market at the same rate as other buyers enter.
Whether broken out by makes or by segment, market share has rollercoastered inside a narrow band from 10.5 to 11.5 percent since "at least" 2008. Closer investigation reveals the shifting boundaries in the aspirational pond, with brands like Mercedes-Benz and Audi gaining territory as Lexus and Lincoln lost it, and Saab and Hummer were buried, dead, under it. One neat note is that Tesla has gone from a share of zip to .12 percent.
The subcompact and compact crossover segments show growth, with those little high-riders jumping from .3 percent to 1.16 percent of overall industry sales. Their rise, though, is concomitant with the decline of four other segments: compact and midsize cars and fullsize cars and SUVs. We think the next few years that will tell if the small-car expansion can overcome the large-car retraction, with a phalanx of smaller offerings like the CLA only recently hitting the market and others like the GLA, Macan and Q1 doing so in the near future.

Porsche Supercup racer dies in crash in Australia

Even with great strides made towards increasing the safety of motor racing, fundamentally it's still a dangerous sport. And now it has claimed another life.
That life belonged to one Sean Edwards, an accomplished GT racing driver. Edwards was killed at Queensland Raceway in Australia, riding shotgun in a Porsche 996 GT3 while acting as instructor. The driver was airlifted to hospital with critical injuries. Sean Edwards was 26.
The son of former F1 driver Guy Edwards (whose car he drove in the filming of Rush), Sean won the European GT3 Championship in a Porsche 911 GT3 Cup and drove a Mercedes-Benz SLS AMG GT3 to repeat victories at the 24 Hours of Dubai as well as this year's Nürburgring 24 Hours. Edwards had been competing in the Porsche Supercup, whose standings he currently leads with just two rounds to go, and could be crowned champion posthumously.
