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.

Winterkorn steps down as CEO of Porsche SE

Martin Winterkorn's departure from all things related to the Volkswagen Group is nearing completion. After having stepped down as chairman of the automaker's executive board nearly a month ago in the wake of the automaker's diesel emissions scandal, he's now leaving the direction of the company's principal shareholder, as well. After VW acquired Porsche (the automaker) several years ago, and in turn was principally acquired by Porsche (the holding company), the latter installed Winterkorn as its chief executive officer in order to cement ties between the parties. He's served as chairman of the executive board (German-speak for CEO) at Porsche Automobil Holding SE ever since, but he's now officially resigned from that position. In his place, the holding company has named Hans Dieter Potsch as its new chief exec. Potsch was also recently named as chairman of the supervisory board of the Volkswagen Group, having served until now as CFO of both VW AG and of Porsche SE. Winterkorn's principal successor at the helm of daily operations at VW is Matthias Muller, formerly CEO of the Porsche auto brand and now CEO of the entire VW group. The development brings Winterkorn's exit closer to completion. However the departing executive still, for the time being, remains at the head of group divisions Audi, Scania, and Truck & Bus GmbH. We don't expect it will be much longer, however, before he formally resigns from those chairmanships as well.

German carmakers recall 630,000 diesel vehicles in Europe

Mercedes, Opel, Porsche, and Volkswagen will recall over 630,000 cars in Europe, according to reports Friday. No diesel car has been able to get under the legal emissions limit in real-world driving, according to a German government investigation. While only Volkswagen Group has been using a specific "defeat device", other carmakers have been playing with their exhaust gas recirculation (EGR) systems. Depending of the manufacturer, the systems have been cut off at a certain temperature. In a specific test cycle the systems operate to fulfill the legal requirements, but in everyday use the limits are exceeded. According to the magazine Der Spiegel, the supplier Bosch is behind this programming and has provided it to all German automakers. The mentioned carmakers have announced recalls, but many other manufacturers are also mentioned by name in the report, including Alfa Romeo, Chevrolet, Dacia, Fiat, Ford, Hyundai, Jaguar, Jeep, Land Rover, Nissan, Renault, and Suzuki. PSA Group, which produces Peugeot, Citroen, and DS cars, declared yesterday that its offices were raided following an emissions investigation.
