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.

Audi sees room for TT family, including possible crossover and superlight models

With the third-generation Audi TT slated for a debut at the 2014 Geneva Motor Show in just a few weeks time, we've received some interesting news out of the United Kingdom. Speaking to the crew at Top Gear, Chief Engineer Ulrich Hackenberg made some interesting statements about the next TT, noting that he likes the idea of a production Allroad Shooting Brake.
"I can imagine the TT has much more potential than we have used up to now. That's why we did this Allroad [Shooting Brake] Concept. The trend is to smaller crossovers. So for example you do a crossover TT. It would have a big group of fans," Hackenberg told TG.
That makes it almost sound like Audi is trying to expand one popular, fashion-forward model into a wildly different niche, like Mini did moving from Hardtop to Countryman (or perhaps more appropriately, the Paceman). We'll reserve judgement, if only because the Allroad Shooting Brake was one of the more popular concepts at the Detroit Auto Show, making our Editors' Choice list.

Audi looks at the future of transportation for Ender's Game film

The forthcoming science-fiction movie Ender's Game, starring Harrison Ford and Ben Kingsley, takes place in a high-tech world. So if movie-watchers are to be fully immersed in the story, every detail counts. That's why the computer-generated special-effects company assigned to the movie, Digital Domain, enlisted the help of Audi to design a future car that would fit seamlessly in the film's world - part of its $17.2-million investment in the movie.
Audi went all out, with Head of Audi Exterior Studio 1 Frank Rimili and designer Björn Wehrli assigned to the Audi Fleet Shuttle Quattro's design, which is so thorough and cohesive that we wouldn't be surprised to see cars like it on the road three-quarters of a century down the line. Rimili doubts that, but is "absolutely sure" Audi will still be around in 2088.
Watch the making-of video below to see all of the work that went into designing a car that will never see the light of day - in the real world, that is. If you're a fan of science fiction or the novel on which the movie is based, head on over to a theater to watch Ender's Game, which opens on Friday.
