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.

Audi A3 gets Virtual Cockpit next year

Want the Audi TT's nifty virtual cockpit but need a more practical car? Great news for you, as Audi will bring the reconfigurable, all-digital instrument cluster to the A3 next year. The news was confirmed to our friends at Car and Driver, courtesy of the head of Audi's electronics department, Ricky Hudi. "In the future, there are not so many [of our] cars that will not have it integrated, even into the smaller cars. Next year in the A3, we will also integrate the Virtual Cockpit," Hudi told C/D. Now, don't go thinking you'll be able to pick up a basic A3 and be able to enjoy the new instrument cluster, like you can on the TT and R8. This is going to be an up-market option, just like it is on the new Q7. "If they choose a higher engine or a higher, well-equipped car then they will choose it – no doubt. The price reduces very fast with more people using it and the Virtual Cockpit is an Audi signature now." Related Video:
