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.

Robb Report chooses Porsche 911 as its Car of the Year

Robb Report has picked the seventh-generation Porsche 911 Carrera S as its 2013 Car of the Year, saying the two-door captivated its judges with "agility, driving dynamics and balance." The German coupe bested 12 others who were also in the running - the impressive list of nominees included the BMW M5, Audi S8, Ferrari FF, Mercedes-Benz SL63 AMG and the Bugatti Veyron 16.4 Grand Sport Vitesse.
Judging involved more than just throwing darts at pictures on the wall, as the publication enlisted a panel of automotive experts to test drive each vehicle for close evaluation. The panelists included 100 members of the Robb Report Club (comprised of top corporate executives and influential readers), Editor-in-Chief Brett Anderson and automotive consultant Robert Ross. Full results of the competition will be revealed in the luxury magazine's March issue, hitting newsstands in about a week.

Porsche announces plan to replace 911 GT3 engines

About a month back, we reported that Porsche was suspending delivery of its 911 GT3 due to reported incidents of the engine bursting into flames. A few days later, Porsche told owners of the new track-ready models not to drive their cars and had their local dealers pick up the cars in question. Just a couple of days ago, we reported that Porsche was working on a fix, and now we have the official details.
Following an internal investigation prompted by two such incidents, Porsche has confirmed that is has identified the problem as resulting "from a loosened screw joint on the connecting rod." The loose connecting rod, Porsche found, damaged the crankcase, which in turn resulted in oil leaking and then - in at least two cases - igniting.
Our source is unaware of Porsche being contacted by GT3 owners concerned about the impact of a replacement engine on their car's collectibility or resale value.
