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.

1984 Audi Sport Quattro expected to hammer at nearly half a million dollars

The highest prices paid at automobile auctions continue to be claimed by European sports cars, with names like Ferrari and Bugatti forever topping the lists. But what we have here is not quite a sports car. It's more of a hot hatch, but its still expected to fetch between $350,000 and $475,000 when it goes up for auction next month in Arizona. That's because this is no ordinary hot hatch... it's the prototypical hot hatch: the legendary Audi Sport Quattro, one of the most maniacal and dominant homologated rally machines ever devised. Shorter in wheelbase and dartier of handling than the Ur-Quattro that came before it, the later Sport Quattro was built to comply to with the FIA's legendary Group B regulations. That meant that it competed with the likes of the Lancia 037, Ford RS200 and Ferrari 288 GTO – beating them all in the World Rally Championship one after another – but also had to be built in limited quantities and sold to the public. And so Audi and its nascent Quattro GmbH skunkworks division built 214 road-going examples of the Sport Quattro, and this could very well be the most immaculate example in existence. It was previously owned by noted collector Yoshikuni Okamoto of Kobe, Japan, and with barely more than 5,000 miles on the odometer, recently underwent an exhaustive service at Audi of Fairfield, CT – one of the company's largest dealerships – and though the Sport Quattro was never offered for sale in the US, this one is now fully registered for use on American roads and comes in impeccable condition despite its 30 years of age. The gavel drops during the RM Auctions event at the Arizona Biltmore on January 15-16, 2015. Even the low end of the pre-auction estimate is nearly double the $184,860 which Sports Car Market reports Bonhams sold an '85 Audi Sport Quattro in September 2013.
