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.

Audi spending an additional $2.5 billion on expansion through 2019

Every year, it seems the Volkswagen Group announces a new and larger spend to push growth and profit, with Audi a regular recipient of the moolah. That's reasonable, seeing as hauls in 40 percent of Group operating profits. In December last year Audi said it would spend an additional 100 million euros ($122M US) per year through 2018 to develop new models and expand production, targeting 60 models by 2020 and luxury sales leadership. This month Audi said it will boost that by another two billion euros ($2.5B US) over the next five years, for a total outlay of 24 billion euros from 2014 to 2019. Something like 70 percent of those billions will be spent on new models, technology like "connectivity and lightweight construction," and factory expansion at its plants in Ingolstadt and Neckarsulm. Most of the ten models that will plump the lineup to 60 cars will mainly be aimed at the C and D segments, as well as crossovers, the brand's burgeoning portfolio of PHEV models, and all-electric cars that will begin staking ground in the segment. The big spend comes at the same time as Audi is working hard to reduce costs by $2.5 billion to maintain profitability, part of a larger push by VW to cut costs by $6.1 billion by 2017. More than a billion euros will go to new factories in Mexico and Brazil. Work begins on the Mexico plant next year, and when it comes on-line in 2016, Audi's Q5 successor will roll out of its warehouse doors; Audi has already announced it will hire 850 more workers next year in Mexico. When that's done, Mexico's production of German luxury cars will only trail that of Germany, China and the US. The company's Brazil plant will produce the A3 and S3 starting next year, and the brand figures luxury car buying there will triple by 2017.

To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.
