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 close to fix for 911 GT3 engine fires

It looks like 2014 Porsche 911 GT3 drivers might actually get to drive their cars again soon. Reports of fires affecting the track-ready Germans first began about a month ago. Then, a few days later, the automaker confirmed two of the five alleged blazes and said owners shouldn't drive their cars until further notice. Porsche then went so far as to offer to pick up the GT3s and transport them to the nearest dealer until the problem was identified and a fix was found. Finally, there appears to be a repair.
"We know the reason and the problem-solving measures. We're testing them," said Porsche CEO Matthias Müller to Bloomberg. The technical fix will be released to owners shortly.
The recall affects all 785 GT3s that have been sold so far, but there have been no reported injuries caused by the fires. When it first announced the safety campaign, Porsche said: "Internal studies to determine the cause of the engine damage have not been completed yet."

Porsche 911 and Citro"en DS lovechild would look like this

The early Porsche 911 and the Citroën DS were two cars produced in the same era (though the DS launched in 1955, nearly 10 years before the 911), but they were vastly different from each other. The 911 was a uniquely German, pure-bred sports car, while the French-built DS had four doors and focused more on ride quality than sporting intentions. That made it all the more surprising when we came across the 911DS, a creation that binds the rear half of the Citroën to the front of an early, longhood 911.
The folks at Brandpowder are behind the creation, which we surmise was an exercise in design rather than an actual, completed project (some of the images look Photoshopped), but it's compelling nonetheless, with a turbocharged flat-six providing 260 horsepower. We hope someone builds it - though we're sure if that happened the early 911 crowd would cry afoul at one of its increasingly rare and valuable Porsches being grafted onto an old French car.
But as Brandpowder points out lightheartedly, perhaps the creation could transcend popular car culture: "The 911DS represents the effort of two countries, a genuine attempt to join their energy and talent into one thing. We hope Germany and France will be inspired by Brandpowder's story, as a metaphor for a better and greater Europe."
