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.

VW takes world sales crown from Toyota for first half of 2015

Despite uncertainty in major markets like Russia and China, Volkswagen is wearing the global sales crown for the first half of the year to overtake Toyota. Through the first six months of 2015, VW sold 5.04 million vehicles, which only narrowly beat its Japanese rival's 5.02 million, Reuters reports. The half-year trophy also placed the German brand one step closer to the goal of being the world's largest automaker. VW can't just cruise through the second half of 2015 to continue wearing the crown, though. The company is a major player in China, and that might start to be a disadvantage soon. Auto demand there is expected to be weak for the rest of the year, which could mean dire effects for companies around the world. According to Reuters, the Western European market shows few signs of a sudden surge, either. To turn things around, VW is working on a massive realignment to be more responsive by organizing its 12 brands under four separate holding companies. One factor in VW's favor is that Toyota is facing its own sales struggles across the globe. In the last fiscal year, the Japanese automaker had growing profits but actual volume was down. At the time, the company predicted a drop to 8.9 million vehicles for the current fiscal period. According to Reuters, Toyota has had problems growing in emerging markets and dealing with higher taxes on small vehicles in Japan. For all of 2014, Toyota held the sales trophy with 10.23 million sales, and VW was in second place with 10.14 million. General Motors came in third with 9.92 million. The year was the first time that VW or Toyota had ever surpassed 10 million vehicles over the stretch of a calendar. Related Video:
