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.

2015 Audi S3 Sedan

For the last few years, Audi has been publicly toying with building a successor to its Ur-Quattro, a model still glowing in a gritty patina of motorsports glory decades after it left the scene. If anything, the rally car's halo has burned brighter as Audi has matured into a world luxury superpower. Since 2010, the German automaker has shown two different concept cars that attempted to re-bottle the legend's lightning, and it's still trying to figure out whether to market a production model. Despite that conundrum (and not to take anything away from the seminal Ur-Quattro), it's easy to argue that there are two other cars much more important to Audi's rise from its '80s ashes: the original TT and the B5-generation A4 and its high-performance variants.
The TT thrust Audi into the vanguard of automotive styling while firmly establishing the Volkswagen Group as masters of platform development (the same basic architecture and powertrain guts were employed in a dizzying array of models, from the Golf, Jetta and New Beetle to a number of Škoda products). This unprecedented, flexible building-block approach to new model development has since become the standard of the industry.
In the case of its B5 cars, the A4, S4 and RS4 put Audi back on the radar of rival German automakers, and more importantly, they grew the Four Rings' sales by leaps and bounds while reminding the world that all-wheel drive needn't only benefit hardcore performance cars and utility vehicles. Fast-forward to today, and the A4 has established itself as the bedrock of Audi's lineup, but it's also grown over its four generations to become substantially larger, heavier and costlier than the model that debuted back in 1996 America. That's created a vacuum at the bottom of the range that the company has inadequately addressed - until now.

Audi RS7 prototype is world's sportiest self-driving car [w/video]

Audi may not be the only automaker out there toying with self-driving automobile technology, but it is arguably the fastest of them. A few years back, it raced unleashed a driverless TTS on the Bonneville Salt Flats, then sent it up Pikes Peak and around Thunderhill. But now it's taking things a step further with the vehicle you see here.
This RS7 Sportback has been fitted with steering, brakes, throttle and transmission hooked up to a computer system that combines GPS, high-frequency radio signals and 3D imaging camera to drive the vehicle autonomously not just in slow-paced, stop-and-go traffic, but around the track at the same pace a professional racing driver would push it: full throttle on the straights, full braking before the corner and 1.1-g of cornering force.
As promised, Audi plans to unleash the self-driving RS7 - which it calls "the sportiest piloted driving car in the world" - at Hockenheim next weekend prior to the DTM season finale, where it is anticipated to pull a 2:10 lap time. The next stage will be to set it lose on the Nürburgring Nordschleife, all 154 turns and 13 miles of it, which ought to pose a heck of a challenge to the engineers from Ingolstadt. In the meantime you can scope it out in the high-res image gallery above and the second teaser video below.
