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.

Daimler says straight up it doesn't cheat on emissions tests

Distancing itself from VW and its diesel emissions scandal, Daimler has put out a statement saying that it has never installed devices on their vehicles that would artificially reduce emissions during a testing process. The company added that it "actively" supports European regulators' efforts to improve emissions-testing methods to better measure emissions during "real" driving conditions. BMW put out a similar statement last week, saying that its diesels are programmed to be tested properly. While Mercedes-Benz diesels were a fixture on US roads in past decades, the company's diesel sales are now concentrated overseas. "We categorically deny the accusation of manipulating emission tests regarding our vehicles," Daimler said in Friday's statement. "A defeat device, a function which illegitimately reduces emissions during testing, has never been and will never be used at Daimler." There's a reason for that sort of straightforward statement. Namely, heads continue to roll at VW after the automaker admitted it manipulated software in its diesel vehicles to pass US emissions testing. VW followed up by saying that as may as 11 million vehicles worldwide may contain that software and has set aside $7.3 billion to address the issue. VW CEO Martin Winterkorn stepped down as well. Take a look at Daimler's press release below. Daimler AG categorically denies any and all allegations of manipulation Stuttgart, Sep 25, 2015 In light of the ongoing assertions from the Deutsche Umwelthilfe (DUH), a non-government organisation, and the related speculation, Daimler AG once again clearly states that: We categorically deny the accusation of manipulating emission tests regarding our vehicles. A defeat device, a function which illegitimately reduces emissions during testing, has never been and will never be used at Daimler. This holds true for both diesel and petrol engines. Our engines meet and adhere to every legal requirement. In light of the written request by the DUH, which was sent to us this morning with a deadline to respond by 3:00 pm (CET), and the seven questions they posed, we can confirm that none of the allegations apply to our vehicles. The technical programming of our engines adheres to all legal requirements. We have no knowledge of measurements that indicate our vehicles did not meet legally required standards.

VW budget sub-brand stuck in limbo over VW standards, costs

Reports in October 2012 claimed Volkswagen had begun investigating the creation of its own budget brand. This came after having failed to purchase Malaysian car company Proton or produce a meaningful partnership with Suzuki, and after watching Renault-Nissan make piles of euro on Dacia and plot the return of Datsun. For VW, more important than the question of what to call it was how to build it profitably and in a way that didn't damage the VW brand. According to a report in Autocar, a satisfactory answer still hasn't been found. The hurdle is how to hit "'necessary' quality and safety levels" at the price points needed to make the venture worthwhile. At the time of the 2012 report, German outlet Der Spiegel said VW was trying to get prices down to 6,000 to 8,000 euro ($7,784 to $10,379 US), about two thousand to four thousand euro under the price of the VW Up and in line with the cost of a 6,790-euro Dacia Sandero in Germany. In March 2013, VW announced, "We want to bring a true budget car to the market in China in the foreseeable future," the most concrete move in that direction after years of planning to make a decision. Working with local Chinese maker FAW, it was predicted that the vehicle in question would appear around 2016, but as of November last year a final vote on it needed to wait until this year because "We are still working on the cost side" and profit possibilities for a car that "has to be durable, it has to be precise, it has to be safe." Even Fiat, another automaker long considering a budget brand beneath its Fiat line-up, wasn't sure how to squeeze any extra money from lower-cost products but was sure that it couldn't be done by manufacturing in Europe. If VW hasn't yet made the math work with a joint venture in China, it will be interesting to see how it might build a European go-it-alone business case.
