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.

2016 Audi S8 Plus Quick Spin

Congratulations, that big promotion finally came through, and along with it, a new company car. So go big or go home. Never mind the modest A8 L, with the sensible six-cylinder. The Earth-moving A8 L with its powerful W12, perhaps? No way. You didn't get to the top by being timid or ostentatious, so you choose the new-for-2016 S8 Plus, with a 605-horsepower version of Audi's 4.0-liter, twin-turbo V8, available with an $11,000 Dynamic package that adds ceramic brakes, a sportier exhaust, a rear carbon fiber lip spoiler so tiny you are surprised it does anything, and a boost in governed top speed from 155 miles per hour to 190. Yeah, that's the ticket. The 85-horse boost in power over the outgoing S8 comes from different valve timing, new exhaust valves, and modified turbochargers. The S8 Plus is docile enough around town to carpool to the company luncheons, but point it towards some wide open spaces, and it's a blistering executive express. Driving Notes Much of our Florida test was done in conditions ranging from damp to deluge. Despite the fact that the Audi had summer tires on its 21-inch wheels, the S8 was startlingly sure-footed. Thanks, Quattro all-wheel drive, and a set of better-than-expected Dunlop tires. Power is linear and progressive, and the eight-speed Tiptronic transmission is prepared to downshift at a moment's notice, but is never busy or intrusive. We seldom used the manual shift paddles behind the steering wheel. The comparison between the Dodge Charger Hellcat and this S8 Plus is admittedly absurd, but they are big, heavy, four-door cars with monster motors. And while the Hellcat wants you to hear and feel every engine revolution and supercharger whine, the S8 Plus does all it can to shield you from the drama taking place under the hood. Which is why you look down and suddenly you're going 90. "Dynamic steering" allows for adjustments in steering feel, and we weren't fans in the stiffest setting – it felt notchy and artificial. Comfort mode felt more natural and still gives you all the feedback you need. "Adaptive sport air suspension," though, we had no problem with. It makes short work of potholes and irregular pavement, but firms up when you are cornering – admittedly, in Florida, we had to seek out the rare corners. This is a state with roads designed using a T-square. The aluminum body weighs just 510 pounds. The overall weight of 4,685 pounds, though, means there is still a lot of mass to slow down and steer through corners.

Audi to enter third R18 following Loic Duval's huge crash

When we saw the picture above yesterday, our first thought went to driver Loic Duval. After hearing that he, miraculously, walked away from the annihilated heap that had been the number one Audi R18 e-tron Quattro, our next thought went Audi's hopes in this year's 24 Hours of Le Mans. With the race kicking off on Saturday, we couldn't be sure if the team would run a two-car effort (that would put them on even footing with the two-car teams of Porsche and Toyota), attempt to rebuild the decimated racer or bring in a new tub and start from scratch.
Turns out, Audi opted for door number three, importing an all-new chassis to replace the destroyed R18. According to Audi, the team pulled an all-nighter to ready the new car in time for scrutineering and the second round of qualifying.
