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.

Nick Murray's problematic Porsche 911 shows the power of a viral video

When Nick Murray took delivery of his 2013 Porsche 911 Carrera S in June 2013, he had saved for it for the past five years. He didn't just pluck a random 911 off a dealer lot. He specially ordered his car with thousands of dollars in extras tailored just to him, and he captured all of the options on his YouTube channel. The love affair didn't last long. Eventually the channel became a place for Nick to air his growing list of grievances about his deteriorating 911. Eventually, his mix of righteous indignation and sarcasm went viral.
By late December, he had already had four warranty repairs done on the car. Things got much worse in March. The computers began resetting whenever Nick drove over large bumps. There was also an acrid, electrical smell that occasionally permeated the cabin. Murray filed for Lemon Law protection. Porsche Cars North America contacted him for the first time to fix the problem, but it didn't help.
Things culminated in April when Murray put up a new video that showed more troubles. He began arbitration with Porsche and asked for either his full purchase price back or an exact replacement. The company countered with a portion of what the car was worth, based on its mileage. Murray refused and turned to his YouTube watchers for help. He asked them to spread the word, and the video went viral with over 800,000 views as of this writing. Supporters posted it multiple times on Porsche's Facebook and Twitter sites.

VW adding particulate filters to gas engines

Volkswagen is working hard to overcome the PR disaster that is its diesel emissions scandal, and part of its efforts is focusing, weirdly, on petrol engines. Starting in June 2017, the embattled German automaker will add particulate filters to the gas-powered Volkswagen Tiguan and Audi A5. The change will eventually impact nearly every direct-injected gas engine the VW Group makes. Audi? Particulate filter. Seat? Particulate filter. Even Bentley is going to get the tech, all in a bid to reduce soot emissions by 90 percent. In fact, by 2022 VAG expects 7 million of its vehicles to boast the emissions-cleaning tech, which has long been a fixture on diesel engines. "Following increases in efficiency and lower CO2 output, we are now bringing about a sustained reduction in the emission levels of our modern petrol engines by fitting particulate filters as standard," Volkswagen Group research and design boss Dr. Ulrich Eichhorn said in a statement. "In the future, all models will be equipped with the latest and most efficient SCR catalytic converter technology." VW's initial rollout focuses on the 1.4-liter, turbocharged Tiguan and the 2.0-liter, turbocharged A5. Considering the popularity of the 2.0-liter across the VW range, we'd expect it's only a matter of time before VW expands its particulate filters tech to additional gas-powered vehicles.
