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.

2015 Audi A3 Sedan priced from $29,900* [w/video]

One year after the all-new Audi A3 bowed in Europe, the US finally will get the 2015 A3 sedan in 2014, and the German automaker announced yesterday that it's priced from $29,900 (*not including destination, and we've reached out to Audi asking for the price of delivery). A bit later in 2014, the A3 Cabriolet will be released along with the S3 sedan. The A3 Sportback will be a 2015 model, though it will only be offered as a gasoline-electric hybrid. Prices weren't given for those models and, sadly, the three-door hatch isn't slated for US consumption.
The A3 sedan will be offered with three engine choices, all of them featuring direct-injection, turbocharging and four cylinders: a 1.8-liter TFSI, 2.0-liter TFSI and 2.0-liter TDI - that last one's a diesel. If you count the S3 sedan, that's another engine in the lineup - a 296-horsepower version of the 2.0 TFSI.
As we were told at the 2014 A3's "unofficial" world debut in New York City earlier this year, Audi says US customers won't get the option of a six-speed manual transmission, as the Europeans do. All engines will be mated exclusively to a six-speed dual-clutch transmission.

Audi TT Quattro Sport Concept takes the next-gen to the extreme

There's little doubt that the new Audi TTS and its 310-horsepower, 2.0-liter, turbocharged four-cylinder will be very quick when released to the general public. As a means of reminding us that Audi can do much more with the little TT, though, the German manufacturer has presented this, the TT Quattro Sport Concept, alongside its litter of new sports cars.
Complete with a 420-horsepower, 2.0-liter, turbocharged engine - yes, it really puts out 210 horsepower per liter - the TT Quattro Sport can snap to 62 miles per hour in just 3.7 seconds. 331 pound-feet of torque is also on offer, meaning this one-off TT outguns the TTS by 110 horsepower and 51 pound-feet of torque.
An S-Tronic transmission shuffles the power about, while the car itself rides on a lowered and stiffened suspension. 20-inch alloys are featured with centrally locking, racing-style hubs. Those racy wheels are housed in wells that have had their arches stretched an additional 1.18 inches, which, along with the lowered suspension, contribute to the TT's aggressive looks.
