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 Adaptive Cruise Control | 2017 Autoblog Technology of the Year Finalist

Not your father's cruise control, Audi's adaptive system is another step on the road to autonomous driving. That earns it a spot as one of our Technology of the Year finalists. Audi Adaptive Cruise Control can slow down or speed up your vehicle depending on the conditions. It's also capable of coming to a full stop and then resuming speed. This allows the vehicle to move with traffic without engagement from the driver using Traffic Jam Assist at speeds up to 40 miles per hour. It's not being marketed as an auto-pilot setup. Rather, this system can increase driver safety by automatically braking as the vehicle in front slows and then accelerating once the path becomes clear. The cruise control has five programmable settings to regulate distance between vehicles. Linked with the navigation system, Audi's ACC suite uses a camera and radar to respond to its environment, a key development for future systems that will need to communicate with the grid. The system can read street signs, allowing it to slow down or speed up. Additionally, when a destination is set, the vehicle will automatically brake when a turn is looming to alert the driver he or she needs to take action. It will brake through the turn and then speed up upon completing the maneuver. We especially liked this, as many navigation systems don't inform the driver when to turn or take an exit until the last possible moment. Further, when navigating curves, the Audi system will brake the vehicle and resume speed as conditions require. This Adaptive Cruise Control is a layer of artificial intelligence we can get on board with. It's like having a co-pilot to assist the driver when the inevitable fatigue or distractions appear. It engages like a normal cruise control system. Simply pull the stalk in the steering wheel mount, and there's a button to modulate the distance. We tested Audi's Adaptive Cruise Control on an A4, where it is an $1,800-option as part of the Driver Assistance Package. Working in combination with Audi's Virtual Cockpit and head-up display, ACC provides the driver a sense of awareness and greater level of information than other systems on the road. Companies like Volvo and Porsche offer similar setups, but we like the intuitiveness of the Audi program. Automakers have been saying for years that the autonomous technology is essentially here, they just need the infrastructure and regulations to catch up.

IIHS gives 90 models its Top Safety Pick award in one fell swoop

Although the Audi A7 and the Toyota Sienna are positioned on completely different ends of the automotive spectrum, they overlap in one important area: both earned a Top Safety Pick+ award from the Insurance Institute for Highway Safety (IIHS). They're among the 49 cars that received the distinction for 2021, while 41 additional models scored a Top Safety Pick (without the plus) award from the institute, bringing the number of winners to 90. Earning a coveted Top Safety Pick award from the IIHS is easier said than done. Recipients need to score a good rating in the institute's six crash tests, be available with a front crash prevention system that scores a superior or advanced rating in vehicle-to-vehicle and vehicle-to-pedestrian evaluations, and be offered with (but, crucially, not necessarily fitted standard with) headlights that are either good or acceptable. Vehicles that have good or acceptable headlights across the full range, regardless of trim level, are eligible for the Top Safety Pick+ award. The Hyundai Group (which includes Hyundai, Kia, and Genesis) earned more awards than any other carmaker, with 12 standard Top Safety Pick distinctions and five earning a Pick+. Volvo led the Pick+ chart with its entire lineup of nine vehicles. At the other end of the spectrum, Mitsubishi still hasn't earned a single award, and General Motors only nabbed one of each. Safety is spreading across market segments, according to the IIHS. It pointed out that, in 2020, there were no minivans or pickup trucks on the list of Top Safety Pick recipients. Fast forward to 2021, and the list includes the Honda Odyssey, the Toyota Sienna, and the Ram 1500 crew cab; the first two earned a Pick+. The full list of 2021 award winners is on the IIHS website. Note that, for some models, only units built after a certain date earned an award. This distinction reflects a change (usually in headlights) during the production run. Cars sold in the United States are safer than ever, but automakers still sell vehicles with a zero-star crash test rating in many global markets. Suzuki's 2020 S-Presso flunked a reasonably basic round of tests in 2020. Featured Gallery 2021 Hyundai Palisade View 12 Photos Audi Hyundai Volvo
