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.

2017 Audi A4 Deep Dive

Unchanged. Plain. Boring. These words have been used to describe the new 2017 Audi A4, but they all miss the point entirely. Yes, the design of the new A4 is evolutionary, rather than a ground-up restyling. But as they say in ancient High German, "If it ain't broke, don't fix it." Of course, if you're at all interested in the 2017 Audi A4, you've probably read all about it in the official press release a few days ago. So we'll cut to the chase and tell you the bits you don't already know: the American-market details. We spent a day at Audi headquarters in Ingolstadt last week finding out the latest and poking around the A4 in the metal. The new A4 is wider, longer, and roomier than before. The lines are crisper and sharper, but yes, the proportions have remained very similar. That was done on purpose, thoughtfully. Not out of laziness. Stand any two sequential generations of Porsche 911 next to each other and you'll find they are rather similar. And yes, people do complain about that. But they also complain about the property tax rate on their third home in Monaco. That familiar-looking body gets a shockingly low coefficient of drag of just 0.23. The improvements in drag come from fine-tuning details down to the placement of the side mirror (now on the door, rather than the triangular window panel) and the contouring of the inner edge of the side mirror, which gets little vortex generating bumps to improve the turbulent airflow in that area, reducing drag. Attention to detail and refinement of a successful design – not boring, lazy repetition. Another notable departure in the styling of the new A4 is equally subtle, but even more significant from a precision manufacturing perspective: the hood has no cut lines on its upper surface. Instead, the hood now wraps around the tops of the fenders, the cut line integrating with the sharp crease that runs down the entire body side. The creation of this cut line requires extremely tight manufacturing tolerances to enable the precise alignment of the hood and fender gap with the stamped-in crease in the door panel; misalignment would be obvious and catastrophic to the clean, simple design's flow. Now, let's rip off this Band-Aid: no, we won't be getting the Avant. Why? Because no one buys it, vociferous vocalizations on the Internet aside.

Audi's Q8 Concept previews a 2018 personal luxury crossover

Audi revealed the Q8 Concept here at the 2017 Detroit Auto Show, and it's just as we expected: a Q7 with frameless windows, an oversized grille, and a rakish "coupe-like" roofline. This concept is an exaggerated example of a vehicle that will almost certainly enter production to do battle with BMW's vanity luxury utility, the X6, and Mercedes-Benz's GLE Coupe. The coupe moniker doesn't really apply, despite the German automakers' best attempts to redefine the word, but otherwise the Q8 Concept delivers. It's two inches shorter overall than a contemporary Q7, on a similar wheelbase, so the basic proportions of the thing should make the jump to production. View 14 Photos The driveline is equally plausible: a plug-in hybrid setup pairing a 3.0-liter TFSI V6 with a 17.9-kWh lithium-ion battery. The concept's V6 hypothetically makes 333 horsepower and 368 lb-ft of torque, and a single electric motor integrated into the eight-speed automatic transmission adds 100 kW (134 hp) and 234 lb-ft of torque to the mix. Those numbers certainly make sense, considering the gas Q7 makes 333 hp (albeit with a supercharger) and the existing Q7 e-tron, which isn't sold here, pairs a 17.3-kWh battery with a diesel V6. Since this is a concept, production intent or no, the range numbers are also a little theoretical, but here's what Audi claims: a 60-mile EV range, and a total range of around 621 miles. Not shabby if you're taking a long road trip. The adaptive air suspension should also make it a comfortable one. Inside, this is a four-place vehicle; no third row, and no center rear seat, as is the trend with these things. The cabin is very clean and modern – typically Audi, although exaggerated a bit. Expect it to be toned down some for production, but this concept interior is a glimpse into the future. We'll have to wait until next year to see something closer to production-ready, but it's coming.
