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.

2015 Audi TT's digital gauge cluster to spread throughout lineup

File this one under: "makes sense to us." According to Car and Driver, the slick new gauge cluster found in the 2015 Audi TT will expand to other models in the automaker's lineup. In the near term, expect the tech to make its way into the next R8 supercar (with a special performance display for that model), as well as the upcoming, all-new versions of the A4 sedan and Q7 crossover.
Audi's new customizable gauges first debuted at this year's CES - it uses a 12.3-inch TFT display, and, while similar to the systems found in the Cadillac CTS, XTS and Mercedes-Benz S-Class, this system has the ability to show full-screen, three-dimensional maps. We had a chance to check out the new display in-person at CES, and found it to be impressive, though we're curious to see how distracting it is while driving.
Car and Driver says the system is still undergoing small tweaks before Audi officially launches it in the TT later this year. From there, the display will be standard in the R8, but Audi is unsure about whether or not to offer it as a standalone option in the higher-volume A4 and Q7 models.

Audi Prologue concept goes for A9, we give it a ten

If you've been waiting for Audi to roll out a new design language, you need wait no longer as Ingolstadt is displaying just that at the Los Angeles Auto Show this year with the Prologue concept you see here.
Penned by Audi's new design chief Marc Lichte, the Prologue is earmarked to introduce a shift (if not quite a complete change) in design direction for the German automaker. The trapezoidal grille sits wider and lower than on existing models, with the wedge-shaped laser headlights positioned higher above new air intakes with blade elements. The profile rests balanced across its wheelbase to visually emphasize the all-wheel drive that is part of Audi's DNA, with flared arches inspired by the legendary Ur-Quattro. The rear section is inspired by yachts, angled forward to suggest motion, with a narrow strip of LED taillights, full-width diffuser element and twin trapezoidal exhaust tips.
Inside it's all light and surgically clean, with a horizontal dashboard integrating four touchscreen displays running its full width. The system even allows the passenger to select the route for the navigation system and swipe it on over to the driver's display. The headrests on the rear seats and the "sound spoiler" on the rear shelf deploy only when needed, unobstructing the rear view when not.
