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.

Dieselgate defeats Audi's Le Mans racing dynasty

Referring to what the automotive press has dubbed "Dieselgate", Audi's Chairman of the Board of Management Rupert Stadler announced that Audi is pulling out of the FIA World Endurance Championship by the end of the 2016 season. This means Audi will no longer compete in the 24 Hours of Le Mans. However, that doesn't mean Audi is through with competing on the world stage. Instead of fossil-fuel-powered prototype racing, Audi will now "focus on the things that will keep (it) competitive in the years ahead", namely Formula E. Having worked together previously with Audi tuner ABT and component manufacturer Schaeffler in Formula E, the company is now turning Team ABT Schaeffler Audi Sport into a fully factory-backed outfit. Audi's DTM efforts with the RS 5 DTM will remain untouched for the time being, and the company hasn't made a decision yet as to whether its World Rallycross Championship with the Audi S1 EKS RX quattro will continue. Audi has competed in Le Mans prototype racing for 18 years, during which it secured 13 Le Mans wins. Out of 185 races contested by Audi's LMP cars, they racked up an impressive 106 wins. Audi's victory in 2006 was the first with a TDI engine, and the first hybrid-engine win was claimed in 2012. From 2000 to 2008, Audi won nine consecutive American Le Mans Series titles.
