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 Macan fails moose test, Stuttgart responds

Different countries have different safety standards, but most of them revolve around a similar set of tests: front impact, side impact, offset impact, rollover... the usual. But Sweden has its own test. It's called the Moose Test (or the Elk Test), and it's unique to Scandinavia: a car has to be able to avoid a theoretical antlered mammal on the road while traveling at 43.5 miles per hour and return to its previous course without flipping over. The Jeep Grand Cherokee ran afoul of the uniquely Nordic maneuver a couple of years ago, but even more surprising is the way the Porsche Macan has reacted.
Under testing by Sweden's Teknikens Värld, Porsche's downsized crossover - specifically the Macan S Diesel, for what it's worth - didn't flip over, but it skidded off course. In real-world conditions, it follows, the vehicle could run off the road or into oncoming traffic. The testers ran the test several times, and even removed excess weight from the vehicle, and each time it reacted the same way.
In response, Porsche has explained that the behavior is the result of its Active Rollover Protection system kicking in. When the system detects that the vehicle could drastically oversteer, flip over or lose its tire, it momentarily applies the brake on the front outside wheel, allowing the vehicle to shed the cornering forces without losing it completely.

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."
