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.

2014 Audi RS Q3 breaks out ahead of Geneva reveal

Ahead of its big reveal next month at the 2013 Geneva Motor Show, Audi has released a handful of images and plenty of details for the all-new RS Q3. As the first-ever crossover from the marque with RS branding, this will be the fourth RS model to go on sale this year after the RS5 Cabriolet, RS6 Avant and the RS7, and while UK and Germany sales have been confirmed, there is no word as to whether we can expect this high-performance CUV to be available in the North America.
Sharing its 2.5-liter turbocharged and direct-injected five-cylinder engine with models like the TT RS and the RS3 Sportback, the 2014 Audi RS Q3 should deliver on performance, as it pumps out 310 horsepower and 309 pound-feet of torque (peak torque starting at just 1,500 rpm and running up through 5,200 rpm). This potent engine is paired to Audi's seven-speed S tronic transmission and Quattro all-wheel drive. Despite its small stature, the RS Q3 still tips the scales at just over 3,800 pounds. Even so, performance figures are still impressive with a limited top of 155 miles per hour and a stated 0-62 mph time of 5.5 seconds. The RS Q3 also gets a sport suspension that has been lowered by 25 millimeters, launch control and weight-saving front rotors with a wave-cut and cross-drilled design gripped by massive eight-piston calipers.
Looking almost identical to what we saw last year in concept form in China, the 2014 RS Q3 looks just as sporty as its spec sheet suggests that it is. Up front, the fascia gets massive air intakes with silver vertical accents and, like other recent RS models, the Quattro emblem is written across the lower air intake. The silver accent motif also continues on the grille surround, mirror caps, roof rails and rear diffuser trim, and the oval exhaust outlet is also an identifying feature of Audi's RS cars.

Audi celebrates original RS with RS4 Avant Nogaro selection

It's been 20 years since Audi unveiled the RS2 Avant, the progenitor of an entire range of ridiculously fun luxury cars, including the RS3, three generations of the RS4, three generations of RS6, the RS5, and new RS7 and RS Q3. In honor of the anniversary, Audi is paying tribute to the Porsche-fettled wagon by releasing a special edition of its modern-day counterpart, the RS4 Avant.
Called the RS4 Nogaro selection, it sports vibrant Nogaro Blue paint, which is similar to the RS2's signature color. The twin oval exhaust, window frames, and grille surround are finished in gloss black, while the roof rails are matte black. 20-inch wheels in a V-spoke pattern are the RS4 Nogaro's final exterior tell.
In the cabin, Nogaro Blue Alcantara suede accents are optional on the door panels and seat inners (black suede is also available), while Valcona leather comes standard on the seat outers. The steering wheel, meanwhile, features Nogaro Blue contrast stitching and is wrapped in black leather. Blue threads in the carbon fiber trim and a special-edition shifter round out the interior work on this special edition RS4.
