The 2014 Rolex 24 at Daytona: What we learned, what we saw

Two days after the flag dropped on the 2014 Rolex 24 at Daytona, people are still trying to figure out what it might portend for the rest of the season. In 24 hours, two minutes and 24 seconds, 695 laps were completed by the car that crossed the line first. During that time, 67 cars began the race, 18 of them retired. There was that accident, and a red flag. There were supposedly slower classes beating supposedly faster classes. There were 16 caution periods, including that yellow flag. And then there was The Decision. And Then The Uproar. And then The Reversal.
There was also some pretty good racing, so let's have one last look at the weekend. Oh, and there was that 1964 Ferrari 250 GTO Series II...
If you want to skip the reading bits and go to the photos, there's a high-res gallery of 158 images above and a couple more below. Enjoy.

Audi promises next A8 on sale by year's end, LED Matrix lamps to be available [w/video]

Audi has just released details about its new Matrix LED headlamps, but just as illuminating as the new lighting technology is confirmation that the next A8 will appear "on the market at the end of 2013." While Audi is calling the model new, expectations - and the spy shots above - suggest more of a traditional mid-cycle refresh.
Audi says that its new A8 Matrix lights are comprised of 25 high-beam LEDs, clustered in groups of five paired with reflectors. Unlike traditional automatic high-beam setups, the Matrix array is so precise that it "blanks out light that would shine directly onto oncoming and preceding vehicles" while continuing to use full high-beam power on other sections of the road and shoulder not occupied by other vehicles. Further, the camera- and electronic brain-governed system can dim or extinguish LEDs as necessary to deal with traffic. The active system also differs from today's adaptive headlamps by not requiring servo motors to direct light, yet they can still function as cornering headlamps - ones that can predict a road's trajectory because they are linked with the car's GPS system. Interestingly, the system also works with Audi's optional night vision system. When the latter detects a pedestrian in the dark, it automatically flashes a batch of LEDs to put both the driver and pedestrian on notice about each others' presence.
Only one problem in all of this trick lighting business: they aren't legal here in the US, at least not yet. Audi and other automakers are currently petitioning the National Highway Traffic Safety Administration, trying to sell the government agency on the technology's safety benefits. For the moment, Matrix headlamps are likely to remain forbidden fruit, but you can check them out and see what you might be missing in the video below. As for the 2015 A8, we're guessing it'll surface at the Frankfurt Motor Show in September.

Audi calls R18 E-Tron Quattro its 'most complex race car'

Technically speaking, Audi's R18 E-Tron Quattro is quite technical. The German automaker says the diesel-hybrid is the "most complex race car" it's ever created. And we'll take their word for it. The Audi, which pairs a V6 turbodiesel powering the rear wheels with two electric motors, is all about connectivity, giving the car's crew the opportunity to constantly monitor the vehicle while it's racing. The car sends in a host of data each lap to the crew's computers, and the vehicle's telemetry system constantly keeps tabs on things like hybrid energy levels, cockpit temperature and boost-pressure levels. In all, the amount of data parameters is more than 100 times greater than in 1989, when Audi first tested a race car equipped with automatic data transmission capabilities. Audi first released specs on the updated version of the R18 E-Tron Quattro late last year, trumpeting the vehicle's advantages in competing in the LMP1 class of the 2014 World Endurance Championship (WEC). Audi made the car a little narrower and a little taller and it complies with a new WEC regulation requiring the front end set off by a new wing. Take a look at Audi's most recent press release below. AUDI R18 E-TRON QUATTRO WITH COMPLEX ELECTRONIC ARCHITECTURE • Telemetry connection between race car and pit lane • Permanent acquisition of far more than 1,000 parameters • Various electronic control units interlinked by a multitude of CAN Bus systems Ingolstadt, May 5, 2014 – The Audi R18 e-tron quattro is the most complex race car created in Ingolstadt and Neckarsulm to date. This not only applies to the mechanics. The electronics of the most recent LMP1 race car with the four rings is more sophisticated than ever before. The age of electronic data transmission from the race car on track began for Audi in 1989. At that time, an Audi 90 quattro in the IMSA GTO series radioed eight parameters to the garage where engine speeds and a few pressures and temperatures were plotted on printouts – a tiny step from today's perspective, but one that provided important insights at the time. Today, an Audi R18 e-tron quattro on more than a thousand channels, in cycles that in some cases only amount to milliseconds, generates data of crucial importance to a staff of engineers at Audi Sport. At Le Mans, the engineers constantly monitor their race cars for 24 hours.
