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 builds 5-millionth vehicle with Quattro

Quattro, the trademark name Audi has put on its all-wheel-drive system engineered for passenger vehicles, recently celebrated its five-millionth installation. The driveline has been offered in more than 140 different vehicles since its introduction more than three decades ago.
The all-wheel-drive technology made its world debut at the 1980 International Geneva Motor Show, beneath the floorpan of the Quattro Coupé, a low-volume two-door. It didn't take consumers long to embrace Audi's innovative approach. While most four-wheel-drive systems at that time utilized heavy transfer cases or second cardan shafts, Quattro was virtually tension-free, light, compact and efficient. Most importantly, enthusiasts found it was especially suitable for sports cars.
Today, the automaker offers Quattro on its full line of passenger vehicles and it is unquestionably successful (the technology enjoyed a 43 percent take rate in 2012). On models with transverse-mounted engines (A3 and TT), Audi uses an electronically controlled multi-plate clutch with hydraulic actuator. Under normal conditions, the clutch sends power almost exclusively to the front wheels (if wheel slippage occurs, up to 100 percent of the torque may be sent to the rear). Vehicles with transverse-mounted engines (A4, A5, Q5, etc...) use a self-locking center differential sending 40 percent of the engine torque to the front axle and 60 percent to the rear under normal conditions (it is able to send the majority of the power to the axle with better traction when needed). The highest-performing Quattro systems use torque vectoring to further improve cornering grip and speeds.

Next Audi A7 redesign will include more traditional rear end

A report in Automobile says that Audi is rethinking the design of the next A7. Audi told Car and Driver that owners "have trouble with the radical tail of the A7," so its model-defining rear end will give way to something more traditional. Automobile is light on specifics of the redesign, but the general direction is "a lower, wider, and more expressive shape." The philosophy behind the dimensions and styling is a "C/D shift," meaning Audi wants to give its C-segment hatchback the bearing, gravitas, and visual delight of a D-segment vehicle. That would help the A7 stand out from its in-house competition, and could make for higher transaction prices. Having heard about different design directions from Audi for years without much in the showroom to back it up, we could define what we'd love to see in two words: more Prologue. This is Audi, so you know the next A7 will be packed with tech. We expect an emphasis on touchscreen interfaces, a digital dash cluster a la the TT that moves with the steering column, a HUD with night vision, and an MMI system a few more steps down the evolutionary trail. Engines will see some upgrades like the addition of a plug-in hybrid, the excellent 2.0-liter, turbocharged four-cylinder getting a 74-horsepower e-boost assist to 326 horsepower, the 3.0-liter V6 slated for the S7 rising to 500 hp, and the 4.0-liter V8 in the RS7 pumping out 575 hp.
