Audi Sport Quattro Concept to race into Frankfurt

Audi has pulled the official wraps off its new Sport Quattro Concept, which will be debuted at the 2013 Frankfurt Motor Show. The automaker is understandably keen to draw inspiration from its classic Quattro line of automobiles, specifically the original Ur-Quattro from 1980 and the short-wheelbase Sport Quattro that took part in rally racing and set a record at the Pikes Peak Hill Climb in 1987. A massive dose of modernity comes courtesy of its 700-horsepower plug-in hybrid powertrain.
There is a clear link in the styling of the Sport Quattro Concept to Quattro coupes of the past, from the large flat surfaces that make up its C pillars to the blisters over the fenders and the basic headlamp shape (equipped as they are with Audi's Matrix LED technology). Pay special attention to the car's grille, which introduces a slightly new design language that is expected to be seen in the next generation of Audi's mainstream production models.
The interior of the Sport Quattro Concept is a refreshing departure from Audi's admittedly attractive and useable design, with sharp lines and lots of visible carbon fiber. There are seats for four occupants inside, along with a comparatively generous cargo area measuring 10.59 cubic feet.

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 builds 3-millionth A3

About a month after Volkswagen celebrated building its 30-millionth example of the Golf, Audi has announced that it has produced three million versions of its small hatchback, the closely related Audi A3. Probably more surprising than the fact that the A3 has moved in such big numbers since its global debut in 1996 is the fact that it has done so with relatively little support in the US, seeing marginal sales in the States since 2005.
The three-millionth A3 was a Sportback TDI model, but the lineup has grown this year to include a new sedan and S3 model, and the hybrid A3 E-tron is on the way. With these new models - especially the sedan in the US - we expect the A3 to continue to be a popular entrant in the premium small segment. Scroll down for Audi's official press release.
