EPA discovers defeat device in more VW TDI engines

In a sternly worded letter, the United States Environmental Protection Agency has issued a new set of allegations against Volkswagen claiming that so-called emissions defeat software has been found in the company's 3.0-liter TDI V6 diesel engines. This is a completely different engine than the 2.0 TDI that has already been identified as an emissions cheater. In addition to VW, the EPA has included Audi and Porsche in this notification, as the non-compliant engine has been used in vehicles from all three manufacturers from model years 2014 through 2016. The EPA claims that cars equipped with the 3.0 TDI engine know when they are being tested for emissions, and their on-board computers switch into a mode designed to pass the stringent requirements in the United States for diesel exhaust. Vehicles sold in the United States with this engine include the 2014 VW Touareg, 2015 Porsche Cayenne, and 2016 Audi A6, A7, A8L and Q5. The EPA says there are 10,000 vehicles currently on the road with this second defeat device, along with an unknown number of 2016 models either on dealer lots or in the driveways of consumers. According to the EPA, VW's 3.0-liter TDI, like the 2.0 TDI that was found to circumvent US regulations, has code in its computer specifically written to intentionally put the vehicle's engine into a mode that allows it to meet exhaust requirements. When the vehicle is unhooked from testing equipment, it will go back into a mode that emits nine-times higher nitrogen oxide emissions than is allowable under US law. "VW has once again failed its obligation to comply with the law that protects clean air for all Americans," said Cynthia Giles, Assistant Administrator for the Office for EPA's Enforcement and Compliance Assurance. "All companies should be playing by the same rules. EPA, with our state, and federal partners, will continue to investigate these serious matters, to secure the benefits of the Clean Air Act, ensure a level playing field for responsible businesses, and to ensure consumers get the environmental performance they expect." Richard Corey, Executive Officer of the California Air Resources Board, said in a statement, "Today we are requiring VW Group to address these issues. This is a very serious public health matter. ARB and EPA will continue to conduct a rigorous investigation that includes testing more vehicles until all of the facts are out in the open." This story will be updated as new information becomes available.

Volkswagen to 'refit' 11 million diesel vehicles [UPDATE]

UPDATE: This post has been updated with an official comment from Volkswagen of America. In response to its devastating diesel-emissions scandal, Volkswagen will ask some 11 million of its customers to report into dealerships to have their diesel-powered vehicles "refitted," Reuters is reporting. According to new CEO Matthais Muller, customers will be asked to report in "in the next few days" for the refit, although it's not entirely clear exactly what the 'refit' entails. Mueller apparently made the announcement during a closed-door meeting with 1,000 of the German company's top managers, although he didn't explain exactly how the emissions-cheating software would be sorted out, or what impact it would have on the performance of mileage of the company's diesel-powered products. It's expected that the refit work will cost VW $6.5 billion, Reuters claims. "We are facing a long trudge and a lot of hard work," Muller allegedly said. "We will only be able to make progress in steps and there will be setbacks." Autoblog reached out to Volkswagen of America to see when American consumers would be asked to report to dealers, what the refit involves, how long it's expected to take to repair all the cars in the US and globally, and what impact this fix will have on the performance and fuel economy of its diesel-powered cars and SUVs. Unfortunately and unsurprisingly, VWoA wasn't too forthcoming. "We don't comment on media speculation on internal meetings," Volkswagen of America spokesman Mark Gillies told Autoblog, adding, "We don't have any information on what the remedy might be at the moment, but we are working on it as a matter of the utmost urgency."

Will VW's rumored 186-mile EV battery be enough?

Just as there continues to be a horsepower war in the realm of performance cars, there's an ongoing battle over driving range among electric vehicles. Both the Tesla Model 3 and Chevrolet Bolt are promising around 200 miles for a relatively affordable price in or around 2017. Plus, Nissan is reportedly nearing a 250-mile Leaf for about the same time and Ford might be joining the game, too. Volkswagen might be the latest potential challenger with some extra distance possible from its future EVs. According to Hybrid Cars, Volkswagen Chairman Martin Winterkorn tells Bild in Germany that the company is developing a new generation of battery tech with major gains, and it could reportedly provide a range of around 186 miles. That's more than double the current 83-mile EPA certified range for the e-Golf but falls short of the projections from competitors. Winterkorn didn't indicate exactly when this innovation would be ready for production, though. Especially in recent months, the German automaker is making serious moves towards big advancements in battery tech, and the company's platforms are largely already prepped to become EVs. The entire VW Group is reportedly considering moving to a single, unified lithium-ion cell design, and that switch could cut component costs by as much as 66 percent. In late 2014, the German automotive giant also bought five percent of the US-based startup QuantumScape. That business has claimed a staggering 430-mile range from its fireproof, solid-state lithium batteries, but the proof will need to be seen on the road – and in whatever the competition is able to accomplish whenever a car is finally available.
