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 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.

Audi S5 spied

We only recently saw the next-gen Audi A5 testing for the first time with its sleeker design covered in camouflage. Now, here's a well-concealed glimpse at of the higher-performance S5 for comparison against the standard coupe. With so much swirling camouflage picking out the differences between the two models isn't easy, but there are a few tweaks to notice. The intakes on the front fascia are just a little bigger, hinting at the increase in power. The brakes also appear to be larger, especially when comparing them at the rear. Of course, the most obvious changes are the dual exhausts poking out each corner of the speculative S5. While more power is assured for the S5 over the A5, the exact powerplant isn't officially known yet. Rumors suggest Audi using a tuned version of the supercharged 3.0-liter V6 making between 340 horsepower and 350 hp, at least for the S4. The switch to the MLB Evo platform means less weight to haul around no matter what's under the hood, though. The next-gen A4 should provide some more hints about the future of the lineup when it launches at the Frankfurt Motor Show in September, and the coupes are expected to join the lineup later.
