Audi pushing DOT to allow its sequential LED turn signals [w/videos]

Still in the process of trying to get its trick LED Matrix Beam headlights legalized in the US, Audi is now trying to get its front and rear sequential LED turn signals approved by the National Highway Traffic Safety Administration. Just like its auto-dimming headlights, the sequentially illuminating turn signals don't meet NHTSA's Federal Motor Vehicle Safety Standard 108.
The problem, according to Automotive News, is that the individual lighting elements are too small to meet current US safety regulations. The rule states that each lamp should be 22 square centimeters (8.6 square inches) and the whole lighted combined area must be 50 square centimeters (19.6 square inches). In the individual sequence, Audi's lights are much smaller than that. As for the Ford Mustang, which has had sequential turn signals since 2010, this system is legal since the first lens is large enough to meet the required size, so the other two lights really aren't even necessary.
It sounds like it could be some time before we see these turn signals on Audis in the US, which is a shame because in addition to their styling bebefuts, we think they're more effective at signaling the vehicle's intended direction of travel, and they do a better job of grabbing the eye. Scroll down to watch a pair of videos showing the headlights in action on the redesigned A8/S8 as well as the recently updated R8.

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:

Audi stealthily tests RS4 Avant

With S3s, R8s and RS7s aplenty, Audi offers no shortage of performance models in North America. But one of our favorites is always kept just out of arm's reach. That of course is the RS4 Avant, and here we see Audi Quattro GmbH testing the latest version. Though it may look like a plain old S4 – and even wear S4 badges – the wider fenders and bigger wheels suggest that this is in fact a prototype for the upcoming RS4 Avant. For those unfamiliar, that nameplate connotes the best of all worlds within the A4 range: maximum power, maximum traction, and maximum luggage space. All the ingredients, in short, to make us wonder why anyone would rather drive a crossover. After the first-gen RS4 employed a twin-turbo V6, the subsequent two generations went with a 4.2-liter V8. This model, however, could adopt an electric turbocharger setup to give it all the power it needs (and then some) with a new form of hybrid setup that will soon be spreading across the industry. The bigger question on our mind, of course, is whether the new performance wagon will make the transatlantic voyage to North American showrooms. We're holding out hope that Ingolstadt may make a real run down American roads at the likes of the Mercedes-AMG C63 and BMW M3. Whether it brings the wagon body-style along with it is another matter entirely, but we can always dream. Related Video:
