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 A4 TDI plans scrapped for the US

It comes as no great surprise, but Audi of America president Scott Keogh told Automotive News that the automaker has ditched plans to offer the 2.0-liter TDI-powered A4 here in the US. Despite what you may be thinking, Keogh claims the decision isn't based on the ongoing talks between parent company Volkswagen and US regulators regarding the diesel emissions scandal. (Currently, Audi and Volkswagen are awaiting EPA certification for their diesel engines in the US.) The reason, he says, is that the demand for diesel sedans is low here, particularly when compared to the company's lineup of crossovers. "The marketplace speaks, we listen to the marketplace, and the marketplace told us, 'Go with SUVs,'" says Keogh, presumably in his usual straightforward, assuring manner. That's not to say, though, that one doesn't have an effect on the other. We've already seen that the scandal has had an impact on sales. Now, in a country where many were already under the assumption that diesel engines were dirty and noisy, it's no revelation that automakers are less than enthusiastic about expanding their grease-burning offerings. While the news is a bit of a bummer for those of us who have long hoped for more widespread diesel options here in the States (and for whom the whole Dieselgate debacle is downright depressing), there's still plenty to look forward to in terms of greener, cleaner Audis. At the A3 E-Tron event late last year, Keogh was bullish on EVs, promising that it was just the first step in a "substantial commitment." Audi's plan is, in Keogh's words, to "start with the plugs, come in with the full BEVs and then keep rolling from there." He repeated these assurances at the LA Auto show, saying that he expects 20 to 25 percent of Audi's sales to be plug-in vehicles by 2025. Plus, despite the whole diesel thing (which, to be fair, affects far fewer Audi cars than Volkswagens), Audi has been killing it lately. February sales marked a streak of 62 consecutive months of record sales in the US. For an automaker that is repeatedly saying that it believes the future is in electrification, this bodes well for us. Related Video:

Race Recap: 2013 Twelve Hours of Sebring, cakewalk up front, grindfest out back [w/spoilers]

This year's 12 Hours of Sebring wasn't exactly a foregone conclusion because we're still talking about racing, and anything can happen when the speeds are as high as the adrenaline and the desire. But we're still talking about Audi bringing it's two top-spec racers - and its huge budget and its nearly neurotic attention to detail - to a race that it uses as a test bed for The 24 Hours of Le Mans and as a way to open the endurance racing season with a victory.
Besides, 12 hours is a long time, especially at Sebring, and things didn't go all Audi's way. On top of that, although it was a pretty quiet race, behind the Audis things got even grimier, with plenty of battles, plenty of mechanical issues, and the new BMW Z4 GTE and Viper GTS-R being race tested. Oh, and that brand new chromed-out DeltaWing...
