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 bringing all-electric CUV to Frankfurt

Audi will introduce a new, all-electric, MLB-based concept this September at the 2015 Frankfurt Motor Show. According to CEO Rupert Stadler, production of the vehicle this concept foreshadows will eventually hit 10,000 units. Stadler isn't the only Audi exec dropping details on the company's high-riding EV. Research and development boss Ulrich Hackenberg let slip that the all-electric "sports activity vehicle," might be followed by both a gas-powered plug-in variant and hydrogen-fuel-cell model. According to Hackenberg, the production model will arrive in early 2018, cover about 310 miles per charge, and target the upcoming Tesla Model X. Look for more on this new model and the concept that will precede it as the Frankfurt Motor Show approaches. Related Video:

Audi billboard tracks pedestrians like prison escapees

Audi's adaptive Matrix LED headlights can actively dim and direct light around the road to make driving safer at night. Unfortunately, the tech runs afoul of Department of Transportation rules, so it isn't currently available in the United States. For an idea of what you're missing, a marketing stunt for the new A4 in Belgium is illuminating the night and making pedestrians in the intersection more visible, and safer. The only problem is, it also makes them look like fugitives making an escape. From a giant billboard near the Brussels Central Station, the LEDs from a massive Audi A4 can light up whole intersection. Whenever a pedestrian or cyclist enters the area at night, they are tracked the whole way in a radiant pillar of blue luminescence. Based on this clip, the lights look bright enough to temporarily blind some passersby. Despite the unintended consequences, the stunt is still a very visible demonstration of Audi's headlight technology. Related Video: The video meant to be presented here is no longer available.
