Audi R8 lines up as safety car for Rolex 24 at Daytona

This weekend a new era begins in American sports car racing with the Rolex 24 at Daytona to kick off the new United SportsCar Championship, the freshly inked union between the Grand Am and American Le Mans Series. There'll be a wide variety of machinery lining up on the grid at the Florida speedway, including race-ready versions of the sports cars you can drive on the road, plus Daytona Prototypes, Le Mans Prototypes and even the DeltaWing. But at the front of the pack will be the Audi R8 5.2 FSI.
That's because Ingolstadt's flagship has been named as the official safety car for this, the 52nd annual Rolex 24 at Daytona. And so the R8 becomes the first pace car pressed into service for the United SportsCar Championship, although the model also paced last year's race (pictured above) when it was under the auspices of the Grand Am series.
The car in question appears to bear little in the way of modifications over the showroom version, save for some requisite graphics and maybe some emergency lighting to make it more visible - because while you wouldn't miss an R8 slicing its way through ordinary traffic on the road, it's another story entirely in a field full of competition machinery. Audi points out that the road-going R8 shares a good 50 percent of its components with the R8 LMS competing in the race, including its 5.2-liter V10 engine that's available this year with a new seven-speed dual-clutch transmission.

Audi A8 super high-tech headlight teased, whole car coming Aug 21

We have to wait one more week before we get to see the 2015 Audi A8 and S8, but it doesn't look like Audi is going to stay quiet until then. After releasing a pair of teaser videos over the last week, it has now released a first detailed picture of the new A8 revealing the trick Matrix LED headlight.
Between the high-beam and low-beam lights, the headlights contain 43 LEDs (not including those for the DRL/turn signal), but the innovative part of Matrix LED system is that a camera can control the high-beam lights - by either dimming them or shutting them off - when other vehicles are detected on the road to prevent the lights from distracting other drivers. Of course the big question remaining is if Audi can get these new headlights to pass the National Highway Traffic Safety Administration and its Federal Motor Vehicle Safety Standards. The taillights also get a cool design with 24 LEDs that use a sequential turn signal
As for the debut of the A8 and S8, we already knew the sedans would be unveiled on August 21 ahead of the Frankfurt Motor Show, but Audi finally made it officially official in a press release, which is posted below. Also be sure to check out the pair of teaser videos Audi has released for these cars recently.

166 MPGe diesel-electric Audi Q7 E-Tron Quattro gets real in Geneva

Despite some warnings that plug-in vehicles would not make a big impression in Geneva this year, the first big reveals from the Peace Capital are indeed PHEVs. For example, the diesel-electric Audi Q7 E-Tron Quattro, which right out of the gate comes at us with some impressive numbers: an all-electric range of 34 miles and the "potential" to hit 166 miles per gallon equivalent. Whatever scale Audi is rating the new Q7 PHEV on, 166 MPGe is a resounding success. As we might guess from the prototypes we've seen and hints we've had, the Q7 E-Tron Quattro is not some auto salon fantasy. The vehicle will go on sale at the end of this year, in the UK, at least. Availability in the rest of Europe and here in the US is likely but unspecified in the press materials we've seen so far. The real-world reality of the Q7 E-Tron Quattro means that specs like a 0-100 kilometers an hour (62 miles per hour) time of six seconds and a top speed of 225 kmh (139.8 mph), CO2 emissions of under 50 grams per kilometer and a total system torque output of 516.3 pound-feet should be ours to test in the not-too-distant future. This whole E-Tron program is turning out to be quite something. Who else is ready?
