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 TT Offroad concept packs 408 hybrid horsepower, yet returns 123 mpg

Audi took the wraps of its TT Offroad Concept at the Beijing Motor Show, after teasing us with sketches earlier this month. "The Audi TT offroad concept provides a glimpse of how we might imagine a new model in the future TT family," says Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development. "It combines the sporty genes of the TT with the strengths of a compact Audi SUV."
The latest in Audi's eTron show cars reminds us an awful lot of the the Audi Allroad Shooting Brake concept that debuted a few months ago at the Detroit Auto Show. In addition to very similar physical appearances, the two share the same plug-in hybrid propulsion systems (the "plug-in" part is a bit misleading, as the concept simply needs to be parked over an inductive pad to take advantage of Audi Wireless Charging technology).
Proving that hybrid power never has to be a compromise, the TT Offroad Concept packs a 292 horsepower turbocharged 2.0-liter four-cylinder under the hood. The combustion engine is assisted by two electric motors (rated at 40 kW at the front and 85 kW at the rear) to provide a total system output of 408 horsepower and nearly 480 pound-feet of torque. With all-wheel drive, the concept hits 60 mph in 5.2 seconds and tops out at 155 mph - while returning a provisional fuel efficiency of 123 miles per gallon equivalent.

Audi Traffic Light Assist helps you hit every green light

Before taking a ride in Audi's impressive Piloted Driving A7, we took a short spin up and down the Las Vegas strip to check out a smaller, but intriguing piece of Audi driver assistance technology called Traffic Light Assist that promises to help drivers make every green light.
Using both live and predictive data beamed into the vehicle's navigation unit via onboard wifi, TLA doesn't need a single camera to tell you when the light is going to change. Local data sources provide information about traffic light patters, and the in car system uses that data and the motion of the car to predict exactly how long it'll be until the green light goes red.
In practice, the system shows a traffic light icon in the central display (a head-up display would be a nice option), along with a countdown timer that reads the number of seconds before a light changes from red to green. Additionally, the system corrects (nearly instantly in our demo) for changing lanes and resultant changing signals; changing a straight-through traffic lane to a left-turn lane and signal, for instance.
