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 reportedly will cut costs by $12B to fund electric-car push

BERLIN - Audi aims to cut costs by 10 billion euros ($12 billion) by 2022 to fund a shift to electric cars as it seeks to move on after the emissions scandal, sources close to the carmaker said. Audi, Volkswagen's main profit driver, plans to bring five new all-electric models to market in coming years, starting with the E-Tron sport-utility vehicle (SUV) to be assembled from 2018 in Brussels. Despite run-up costs for its electric-car program, the luxury automaker wants to keep its operating profit margin at 8 percent a year at least, two sources close to Audi said. Its profit margin in the first half of this year was 8.9 percent. The bulk of the $12 billion cost savings would come from cutting research and development costs, the sources said. A spokesman at Audi's headquarters in Ingolstadt, Germany, declined comment. German business daily Handelsblatt reported the cost-savings target and profitability plans earlier on Sunday. Audi also aims to free up money for investments in zero-emission technology by developing a new production platform with Porsche, allowing both VW premium brands to save money by sharing components and modules. Audi is grappling with car recalls, prosecutor investigations, and persistent criticism from unions and managers over the diesel emissions scandal and its post-dieselgate strategy. Sources told Reuters on Friday that four of the brand's seven top executives are earmarked for dismissal in the near future. On Sunday, sources said the dismissals were discussed by supervisory board members last Thursday but a formal decision has yet to be taken.

First official Audi R8 photo leaks

The next-gen Audi R8 makes its grand debut in a just a few days at the 2015 Geneva Motor Show. However, leaks aren't uncommon for such a highly anticipated model, and it appears that the first official shot of the future supercar is now online. Autoblog en Espanol claims this is the first leaked factory photo showing the new Audi R8 completely undisguised. The single image depicts the supercar from the front, and it looks a lot like both Audi's own official teaser and the previous blurry image from Instagram. Based on this picture, the German designers thickened the outline around the grille at the front and added vertical slats at each corner. They also removed the gentle curve in the headlights in favor of a completely angular look. While the side blades were one of the major styling features of the original, their appearance has been toned down by removing the vertical, contrasting strip running up the body. Though the exterior design seems to evolve the R8 slightly, there are some big changes for the powertrain. Audi is ditching the V8 for the latest model and opting for two tunes of the 5.2-liter V10. The standard version gets 540 horsepower, and the Plus pushes output up to 610 hp. The top trim can reportedly hit 60 miles per hour in 3.2 seconds and reach a top speed of 205 mph. Although, there are already the rumors of other variants, including a turbo V6, coming later. Related Video:
