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.

CARB found another emissions-defeating device, this time from Audi

The California Air Resources Board has discovered another emissions-cheating device on an Audi earlier this summer, reports German newspaper Bild am Sonntag. The device is different from the software found in the VW Group's diesel-powered engines, as it alters the way the cars' automatic transmission shifts. The latest device, according to Bild am Sonntag, measures how far the cars' steering wheel is being turned. If the wheel is turned less than 15 degrees, indicating that the vehicle is being tested in laboratory conditions, a program in cars with certain automatic transmissions changes the way the gearbox shifts. The change in the transmission allows the engine to produce less carbon dioxide than when driving in normal conditions. When the wheel is turned more than 15 degrees, the program automatically turns off, claims Bild am Sonntag. The paper reports that Audi took the software out of its vehicles, which was used in both diesel- and gasoline-powered vehicles in Europe and the US, earlier this May after CARB discovered the program on one of the automaker's older cars. Several engineers that were connected with the emissions-cheating device have already been suspended, reports Bild am Sonntag. As the German newspaper points out, the device, which is fitted to certain Audis with an automatic transmission, is different from the cheat devices found on the automaker's 3.0-liter TDI turbodiesel V6 engine and Volkswagen's 2.0-liter turbodiesel motor, even those were also designed to beat emissions tests. The 3.0-liter engine is found in the Audi Q7, Volkswagen Touareg, and Porsche Cayenne models. Audi didn't immediately respond to our request for a comment.

Investors storm Volkswagen with $9 billion in lawsuits

Volkswagen's investors are latest group to take up pitchforks against the embattled automaker, and they're seeking $9 billion in damages, Reuters reports. The investor lawsuits were filed in a court in Braunschweig, Germany, near Volkswagen's Wolfsburg headquarters. On Monday, the first business day following the anniversary of the emissions revelations, the court received 750 lawsuits alone. All told, about 1,400 lawsuits have been filed. The largest single claim totals $3.7 billion and was filed more than six months ago. The lawsuits stem from complaints that Volkswagen didn't divulge information on the cheating software to investors quickly enough. Volkswagen has said that it hasn't broken any capital market laws. The $21.5 billion the company set aside to weather the storm may not be enough. The consumer fix is estimated to run the company $14.7 billion, either through buybacks or a fix that still seems unclear. In addition to the lawsuits, Volkswagen CEO Matthias Mueller confirmed that Audi boss Rupert Stadler is under investigation regarding the scandal. Mueller refused to give further details, but this shouldn't come as a surprise to anyone. Audi has admitted that its 3.0-liter V6 was equipped with the same emissions-cheating software as the 2.0-liter four-cylinder diesels. Stefan Knirsch, Audi's head of development, has been suspended as part of the overall investigation. Knirsch took over duties after his predecessor quit. Knisch was previously head of engine development at Audi. Related Video: News Source: Reuters Green Hirings/Firings/Layoffs Audi Volkswagen Emissions Diesel Vehicles vw diesel scandal
