Audi celebrated its 40th anniversary this year with quattro all-wheel drive. In honor of this event, the company published a number of photographs and revealed the history of testing this technology. For example, one of the pictures shows how, in 1986, the Audi 100 all-wheel drive sedan, managed by rally driver Harald Demut, was able to ride a ski jump in the Finnish city of Kaipola. At the same time, during this unusual and risky test, the car was shod with summer tires.

In 2005, Audi successfully repeated this climb on the A6 quattro. In 2019, rider Matthias Ekström driving an Audi e-tron quattro, which is equipped with three electric motors, was able to overcome the steepest stretch of the Straif ski track in Kitzbühel, where the elevation reached 85%.

The history of quattro itself began in 1977, when the first test prototypes equipped with all-wheel drive set off for testing in the Alps. Then the car, shod in summer tires, was able to overcome the rise covered by ice and snow with a steepness of 33%. After that, the leadership of the German company approved the serial development of a promising all-wheel drive.

As a result, Audi Ur-quattro became the world’s first mass-produced car with permanent all-wheel drive. The car premiered in 1980 at the Geneva Motor Show. Six years later, the company introduced the second generation of its quattro technology, equipped with a Torsen mechanical lock differential. The first car to receive an upgraded four-wheel drive system was the Audi 80.

In 1995, Audi began mass production of four-wheel drive diesel models. Ten years later, the quattro system began to use an interaxle differential with the possibility of asymmetric torque distribution. In 2007, a viscous coupling appeared on the front axle in the Audi R8, and a sports differential a year later. In 2016, the quattro ultra technology debuted.
