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 GT4 spotted at the N?rburgring

It was just the other day that we first caught wind of Porsche's plans to build a GT4 version of the Cayman, and now we're already looking at spy shots of the vehicle in question undergoing testing at - where else? - the Nürburgring.
With more aggressive front-end aero, a GT3-style air vent ahead of the front hood, a large wing at the back, and spindly alloys packed with over-sized brakes at each corner, this Cayman is clearly more extreme than even the range-topping GTS. The rear diffuser and central exhaust tips look about the same as those you'd find at the back of the Cayman GTS, though.
What we can't see, of course, is what Porsche has slotted in under the rear glass, how it's upgraded the interior and how much weight it's stripped out of the thing to get it down to fighting weight, but you can bet it'll come with a substantial power bump and a stripped-out interior with racing buckets and little else to open the gap between it and the GTS... and close the gap to the 911 GT3 which it will join as the baby brother in Porsche's performance-focused lineup.

Evo makes the case for the world's best driving road in Majorca

What good is a sports car if you haven't got a great place to drive it? It's a common refrain that we've heard time and time again. But few are as familiar with the problem as they are in the UK, where the number of people, cars on the road and traffic cameras keep growing to conspire against the joy of driving. Leave it to Evo, then, to depart in search of the greatest driving road in the world.
It's a pursuit that's taken the British car mag across Europe, most recently to Romania's Carpathian Mountains where it added the Transalpina Pass to its short list. But its latest journey has taken Evo to the Spanish island of Majorca, where Henry Catchpole found not one, but two spectacular driving roads from behind the wheel of the new Porsche Boxster GTS. We could drone on about the smooth, empty ribbons of twisting tarmac with excellent visibility and panoramic vistas... but you really want to see the video for yourself. Don't miss Evo's previous trip to Romania in the Jaguar F-Type, which we've included below, as well.
