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.

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.

Autoblog Minute: VW Emissions Scandal, New Ford Super-Duty

We got our first looks at look at Ford's new Super Duty truck lineup this week but it's Volkswagen that has been dominating the news cycle, as Matthias Muller is named CEO of the embattled automaker. Autoblog's Senior editor Greg Migliore reports on the recap edition of Autoblog Minute. Show full video transcript text [00:00:00] We got our first looks at look at Ford's new Super Duty truck lineup this week but it's Volkswagen that has dominated the news cycle as Matthias Muller is named CEO of the embattled automaker. I'm Senior editor Greg Migliore and this is your Autoblog Minute Weekly Recap. Super Duty is new for 2017. Our first look at these heavy duty trucks showed increased cab space for passengers, and [00:00:30] a lighter aluminum frame. Ford insists these changes will provide customers with increased towing capacity and fuel efficiency. The all-new Super Duty will be built at Ford's Kentucky Truck Plant, and it goes on sale in late 2016. Now, in case you missed it Volkswagen is under fire for gaming EPA emissions testing. A massive government recall is in the works and the world's top-selling automaker is looking at significant losses in both car sales and its stock value. On top of losing billions of dollars, Volkswagen is also facing [00:01:00] legal issues. And this week we saw Martin Winterkorn step down as CEO of Volkswagen Group. These changes mark just the beginning of VW's arduous process of rebuilding consumer trust. Those are the highlights from the week that was. Be sure to check out my full recap this Saturday, plus some added insight on the Buick Cascada and its pricing strategy. For Autoblog, I'm Greg Migliore.
