Self Study Program 950173 – The OBZ 7-speed Dual Clutch S tronic Transmission in the 2017 R8

VAG SSP 950173. The new 0BZ S tronic 7-speed dual clutch transmission is a truly sport-oriented gear box. Shifting occurs virtually without interrupting the power transmission.

The seven speeds provide a wide spread of ratios which reduce fuel consumption while retaining a close ratio configuration for better acceleration. It offers agility and easy gear shifting to meet customer expectations in terms of handling dynamics and driver convenience.

To review the basic functions of a dual clutch transmission with electro-hydraulic controls, please refer to eSelf-Study Program 951403, The 02E Direct Shift Gearbox, Design and Function.
