Self Study Program 228 – Variable Automatic Gearbox multitronic 01J

VAG SSP 228. The name multitronic stands for the new variable automatic gearbox developed by Audi. The variable automatic gearbox is commonly known as the CVT gearbox.

The CVT concept improved by Audi is based on the long-established principle of the “chain drive transmission”. According to this principle, the reduction ratio between the shortest and the longest ratio can be controlled steplessly by means of a so-called “variator”.

CVT is the English abbreviation for “Continuously Variable Transmission”.

The new Audi multitronic with Tiptronic function offers a synergy of the best possible  dynamics, optimal fuel utilisation and the highest possible level of drive comfort.
