DSG & S-Tronic
DSG is a Direct–Shift Gearbox, which is a type of semi–automatic transmission. It is a dual–clutch transmission, which means it has two clutches: one for the odd gears (1, 3, 5, 7) and one for the even gears (2, 4, 6, 8). When you are driving, the DSG transmission will automatically change gears for you.
