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.

Audi reveals new beefed-up A8 L Security

Audi claims is the lightest armored vehicle of its kind.
If there were ever a sedan that deserved the descriptor of "luxury," surely it's the Audi A8. Particularly in long-wheelbase form. But for many of Audi's wealthy customers around the world - namely those in developing markets - there can be no greater luxury than security. And for just those customers, Audi has announced the new A8 L Security.

Audi chooses A3 as its Super Bowl darling

With Super Bowl XLVIII less than two months away, we're sure to hear plenty of news about automakers and their various plans for in-game commercials. Audi has announced that it will return for its seventh year of Super Bowl advertising, but few details were provided about the spot other than the fact that it will focus on the all-new 2015 A3.
The 60-second ad will air during the third quarter of the game, and while Audi did not say how much it is spending on the spot, Ad Age says that a 30-second commercial will average around $4 million for next year's Big Game. Last year, Audi's choose-your-own-adventure "Prom" commercial was the second favorite video in our unofficial poll of readers, but the competition should heat up even more this year with General Motors returning to Super Bowl advertising after taking a year off and Jaguar preparing its first-ever Super Bowl ad to introduce the F-Type Coupe.
