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.

Recharge Wrap-up: Schaeffler 48V mild hybrid Audi TT, Georgia Power charging stations

Schaeffler will test a 48-volt mild hybrid system in the Audi TT. A lithium-ion battery powers an electrified rear axle, which supplements the power provided to the front wheels from the internal combustion engine. The system includes a belt-driven starter generator also running on 48 volts. The car has driver-selected Sport and Eco modes, the latter of which maximizes all-electric driving at low speeds for increased fuel economy. The rear axle can also support the front when more traction is needed. Sport mode wrings out every bit of performance from both the internal combustion and electric motors, with torque vectoring between the rear wheels offering extra stability. Read more at Green Car Congress, or in the press release from Schaeffler. A man has built a near-life-size replica of a Tesla Supercharger out of Legos. Robert Turner's ode to the charging station stands at 42.5 inches tall (which looks impressive standing next to a real Model S), and took over three months to build. Turner showcased his Lego Supercharger at the Brickworld Chicago Lego convention, and he goes into more detail about the painstaking process of forming his creation out of tiny plastic bricks in a video interview. See the Lego Supercharger and read more at The Brothers Brick. Georgia Power is opening 11 new EV charging stations around the state. The charging islands – which are located at various Georgia Power locations – offer DC fast charging with CHADeMo/SAE Combo plugs as well as Level 2 208/240-volt chargers. Customers can pay with either a Georgia Power or ChargePoint card. These first chargers are part of a larger plan by the utility to roll out 61 charging islands throughout Georgia by the end of 2016. See a list of locations and learn more in the press release below. Georgia Power opens 11 new EV charging islands First phase of statewide public charging infrastructure completed ATLANTA, Sept. 30, 2015 /PRNewswire/ -- Georgia Power announced today that the company will open 11 new electric vehicle (EV) charging islands to the public on October 1. The new charging islands, located at Georgia Power properties across the state, mark the completion of the first phase of planned charging infrastructure being developed by the company which will include approximately 61 community charging islands for public use statewide by the end of 2016.

2016 Mazda MX-5 Miata named World Car of the Year

Kicking off Day Two of the New York Auto Show, the World Car of the Year awards are finally being handed out. The overall winner is, as God himself intended, the Mazda MX-5 Miata. It beat the Audi A4 and the Mercedes-Benz GLC-Class. The unique thing about these awards are that they aren't limited to the US domestic market (that's why they're called the World Car of the Year awards). For example, nominees for the overall award included the Skoda Superb, Renault Kadjar, and Subaru Levorg. In the Performance category, the forbidden fruit was repped by the Honda Civic Type R. But both the Civic and the Mercedes-AMG C63 Coupe were beat out by a far more expensive competitor – the new Audi R8. The fourth-generation Toyota Prius and the second-generation Chevrolet Volt, were two of the big finalists for the World Green Car of the Year award. They both lost out, though, to the Mirai fuel-cell car. Yes, a hydrogen car beat out two of the world's premiere hybrids. The luxury race that was perhaps the hardest to predict. That's because each of the three finalists have received near universal acclaim. In the end, though, the BMW 7 Series beat out the Audi Q7 and Volvo XC90. Finally, we have the World Car Design of the Year, where the overall winner (MX-5) and the Mazda CX-3 faced off against the new Jaguar XE. While both the CX-3 and XE are handsome vehicles, the WCOTY committee realized the answer is always Miata, and awarded Mazda's iconic roadster another 2016 award.

MAZDA MX-5 - 2016 WORLD CAR OF THE YEAR NEW YORK – March 24, 2016 - For Immediate Release The Road to World Car journey ended today with the declaration of the MAZDA MX-5 as the 2016 World Car of the Year. The winner was announced during a press conference hosted by the New York International Auto Show, Bridgestone Corporation and Autoneum. 2016 marks the 10th anniversary of the partnership between World Car and the New York show, and the third consecutive year that the World Car Awards have retained their ranking as the number one automotive awards program in the world in terms of media reach. Mazda Motor Corporation is no stranger to the World Car Awards program – now in its 12th year. The Mazda2/Mazda Demio was the 2008 World Car of the Year. While the Mazda3 (2014), Mazda6 (2013) and Mazda MX-5 have all earned "Top Three in the World" status as voted by our 70 plus international automotive journalists that make up the jury.
