That time when VW thought its diesels were holier than hybrids

When it comes to its diesel engines, Volkswagen was publicly trying to work the regulation system as far back as 2011. That's when the Obama Administration announced stricter US greenhouse-gas emissions standards for 2025. At the time, VW was saying its diesel engines were as clean or even cleaner than hybrids and some plug-in vehicles, The New York Times says, citing former Environmental Protection Agency (EPA) officer Margo Oge. VW did indeed boycott Obama's announcement of the 2025 Corporate Average Fuel Economy (CAFE) standards four years ago. The reason given at the time was that VW's attempt for its diesel engines to get special consideration and extra credits for fulfilling the emissions mandate was ultimately rejected by the EPA. Oge said VW's US executives were conciliatory but the automaker's German officials were "arrogant" in their belief that diesel technology was far superior, from an emissions standpoint, than hybrids or plug-ins. As we know now, that was not the case. Last month, we learned that VW fitted as many as 11 million vehicles around the world with software that programmed its diesel engines to show artificially low emissions levels during testing. In the ongoing fallout, VW has set aside $7.3 billion to address the scandal and the CEO resigned. New VW CEO Matthias Muller says recalls on the diesels in question may go into effect as soon as January in Europe. Meanwhile, among other indignities, Green Car Journal rescinded Green Car of the Year Awards it had bestowed on the 2009 Jetta TDI and 2010 Audi A3 TDI, while Volkswagen's Stock was delisted from the Dow Jones Sustainability Index.

BMW says its diesels are above board

BMW got yanked into the riptide of the Volkswagen diesel scandal thanks to a report in Auto Bild, which Auto Bild has now clarified. On Thursday the German magazine said that when the International Council on Clean Transportation tested the X3 xDrive 2.0d, the ICCT discovered the diesel X3's tailpipe emissions exceeded the European limit by more than 1,100 percent. The key detail, though, is that apparently at no time did the ICCT find that BMW cheated on any emissions tests. No one has explained why the X3 diesel had such high emissions and the ICCT wouldn't comment on the Auto Bild report. But the mag has issued a clarification asserting that in spite of the excessive emissions, there is no evidence BMW engaged in regulatory subterfuge. Every other BMW vehicle ICCT tested was within compliance, but the organization's report from October 2014 - that no one paid attention to - found that nitrogen oxide emissions in 15 vehicles it tested averaged seven times the European limit. The brand's stock is still suffering from the taint. It dropped almost ten percent the day the report came out before rallying to close at five percent down. But on Monday BMW stock closed at 84.01 euros, and as of writing on Friday it's still trying to fight its way back above 80 euros. With so many people still just trying to find out how widespread the the issue is, and trust rather low, it's likely BMW won't be the one dragged down, fairly or not. Related Video:

VW fix would have cost $335 per vehicle

Since the Volkswagen diesel kerfuffle began, Bosch, the world's largest auto supplier, has been hooked up to a bullhorn trying to make sure everyone knows its side of the story. Bosch supplied VW with the engine management testing software, including delivery and metering modules, that VW then used to skirt emissions laws in the US. Bosch told VW in 2007 that it was illegal to use the software in cars it planned to sell yet VW did it anyway, according to reports coming out in German newspapers Bild am Sonntag and Frankfurter Allgemeine Zeitung. That first warning came two years after VW started developing the small-displacement diesel, around the time that the two men pushing its development, then-brand chief Wolfgang Bernhard and engineer Rudolf Krebs, were telling their superiors that the engine needed AdBlue urea injection to pass US emissions. VW cost controllers wouldn't approve the AdBlue solution because it would add 300 euros ($335 US) to the cost of the vehicle. Bernhard and Krebs left the same year that Bosch advised VW about the software, two years before the engine went into production. That's when things get cloudy. A report in Automotive News says that when Martin Winterkorn took over in 2007 as head of the VW Group and brand, he asked Ulrich Hackenberg and Wolfgang Hatz to keep working on the engine, and "[the] engine then ended up in VW Group diesels" with that problematic software still intact. No one has yet pointed any fingers at this latter chain of command, but like a game of Clue, right now they're the professors in the library holding the candlesticks. Warnings didn't only come from the supplier: Frankfurter says VW's initial investigation has found that an engineer issued the same caution to the company in 2011. Neither Bosch nor VW would comment on the reports.
