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 Cayman gets a new face

We've already seen photos of the facelifted Porsche Boxster out testing, but we're now seeing these same changes making their way onto the hardtop Cayman coupe. Cosmetically, the next round of Porsche's smallest sports cars isn't vastly different, with redesigned headlamps, LED running lights (like its big brother, the 911), and new taillamps that actually aren't visible on the prototype seen here.
The big news for the updated Boxster/Cayman range is the long-rumored four-cylinder engine. Recent reports suggest we could see four-pots with displacements of 1.6, 2.0, or 2.5 liters, and with output ratings as high as 360 horsepower. Of course, these new four-cylinder mills would be both turbocharged and direct-injected.
It's unclear whether or not the six-cylinder engine range will also be updated when this new Cayman comes to market. In any case, we expect to see it bow in the relatively near future. Stay tuned.

Porsche reveals new Panamera Turbo S ahead of Tokyo debut

For many buyers in the market for a luxury sports sedan, style is as important as performance. But while the Porsche Panamera undoubtedly delivers in the latter category, it falls somewhat short in the former. Porsche went to some lengths (if not quite far enough for some tastes) to improve its four-door model's visual appeal with the facelift revealed earlier this year, but now it's time to up the performance game with the new Panamera Turbo S.
Set to be revealed at the Tokyo Motor Show in just a few weeks from now, the new top-tier Panamera benefits from several key upgrades over the existing Turbo and the pre-facelift Turbo S. For one, its 4.8-liter twin-turbo V8 now produces 570 horsepower (up from 520 in the new Turbo and 550 in the old Turbo S and the latest Cayenne Turbo S) and 553 pound-feet of torque (up from the current Turbo's 516 but the same as the previous model). Despite the power boost, however, Porsche is quoting the same 3.6-second 0-60 time for the new Panamera Turbo S as it did for the previous one - but then that hardly required improvement in the first place. Top speed, however, is up to 192 miles per Autobahn-blurring hour, two mph faster than the previous model.
Other features include carbon-ceramic brakes (hopefully with more durable bolts than sister companies Lamborghini and Bentley have been using) packed inside the wheels from the 911 Turbo and an exclusive shade of greige called Palladium. And for the first time, customers will be able to order this top-spec model in long-wheelbase Executive trim. But don't expect it to come cheap: MSRP (before delivery and options) is quoted at $180,300 for the standard wheelbase and $200,500 for the stretched model. That's two and a half times the price of a base Panamera, and makes the new Panamera Turbo S Executive both the most expensive and most powerful Porsche your can buy this side of a 918 Spyder. Haven't passed out yet? There's more to digest in the press release, so head on down below to take it all in.
