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.

KTM X-Bow to get Audi TT-RS five-cylinder turbo

The Audi TT-RS continues to occupy a warm spot in my personal top five list of cars thanks in no small part to the lusty turbocharged 2.5-liter five cylinder under the hood. With 360 horsepower and 343 pound-feet of torque in stock configuration, the engine is a shining star of internal combustion. And now it's headed to one of our favorite vehicles. EVO reports KTM is planning to plop the turbo 2.5 from the TT-RS into the upcoming X-Bow. That ruckus you hear? It's a choir of angels singing "Halleluiah." While speaking at the Geneva Motor Show, KTM CEO Stefan Pierer said the engine is good for up to 480 horsepower.
Pierer went on to say that the company is already testing prototypes and that we may very well see the engine show up in some races next year. What's more, the company's engineers are playing with dual-clutch transmissions, too. Since KTM is already testing the turbo 2.5 on the track, it's only a matter of time before customers will be able to get their grubby mitts on a street-legal version.

Audi A8 and S8 get another video tease

If there was any doubt before about which car(s) Audi recently teased in a video, now we know for sure. Audi has released another teaser video that confirms we'll at least be seeing the 2015 Audi S8 (and very likely the A8 as well) in the near future, but the big surprise is just how soon we'll see the new flagship sedan. We originally expected to see the sedan receive its official debut at the Frankfurt Motor Show, but now Audi says that the car will be presented about three weeks before the event on August 21.
How do we know this is the S8? Well, aside from it obviously being a large sedan, the true tell that this is its A8/S8 is the front license plate, which clearly shows "S8" on it - we've been doing this long enough to know that Audi's promotional license plates have the model designation in the plate number. As for other details, Audi's trick Matrix headlights shine through the thin veil in what should be the crown jewel of the sedan's new face. There's a little more than a week to go until the car is unveiled, but for now, check out the video below.
