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 teases Frankfurt reveal... is it the A8?

Audi has already rumored to have plans to reveal a 650-horsepower Sport Quattro Concept at the 2013 Frankfurt Motor Show in September, but it also seems that we'll be getting our first look at the 2015 Audi A8 as well. Based on a panned-out shot of a teaser video, we can clearly see that this is a new sedan model, so it makes sense that is the updated A8 since we've already seen recent spy shots of that car that seemed to be almost complete.
In the short video, all that we can definitely see is the Audi logo in the grille, a five-spoke wheel with cross-drilled, ceramic disc brakes and a small portion of the front fender that has an almost mirror-like shine. We'll find out for sure in September, but until then, check out the teaser video posted below.

Audi A7 getting nip and tuck

It's been less than two years since the Audi A7 first went on sale in the US, but European buyers have been able to enjoy the sleek and stylish hatchback for twice as long. As such, Audi is preparing to give its A7 a mild refresh with tweaked exterior styling, but we're also expecting some of the features found in the all-new 2015 Audi A8 to possibly trickle down to the A7.
From what we can tell in these spy shots, the A7 is getting a minor facelift that includes a restyled front fascia and new headlights, which will likely boast Audi's new Matrix LED system. At the rear of the car, similar changes have been made with a fascia that now gets integrated outlets and different taillights that have a Lamborghini-like display.
Not apparent in these images - but still a good bet for production - we'd expect to see the new A7 get some of Audi's updated engines or new driver assist technologies. No definite word as to when we'll be seeing the refreshed A7 in person, but considering how close to production ready as this car seems to be, our bet is on the upcoming Geneva Motor Show.
