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 will spend less on future technology as it focuses on future technology

It seems the very thing meant to be saved by Audi curtailing spending could also take a hit as a result. A report from Reuters outlines a few ways Audi will cut costs in the wake of its parent company's diesel scandal. While focusing on EVs, autonomous driving, and new connected technology instead of its current vehicle portfolio, Audi is axing plans for a track to test self-driving cars as well as facilities meant to produce new concepts and batteries. Or, you know, exactly the kinds of things Audi is now focusing its efforts on. Some of this shouldn't come as a surprise. We already know about the death of the R8 E-Tron, a low-volume EV that wasn't going to make the brand much money and didn't pan out as a halo electric car quite like the company probably hoped. Then there's the new E-Tron crossover, which has been in the works for a while and will head a line of consumer-grade EVs from the brand – the kind that will make money as long as they sell in mass-market numbers, something Tesla has shown is possible. That project is surely safe, although perhaps it will now take longer for the EVs to gain autonomous abilities. This change in funding direction could mean that the planned autonomous track, dubbed IN-Campus as it was to be located in Audi's home of Ingolstadt, was going to be more for show than actual research, or that Audi thinks it can get the same outcomes in its existing facilities or new ones located elsewhere. (The company's work council is upset by the plan being put on hold, as it could mean more jobs leaving Germany.) There's also the very strong possibility that this provides a welcome opportunity for the company to cut some fat. Reuters notes that Audi spends more on R&D than rivals BMW and Mercedes-Benz, despite having the whole VW Group to leverage. While the diesel scandal was certainly not welcome, it may be forcing Audi and the other Group brands to take a closer look at balance sheets than they otherwise would have. The result of all of this could be a leaner company, assuming too much attention doesn't stray to low-volume EVs and away from what are still the core products.
