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.

2015 Audi Q3 is ready to woo America's young and upwardly mobile

You can hardly blame Audi for its decision to finally bring its Q3 compact crossover to America, even though it's been on sale in other global markets since 2012. CUVs of all stripes are red hot, and the number of players in the US entry-level premium segment is mushrooming. Rapidly growing Audi simply can't afford to be left out of the discussion in favor of vehicles like the BMW X1, Land Rover Range Rover Evoque, and even small near-luxury entries like the Buick Encore, if only because capturing these customers could result in subsequent sales of more profitable models down the road.
Audi evidently intends to attract these new, younger customers by spoiling them in decidedly unGermanic fashion: by offering lots of standard equipment. Peruse the spec sheet on base models from rivals and you'll see things like manually adjusted faux leather seats, conventional projector headlamps, and little in the way of frills. By comparison, the 2015 Q3 comes with an embarrassment of standard features, including heated and power-articulated leather seats, panoramic moonroof, Xenon headlamps with LED accents and keyless start.
First impressions of the four-cylinder, 200-horsepower Q3 revealed here at the Detroit Auto Show are very positive, with a rakish (if overly familiar) shape and a fair amount of utility with up to 48.2 cubic feet of storage with the rear seats folded. If Audi can price the Q3 similarly to the entry-level BMW X1 sDrive28i ($31,825 delivered) when it arrives this fall, we think it'll sell like hotcakes - just like its Q5 big brother.

Toyota, Lexus dominate KBB's Best Resale Value Awards

Toyota and Lexus stormed the 2014 Kelley Blue Book Best Resale Value Awards, winning a combined 18 categories including best brand and best luxury brand. This marks the third year in a row that both automakers have won the Brand and Luxury Brand resale value awards. In all, Toyota won 11 categories and Lexus won seven.
Honda made a good showing, as well, winning two segments (Accord Plug-In Hybrid and Civic Si) and putting one car on the top-10 Best Resale Value list (CR-V). Chevrolet did even better, winning two segments (with the V6 Camaro and the Corvette) and placing three cars on the top-10-overall list (again, the Camaro and Corvette, plus the Silverado 1500).
The other winners came from Jeep, Dodge, Infiniti, Subaru and Audi. To give you a clearer picture of the Toyota and Lexus domination, their 18 mentions represents more than half of the 34 awards (including the top-10-overall list).
