Are more diesel scandals about to erupt?

More automakers may soon be embroiled, like Volkswagen, in diesel emissions scandals. According to the Daily Kanban, either the International Council on Clean Transportation (ICCT) or the Deutsche Umwelthilfe (DUH) will soon announce from 10 to 15 more cases of automakers cheating national diesel emissions rules. The outlet says three of the incidents are attributed to Opel. Studies conducted by the DUH, the University of Applied Sciences in Bern, Switzerland, and the UK's Leeds University found that Opel's diesel Zafira, Corsa, and Vectra models emit more NOx than European regulations allow when tested in ways that go beyond the European testing protocol, such as when done on a four-wheel rolling road instead of a two-wheel rolling road. Opel said the accusations had no merit. Specifically on the Zafira, the DUH asked Opel about the emissions findings, and Opel said that no General Motors software contains any measures to enable cheating. Opel then tested a Zafira of its own "both on a two- and a four-wheel roller dynamometer," finding that "The emission behavior determined in each case does not differ from one another." That makes this a case of he-said-she-said for the moment. The Daily Kanban's sources say the cheating methods "range from the crude to the highly sophisticated," with those at the latter end complex enough to render Volkswagen's methods "pedestrian." As for any automakers who might be named, the matter of real-world emissions exceeding a legal limit doesn't mean a carmaker has designed systems that cheat, it might mean the company designed the car to pass a test.

EPA upping its game amid Volkswagen probe

In the wake of the Volkswagen emissions-cheating scandal, the Environmental Protection Agency vowed to crack down on the auto industry with renewed vigor. That process has started. Janet McCabe, the agency's assistant administrator, said Tuesday that the EPA has already obtained a range of vehicles for testing purposes and that its enforcement staff is working as quickly as possible to determine whether other automakers are gaming emission results. "That's another detail we'd rather be obscure about, so that we can make sure people don't know what we're doing." For now, she said the agency is focused on diesel vehicles. But the scope of the new examinations could broaden to include gasoline-powered cars. The renewed efforts could include more light-duty vehicles or focus on heavy-duty trucks. The testing procedures could use dynamometers or portable emissions equipment. Right now, pretty much everything is a possibility. "We're going to become unpredictable, we're upping our game and we're going to use the whole range of technology that we have," she said. That technology now includes a heavy-duty truck chassis dynamometer at the EPA's national Vehicle and Fuel Emissions Laboratory in Ann Arbor, MI. Officials unveiled the $3 million piece of equipment Tuesday and hailed it as the first of its kind in North America. A Freightliner Super Truck, which boosted its fuel efficiency to 12 miles per gallon with the help of a $40 million federal grant, rolled onto the dynamometer in a ribbon-cutting ceremony Tuesday. McCabe said the new dynamometer will allow the EPA to assess the performance of the entire truck – not just its engine – and help engineers test 18-wheel tractor trailers measure, hydrocarbons, greenhouse gases, carbon monoxide and more. In the past, it took about a week for engineers to remove an engine from a truck and prep it for testing. With the new equipment, drivers can open a garage door and drive the rigs straight onto the dynamometer. A wealth of new, real-time data will be helpful as the EPA works with the National Highway Traffic Safety Administration in planning for the second phase of the government's greenhouse gas emission and fuel-efficiency standards for medium and heavy-duty engines and vehicles – a process now underway. While there's been a crush of attention on Volkswagen's scheming to circumvent emissions test, in the real world, it's these medium and heavy-duty trucks that are the bigger polluters.

'Clean Diesel' leaves dirty taste for green-minded VW owners

Volkswagen developed the advertising campaigns for its "Clean Diesel" cars far better than the actual technology. In dozens of complaints filed with the Federal Trade Commission in September, green-minded consumers said they were enticed into buying diesels by the company's advertising, which touted the environmental benefits of new diesel technology. Those alleged benefits convinced many to buy cars they otherwise would not have considered. In actuality, Volkswagen installed secret software in its cars that allowed the company's diesels to brazenly circumvent emissions standards. For environmentally conscious consumers, those decisions backfired. Instead of helping the environment, they drove cars that polluted at up to 40 times beyond the legal threshold for certain emissions. Now, those consumers are angry. They've asked the Federal Trade Commission to investigate Volkswagen for alleged deceptive advertising, and are hoping the federal agency can intervene and force Volkswagen to either buy back their compromised cars or negotiate trade-ins on favorable terms. An FTC spokesperson confirmed the agency is investigating. Many of those who wrote or called the agency said they felt like they had nowhere else to turn. For green-friendly drivers, it wasn't only about the money. It was also about the betrayal. "I am ashamed to drive this car on the road, as doing so is evidence that I have been taken for a fool." "It's awful for the environment," wrote one consumer from Shreveport, Louisiana, on September 24, days after the diesel scandal unfolded. "It's caused me anxiety thinking about the amount of emissions I have been producing." The motorist's comments echoed others filed with the FTC. Many owners felt trapped with cars they couldn't sell and cars they felt they could no longer drive in good conscience, knowing they spew nitrogen oxide at levels that violate the Clean Air Act. "I do not see how I can drive it knowing highly toxic pollutants are being produced," wrote another driver from Middletown, Rhode Island. "I have not driven the car since this news came to light." The two statements were among the 89 filed with the FTC's Consumer Sentinel Network in the week following the Environmental Protection Agency's announcement that Volkswagen had admitted rigging approximately 482,000 cars in America with software that allowed them to cheat emissions testing.
