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.

Top 10 small cars with the longest total driving range

Editor's Note: Since this article was originally posted in the spring of 2015, much has changed in the automotive landscape, especially among those shopping for small car economy. With thanks to Volkswagen for their blatant cheating – and subsequent cover-up – on diesel emissions, the largest player in the diesel passenger car segment isn't playing – they're paying; billions are going for both car buybacks and federally-imposed penalties. And for a few VW execs there exists the very real possibility of jail. With the absence of a big player and the abrupt entrance – via Chevy's new Bolt – of an affordable EV with 200+ miles of range, we've limited the diesel listings to Jaguar's new XE. And for those wanting an updated look at efficiency and range, Autoblog has it – or the EPA has it. Long before electric vehicles were part of the mainstream conversation, car lovers and skinflints alike would boast about the total range of their vehicles. There's something about getting farther down the road on one tank of gas that inflames the competitive spirit, almost as much as horsepower output or top speed. Of course, the vehicles with the very best range on today's market are almost all big trucks and SUVs; virtually all have the ability to carry massive reserves of fuel. Top up a standard Chevy Suburban and you can expect to travel almost 700 miles (you'll need to stop before the Suburban stops...), while a diesel-fed Jeep Grand Cherokee manages almost as many. But what about vehicles that are smaller? The EPA has, essentially, three classifications for 'small' vehicles: Minicompact, Subcompact and Compact. All three are measured based on interior volume, meaning that some cars with rather large exterior dimensions and engines slot in next to traditional small cars. But even though impressive GT coupes from Porsche, Bentley and Mercedes-Benz may have much larger gas tanks to feed their powerful engines, that capacity is offset by higher rates of consumption... in most cases. We used the EPA's Fuel Economy Guide for model year 2017 cars as a start, calculating the official highway miles per gallon rating with each vehicle's tank capacity. The resulting numbers aren't necessarily real world, but they do offer a spectrum for total theoretical range. The eventual top ten surprised me on a few occasions, and comprised quite a varied list of vehicles. 10.

How the Volkswagen cheating probe developed

Fallout from Volkswagen's revelation that it engaged in cheating on emissions testing continued Monday, with the company's stock falling more than 15 percent and a Congressional subcommittee announcing an investigation into the German auto giant's conduct. Both the Environmental Protection Agency and California Air Resources Board served Volkswagen with a Notice of Violation on Friday, saying the company intentionally circumvented emissions standards by using "defeat devices." Here's a look back at the agencies' emissions enforcement history and how the charges involving Volkswagen developed. August 1998 – Honda spends $267 million to settle charges it violated the Clean Air Act by disabling "misfire monitoring devices" installed on more than 1.6 million vehicles. Ford spends $7.8 million to settle a charge it violated the Clean Air Act by installing defeat devices on 60,000 Ford Econoline vans. May 2014 – Working with the International Council on Clean Transportation, researchers at West Virginia University find significantly higher in-use emissions from a 2012 Jetta and 2013 Passat and alert the EPA to their findings. November 3, 2014 – Korean automakers Hyundai and Kia agree to pay a $100 million fine for overstating the fuel economy on several of their models by as much as six miles per gallon. In announcing the fine, government officials sought to make an example of the two companies to deter further cheating. VW officials admit the vehicles were designed with a defeat device to "bypass, defeat and render inoperative elements of the vehicle emissions control systems." "This type of conduct quite simply will not be tolerated," said then-Attorney General Eric Holder. "And the Justice Department will never rest or waver in our determination to take action against any company that engages in such activities – whenever and wherever they are uncovered." December 2, 2014 – Following discussions that stemmed from West Virginia University's findings, Volkswagen agrees to initiate a recall of 500,000 cars. The company says a software update will fix the nitrous oxide trap technology and selective catalytic reduction technology causing the cars to miss emissions thresholds. May 6, 2015 – CARB wanted to see whether the software fix implemented by Volkswagen worked. Using portable emissions measurement systems, the regulatory officials found NOx emissions were still significantly higher than expected.
