Audi claims World Endurance Championship at Fuji

It's been a successful racing season for Audi so far this year. After claiming the drivers' title in the DTM series, the German automaker has successfully defended both its titles in the FIA World Endurance Championship.
The decision came after heavy rain ended the 6 Hours of Fuji after only 16 laps, virtually the entire race having been run behind the safety car. Although Alexander Wurz, Nicolas Lapierre and Kazuki Nakajima won the race for Toyota - the Japanese automaker's first this season - the second-place finish achieved by Allan McNish, Tom Kristensen and Loïc Duval propelled Audi Sport Team Joest out of its challengers' reach.
While the actual drivers' title still remains in contention, the battle now comes down exclusively to the two leading Audi trios: McNish, Kristensen and Duval hold the lead with 147 points ahead of André Lotterer, Marcel Fässler and Benoît Tréluyer, who hold 106.25 points in the standings. Either way, Audi will be awarded both the drivers' and manufacturers' titles in the series with two races still to go in Shanghai and Bahrain.

Le Mans champion Allan McNish retires from LMP1 racing

Having won the 24 Hours of Le Mans three times, the American Le Mans Series title another three times and, most recently, the FIA World Endurance Championship, Allan McNish doesn't have much left to prove. Which is why he's retiring, ending this stage of his 33-year driving career on a high note.
In a statement just released by McNish himself and his team at Audi, the Scotsman said "I've had a fantastically successful time with Audi and feel it's the right time to step back from Le Mans sports-prototype racing and to look at other opportunities."
Just what those other opportunities might be is another matter. He's raced in DTM, Formula One and the International Formula 3000 series, where he won two races in 1990. McNish, 44, is also part of the BBC Radio's F1 commentary team, serves as president of the Scottish Motor Racing Club and is often called upon by the FIA to act as a grand prix race steward. Audi says he'll continue to be part of the team, just not in the driver's seat. Given his success in endurance racing, he's surely got a wide variety of opportunities to pursue, and we're looking forward to seeing where he lands.

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.
