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.

Audi Q7 E-Tron confirmed?

Rumors out of Australia say we'll be seeing a new variant of the Audi Q7 when the next-generation models bows in a few years. Joining the diesel and gas range will be the second production member of Audi's E-Tron family, which was introduced by the R8 E-Tron, but will actually see production in the form of the A3 E-Tron.
Speaking with Audi's managing director in Australia, Andrew Doyle, Car Advice asked what the future held now that the electrified R8 had effectively been shelved. "I don't see it [R8 E-Tron] as a major thing for us. We'll launch [locally] with A3, followed by Q7..."
The new Q7 will share its platform with the Volkswagen Group's two other large SUVs, the Porsche Cayenne and Volkswagen Touareg. But, as Car Advice is quick to point out, the Porsche and VW variants are slated for arrive next year - the second-generation Q7 won't arrive until 2015. Doyle refused to explain the discrepancy.

Audi considering other variants, turbo V6 for R8

More details from the Audi R8 event at Spain's Ascari circuit have met the Internet, and they provide more intel on the supercoupe will evolve over the second generation. First, they note some small differences in stance with this new car, being wider than the current car and sitting 30 millimeters (1.18 inches) lower. Compared to its Lamborghini Huracan brother, it gets three extra centimeters in the wheelbase. Filling out the power numbers, the 'entry-level' V10 engine at launch rolls out 540 horsepower and 399 pound-feet of torque, does the 0-60 mile per hour dash in 3.5 seconds, and hits a top speed of 200 mph. The V10 Plus model rocks 620 hp and 412 lb-ft, which slices 0.3 seconds off that acceleration time and adds five more mph to the top speed. They'll transfer their power through a seven-speed S-tronic that shifts faster than before, and it will in turn send power through an electronically-controlled clutch at the front axle and a constantly variable limited-slip differential at the rear axle. The power split is said to default to 42/58 front-to-rear, but 100 percent of the torque can be sent fore or aft. Benchmarked against the 991-series Porsche 911, driving sensations travel through an electromechanical steering setup that can be had with a variable rack if preferred, leading to standard 19-inch wheels with the option of 20-inchers and tires developed specifically for this car. A Performance setting offers dry, wet, and snow modes; that first setting turns the ESC off except for situations of impending doom, and Audi racer and test driver Frank Stippler told Top Gear that understeer is reduced, to which TG added "it oversteers at will." Stippler said it's "a lot closer to the GT3 race car than ever before," and even though it's "a lot" less intense than the Huracan, it's just as fast on the track. His estimate is that the new R8 will lap the Nurburgring between ten and 15 seconds faster than the current car. R8 technical lead Roland Schala said the new chassis opens up new avenues of development because "there's no problem to change it," mentioning models like a Clubsport or Superleggera as no longer forbidden. Differentiation could come from a wider engine mix, too. Markets like China need smaller displacements, so Audi's twin-turbo V8 is expected to join the line-up at some point, bringing 500 horsepower.
