Audi prepping minor refresh for S6

Audi is well underway with testing for all of the refreshed versions of its A6-based sedan. We've already shown you shots of the Euro-spec A6 Allroad (which will wear some of its styling with our US-spec A6 sedan), and now we have some shots of a car that will actually arrive in the United States - the S6.
Like the Allroad, this will be quite a modest refresh, with tweaks to the headlights and taillights, as well as some slightly revised front and rear fascias. The headlights should get a new LED DRL pattern, although we doubt the changes will be much more drastic than that.
As with the Allroad, it seems likely that Audi will make a few very small changes to the interior, while the MMI infotainment system should also see an update. Changes under the hood, though, are more difficult to guess. That said, minor changes could be in store, but don't expect a dramatic increase in power or performance.

VW stock plummets as Euro markets open

The fallout from Volkswagen's installation of an emissions "defeat device" on nearly 500,000 diesel-fueled models in the US is already hitting the automaker hard on the German stock exchange. At one point, the share price plummeted 23 percent to erase the equivalent of $17.6 billion in value. Things eventually bounced back slightly to a still severe 19.23 percent loss, according to Bloomberg as of this writing. The scandal couldn't come at a worse time for chairman Martin Winterkorn. The VW supervisory board takes up the issue of renewing his contract on September 25, Bloomberg reports. If things get bad enough, the door could be open for a new boss to step in. Dealers in the US might start feeling the pain from this, as well. Affected 2015 VWs that are still at showrooms are now under a stop sale. Until the issue is straightened out, the Environmental Protection Agency isn't certifying the company's 2016 diesel models with the 2.0 TDI, either. The diesel emissions problem was first discovered by research from West Virginia University and the International Council on Clean Transportation. In some cases, the engines can produce 40 times more nitrogen oxides than allowed. The automaker could be on the hook for $18 billion in fines for the breach, but the actual figure is expected to be lower. In response, Winterkorn has issued a public apology and ordered an independent investigation into what happened. The EPA and California Air Resources Board have also been looking into the situation. This could become an international problem, though. According to The Detroit News, European authorities might begin similar inquires to check the automaker's diesel emissions there.

New info on how VW, Porsche, Audi V6 TDI engine cheat works

The German newspaper Bild am Sonntag is reporting that US investigators have found three pieces of software that work in concert to turn off the emissions control equipment in certain diesel models after a set period of time. The engine in question, the 3.0-liter TDI turbodiesel, was found in certain Volkswagen Touareg, Audi Q7, and Porsche Cayenne models – the sale of which was suspended in the US late last year. Since most emissions compliance testing takes around 20 minutes, the software in the three VW Group models shuts off the emissions control equipment after 22 minutes, a straightforward end run around the testing. Remember that the 3.0-liter TDI engines aren't included in the big buyback and recall program announced for the smaller 2.0-liter, four-cylinder TDI engines. The 3.0-liter engines will likely get their own program, but we don't know when to expect it or exactly what it will look like. Last month, California rejected a proposed fix for the larger TDI engines, and VW went back to the drawing board. Since the company is unlikely to create two fixes, one for California and one for the rest of the nation, the company can't really proceed until they figure out a solution California will accept. The EPA hasn't officially commented on the report, and we don't know how Bild am Sonntag came across the information, but we'll be closely watching what emerges after this report. Related Video:
