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.

A relationship between a Minnesota ethanol producer and retailers means cheap E85 for customers. The DENCO II ethanol plant began blending its own E85 fuel in 2011, and now sells directly to 45 gas stations. DENCO II sets the pricing for the fuel, and has been running a promotion for certain retailers to sell E85 for about a dollar cheaper than E10 gasoline. That promotion includes a Cenex station in Alexandria, MN selling E85 for just 85 cents per gallon. The result has been success for both the producer and gas stations, with customers having more cash to spend on retail goods when they go inside to warm up. Read more at Ethanol Producer Magazine.

Tesla said the trailer's white paint set against the bright sky were the reason the driver and the Autopilot didn't stop the car. Tesla also called this accident a "tragic loss," and pointed out that it's the first death involving Autopilot in more than 130 million miles. The National Highway Traffic Safety Administration [00:00:30] has opened a preliminary evaluation of Tesla's Autopilot.

With a clear styling link to the Porsche 911, we think this is the best looking Panamera yet. The new Panamera's body is made mostly from aluminum, minus some high-strength steel and optional large panoramic roof overhead. A completely new range of engines powers the second-gen Panamera, starting [00:01:00] with a twin-turbo 2.9-liter V-6 that puts out 440 horsepower and 405 pound-feet of torque. The Panamera Turbo boasts a 4.0-liter, twin-turbo V8 with 550 hp and 567 lb-ft. Both the 4S and the Turbo come with standard all-wheel drive and an eight-speed PDK dual-clutch automatic transmission. Porsche is claiming that this Panamera set the Nurburgring record for a production sedan finishing just 14 seconds quicker than the outgoing model. We expect to see the 2017 [00:01:30] Porsche Panamera hit deals in January of 2017. Find more details at Autoblog.com. I'm Chris McGraw.
