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.

Audi pits S3 against Ur-Quattro on gravel

If you had to pick a winner between the latest Audi S3 and the original Audi Sport Quattro, which would it be? Both hot hatches pack around 300 horsepower and all-wheel drive, but they're separated by a good thirty years of development.
To find out, Audi took both to the old rally circuit in San Remo. Behind the wheel of the Ur-Quattro they put none other than The Stig himself - no, not the Top Gear test bot, but Stig Blomqvist, the Swedish former rally driver who drove the Quattro to the World Rally Championship in the mid-80s. In the S3 they put someone named Hermann Müller, who as best we can tell was one of Auto Union's original Silver Arrow drivers - but he died in 1975, so it's probably the guy who writes for the Audi magazine. Regardless, the contest was pretty close, so it's worth checking out in the 2:26 video clip below.

Audi revisits Ahab on desert island paradise in new ad

Well, call us Ishmael. Long ago (okay, about eight months), Audi debuted an ad during the NFL playoffs called "Ahab." It showed a salty tow truck driver and his years of catches. During that time, one particular car eluded and haunted him - a white Audi A6, whose Quattro all-wheel-drive system had no issues with the inclement conditions.
Now, there's a sequel that has Ahab, not dead and not missing any legs, on a tropical island. What he doesn't realize, though, is that the white whale (which, Audi, if you're going to associate an animal with a luxury sedan, a whale isn't the best choice) has followed him. Take a look at chuckle-worthy spot below, and then click over and see the spot that started it all from back in January.
