2015 Audi A3 E-Tron [w/video]

Over the years, we've had a chance to test a lot of Audi E-Tron vehicles, from very early all-electric prototypes (back then we only got to sit in the passenger seat) to the A6 L E-Tron PHEV and the A1 E-Tron plug-in hybrid. All of them were concepts and promises, merely whispers of what was possible, even as the Nissan Leaf, Chevrolet Volt and two Tesla models were making waves in the marketplace.
As we learned last year in our Deep Dive of the E-Tron project, all of the concepts, prototypes and rumors have finally come to fruition in this A3 Sportback E-Tron. Previously, we were given a chance to drive a prototype, but it was only very briefly. Last week, we finally got to run a production-representative example through the hilly roads between Vienna, Austria and Munich, Germany. After spending a solid day with Audi's first marketable E-Tron vehicle, we can say that it's a most amazing bit of engineering, in particular for the way that Audi has done so much to hide the fact that this is an electrified vehicle. Not entirely, of course, but the idea was to make the A3 Sportback E-Tron a no-compromise PHEV. And that means it drives and feels, in many ways, like the standard A3 Sportback despite over 700 extra pounds. Oh, and there's a charge port hidden behind the four rings in the grille.

Audi celebrates 25 years of TDI

Nope, the diesel engine never really did go out of style for Audi. Now, the German automaker has released a video reminding the world of its persistence with the oil-burners and is commemorating the Silver Anniversary of Audi's first commitment to turbodiesels in 1989. And, yes, there are some road racers shown in the clip, so some of those bad boys actually move pretty well. Audi engineers on camera admitted to some of the early TDI engines being "slow" but still valuable for their torque and, obviously, their fuel economy relative to gas-powered engines. A bunch of tinkering later, though, and Audi says its diesels can be a legitimate "part of a performance car" and has even overcome the issue of noisiness that's often associated with diesels. The automaker made some news in these parts a few years back when its Audi A3 TDI won the 2010 Green Car of the Year at the annual LA Auto Show in late 2009, and the model even succeeded a fellow diesel (the Volkswagen Jetta TDI) to boot. Granted, diesel sales aren't nearly as popular in the US as they are in Europe. Still, Audi last year boosted its diesel sales in the US by 40 percent to 10,076, which was about a tenth of what sister company Volkswagen sold in diesels last year in the States. And things have looked even rosier this year for Audi's TDI sales. Through June, Audi diesel sales have almost quadrupled from a year earlier to more than 8,100 units. Check out the 150-second video on Audi's 25-years of TDI production below.

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.
