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.

Notes from day one of the Rolex 24 at Daytona

We came to Daytona Beach, Florida where you can drive on the beach, gun shops outnumber doughnut shops and you can putt-putt and fish for alligators at the same place. But we're not here for any of that - we've made the trip with Audi in order to experience the Rolex 24 at Daytona, the first race in the 2013 Grand-Am season and the only 24-hour race in America.
Three teams are racing four Audi R8 Grand-Am cars - WeatherTech Racing, Rum Bum Racing and APR, which is running two cars. Shown to the world two years ago, the R8 Grand-Am is part of Audi Sport's R8 LMS customer racing program that was commenced in 2008, and ever since 2009 has been nabbing success all over the world: In four years it has taken 154 victories and 17 series titles. That is with less than 100 cars sold to customers throughout the world, and the trophies - either class wins or overall victories - have been gathered from all of the major endurance races except one: Daytona.

Audi A3 E-tron guest stars in Muppet video for Emmys

Following on its tiny role in 2015's hilarious Emmys promo, Audi is grabbing a somewhat bigger guest spot by throwing in an A3 Sportback E-tron in this year's video starring the Muppets. Jim Henson's famous creations are returning to television in the coming weeks, and they get this extra bit of marketing for the upcoming 67th Primetime Emmy Awards on September 20. Starring Kermit the Frog and Miss Piggy going out for lunch, the spot includes cameos by Julie Bowen from Modern Family and Viola Davis from How to Get Away with Murder. Joel McHale is the one that actually gets behind the wheel of the Audi, though. While the PHEV's appearance feels more forced more than last year, the clip provides a dose of nostalgia to Muppets fans ahead of their new show. The outtakes at the very end might actually be the major highlight here. Related Video:
