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 revealed in patent photos

Porsche has been taking its time developing the most hardcore 911 models for the latest 991 chassis. While the GT3 has been on the market for a little while, it suffered from some teething issues. The 911 GT3 RS is certainly on the radar since being spotted testing, but it's always better to get a look at a new car without all of the camo to hide the coolest parts. Thankfully, Car in the UK has some patent photos of the RS ahead of its debut, and they show off one mean-looking 911.
The first thing that you notice about the RS is that Porsche clearly isn't afraid to rework the latest 911's shape for its track-focused version. Each piece is slightly resculpted to squeeze the most out of it. Up front, the air dam has the same shape to the earlier photos. They also both highlight the upcoming model's tiny air inlet at the tip of the hood, the massive intakes in the rear fenders and general design of the rear wing with a ducktail underneath. The bubbled roof is much clearer here, where it was disguised in spy shots. You can also spot the slashing fender gills behind the front wheels that are a completely new feature.
The GT3 RS is the ultimate naturally aspirated 911 for the street, but according to Car, Porsche aims to take that even farther with the latest model. If these are the looks, then it's working. Unfortunately, the new version's powerplant remains a mystery. Though, given all the changes to the bodywork, the engine is almost surely getting tweaked over the 475-horsepower GT3. The RS is rumored to hit the road and be screaming down the track in 2015.

Porsche (finally) unleashes full, official details on 918 Spyder

Porsche has finally let released all of the details on the 918 Spyder, the German brand's challenger to the McLaren P1 and Ferrari LaFerrari, after months of leading our poor, performance-loving hearts on. The covers were lifted at the Volkswagen Group night, an enormous precursor to the Frankfurt Motor Show, and include a massive, 11,000-word press release that's attached at the bottom of this page.
The 918 Spyder features a mid-mounted, dry-sump-lubricated, 4.6-liter V8 engine that generates 608 horsepower when left to its own devices. Combined with a trio of electric motors, which produce 286 hp, the total system horsepower for the 918 Spyder rests at 887 ponies. That's less than the McLaren P1 (903 hp) and the LaFerrari (949 hp), but the Porsche is also likely to be a bit cheaper, starting at $845,000, while the McLaren will be in the seven-figure range for certain, and it will more than likely be joined by the LaFezza.
The 918 Spyder counters with a 2.8-second jog to 62, a 7.7-second run to 124 and it will hit 186 in 22 seconds.
