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 R8 E-Tron packs 456 hp and goes on sale this year

For the longest time, the Audi R8 E-Tron seemed like such a fantasy, we never really though it'd come to fruition. But it's here, in second-generation R8 form. It's really, actually, finally here. It looks like a electrified R8, too, with oversized, EV-spec wheels, and a revised front fascia that lends itself well to the more chiseled design of Audi's mid-engine coupe. Thanks to that nice shape and those air-slicing wheels, Audi has achieved a drag coefficient of 0.28 for the R8 E-Tron. The 92-kWh, T-shaped battery is actually integrated into the center tunnel behind the passenger compartment, so it helps with the car's weight distribution and center of gravity. The two electric motors are mounted at the rear. As for the specs, things look awesome: 456 horsepower, 679 pound-feet of torque, 0-62 in 3.9 seconds, top speed of either 130 or 155 miles per hour, a range of 280 miles and a charging time of less than two hours. And it's going on sale. Like, for real. Audi's press blast clearly states, "Upon customer request, the R8 E-Tron will be available for order in 2015 as an electrically powered sports car in supreme hand-built quality." Consider us stoked. Electrified: Audi R8 e-tron The second generation of the Audi R8 forms the basis for two more models. Audi has made major engineering developments in its high-performance electric sports car, the R8 e-tron. The latest evolution of the vehicle takes up the multimaterial Audi Space Frame from the new series-production model. The supporting structure was enhanced by a CFRP rear-section module comprising the luggage compartment. The walls of the CFRP luggage compartment well are corrugated. This way, in the event of a rear-end collision, more energy can be absorbed despite the reduced material weight. Thanks to targeted modifications to the outer shell and on the wheels, the Audi R8 e-tron achieves an aerodynamic drag coefficient (cd) value of 0.28. In terms of performance and range, the car enters entirely new dimensions. The large T-shaped battery is structurally integrated into the center tunnel and behind the occupant cell – optimally positioned in the car. It supports the dynamics of the R8 e-tron with its low center of gravity. Audi produces the high-voltage battery itself, for the first time based on a newly developed lithium-ion technology which was specially conceived for a purely electric vehicle drive.

2015 Audi Q3

There are two ways to approach a brand-new segment in the auto industry. First, an automaker can take a gamble and introduce a completely new vehicle, catering to the specific demands of the marketplace(s) in question. In the compact, premium CUV segment, we've seen Buick do this with the Encore, and Mercedes-Benz with the GLA-Class. The other option is to introduce a vehicle already sold in another market. Considering the amount of time it takes to bring a new vehicle from paper to production, there is plenty to gain in the short-term with this approach. It's not without its downsides, though, as we found after a week behind the wheel of the 2015 Audi Q3, a vehicle that was initially launched in 2011. Cute though it may be – it was referred to at least once by a passerby during our testing as "totes adorbs" – Ingolstadt's decision to introduce a vehicle that's already been on sale for four years, and is effectively approaching the last half of its lifecycle, leaves the Q3 at a significant disadvantage relative to the newer competition. Despite crossing its first auto show stage four years ago, the Q3 remains a handsome little bugger. Audi's designs, while conservative, tend to age very well, and the compact Q3 is no exception. It's like a scaled-down Q5 in most respects, although certain design pieces, like its more aggressively raked rear window and shorter front and rear overhangs, belie the significantly smaller Q3's figure. Due to its age, the Q3 was, fortunately, designed before the current A3 hit the market. That means it avoids the unattractive, minimalist dash of the A3, opting for a more traditional Audi design, with a strip of brushed aluminum on the passenger's side, a user-friendly center stack and a suitably large nav screen front and center. While the overall layout is attractive, the material quality is not what we'd expect of a newer Audi. There's nothing that feels exceedingly cheap – the plastics just feel old and too familiar. It's difficult to describe, but as soon as you climb in the Q3, things like the switchgear for the HVAC controls immediately remind you that this is a vehicle that's been on sale since 2011. While our definition of interior quality has evolved over the years, our idea of a driver-friendly cabin has not. The Q3 scores highly in this regard, featuring the elevated seating position that makes CUVs so popular with the general public.
