Porsche 918 Spyder officially priced from $845K, Weissach package $84K more

Porsche has released official pricing for its entire lineup of 2013 models, which just happens to include the upcoming 918 Spyder hybrid supercar. The 795-horsepower advanced-technology-lab-on-wheels is now officially confirmed to have a starting price of $845,000 in the US, which is the exact amount we were told earlier when we had the opportunity to ride shotgun in some 918 Spyder pre-production test vehicles.
What we didn't know at the time was the cost of the Weissach trim package, which is a high-performance upgrade to the standard vehicle that includes the deletion of some interior amenities and addition of lighter-weight carbon fiber appointments, magnesium wheels, flame-resistant upholstery, racing belts and aerodynamic aids - it's meant for track-going folk who intend to use their 918 Spyders as God, country and manufacturer intended.
All told, the Weissach package should drop the 918 Spyder's curb weight by some 80 pounds, while also lightening your wallet of an additional $84,000 - the car's MSRP with the Weissach package is $929,000. These prices don't, however, include destination charges, which, for something like the very limited edition 918 Spyder (only 918 will be made), could very well cost considerably more than your average Porsche.

Corvette gets slidey with Britain's best performance cars

Autocar wants to find Britain's best driver's car, and it's challenging a murderers' row of some of the world's best performance vehicles to find out, including the latest Chevrolet Corvette Stingray. All of them were therefore assembled at the Castle Combe Circuit to find a winner.
If it wants to take the crown from this pack of mostly European competitors, the 'Vette has to beat some steep competition. Its challengers include monsters like the Ferrari 458 Speciale, Ariel Atom 3.5R and Jaguar F-Type Coupe. As a further hurdle for the winner to clear, Autocar also has last year's champ among the fighters - the Porsche 911 GT3.
Even if you're not at all interested in the C7, there's still something here for practically any fan of fast cars. The competitors include relative oddities among the pack like the Renault Mégane RS Trophy and Alfa Romeo 4C. Plus, Autocar has some well-positioned microphones that let you hear the Atom wailing like a banshee and the roar of the 458 Speciale. Check out the video to see which one of these all-stars takes home the award this year.

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.
