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.

Conquest and controversy conclude the 2014 Rolex 24 at Daytona [spoilers]

If you don't wish to know who won the 2014 Rolex 24 at Daytona, you should avert your eyes right now. We'll even give you a double-space to skedaddle...
For those of you still with us, the first race in the United SportsCar Championship (USCC) is done, but the discussions about it certainly won't end for a while. Daytona Prototypes claimed the first four overall places, the top spot taken by the No. 5 Action Express Coyote-Chevrolet Corvette DP driven by Joao Barbosa, Christian Fittipaldi, Sebastien Bourdain and Burt Friselle. The 16th and final caution of the race bunched the field up for an eight-minute sprint to the flag, so the first place getter finished just 1.4 seconds ahead of the No. 10 Wayne Taylor Racing Dallara-Chevrolet Corvette DP driven by Max Angelelli. Third place went to Brian Friselle in the No. 9 Action Express Chevrolet Corvette DP, 20 seconds down. Chevrolet power hasn't taken the overall win since 2003, eleven years later it scores a one-two-three-four. The No. 6 Muscle Milk/Pickett Racing ORECA-Nissan 03 scored fifth place, the top LMP2 finisher.
The Prototype Challenge class win went to the No. 54 CORE Autosport team of Colin Braun, Jon Bennett, Mark Wilkins and James Gue.

Audi A3 E-Tron starts at $38,825

Audi has announced the pricing for the new A3 E-Tron plug-in hybrid, listing the five-door's base price at $38,825. Adding the mid-range Premium Plus elevates the price to $42,925, while the top-of-the-line Prestige will demand $47,725. Of course, like so many hybrids the A3 e-tron's price is not so simply explained. The PHEV will likely be eligible for a $4,168 federal tax credit, while additional state tax credits are also available depending on where you live. And, if Audi's announcement isn't exciting enough for fuel-sippers across the country, we have another piece of good news – the A3 e-tron's configurator is live. While it's no different than any of Audi's other online configurators, potential owners can get a great rundown of the A3 E-Tron's entire options sheet. There's the usual array of options ranging from an MMI package on the base model, to a Technology Package on the mid-grade model, and a Sport Pack on the Prestige trim. With just a bit of fiddling – and while staying out of the accessories catalog – we were able to run the A3 E-Tron's price up to $49,025. That's just shy of what the car starts at in Germany. You can check out the official press release on the E-tron MSRP announcement below, or just head over to Audi's US consumer website and have a go with the configurator.
