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.

VW Golf R 400 reportedly green-lit (again)

After speaking to Volkswagen powertrain boss Dr. Heinz-Jakob Neusser at the 2015 New York International Auto Show, we uncovered that the Volkswagen Golf R 400 would be sold in the United States... if it ever made it to production at all, that is. That prerequisite looks like it's about to be fulfilled, as the same good doctor that said the super-powered GTI would come to the US has confirmed to Car that development is currently underway. This follows up on reports from late 2014 that the 400-horsepower car would make production. "We have the Golf more sporty than ever before, since we soon will have the Golf R 400 – we will do this car," Neusser told Car. "We are in fact in development of it right now." That is, we think you'll agree, splendid news. Of course, it also begs the question of when the new car will arrive. According to Car, it'll be just "a few short months," indicating that the Frankfurt Motor Show will likely host the Golf R 400's debut later this year. Whether that proves correct, though, likely won't be clear until later this summer.

Everyone but VW and Tesla has recalled their Takata airbags

Takata's massive airbag inflator recall affected over 32 million vehicles from 11 automakers in the US, but two companies buying the supplier's parts haven't been affected so far: Volkswagen and Tesla. There are 887,055 VWs and 184,926 Teslas using Takata's inflators with ammonium-nitrate propellant, a new accounting shows, according to Automotive News. That doesn't necessarily mean the models need to be recalled. These figures came from a report that Takata prepared for the National Highway Traffic Safety Administration, which listed all of the vehicles it supplied with ammonium nitrate-fueled inflators. The substance is believed to be linked with the components' rupturing, along with manufacturing defects and humidity. "We're not asking because we've got reports of problems; we just need to figure out what the universe is," NHTSA spokesman Gordon Trowbridge said to Automotive News. Takata reportedly told Tesla that the inflators in its EVs are not affected with these problems, and VW is investigating a case in June where a side airbag allegedly burst in a 2015 Tiguan, Automotive News reports. The government is also still researching the precise cause of the parts' ruptures. If the investigation finds ammonium nitrate to be a factor, the vehicles could need recalled. During a Congressional hearing Takata vice president Kevin Kennedy admitted that ammonium nitrate could be among the factors of the ruptures, but the company has continued to use the chemical in its inflators. Takata is now working to transition to a different propellant. Related Video:
