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.

2016 Porsche 911 Carrera is all turbo, all the time [w/video]

There's always a lot of fanfare around a new version of the iconic Porsche 911. But for 2016, there's a huge reason to take notice. Porsche is turbocharging the full 911 range, introducing a new, 3.0-liter flat-six that will serve as the base engine in the Carrera and Carrera S. Purists may scoff, but there's proof in the pudding that this is a good move for the 911 range. Base Carreras will produce 370 horsepower and 331 pound-feet of torque, while the Carrera S ups those numbers to 420 and 368, respectively. Porsche says the new 911 Carrera models are much faster than before, reportedly clocking a 7:30 lap time on the infamous Nurburgring. The Carrera tops out at 183 miles per hour, and the S will do 191. A seven-speed manual transmission comes standard, and Porsche's excellent PDK dual-clutch gearbox can be had, as well. The new 911 will arrive Stateside next March, priced from $89,400 for the Carrera and $103,400 for the S. Cabriolet models will sticker for $101,700 to $115,700. The press release below has more information.
