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 confirms all-electric SUV on the way

The electric crossover segment might become a hot market in just a few years. In addition to the rumors of an electric Jaguar F-Pace and obviously the Tesla Model X, Audi is now confirming an EV "sports activity vehicle" for early 2018. The Germany luxury brand even showed off a rendering (pictured above) of it during the company's annual press conference. Audi technical development boss Dr. Ulrich Hackenberg made the announcement during his portion of the conference but largely avoided hard details. What he said was tantalizing, though. The still un-named model was claimed to offer over 311 miles of driving range and ride on the brand's upcoming MLB 2 platform. Although, Auto Express suggests that it could be called the Q6 E-Tron. Dr. Hackenberg also promised a "new, very attractive design, which we are developing especially for the E-Tron range and for battery-electric vehicles." The rendering showcased a fairly squat crossover design with bold fender flares dominating the styling in profile. The images also suggested almost coupe-like proportions. Thankfully, the wait for more details about the model might not be too long. Dr. Hackenberg told Auto Express that Audi would have a presentation soon about the new model. He also hinted at a little of its tech by suggesting next-gen batteries offering 50 amp-hours and 90 kWh could be enough for sufficient range even in such a large model. With recent unveilings like the R8 E-Tron and Q7 E-Tron, Audi is rapidly moving towards offering more plugins and electric models. With this latest announcement, that expansion only appears to be accelerating. Prof. Dr.-Ing. Ulrich Hackenberg, Member of the Board of Management at AUDI AG for Technical Development Speech to the Annual Press Conference 2015 Ladies and Gentlemen, 2014 was the year of technical milestones, tests and records. Think of the sportiest piloted car in the world, the Audi RS 7 concept, which lapped the Hockenheimring racetrack extremely dynamically without a driver – at up to 240 km/h. Another mega-success was our 13th victory in the world's most important endurance race. The Audi R18 e-tron quattro with diesel-hybrid drive triumphed in the 24 Hours of Le Mans. 2014 – that was also 25 years of TDI technology. As strong evidence of the future viability of combustion engines, we showed the Audi RS 5 TDI concept – the fastest diesel ever timed on the Hockenheimring.

Lexus LC 500 dominates 2016 EyesOn Design Awards

The Lexus LC 500 captured top honors for the best-designed production car and the best interior at the 10th annual EyesOn Design awards at the Detroit Auto Show. The awards are handed out by the Detroit Institute of Ophthalmology. The Buick Avista won the concept car category, just as its four-door predecessor, the Avenir, did last year. Other winners this year included the Chrysler Pacifica, which won for the best-designed production "truck" (as crossovers and minivans are sometimes categorized), and the Audi H-Tron Quattro, which won for the best concept truck. The Acura Precision concept was also recognized for its "innovative use of color, graphics, and materials." And the new Volvo S90 was singled out for its human-machine interface. The panel of jurists this year included designers from an array of automakers and art schools. Several past honorees for the organization's LifeTime Design Achievement Award participated in the voting, including GM's Wayne Cherry, BMW DesignworksUSA founder Chuck Pelly, Hyundai's Peter Schreyer, and Jack Telnack (formerly of Ford). Telnack also served on the select panel of chief judges this year, alongside Chris Chapman from Hyundai, Dave Marek from Acura, and Stewart Reed from the Art Center College of Design. Lexus Takes 2 and Buick Wins Best Concept For 2nd Year at EyesOn Design Awards at NAIAS January 12, 2016, Detroit, Michigan. A panel of design leaders representing worldwide automotive manufacturers and transportation design chiefs from top design schools around the globe today selected these vehicles to receive the following EyesOn Design Awards at the North American International Auto Show: * Production Car: 2017 Lexus LC500 * Production Truck: 2017 Chrysler Pacifica * Concept Car: Buick Avista Concept * Concept Truck: Audi h-tron Quattro Concept * Best Designed Interior: 2017 Lexus LC500 * Innovative Use of Color, Graphics and Materials: Acura Precision Concept * Human Machine Interface: 2017 Volvo S90 Chief Judges were: Chris Chapman of Hyundai, Dave Marek of Acura, Stewart Reed of ArtCenter College of Design, and Jack Telnack of Ford Motor Company (retired). 2016 marks the tenth year the EyesOn Design Awards have been an integral part of the North American International Auto Show.
