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.

Porsche 918 Spyder pre-production version in all its almost-done glory

Porsche continues the long tease of its upcoming 918 Spyder, with the latest instantiation here at the Pebble Beach Concours, with the car presented in pre-production form to the throngs on the golf course.
Just a few days ago Porsche dropped an image of the car on its official Twitter feed. True to that leak, this 918 looks damn near what we expect the full customer version to be when it is officially debuted in Frankfurt. The neon-green brake calipers are items new to this version of the 918, and seem to be an identical color to those found on the Panamera S E-Hybrid.
When it shows up as a drivable piece, expect the Porsche supercar, with its gasoline-electric drivetrain, to be pretty insane. Horsepower in excess of 800 ponies will be available with a toe-tap, while the price of entry is expected to come within shouting distance of $850,000. A good deal for Porsche to bring the thing to Pebble then, where buyers with that kind of cash are think on the ground (and most likely wearing sherbet-colored trousers).

Porsche drivers escape this horrific VIR crash unscathed

There is no doubting the fact that it takes nerves of steel to be a racecar driver, but the same can also be said for motorsports photographers. Case in point: The American Le Mans Series Oak Tree Grand Prix at the Virginia International Raceway where two Porsche 911 racecars crash hard into the tire barrier, but the dedicated cameraman stays with the shot - diving away only at the last second just as the battered No. 31 car (shown above) comes to rest atop the tire barriers just feet from where he was standing.
The crash occurred when the two Porsches charged hard into a corner. Judging by the video, the white No. 48 car appears to not see the orange No. 31 and the two cars make contact, skidding off track hitting the tire barriers at a high rate of speed. Both drivers walked away from the frightening crash, but the video - posted below - shows just how bad things could have been. Hopefully the close call will serve as a lesson for the woman standing in the track marshal's post who has her back to the racing as the two cars barrel directly toward her.
