Audi moves to patent electric Quattro and active-shutter wheels

Audi might have a few tricks up its sleeve for the coming years, with the Brits at Autocar uncovering a pair of patent filings made by the German luxury brand. The first is something we've seen before - wheel flaps - while the second is an evolution of one of Audi's trademark technologies.
We last saw wheel flaps on the Ford Atlas Concept in 2013, but the futuristic fuel-saving tech has so far failed to arrive on a production car. Audi may be seeking to change that, patenting the flaps that open and close automagically based on airflow. They can also open if the brakes get too hot.
The second patent is an evolution of Audi's Quattro all-wheel drive. The new AWD system uses an electrically driven rear axle and wheel sensors to figure out when and at which corner the car might lose traction, and is targeted largely at hybrid offerings, which is a field Audi has only recently dipped its toe into.

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.

2016 Audi A3 Sportback E-Tron First Drive

While its parent company is still in the throes of an emissions scandal that has thrust the "green" credentials of automakers worldwide under the microscope, Audi is launching its first plug-in hybrid in the US. Audi is ready to double down on its electrified future, putting up its own reputation as collateral. This A3 Sportback E-Tron – a vehicle we've sampled in prototype form – is a tech-savvy plug-in car that could be the perfect vehicle to mark the brand's new commitment to an electric lifestyle. Straightaway, Audi USA President Scott Keogh addressed the TDI situation. He says he and the rest of the company are "shocked, followed by appalled, followed by anger, and now in the phase of drop-dead determination to make this thing right." Out of the 500,000 affected 2.0-liter TDI engines around the world, 14,000 are in Audis: about 3,000 A3 TDI sedans and about 11,000 A3 TDI Sportbacks. "It's quite simple. CARB and the EPA have told us these cars can stay on the road, they will stay on the road until we have a fix, and when we have a fix, we will absolutely fix these cars." The most important thing going forward, Keogh says, is regaining the trust of both the dealers and customers. Audi has been enjoying a bit of momentum in recent years, building a reputation for itself along the way. Audi came on the scene in the US in 1969, but it took until 2010 for the company to sell 100,000 units in a single year. Now, "In 2015, we're starting to look down the barrel of nearly doubling our sales in five years," says Keogh. The A3 achieves a 40-percent segment share, and for 75 percent of those buyers, it is their first purchase of a luxury brand. But as its own pace increases, the momentum of the industry as a whole has pulled Audi toward this foray into electromobility. Enter the A3 Sportback E-Tron. There's a little extra weight from the battery pack, but the suspension does a good job of keeping it unnoticeable while driving. The A3 E-Tron has several strengths working in its favor. First of all, as Keogh puts it, the hatchback is a "real, proper Audi – a real, proper, fully rounded driving machine." Qualifications such as "this is an electric car" don't matter. "People just want to buy a car," he says. It has the technology, build quality, and drivability of an Audi.
