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.

2013 Volkswagen Jetta Hybrid

More Fun Than A Prius, Less Sensible Than A TDI
Let's have some fun, and do some math. We're talking pretty rudimentary stuff, multiplication and division, to figure out if the upcoming Volkswagen Jetta Hybrid can make a baseline case for itself against two very strong competitors in this segment. The competitors in question, at least for now, are two more Jettas: the diesel-drinking TDI and the fit-for-the-masses SE with VW's long-serving 2.5-liter engine.
To keep the equations clean and simple (hey, we're writers), we'll calculate based on the most flattering EPA miles per gallon stat from highway driving for all cars, assume a healthy 20,000 miles driven per year, and factor in today's average cost for the respective fuels these three require: diesel (TDI), regular (SE) and premium (Hybrid). We'll also start with the base prices for all models.

VW close to decision on selling Bugatti to Rimac

FRANKFURT — Electric hypercar maker Rimac Automobili and Volkswagen's supercar brand Bugatti are a good technological fit, Porsche's CEO told German weekly Automobilwoche, fueling hopes that a deal between the two could happen soon. British automotive magazine Car last year reported that Volkswagen was on the verge of selling Bugatti to Rimac Automobili, citing sources. In exchange, Porsche, also owned by Volkswagen, would raise the 15.5% stake it owns in Rimac, founded by Croatian entrepreneur Mate Rimac, Car said. "At the moment there are intense deliberations on how Bugatti can be developed in the best possible way. Rimac could play a role here because the brands are a good technological fit," Porsche CEO Oliver Blume said. "There are various scenarios with different structures. I believe that the issue will be decided by the group in the first half of the year," said Blume, who also sits on the management board of parent Volkswagen. Rimac has developed an electric supercar platform, which he supplies to other carmakers, including Pininfarina. Blume also confirmed higher savings targets for Porsche, saying the carmaker plans to support results by 10 billion euros ($12.1 billion) of cost cuts by 2025, up from 6 billion previously.
