Audi spotted testing new S4 at the Nurburgring

Where there's smoke, there's fire. Only in this case, the smoke is the upcoming new Audi A4, and the fire is the S4 spotted undergoing testing in this latest batch of spy shots. Snapped in both sedan and Avant wagon forms while undergoing testing on and around the Nurburgring – where else? – the next-generation Audi S4 will of course be based on the new A4 that's anticipated to debut in Frankfurt this September. That means MLB Evo architecture and styling that takes a page out of the new TT's playbook. But in S4 trim, it'll be altogether more performance oriented. Expect an even more powerful version of the outgoing model's 3.0-liter supercharged V6, pumping out a good 340-350 horsepower to all four of its driven wheels. That power will help it keep pace with the new Mercedes C450 AMG Sport. It won't have to take on the new C63 AMG directly, though, as that'll be the job of the next RS4 that will slot above it. But since that model may never make it to US showrooms, this will stand as the flagship of the new A4 family as far as the American market is concerned. Related Video:

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 reveals R8 E-Tron Piloted Driving concept at CES Asia

Designed as they are to take the driver out of the equation, you might think that the idea of an autonomous vehicle would seem diametrically opposed to that of a supercar. But Audi disagrees. The German automaker has cooked up a series of "piloted driving" concepts that are increasingly focused on performance, and this could be the ultimate iteration yet. Audi's latest Piloted Driving demonstrator is based on the R8 E-Tron. It's altogether almost identical to the one we saw in Geneva, packing an electric powertrain to deliver 456 horsepower, 679 pound-feet of torque and a 0-62 time of 3.9 seconds. Only in this case, it can do it all on its own, without any driver intervention. To pull that off, Ingolstadt has fitted this show car with an array of sensors, including a new laser scanner, multiple video cameras, ultrasonic sensors and radar transmitters at both ends – all handled by a central "driver assistance control unit." It's the latest in a series of concept cars that has already included a version of the RS7 Sportback designed to lap the racetrack, and the Prologue concept that drove itself to CES. This concept was similarly unveiled at CES Asia, the Eastern counterpart to the tech expo we usually catch in Las Vegas. Just what the point is in engineering (or buying) one of the best-driving cars on the market and then handing over its operation to a computer, we don't quite get. But at least we can rest easy knowing that Audi is not giving up on performance as autonomous tech turns the driver into just another passenger.

The technology study is one of the highlights of CES Asia, and it brings together future technologies – which relate to lightweight design, high-performance drive systems and functions for piloted driving. The Audi R8 e-tron piloted driving concept car is based on the multimaterial Space Frame of the new production R8. A rear car body module made of carbon fiber reinforced polymer (CFRP) integrates the luggage compartment, which extends the frame structure. The walls of the luggage compartment shell are corrugated, so that they can absorb extreme amounts of energy with little material weight in case of a rear-end collision.
