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 testing long-tail version of R18 e-tron quattro for Le Mans

Race teams are always looking for ways to shave hundredths of seconds of their lap times. Case in point: Audi is making some slight changes to its prototype racecar to make it ever so much more slippery as it cuts through the air.
Debuting at the second round of the FIA World Endurance Championship at Spa on May 4, Audi will be testing a long-tail version of its R18 E-tron Quattro racecar. As its name suggests, the long-tail car gets a lengthened rear section with the goal of improving aerodynamics. The long-tail will be run alongside the standard version of the racecar as a testbed for possible changes that might be in store, heading into the 24 Hours of Le Mans.
Audi did not say how many inches were added to the racecar, but as you can see in the image above, "long-tail" definitely doesn't take on the same meaning of classic long-tail cars of the past such as the Porsche 917. More information about the car, Audi's team and even some info about the track itself can be found below.

Audi reveals facelifted A7 and S7 in Europe [w/videos]

Audi has revealed the nip/tuck and stylistic upgrades for the A7 that we got clues to in spy shots from back in January. The single-frame grille has been subtly reworked along with the lower front fascia and headlilghts. Those bulbs are underlined by a new design for the LED DRLs, and - in Europe - they can be had with Matrix Beam LEDs that come with dynamic turn signals. Out back is a tweaked bumper, as well as new exhaust tips and taillights with an LED pattern that mimics the front lights.
Cockpit inhabitants get new surface treatments like the aluminum and Beaufort walnut inlays, Valcona leather and five possible colors for the seats. The company's MMI Navigation Plus with MMI Touch is fitted with an Nvidia chip for faster graphics processing, and LTE-enabled internet connectivity is standard.
Up front, the 3.0-liter bi-turbo TDI gets a power boost to 320 horsepower and is attached to an eight-speed transmission; a seven-speed S tronic transmission is paired to the rest of the line. The revised 3.0-liter V6 TDI recently discussed at the Vienna Motor Symposium also joins the lineup, here offered in both the 272-hp and 218-hp variants, that latter "ultra" version said to return 50 US miles per gallon.
