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.

24 Hours of Le Mans an on-and-off love affair

There was little usual about this year's 24 Hours of Le Mans - intermittent rain in the weeks before the race meant cars didn't get on track as much as they wanted, and intermittent rain during the race meant cars went off track a lot more than they wanted. The race started with a wet track, and one of the records broken because of the random downpours was the number of times the safety car led the field - 11 times this year - although the record of two hours and 53 minutes of lapping behind the safety car, set in 2011, was not eclipsed.
None of that served to dampen the action. With little more than an hour left in the race there were cars still only a few seconds apart fighting for position, leads still changing because of pit stops and everyone drafting anyone they could.
Things didn't go the usual way up front, either - well, not exactly...

Porsche CEO outlines Cayenne diesel US repair proposal

Porsche has announced a plan to fix the emissions issue on the Cayenne with the 3.0-liter diesel V6, and it includes a software update and the replacement of the catalytic converter on some early examples, according to Reuters. The company believes these repairs are enough to make the SUVs emissions compliant, but the automaker's proposal still needs approval from the Environmental Protection Agency and California Air Resources Board before it can implement a recall. This authorization could come by the end of January. Note that the proposed 3.0-liter TDI plan is separate from the 2.0-liter TDI fix that was rejected by CARB on Tuesday. There are around 13,000 Cayennes on the road that the company needs to repair. Models from 2013 and 2014 would require a new catalytic converter and a software update, but those from 2015 and 2016 would just need the new software. "The technical aspects have all been submitted, we will wait whether there will still be proposals for corrections by the Americans," Porsche CEO Oliver Blume said to Reuters. He wasn't sure how long the repair process would take, but suggested less than half of the affected examples would require the upgraded exhaust hardware. Blume indicated to Reuters that Audi actually created this repair plan. The EPA first issued a violation notice against the 3.0 TDI in early November and later broadened it to around 85,000 vehicles from the 2009-2016 model years, including diesel examples of the Cayenne, Volkswagen Touareg, Audi A6, A7, A8, Q5, and Q7. Audi later admitted the engine contained previously undisclosed auxiliary emission control devices. CARB gave the automaker 45 days to come up with a recall proposal to fix the 15,000 affected models in the state. Related Video:
