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.

2015 Porsche Panamera S E-Hybrid

When the Porsche Panamera joined the hybrid poker game with the S Hybrid, it started with a seat at the penny-ante table: engineers inserted a 47-horsepower electric motor between the gas engine and eight-speed automatic, powered by a 1.7-kWh nickel-metal hydride battery. It was tiny stakes, the kind of non-risk taken when you're trying to figure out both how to play the game and how you want to play the game. After two years of experimenting, the 2015 Panamera S E-Hybrid makes a bigger bet – the kind that requires paper bills and the maxim, "If you can't fold it, hold it." Porsche's plug-in hybrid gets every adjective we expect of a successor from Stuttgart: more complex, more efficient, more powerful and faster. Driving Notes The electric motor leaps from 47 hp to 95 hp thanks to more windings on the stator coils and new power electronics. The battery goes from a 1.7-kWh nickel-metal hydride unit to 9.4-kWh lithium-ion setup; it's the same physical size as before, still mounted under the cargo deck. Internal combustion still comes from the Audi-sourced, 333-hp, supercharged V6, but total system power goes from 380 hp and 428 pound-feet of torque in the S Hybrid to 416 hp and 435 lb-ft in the S E-Hybrid. The previous system could run a mile on electricity, this one is estimated to last more than 20 miles on e-power on the European cycle. The 0-60 dash takes 5.2 seconds, down from 5.7 seconds; top speed in electric-only mode is 84 mph – up from 50 mph. It takes 2.5 hours at a 240-volt outlet to fully recharge the battery; the Porsche Universal Charger comes equipped with a cable for that and a standard 120-volt socket. Only Panamera obsessives will notice the sheetmetal changes for 2015, but there are sharper lines on the front and rear fascias, faint revisions made to the light clusters, wider glass – over the same-sized opening – on the rear tailgate, and a wider rear spoiler. Outsiders will know the S E-Hybrid because of Acid Green highlights on the fender and tailgate logos, as well as the Acid Green brake calipers. Inside, the central tach remains, but the analog speedometer was evicted to make space for the battery power meter, and Acid Green needles dance across all the gauges. The navigation screen shows your electric driving range and the Porsche Car Connect service provides the expected, smartphone-controlled e-mobility features.

Former Top Gear crew starts filming for Amazon show

We might have only a hint at the name and no exact date for a premiere, but fans can celebrate that Jeremy Clarkson, Richard Hammond, and James May are filming once again. Plus, it looks like every cent of Amazon's reportedly lavish budget is being put on the screen. A photo tweeted by Clarkson shows the three hosts standing proudly in front of a Porsche 918 Spyder, Ferrari LaFerrari, and McLaren P1 at a racetrack. Clarkson jokes that the show has just a "skeleton crew" but behind him stand several dozen people, a sophisticated-looking camera rig, and two big trucks. This definitely looks worth the anticipation of the premiere on Amazon Prime next fall. Hammond tweeted the same picture and wrote: "The band is back together and it feels brilliant."

Intriguingly, it appears that fellow British auto journalist Chris Harris is currently filming at the same track. He tweeted a photo to Clarkson of the McLaren doing a very smoky slide, while being followed by the other two hypercars. The Porsches in both photos wear the same red-and-white number 3 livery and have the same license plate number. In a later message, Harris was also clear that he wasn't filming there in connection with the trio's Amazon show. This content is hosted by a third party.
