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 Panamera Turbo S vs Ariel Atom Supercharged in unlikely drag battle

David versus Goliath battles are always an enticing proposition, because they offer the chance to watch scrappy underdogs take on their bigger rivals. Evo has set up just such a battle with its latest drag race between the minimalist Ariel Atom 3.5 Supercharged (Ariel Atom 3 pictured below) and the plush Porsche Panamera Turbo S.
The two cars couldn't be more different. The Atom personifies Lotus founder Colin Chapman's well-known axiom: "Simplify, then add lightness." Most of the car doesn't even have a body; it's just an exposed frame with a 310 horsepower supercharged Honda four-cylinder mounted behind the driver. On the other side, there's the Panamera Turbo S. In the latest version, it packs 570 hp and 553 pound-feet from its 4.8-liter twin-turbo V8 and it features all-wheel drive. Of course, all of that comes with a significant weight penalty.
Off the line, the differences are even more apparent. The Atom doesn't have any of the Porsche's technological wizardry, so launching it challenges the driver to build the revs and let out the clutch just right. The car screams like a banshee as it goes, though. The Porsche is the exact opposite. Its launch control system lets the driver hold down the brake, get on the throttle and accelerate away in just the right way.

Porsche 918 Spyder roars electric through London

The Porsche 918 Spyder can be an object of lust for anyone who appreciates the finer things in the automotive world, but for us greenies with penchant for speed, the car is an icon. This gorgeous, all-wheel-drive plug-in hybrid offers 887 horsepower and 940 pound-feet of torque, can do 0-60 in just 2.5 seconds and is capable of 214 miles per hour. It lapped the Nurburgring in a record 6:57. Still, it is capable of near-silent, relaxed cruising through one of Europe's busiest cities. In a new video from Porsche, chief driving instructor Gordon Robertson takes the 918 to London and does just that. While driving in E-Power mode, he describes some of the things that make the car special, as well as how the technology has developed through the 911 GT3 R Hybrid and the 919 LMP1 car to eventually be passed onto the Panamera S E-Hybrid. If you're interested, you can learn more about the car in our own drive review, here. It's great to see, for the first time, the 918 Spyder driving alongside London's black cabs and double-decker buses. The rubbernecking from pedestrians is noticeable and completely understandable. I'm sure we'd all love to see this car come silently sneaking down our own city streets, but until Porsche makes that happen, you'll just have to enjoy the video below.
