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.

New Audi A5 to debut in Ingolstadt on June 2

Audi will introduce the second-generation A5 during a late-night lightshow at its Ingolstadt, Germany, museum on June 2. In the announcement, the company only called out the standard model, but a new S5 coupe is probably not too far behind. Details on the next A5 have been scarce, and spy shots haven't revealed much. Our most recent images come from June of last year and show a vehicle that more or less follows the current A5's theme – a two-door A4 with a few small visual tweaks to distinguish it from the sedan, including a wider stance. Expect an interior treatment very similar to the A4's as well. The new coupe's mechanicals should mirror those of the four-door as well. The A5 will likely stick with a 2.0-liter, turbocharged four-cylinder (the A4's currently makes 252 hp) and ditch the current car's eight-speed automatic transmission for a new seven-speed dual-clutch. Unlike the sedan, the coupe is likely to continue offering a six-speed manual, as it is positioned as a sportier option even if it shares the A4's platform. Front-wheel drive will be standard, while Quattro all-wheel drive will be the one to buy. The S5 should definitely offer a manual again, along with the S4's 354-hp turbo 3.0-liter V6 and standard all-wheel drive. A seven-speed dual-clutch will be an optional extra, again, just like on the S4. Timing of the new A5's arrival appears to have shifted. A leaked product roadmap originally called out April 2016 for the A5 and S5 hardtop and May 2016 for the Cabriolet versions. Based on the June 2 debut, it looks like Audi pushed those dates back, so we'd expect the new convertibles to make their debut sometime in July. The new A5 is pegged to arrive as a 2018 model. We'll have all the details on the new A5 Coupe when it debuts early next month. Related Video:

Audi is working on a suspension that gets power from bumpy roads

Regenerative brakes aren't new. They're on virtually every hybrid and EV, and they're even starting to pop up on traditional gas-powered cars, like with the i-ELOOP-equipped Mazda6. But even with these systems, cars can get more efficient, and Audi thinks it found yet another source of wasted energy. The source? The suspension. The idea is to turn the kinetic energy that goes into the dampers into usable energy instead of as waste heat. Audi isn't the first auto company to come up with regenerative suspension – nearly three years ago, ZF introduced its GenShock technology, which used a valve attached to traditional, oil-filled hydraulic shocks to recapture kinetic energy from movement caused by bumps in the road. Audi's prototype technology, which it calls eROT, replaces traditional dampers with horizontally oriented electromechanical rotary dampers. eROT is apparently short for electromechanical rotary damper. Neat. In testing, eROT recovered an average of 100 to 150 watts on a typical German road, three watts from a fresh piece of pavement, and 613 watts on a rough stretch of tarmac (wattage is calculated as power over time, so this is actually the rate at which the system harvests energy). The dampers channel that energy to a tiny, 0.5-kWh, 48-volt battery. The prototype is claimed to cut CO2 emissions by three grams per kilometer (4.8 grams per mile), while the company believes a future production version could save up to 0.7 liters of fuel per 100 kilometers of driving. Converting the savings to American miles per gallon isn't easy, so we'll use a practical example. In the US, the Q7's supercharged 3.0-liter V6 returns a combined rating of 21 miles per gallon, which works out to 11.2 liters per 100 kilometers. Apply eROT's 0.7L/100km savings, and the Q7's economy would improve to 10.5L/100km, or 22.4 mpg, a 1.4-mpg improvement. That's not huge, but because math, 0.7L/100km is more dramatic on a more fuel efficient vehicle – taking an A3's 27-mpg combined rating and adding eROT would drive efficiency up 2.4 mpg, for example. There are a few other big benefits beyond fuel and emissions savings – Audi claims eROT provides a more comfortable ride than traditional active suspensions, because engineers can tune the compression and rebound strokes independently of each other. Beyond that, the horizontally oriented rear suspension geometry means more cargo space, since the dampers don't poke up into the cabin like they normally do.
