The 2013 Rolex 24-hour race at Daytona comes down to the last hour [spoilers, w/video]

It took 24 hours to run the race, but it was the last one was stuffed with the high action as four cars were still trying to figure out how to gain victory on the track and in the pits. Along with the obligatory crashes, spins, mechanical issues and retirements had come numerous penalties, a double-digit number of full-course yellows and two hours of fog that turned early Sunday morning into a stretch of parade laps.
The final hour would make up for the morning - drivers who might have been happy just to get on the podium had a shot at victory as the end of the race approached, and that turned into a few gambles that paid off, and at least one that didn't...

Next Audi R8 to be up to 130 pounds lighter

"Simplify and add lightness," as Lotus founder Colin Chapman said. In a world where even supercars are subject to environmental, efficiency and emissions standards, lighter vehicles are being looked on as a sort of panacea - make it lighter, and it's automatically faster, more agile, easier to brake and better on gas.
Knowing this, it comes as no shock that Audi is looking at ways to lighten up its next-generation R8, with the brand's head of technical development Ulrich Hackenberg targeting a 110- to 130-pound diet for the mid-engine rocket. This supports previous reports regarding the focus for the next R8. Motor Trend reports that aluminum and carbon fiber feature heavily in plans for the next R8, which should go a long way toward slimming down even the lightest of R8s, the 3,678-pound V10 Plus model.
There's more over at Motor Trend, including the buff book's attempts to get Hackenberg to discuss powertrain options for the next R8.

Audi Nanuk Concept likes Parcour, puts four rings on it

Without a doubt, one of the coolest (and weirdest) debuts from this year's Geneva Motor Show had to be the Italdesign Giugiaro Parcour concept. And ever since the off-road performance coupe with Lamborgini guts made its debut, we've sort of been smitten with it. We figured this neat two-door would be a one-and-done show car, but to our delight, the folks at Italdesign worked with Audi to create this, the Nanuk Quattro Concept, which makes its debut here at the 2013 Frankfurt Motor Show.
Unlike the original Parcour, the Nanuk ditches the high-revving Lambo-sourced 5.2-liter V10 in favor of a twin-turbocharged 5.0-liter diesel V10. That's a beast of an engine, and with 544 horsepower and 738 pound-feet of torque on hand, it means the 4,189-pound, all-wheel-drive Audi can scoot to 62 miles per hour in under four seconds. Of course, being a diesel, it's surprisingly efficient, and we're told the Nanuk can achieve up to 30 miles per gallon.
As much as we sort of hate the term, the Audi Nanuk is a proper coupe-crossover if we've ever seen one, and utilizes the automaker's next-generation adaptive air suspension (the Parcour had a different pushrod arrangement) that offers a range of almost three inches of height adjustment. There's also an integral steering setup, meaning the rear wheels can turn up to nine degrees in the opposite direction of the front rollers, improving maneuverability.
