Multitronic® is a Continuously Variable Transmission (CVT) with a steel link-plate chain running in tension in an oil bath between two pairs of bevel wheels of variable diameter. In addition, it permits an exceptionally wide range of effective ratios. The differential is located in the same compact housing as the transmission. There are no fixed gear ratios. The resulting smooth and powerful acceleration ensures a high level of driving comfort. There are also advantages when towing a trailer, thanks to the high torque available over the entire engine speed range. The design and the low weight of the transmission reduce fuel consumption. Manual gear selection mode is available, as with the 6-speed Tiptronic® transmission and six simulated gear ratios can be selected. In the automatic mode on the multitronic® that calculates the optimum gear ratio with the aid of a Dynamic Regulating Program (DRP) according to engine load, the driver's preferences and driving conditions.
