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, Fiat squabbling over numbers and letters

There have been rumors and speculation and prognostications about a Nissan Juke- and Mini Cooper-fighting Audi Q2 since 2012. There have been the same for a performance-oriented Q4 since 2011, perhaps previewed by the TT Offroad concept shown last year at the Beijing Motor Show. Turns out that those two alphanumeric combos are the only ones missing from the series Q1 to Q9 in Audi's trademark stable, and the Ingolstadt company wants to get them to make its badge sequence and crossover lineup complete. But Fiat owns them, and rumor is, CEO Sergio Marchionne appears to have no interest in selling them. Fiat has used the Q2 and Q4 like trim badges, identifying whether a company product has two-wheel or all-wheel drive. They did it with the Alfa Romeo 159 sedan, and they do it now on the Maserati Quattroporte S and Ghibli S Q4 sedans. Car magazine says Marchionne "may not be categorically opposed to selling the rights," but he absolutely won't do it to any fiefdom in the Volkswagen empire, which would leave Audi a jilted suitor. Why is Sergio being so serious? VW Group CEO Ferdinand Piech first starting waving torches on the bridge between the two companies when he said Alfa Romeo could sell four times as many cars if Volkswagen owned it, then burned the bridge when it continued to publicize its desire to buy Alfa Romeo. VW followed that up by throwing salt on the land around the destroyed bridge with its aggressive pricing in Europe during the worst of the car sales slump there, which Marchionne said was causing a "bloodbath." VW's final flourish was to set the river itself on fire, when a press officer said Marchionne wasn't qualified to head the European Automotive Manufacturers Association (ACEA) and VW would quit the organization if he did take the top spot. That is why, putting it optimistically, Audi looks to have a grim chance of getting the Q2 and Q4 marques from the Italian. So long as he is in power, at least: Marchionne said he's walking away from the job in 2018. Audi might have a better chance bending the knee to, and generously rewarding, his successor.

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.
