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.

Leno steals Porsche 918 from The Quail for latest Garage episode

Just because he's a famous celebrity doesn't mean Jay Leno got to take it easy at the Pebble Beach Concours d'Elegance earlier this month. Having already spent some time with the gorgeous Cadillac Elmiraj Concept and Ed Welburn for a recent episode of Jay Leno's Garage, the late night talk show host also got to put a few miles on a prototype version of the Porsche 918 Spyder.
Like a usual episode of JLG, Leno first goes over the details of the car with Frank Walliser, head of the 918 Spyder's development, before taking it out for spin. Check out the full episode, which is posted below, to hear what Walliser has to say about the car. More importantly, though, crank up your computer's volume and let the car's high-revving engine and amazing exhaust note do plenty of talking for itself.

Porsche patent sketches show removable headrest wind deflector

While driving around in a convertible might seem glamorous, ask anyone with long hair and they'll likely tell you how it really is: the wind buffets, your hair goes everywhere and it's anything but glamorous. That's why you see so many convertibles driving with their tops up, their windows up or wind deflectors in place. But Porsche is apparently preparing to kick it up to the next level.
These patent drawings have leaked out, demonstrating what appears to be some new kind of wind-deflecting device being developed by Porsche. The mechanism is apparently fitted to the headrest itself and designed to keep the wind buffeting specifically around the head down to a minimum while allowing the car's occupants to enjoy the top-down driving experience.
No word on when it might hit the market, but we won't be surprised to see this kind of device appear on a future version of the Boxster or 911 Cabriolet. But nowhere else: despite the apparent leak, the patent drawings suggest that Porsche will be keeping this technology proprietary. Whether sister brands like Volkswagen, Bentley or Lamborghini will get their hands on it remains to be seen.
