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.

2014 Audi A6, A7 and Q5 TDI diesel models get pricing and fuel economy figures [w/videos]

Last year, Audi announced that it was expanding its lineup of TDI models for 2014 with the Q5, A6 and A7 joining the diesel-burning Q7 and A8 L models already in existence. The Q7 TDI has been out for a few years now and we recently drove the A8 L TDI, but now Audi has released the pricing, performance and fuel economy details for the 2014 Q5 TDI, A6 TDI and the ever-stylish A7 TDI. Down the road, Audi has also promised a TDI version of the next-generation A3 that will debut for 2014.
Until the new A3 TDI shows up, the Q5 will be the most affordable diesel model in Audi's lineup, with a starting price of $46,500 to go with fuel economy estimates of 24 mpg city and 31 mpg highway. The closely related A6 and A7 will get identical fuel economy numbers of 24 city and 38 highway in diesel form, with the A6 TDI starting at $57,500 and the A7 TDI starting at $66,900. In the three new TDI applications, Audi's 3.0-liter V6 produces 240 horsepower and 428 pound-feet of torque, and all models are paired with an eight-speed automatic transmission. Scroll down for videos (stock running footage) and more information on the Q5 TDI, A6 TDI and A7 TDI, all of which go on sale in late summer.

For Audi, Quattro name means something for hydrogen cars, too

Forget Dueling Banjos. Audi is proposing "Dueling Motors" for its Audi A7 Sportback H-Tron Quattro concept vehicle. All in the name of appropriate pickup, of course. The German automaker, which showed off the concept sedan at the Los Angeles Auto Show last month, is pairing a plug-in electric motor with a hydrogen fuel cell powertrain. Each motor powers two wheels, maintaining the Quattro's all-wheel-drive pedigree. The car's 8.8-kWh lithium-ion battery can drive the car as far as 31 miles on battery-power alone. After that, the water-vapor-spewing fuel-cell engine kicks in. Audi executive Ulrich Hackenberg told Automotive News Europe that the unusual set-up is necessary because the hydrogen fuel cell powertrain alone would only power two wheels while providing an insufficient 136 horsepower. Not exactly sport-sedan material, especially for a car that weighs about 4,300 pounds, even if it is a zero-emission ride. Combined, the two engines give the sedan 231 horsepower as well as a combined single-charge/full-tank range of almost 350 miles. What it all means is that the A7 can go from 0 to 60 miles per hour in less than eight seconds and has a top speed of about 112 miles per hour, and can still dash through the snow.
