Whether or not guide transmission, seven-speed S tronic or eight-speed tiptronic, whether or not front-wheel or quattro drive—every of the six engine variants delivers tailored energy transmission. All A4 fashions come off the manufacturing line with an computerized transmission as commonplace.

The sportily balanced suspension ideally harmonizes with the character of the Audi A4. Clients can select between the usual setup and the game suspension. There are additionally two adaptive suspensions. One choice is the consolation suspension with damper management, which reduces the trip peak by 10 millimeters (zero.four in) and gives excellent trip consolation.

With its much more dynamic primary setup, it underscores the sporty character whereas sustaining consolation. Each managed suspensions are built-in into the Audi drive choose dynamic dealing with system. The identical applies to the steering, with dynamic steering, the automated transmission and the throttle valve obtainable for patrons as an choice.
