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.

Video proof the Porsche 912 deserves a second look

The Porsche 912 suffered from a bad reputation for years as a lesser Porsche among the brand's ardent fans. Some people just didn't see the appeal of a coupe that shared the 911's lines but used a four-cylinder engine. The tide has started to turn recently as ballooning air-cooled 911 prices present these cars as an interesting alternative. The latest clip from Petrolicious also makes a great argument for the 912 by showing a Bahama Yellow example cruising along French roads. Like many of us, Antoine Gaslais had a tight budget and searched for years for his dream car. Things were more of a nightmare when he found his 1967 912, though. The coupe initially didn't run and then broke down once he thought it was fixed. A buddy eventually helped him get the Porsche back on the road. Gaslais knows his 912 isn't concours perfect, but that's not the point for him. Gaslais just likes to be able to cruise. Take a ride with him through some French hamlets in the latest from Petrolicious.

Porsche sees error of ways, next 911 GT3 to offer manual transmission

Consider this Porsche's mea culpa. After creating an uproar over selling a new 911 GT3 without a manual transmission, the automaker introduced the limited-edition, manual-equipped 911 R in Geneva. That car is just a stopgap, though. It's meant to hold 911 drivers over until the next GT3 arrives with the same six-speed manual transmission. Yes, the next-gen GT3 will get an old-fashioned six-speed manual, according to a new report from Autocar (but the GT3 RS will still be PDK-only). In fact, the same report claims Porsche will make sure that the 911 GT3 remains the car for the brand's most ardent purists. While the rest of the Porsche range moves to turbocharged engines, the GT3 will stick to its naturally aspirated guns. That comes direct from the big boss behind the GT3, Andreas Preuninger, who told the magazine this would be the case "for the foreseeable future." According to Preuninger, the only member of Porsche's GT line that will go turbocharged is the one that's been that way all along – the GT2 and GT2 RS, which we'll see next year. And yes, Preuninger's statement about limited turbocharging applies to the Cayman GT4, too, even though the model that high-performer is based on has moved to a line of turbocharged engines. When the next GT4 arrives, it'll be with a flat-six in the middle. Related Video:
