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.

Weekly Recap: Porsche embarks on Mission E

Porsche's board of directors approved the company's first all-electric car Friday, signing off on production of the eye-catching Mission E concept that debuted in September at the Frankfurt Motor Show. It's set for launch by the end of the decade. The Frankfurt concept uses lithium-ion batteries to power two synchronous motors that create more than 600 horsepower and provide a range of 311 miles on the European cycle. It's capable of hitting 62 miles per hour in 3.5 seconds and can run the Nurburgring Nordschleife in less than eight minutes. In a statement, Porsche board chairman Oliver Blume called the Mission E the "beginning a new chapter in the history of the sports car." Porsche is backing that up with a roughly $1.1-billion investment that will create more than 1,000 jobs at its facilities in Zuffenhausen, Germany. The company will spend more than $760 million at its main site there to build a paint shop and a new assembly plant. It will also expand an engine factory to make electric motors. Porsche's renewed electric ambitions come as it grapples with fallout from parent company Volkswagen's diesel-emissions scandal. Porsche uses a VW diesel engine in the Cayenne SUV, which it stopped selling in November until a fix is found. Still, Mission E's scheduled landing could be as much as four years away – when Porsche and VW hope their diesel woes will be long over. The electric strategy is clearly a long play to provide its enthusiast owners with an efficient form of sport and luxury as fuel economy and emissions regulations tighten around the world. And if you still can't wrap your head around electric Porsches, the company also just announced plans to make the 911 Turbo and Turbo S even more powerful. Electric propulsion is part of Porsche's future, but for now at least, it isn't everything. OTHER NEWS VW sales crash 25 percent in November Finally, the other shoe dropped. Volkswagen sales plummeted 25 percent in November as fallout from the company's diesel-emissions scandal finally showed up on the sales charts. VW had managed to tread water with flat sales through September (the scandal broke more than halfway through the month) and October. The company stopped selling its 2.0-liter I4 and 3.0-liter V6 diesels as it works to make the engines complaint with emissions rules. VW admitted to rigging its diesel-powered cars so they could pass emissions tests in the United States and around the world.

Best Convertibles for 2022

The past decade has not been kind to the drop-top enthusiast. No matter which dealer you walk into, convertible models have been biting the dust left and right. Nissan Z? Audi TT? Buick Cascada? Volkswagen Eos? All gone. Remember the humble Chrysler Sebring/200? Well, you do now. Fortunately, though, the news isn't all bad. There are still plenty of options out there for those who absolutely must have a convertible. Whether you need something to haul behind your retirement cruiser, a performance car that can go toe-to-toe with the best in the world or just something that allows you to sling the roof back after a long day of on-location business meetings before catching the flight back to your everyday hustle and bustle, there's at least one cabriolet out there to suit your needs. Here are our picks and starting prices for the top convertibles in several categories for 2022.  For the frugal open-top lover: 2022 Mini Convertible ($34,650) Let's face it; gas ain't cheap. But open-top motoring doesn't need to be a wallet killer. The Mini is cheap (at least by 2022 standards) and an absolute joy to drive, so there's really no downside here ... except for the roof. Get it?    For the hardtop lover: 2022 Mazda MX-5 RF ($37,260) / 2022 Chevrolet Corvette Convertible ($69,695) The number of hardtop convertibles has seriously dwindled due to weight concerns and the fact that fabric roofs have gotten so quiet, but there are still some options for those who prefer a more coupe-like look with the roof up. Our picks here are the delightfully Targa-like MX-5 Miata RF and literally any Corvette Stingray — even the hardtop has a removable roof!    For long road trips: 2022 Ford Mustang Convertible ($34,100) The first image that comes to mind for many who are told to visualize an American convertible is the classic Ford Mustang. It's not the only drop-top pony car out there, but thanks to the Camaro's tiny trunk, it's much harder to see the USA in a Chevrolet when a drop-top enters the equation. The Mustang has much more cargo space and a much larger opening, which is likely the difference between keeping your bags under lock and key or leaving them exposed in the back seat.    For towing behind an RV: 2022 Jeep Wrangler ($31,590) While many small runabouts make sense for towing behind a motor home (or nestled up inside a fancier one), the Wrangler has a serious advantage when it comes to RVing: it can easily be flat-towed.
