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.

Horn, Hackenburg, Hatz to be fired as VW diesel scandal deepens

Volkswagen will sack three more high ranking executives, including the head of its US division, as the company's diesel scandal deepens. Reuters reported Thursday morning that the executives are: Michael Horn, who has led VW's US operations since January 1, 2014; Ulrich Hackenberg, who oversaw Audi's research and development; and Wolfgang Hatz, who was in charge of R&D for Porsche. A VW spokesman wouldn't comment in response to an Autoblog email. The moves come in the wake of longtime VW chief executive Martin Winterkorn stepping down on Wednesday. Volkswagen's board said at the time that it expected more personnel changes to follow. Volkswagen's board is scheduled to meet Friday, and Porsche CEO Matthias Muller has reportedly been named as Winterkorn's successor. The German auto giant was plunged into crisis last Friday when the EPA charged that the company manipulated software in its diesel-powered cars to pass US emissions tests. About 482,000 vehicles in the US are affected, and VW estimates 11 million around the world could have the rigged software. The revelations have prompted outcry from governments and regulatory agencies, and in the US, Volkswagen could face a fine of up to $18 billion. The departure of Horn, Hackenberg, and Hatz is a stunning downfall for three of the company's top and most visible executives. Horn had led US operations for less than two years, taking over from Jonathan Browning, who was well-respected but failed to reach VW's ambitious sales targets. Before overseeing Audi R&D, Hackenberg was hailed as a visionary for work in developing VW's modular architectures, which allow the company to save time and money by building many vehicles off the same chassis. Hatz had led Porsche R&D since 2011 and also was in charge of engines and transmission development for all of Volkswagen.

Next Audi RS4 to get an electric turbo?

We don't yet know if the next Audi RS4 will come to the US, but whoever gets it could find an electric turbocharger under the hood according to a report in Auto Express. The 4.2-liter V8 that has served for two RS4 generations is retiring from the line, replaced by a twin-turbocharged version of the supercharged 3.0-liter V6 used in the S4. But instead of using two sequential turbochargers - a smaller one to eliminate lag while a larger, more powerful turbo spools up - batteries charged by brake regeneration could power a first-stage electric turbo. The idea hasn't been publicly appointed for a particular model, as Audi's technical chief Ulrich Hackerberg has said that due to expense, that kind of setup "would only be used be used on the very top end models." Since the technology cuts down on the use of exhaust gases, it would also also help in markets like Europe where CO2 emissions are a factor. No matter whether it benefits from all conventional or some electric boost, the horsepower number for the twin-turbo V6 will be more than 420 hp but less than 503 hp, the rating of the V8-powered Mercedes-Benz C63 AMG. Auto Express believes Audi will want to maintain the power gap between the 333-hp S4 and previous, 444-hp RS4. With Hackenberg saying the new S4 will make more than 350 hp, that gets the coming RS4 up to at least 461, but AE figures it "could deliver as much as 480 hp." We'll find out sometime after the S4 launches next year.
