Popular Science magazine's Best Of What's New 2012 all ate up with cars

Popular Science has named the winners in its Best of What's New awards, the victors coming in the categories of aerospace, automotive, engineering, entertainment, gadgets, green, hardware, health, home, recreation, security and software. The automotive category did not go wanting for lauded advancements:
Tesla Model S: the Grand Award winner for being "the standard by which all future electric vehicles will be measured."
BMW 328i: it's 2.0-liter turbocharged four-cylinder gets called out for being more powerful and frugal than the six-cylinder it replaces.

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.

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.
