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 911 GT3 RS spec sheet leaked, promises 500 hp

Axis of Oversteer has three pages of what's purported to be the spec sheet for the Porsche 911 GT3 RS, and it's got a few bolded items noting key differences with the already spectacular 911 GT3. Prime among them is its output, pegged at exactly 500 horsepower and 339 pound-feet of torque, which looks at first blush to be a minor bump: just 25 hp and 14 lb-ft over the GT3, and the redline drops 200 rpm to 8,800 rpm. If the document is accurate, though, there will be a hefty dose of weight loss to make the most of it. The bodyshell and doors are aluminum, carbon fiber reinforced plastic is used for those vented front fenders (the vanes are plastic), the front trunklid, the rear engine cover, and the rear wing, while the roof is made of magnesium and the side windows are polycarbonate. The bucket seats, door entry guards, and other interior trim pieces are also fashioned from CFRP, and it gets lightweight door panels with pull-loops. Elsewhere around the coupe, the body grows wider by 50 millimeters in front and 30 mm in back over a track that's 36 mm wider. There's a pit-lane speed limiter for track days, tinted taillights, an optional Clubsport package with a six-point seatbelt, and GT3 RS logos everywhere. It's looking more and more like this car was developed to define the word "epic."

2016 Porsche 911 Carrera is all turbo, all the time [w/video]

There's always a lot of fanfare around a new version of the iconic Porsche 911. But for 2016, there's a huge reason to take notice. Porsche is turbocharging the full 911 range, introducing a new, 3.0-liter flat-six that will serve as the base engine in the Carrera and Carrera S. Purists may scoff, but there's proof in the pudding that this is a good move for the 911 range. Base Carreras will produce 370 horsepower and 331 pound-feet of torque, while the Carrera S ups those numbers to 420 and 368, respectively. Porsche says the new 911 Carrera models are much faster than before, reportedly clocking a 7:30 lap time on the infamous Nurburgring. The Carrera tops out at 183 miles per hour, and the S will do 191. A seven-speed manual transmission comes standard, and Porsche's excellent PDK dual-clutch gearbox can be had, as well. The new 911 will arrive Stateside next March, priced from $89,400 for the Carrera and $103,400 for the S. Cabriolet models will sticker for $101,700 to $115,700. The press release below has more information. The sports car legend enhanced: the new Porsche 911 Carrera New turbocharged engines, an advanced chassis, and new Porsche Communication Management Atlanta, Georgia. Celebrating its debut at the Frankfurt International Auto Show, the new 911 Carrera is taking performance and everyday usability to new heights. Innovative flat-six engines derived from four decades of turbocharging used in racing and on road cars not only make this the fastest 911 Carrera ever, but also provide abundant torque for superior passing power. An advanced chassis offering an even more sophisticated combination of ride comfort and performance characterizes the handling of the new 911. For the first time, rear-axle steering is available as an option for the Carrera S, significantly enhancing its already superb agility. These improvements reduce the lap time on the North Loop of the Nurburgring to just 7 minutes and 30 seconds, making it 10 seconds faster than the previous Carrera S. Many exterior features of the 911 Carrera have been visually refined from new headlights with four-point daytime running lights to integrated door handle recesses, a redesigned rear deck lid with vertical louvers, and new rear lights – including the characteristic four-point brake lights. The new standard Porsche Communication Management system with a multi-touch display offers an expanded range of functions and simplified usability.
