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.

Winterkorn not under official investigation in Germany

Prosecutors for the state of Lower Saxony in Braunschweig, Germany, are now saying that former Volkswagen CEO Martin Winterkorn is no longer specifically under investigation for his role in alleged fraud related to the automaker's diesel emissions scandal. The lawyers are clarifying that there's no formal inquiry into the exec because there's not yet enough evidence to establish a suspicion of wrongdoing, Bloomberg reports. However, they are still looking into VW's actions. Earlier this week, the prosecutors announced they had begun an initial investigation into Winterkorn for alleged fraud in the emissions regulation evasion. At that time, there were reportedly 12 complaints asking the lawyers to look into the case, including one from VW. Under German law, only a person could be charged for the potential crimes, rather than a whole company. "An initial suspicion must be based on facts, and you must begin an investigation before you can establish the facts," Christoph Schalast, a professor at the Frankfurt School of Finance, said to Bloomberg. Meanwhile in the US, the investigation continues into VW. The Department of Justice has the support from at least two senators to pursue criminal and civil charges against the company. The attorneys general in at least 29 states are also looking into things. Meanwhile, lawyers are building a class-action lawsuit, as well. To help in its defense, the automaker is employing the help of the same firm that defended BP during the Deepwater Horizon oil spill. Related Video:

Volkswagen Golf Variant Concept R-Line puts the sport in SportWagen

With the introduction of the newest Volkswagen Golf Variant, we get an early look at what will most likely be the next-generation Jetta SportWagen here in the US. To further wet our appetities, VW is now teasing something a little sportier with the Concept R-Line. Looking the part of a GTI wagon (or a stretched Golf R), the Golf Variant Concept R-Line has a production-ready appearance that has us hoping we'll see this sporty wagon sooner rather than later.
The R-Line starts off with a new fascia that isn't quite as aggressive as the recently introduced GTI, but it gives the new styling some extra punch. Below the fascia is a lower splitter that visually carries back into the rocker panel extensions, and the rear of the car gets some bright exhaust tips and a rear diffuser. The Lapis Blue Metallic paint job probably does enough on its own to add a sporty flair to the Golf wagon, and it's all finished off with 18-inch split-spoke wheels. Inside, the Concept R-Line shows off sport seats wrapped in carbon leather featuring blue nappa inserts in the middle.
Rightfully so, VW brought the Concept R-Line to Geneva with its TDI and 4Motion all-wheel-drive system. A sporty, all-wheel-drive diesel wagon? Yes, please. Scroll down for the full press blast with all the details.
