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 2018 Audi A5 and S5 Cabriolets are here just in time for winter

There are no big surprises with the 2018 A5 and S5 Cabriolet. As you'd expect, the convertibles share a design with their coupe counterparts, the A5 and S5 coupes, refreshed versions of which were unveiled earlier this year. Alongside the coupes and upcoming sportback models, the Cabriolets complete the A5 lineup. At least until another RS 5 comes along. In Europe, the A5 will have five available engine options, including three TDI engines maxing out at a 286-horsepower 3.0-liter, and two TFSI gas engines, with the most powerful putting out 252 hp. There will also be a choice of three transmissions including a six-speed manual, a seven-speed S-Tronic dual-clutch gearbox, and as an eight-speed automatic. For the US, though, the powertrains should be the same as the new coupe's, with a 2.0-liter turbocharged four-cylinder generating 252 hp and 273 lb-ft of torque in the A5, replacing the 220-hp turbo four in the previous model. An eight-speed automatic is a definite, although the existence of a manual A4 sedan for our market leaves some hope that a six-speed could be available in the A5 Cabriolet or at least the coupe. Audi also hasn't made final decisions on whether a front-drive model will be available here as it has been in the past. View 13 Photos The S5 Cabriolet, just like the two-door model, uses a new 3.0-liter turbocharged V6 engine that produces 354 hp and 369 lb-ft of torque, which is 21 more horsepower and 44 more pound-feet of torque than the old 3.0-liter supercharged V6 made. Despite the bump in power, the new S5 Cab hits 62 miles per hour in 5.1 seconds, just like the previous model. It is again electronically limited to 155 mph. And like the coupe, it will use an eight-speed automatic and get Quattro all-wheel drive standard. The A5 Cabriolet loses roughly 88 pounds compared to the previous model. The cars use an updated five-link front suspension and Audi claims the chassis is 40 percent stiffer than before. The soft tops have more insulation to cancel out road noise, take 15 seconds to open, and 18 seconds to close. You can do either at speeds up to 31 mph. The A5 Cabriolet will be available with Audi's latest array of driver assistance systems, including its navigation-linked adaptive cruise control and collision avoidance assist. A seven-inch display, seat belt microphones, Audi's Virtual Cockpit infotainment and gauge package, and a head-up display are available on the inside.
