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.

The super-luxury Audi Q8 concept is coming to the Detroit Auto Show

We've known the Q8 was on the way since last May, and now we'll get a better glimpse of the range-topping Audi SUV at the 2017 North American International Auto Show. The Q8 is, according to CEO Rupert Stadler, "a sporty Q derivative." It also has the same phonetic pronunciation at the country of Kuwait. To be clear, the vehicle coming to the Detroit show is the Q8 concept, so expect the standard treatment for thinly-disguised production cars like giant wheels and impossibly-small side mirrors. According to a leaked document from earlier this year, the production Q8 comes sometime in 2018. Like most teasers for auto-show reveals, this one only gives us a rough idea of what the car will look like. In this case, that's big, bold, and imposing. Or, as the press release states: "The octagonal Singleframe is considerably wider than that in Audi's current production Q models. Enhancing the forward positioned stance, is dynamic three-dimensional sculpting." We put the quote there to prove you can't make this stuff up. The next sentence in the release says there are design elements reminiscent of the 1980's Audi Quattro, which we consider a positive. According to the latest press conference schedule, expect the Q8 concept to debut at 8:00 AM on Monday, January 9.Related Video: Image Credit: Audi Detroit Auto Show Audi Crossover SUV Concept Cars Luxury 2017 Detroit Auto Show

Honda, Hyundai top car residual value / depreciation awards list

J.D. Power announced its 2022 U.S. ALG Residual Value awards Thursday, with Honda and Hyundai topping the charts at three models apiece in the industry-standard study. The term "residual" is an industry projection of how well a car will hold its resale value three years from the original purchase date – a key metric in calculating lease costs and projecting new-car depreciation.  Award winners included several enthusiast-friendly options, including the BMW 2 Series, Dodge Charger, Subaru WRX, Mercedes-AMG GT and Toyota Tacoma. Even the Ford Bronco was recognized, beating out the Jeep Wrangler in the Off-Road Utility segment. That may seem odd given the car's issue-plagued launch, but scarcity apparently trumps quality control issues over the longer term. Here's a scrolling complete list of winners broken down by segment: “Accurately forecasting residual values in the auto industry is a key factor in assessing an estimated $225 billion lease portfolio of vehicles in the United States,” said ALG VP Eric Lyman in the company's announcement. "The brands and vehicle models that rise to the top demonstrate that they score well across the award programÂ’s criteria, including manufacturersÂ’ superior design and quality." ALG looks at several factors to determine future value, which is especially tricky with new models. For 2022, 16 different brands were recognized across 29 segments. Behind Honda and Hyundai, Audi, Kia, Mercedes-Benz, Land Rover and Subaru all managed to chart with two different models. Here's the rundown of those who won in more than one category: Honda Civic Honda Passport Honda Odyssey Hyundai Accent Hyundai Kona Hyundai Kona EV Audi A6 Allroad Audi Q3 Kia K5 Kia Telluride Land Rover Range Rover Velar Land Rover Discovery Mercedes-AMG GT 4-Door Mercedes-Benz Metris:  Subaru  WRX and  Subaru Forester Toyota Tacoma  Toyota Tundra "The award process consists of evaluating 284 models through analysis of used-vehicle performance, brand outlook and product competitiveness," the announcement said. "Eligibility for a brand award requires a manufacturer to have model entries in at least four different segments. To account for differences across trim levels, model averages are weighted based on percentage share relative to the entire model line."   Audi Honda Hyundai Kia Land Rover Mercedes-Benz Subaru Toyota
