Volkswagen plans expansion, tech center in Chattanooga

Volkswagen is expanding its growing Chattanooga, TN, factory by even more than the original plans after winning the local government's approval. The German automaker announced its intention last year to invest $900 million to add 538,000 square feet of floor space to the plant, which would add 2,000 new jobs. The company just went back to the city for permission to increase the expansion by a further 130,153 square feet for an even larger body shop. The extra construction is estimated to cost around $18 million. VW spokesperson Catharina Mette described the decision as "a cost-saving option," to Autoblog. "Taking this action now saves money while giving us flexibility as we integrate the MQB platform in the future," she said. By the end of 2016, the Chattanooga plant will begin production of VW's forthcoming crossover, which should look similar to the Cross Coupe GTE concept. VW has further plans for the research, development, and planning center near the factory. According to the Chattanooga Times Free Press, some of the designers and engineers will start work at a temporary facility there next week. A permanent location will open in 2017 with a test track and space to perform crash evaluations. The engineering center is meant to speed up the rate of vehicle development to bring models to the North American market more quickly."This will be the central entity in all the US, and hopefully all of North America," Matthias Erb, who oversees the center, said to the newspaper.

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.
