ACEEE strips away VW's green car scores

The American Council for an Energy-Efficient Economy (ACEEE) is confirming that the Volkswagen diesel-emissions scandal has put a black mark on its green ratings. As a result, the group is pulling VW diesel vehicles off of its "Green Scores" list because it was recently revealed that VW diesels might be emitting as much as 40 times the nitrogen oxide (NOx) emissions during normal driving as the official test results show. The ACEEE added that other German makers of diesel vehicles' "Green Scores" are safe, for now. Diesels from VW and the company's Audi division didn't exacatly top the ACEEE's list of greenest vehicles for 2015. That honor went to electric vehicles like the Smart ForTwo ED, Chevrolet Spark EV and Fiat 500E. The Toyota Prius C hybrid snuck in at number 4, while the Nissan Leaf battery-electric took the fifth spot. That said, the VW diesels did perform pretty well, according to the group. "These scores are no longer reasonable estimations of the environmental impact of the Volkswagen diesels. Volkswagen's diesel cars have performed well on ACEEE's annual rankings since 2009, hovering just below our list of the top twelve "Greenest" vehicles with Green Scores in the high 40s," wrote Shruti Vaidyanathan, senior transportation researcher at the ACEEE. "However, a 40-fold increase in on-road NOx would mean that these vehicles did not deserve those high Green Scores." For those curious, the Ram 2500 pickup topped the ACEEE's "Meanest" vehicle of 2015, followed by the Chevrolet G2500 Express/GMC Savana. No diesels showed up on that list of environmentally-damaging vehicles. You can read the ACEEE's statement on VW below. Why we are suspending Volkswagen diesel Green Scores on greenercars.org by Shruti Vaidyanathan, Senior Transportation Researcher On September 18th, the Environmental Protection Agency (EPA) slapped the Volkswagen Group with a notice of violation (link is external) of the Clean Air Act for circumventing EPA emission standards for nitrogen oxides (NOx). Volkswagen has now acknowledged using so-called "defeat devices" on its diesel cars that turn on full emissions control technologies while in testing mode but allow the vehicles to emit nitrogen oxide levels up to 40 times the certified level during normal operation.

Ex-Fiat exec: VW diesel scandal will hurt plug-in hybrids

It doesn't sound right at first blush, but former Fiat executive and noted diesel-powertrain expert Rinaldo Rinolfi thinks that plug-in hybrid sales may be more impacted by the VW diesel-emissions scandal than diesel sales. Rinolfi, who worked for Fiat for 40 years, told Automotive News Europe, said that the Euro 6 emissions rules that went into effect in 2015 have already increased diesel-engine production costs enough to raise prices and ultimately flatten demand. By the end of the decade, diesel-vehicle sales will settle in at a 40-percent market share of new European vehicles, and that was going to happen with or without the scandal. "Every carmaker has found ways to achieve fuel consumption and emissions results that have progressively diverged from the real driving conditions." - Rinaldo Rinolfi Makers of plug-in hybrids have more to lose, though, because every PHEV maker has figured out a way to keep emissions figures artificially low, Rinolfi said. Under New European Driving Cycle (NEDC) standards, PHEVs can be tested part of the time with the electric motor in action, meaning emissions get driven down to 30 percent to 40 percent less than real-world figures. With the VW scandal pushing regulators to use real-world figures, those PHEV emissions numbers are expected to rise substantially. To a lesser extent, hybrid emissions figures are also tested as artificially low. "Over the years, even without defeat devices, every carmaker has found ways to achieve fuel consumption and emissions results that have progressively diverged from the real driving conditions the customer experiences," Rinolfi said in the Automotive News Europe interview. Rinolfi is a little sunnier about compressed natural gas (CNG) vehicles, estimating that CNG emissions are as much as 25 percent lower compared to conventional vehicles. As for battery-electrics, he's not so optimistic, estimating that there needs to be at least a tenfold improvement in energy efficiency for EVs to be truly competitive with conventional vehicles. "I've been waiting for a true breakthrough for the past 25 years, but I've not seen it yet," Rinolfi said about EVs in the Automotive News Europe interview.

VW recalls 420,000 vehicles for driver's airbag failure

Volkswagen is issuing a recall for 420,000 vehicles in the US because of a potential failure of the driver's side airbag. The campaign affects German-made examples of the 2010 Passat; the 2010-2013 Eos and Jetta; the 2010-2014 CC, Tiguan, and US-produced units of the Passat; the 2011-2013 Jetta SportWagen; and the 2011-2014 Golf and GTI. There are no reports of accidents or injuries related to this issue. Specifically, this problem comes because the steering wheel clock spring can be contaminated by debris, which moves the part's guide loops out of position. This can cause a tear in the electrical cable that controls the driver's airbag. If this happens, a warning light would illuminate, but the safety device would not deploy in a crash. VW is still identifying all of the affected VINs and developing a fix. The company plans to notify owners once everything is known.

As such, Volkswagen of America today notified the National Highway Traffic Safety Administration (NHTSA) that it will be issuing a voluntary safety recall affecting the steering wheel clock spring on approximately 420,000 Volkswagen vehicles in the U.S. Certain 2010-2014 Model Year Volkswagen CC Certain 2010-2013 Model Year Volkswagen Eos Certain 2011-2014 Model Year Volkswagen Golf/GTI Certain 2010-2013 Model Year Volkswagen Jetta Certain 2011-2013 Model Year Volkswagen Jetta SportWagen Certain 2010 Model Year Volkswagen Passat (German Production) Certain 2010-2014 Model Year Volkswagen Passat (U.S. Production) Certain 2010-2014 Model Year Volkswagen Tiguan On certain vehicles, the steering wheel clock spring could become contaminated with long hair or long fibers which may cause a displacement of the internal guide loops. When the guide loops are dragged out of position, they may apply tension to the internal flat cable and cause it to tear. Should the cable tear, the electrical connection to the driver's front airbag may be lost, causing the airbag monitoring indicator light to illuminate. In a crash that warrants a driver front airbag deployment, the airbag will not deploy, leading to a risk of driver injury.
