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.

Volkswagen rolls out all-new Polo R WRC

Volkswagen may have ruled out producing a road-going Polo more potent than the new GTI, but on the rally stage, the Polo R WRC has proven absolutely dominant. Introduced to the World Rally Championship in 2013, the Polo R won ten out of the baker's dozen rallies in its debut season, and all but one last year to win both titles two years running. That's quite an act to follow, and the task falls to the machine you see here. The new second-generation Polo R WRC was just revealed at Autostadt in Wolfsburg. The rally machine has been substantially reworked for 2015, with a new livery, new bodywork and new oily bits. In fact, Volkswagen says it has revised three quarters of the components, and while it has not yet detailed the "many new ideas [implemented] under the bonnet," it has identified the hydraulic gearbox as "the biggest innovation." Further details are still to come, but this is our first look at the new machine with which Sebastien Ogier, Jari-Matti Latvala and Andreas Mikkelsen – who finished last year's championship in first, second and third, respectively – will tackle this year's championship, starting with the Rally Monte Carlo on January 22-25. FIA World Rally Championship (WRC) New technology, new design: presenting the second generation Polo R WRC - World premiere of the 318-hp Polo R WRC in Wolfsburg - Member of the Board, Dr. Heinz-Jakob Neusser, launches title defence - WRC kicks off with the iconic Rally Monte Carlo from 22–25 January Wolfsburg (15 January 2015). In top form, both technically and visually: Volkswagen presented the second generation of the Polo R WRC in Autostadt, Wolfsburg. The works team from Wolfsburg has its sights set firmly on another successful defence of its titles in the FIA World Rally Championship (WRC) with a new car and a new look. Volkswagen completed a clean sweep of all the World Championship titles when the Polo R WRC made its debut in 2013, before repeating this impressive feat last season. Continuity is the key to the driving line-up for 2015: double world champions Sebastien Ogier/Julien Ingrassia (F/F) and team-mates Jari-Matti Latvala/Miikka Anttila (FIN/FIN) and Andreas Mikkelsen/Ola Floene (N/N) will roll down the starting ramp and head onto the first special stage of the year for Volkswagen at the legendary Rally Monte Carlo on 22 January. "The new Polo R WRC has undergone intense further development, both on the inside and the outside," said Dr.
