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...

Audi confirms autonomous tech for next-gen A8

Like so many of its rivals, Audi is hard at work getting its autonomous driving technology up to speed and ready to reach the market. And now it's revealed when we can expect that time to come – or at least in what form it will arrive. In announcing the achievements of its latest RS7 Piloted Driving prototype, Audi has confirmed that the system will be offered for the first time on the next A8, the upcoming iteration of the German automaker's flagship sedan. Just as we heard this past January, the next-gen A8 will be able to drive itself around town at speeds of up to 37 miles per hour. Ingolstadt still isn't saying when we can expect the new A8 to arrive, but considering that the current model has been around since 2009 (albeit with periodic updates along the way) and that its key rivals – the Mercedes S-Class and BMW 7 Series – are both much newer models, Audi shouldn't be waiting much longer to launch its new flagship. The announcement was made as part of the reveal for "Robby," the latest version of the company's self-driving RS7 concept. The previous version, dubbed "Bobby," was based on the same model, and gave our man Jonathon Buckley over at Translogic a run for his money around Ascari a few months ago. (We'll let you watch the video below to see who fared better). But the new version is a good 882 pounds lighter, lapping the Sonoma Raceway (previously known as Infineon or Sears Point) in 2:01.01. That's in what is ostensibly still a road car, just one that's operated by a computer. The fastest lap ever recorded on the full 2.5-mile circuit, in case you were wondering, was also achieved in an Audi, but that was the R8 Le Mans Prototype that Allan McNish hustled around in a 1:20.68 qualifying lap.

On one of the world's most challenging race tracks, the Sonoma Raceway in California, the latest generation of the Audi RS 7 piloted driving concept has surpassed previous top performances once again. Audi will be offering piloted driving for the first time in the upcoming generation of the Audi A8.

Audi builds 5-millionth vehicle with Quattro

Quattro, the trademark name Audi has put on its all-wheel-drive system engineered for passenger vehicles, recently celebrated its five-millionth installation. The driveline has been offered in more than 140 different vehicles since its introduction more than three decades ago.
The all-wheel-drive technology made its world debut at the 1980 International Geneva Motor Show, beneath the floorpan of the Quattro Coupé, a low-volume two-door. It didn't take consumers long to embrace Audi's innovative approach. While most four-wheel-drive systems at that time utilized heavy transfer cases or second cardan shafts, Quattro was virtually tension-free, light, compact and efficient. Most importantly, enthusiasts found it was especially suitable for sports cars.
Today, the automaker offers Quattro on its full line of passenger vehicles and it is unquestionably successful (the technology enjoyed a 43 percent take rate in 2012). On models with transverse-mounted engines (A3 and TT), Audi uses an electronically controlled multi-plate clutch with hydraulic actuator. Under normal conditions, the clutch sends power almost exclusively to the front wheels (if wheel slippage occurs, up to 100 percent of the torque may be sent to the rear). Vehicles with transverse-mounted engines (A4, A5, Q5, etc...) use a self-locking center differential sending 40 percent of the engine torque to the front axle and 60 percent to the rear under normal conditions (it is able to send the majority of the power to the axle with better traction when needed). The highest-performing Quattro systems use torque vectoring to further improve cornering grip and speeds.
