VW air rule violation allegations 'stunning,' $18B fine unlikely

The big automotive news today was the US federal allegations that VW quietly and illegally installed software on approximately 482,000 diesel vehicles sold in the United States so that they would not return substandard results on government emissions tests. To say the least, this is potentially a very big deal. You can read the details of the government's allegations here. The problem seems to be with the NOx trap. Sam Abuelsamid, a former AutoblogGreen editor who is now a senior research analyst at Navigant Research's Transportation Efficiencies program, told me that there were some hints that VW's diesel emissions strategy had issues a while back. The vehicles affected by today's announcement are all equipped with the 2-liter, 4-cylinder TDI, he said. They all have the lean NOx (nitrogen oxides) trap, whereas all other current modern diesels use urea to treat NOx emissions. "When VW launched those vehicles, I went to the TDI launch program in Santa Monica and asked them if they were going to put the diesel engine into the Tiguan because that would be an ideal application," he said. "They said no, because it would be too heavy. Turns out, the NOx trap was enough to meet the emissions standards in the smaller cars, but not the Tiguan. That seems to be where the problem is, in the NOx trap. All the other big VW and Audi diesels, they use urea, just like BMW and Mercedes do." Abuelsamid added that, in California, to do an emissions test, testers don't stick a probe up the exhaust, as you would suspect. Instead, they just do a visual test to make sure nothing was tampered with and then plug a scanner into the OBD-II port to read the codes. The news today basically says that the cars were programmed to send out false codes, giving readings that testers are looking for instead of what's actually going on. "That's the background, as far as I know at this point," he said. This could be "a black eye on the auto industry." - John O'Dell Speaking at the AltCar Expo in Santa Monica just hours after the news first broke this morning, Edmunds.com's John O'Dell said the Fed's allegations were "stunning." The idea that VW might have gamed the system, he said, "underscores how important EPA clean air numbers are, that a company would allegedly stoop to this to try and meet them. Obviously, people are paying attention to that sort of thing.

Aurora's Chris Urmson on autonomy — that's one way to avoid speeding tickets

Although this year's CES was full of companies announcing and exhibiting their real and conceivable self-driving car technologies, while actual self-driving cars from Aptiv-Lyft were giving conventioneers 400 rides around town, the biggest news came when Volkswagen Group — and recognize this is the entire group, not just the brand — and Hyundai announced that they'd both partnered with Aurora Innovation. While the VW announcement was vague — "The collaboration brings the two companies together to realize self-driving electric vehicles in cities as Mobility-as-a-Service (MaaS) fleets" — Hyundai provided a concrete goal: "a strategic partnership to bring self-driving Hyundai vehicles to market by 2021." You may not have heard of Aurora, which has been described in some news accounts as "mysterious." But Aurora Innovation has been in business since December 2016, and it is to autonomous technology what the 1927 Yankees are to baseball. The three leaders of the company are Chris Urmson, co-founder and CEO, who had previously been chief technology officer for Alphabet Self-Driving Cars; Sterling Anderson, co-founder and chief product officer, who had directed the development of Tesla Autopilot; and Drew Bagnell, co-founder and chief technical officer, who had been autonomy architect and perception lead at the Uber Advanced Technology Center. We had the chance to sit down with Chris Urmson after he appeared onstage at a Hyundai press conference. He shared his insights on Aurora's approach to automated driving. Initial deployment of self-driving cars? "We think the first place this technology comes to market in in the transportation services or ride-hailing applications, but that's for our partners to decide." (Ride-sharing is a strategy a lot of players in the field are shooting for, as round-the-clock use is one way for paying for what will initially be a technology too costly for private ownership.) Transporting goods or people? "I personally — and as a company — am more excited initially about moving people around. Urban mobility. That's where you see the largest social impact. And it provides better access to mobility for people." Can you create a car that doesn't crash? "It is a fundamentally hard problem because other operators on the road can behave erratically at any moment. For example, if you are in a two-lane, opposing-traffic road, if you want to be safe, you don't drive there, ever.

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.
