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.

European RS6 Avant ad features diesel-hybrid R18 racecar

We'd be just as happy to casually walk back to an RS6 Avant as anybody, but Audi's commercial for its fastest ass-hauling wagon takes casual to another level. The RS6 isn't even seen until more than two-thirds of the way through the 46-second German commercial, but Audi seduces us long before that with the R18 E-tron Quattro diesel-hybrid endurance racer juxtaposed into scenes of everyday life. Since when can you be picked up at the airport or drive peacefully to a riverbed in a racecar?
The German automaker cashed in on childhood dreams its nearly flawless endurance-racing pedigree big time for the advertisement - and it works, even though we realize the RS6 drinks gasoline and isn't a hybrid. It does have Quattro four-wheel drive, however. But the commercial makes us want the beautifully pragmatic long-roof with 550 horsepower all the more, especially since Audi currently has no plans to bring it to the US. Please say it ain't so!
Even if the US doesn't get an RS6 Avant, we're happy to indulge in commercials like this. Be sure to watch it below.

Audi Q7 to be first diesel plug-in from VW group

Lending credence to prior reports, the next Audi Q7 will be available with a diesel-powered, plug-in-hybrid powertrain, Automotive News claims, after speaking to a source in the Volkswagen Group. Both the gas and diesel-powered Q7 will debut in 2015, with the diesel PHV to arrive after that. Unlike Europe's other plug-in diesel, the Volvo V60, Audi's Q7 will be sold on both sides of the Atlantic, the source told AN. You can see a few spy photos of the Q7 PHV above. Audi research and development boss Ulrich Hackenberg previously confirmed that diesel plug-ins would be arriving earlier this year, although it wasn't clear which models the ultra-efficient powertrains would be offered on, or which of those would be offered here in the US. Time to play the waiting game...
