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.

Audi inaugurates new R8 production line at Neckarsulm

Of all the factories which the Volkswagen Group operates around the world, the Audi plant in Neckarsulm may not be the very largest, but it is among the most diversified. That's where Audi builds versions of the A4, A5, A6, A8 and Q7 lines. It's also been home to the R8, but now the German automaker has moved supercar production to a new facility just a few miles down the road.
Back in August, Audi stopped production of the R8 at its main Neckarsulm site and moved it to the new Böllinger Höfe site in Heilbronn, restarting production just three weeks later. The new assembly line brings together various workshops that had been scattered about the Neckarsulm complex under one roof, and will surely make production of the next-generation R8 that much smoother.
The Böllinger Höfe facility is about a quarter the size of the main Neckarsulm plant, and will also house a small-scale production line - similar, we gather, to what Audi subsidiary Lamborghini recently built in Sant'Agata Bolognese - and a massive, state-of-the-art logistics center with capable of handling 4,500 containers each day.

Audi celebrates diesel milestone with triple-charged RS5 TDI concept

Diesels are typically slower than their gasoline counterparts, but leave it to Audi to turn that notion on its head. After dominating Le Mans and the international endurance racing scene under diesel power for the better part of a decade, the German automaker toyed with the idea of an oil-burning R8 for the road and ultimately made its first performance crossover a diesel. It's made the letters TDI a battle cry, and now it's yelling even louder with the RS5 TDI concept.
Set to be unveiled in a couple of days at the Leipzig Auto Show to celebrate 25 years of the TDI engine, the concept ditches the gasoline-burning 4.2-liter V8 in the production RS5 in favor of a 3.0-liter V6 twin-turbo-diesel with an electric supercharger added on to combat turbo lag. Output comes in at 385 horsepower and 553 pound-feet of torque, which means that while it has 65 fewer horses than the gasoline model, it packs a staggering 236 lb-ft more torque.
The result of the triple-charged madness is a 0-62 time around four seconds flat, trumping the 4.6 seconds for the road-going model. Top speed, of course, is electronically limited to 155 miles per hour, which is a bit of a shame because we bet it'd be a kick to pass a Porsche on the Autobahn in a diesel, now wouldn't it?
