All engine versions of the open-topped two-seater come standard with a manual six-speed transmission. It has a lightweight magnesium housing and gearshifts are short, light and precise. Audi also offers the highly efficient six-speed S tronic as an option for both TFSI units. As with the manual transmission, its internal gearing features sportily short ratios. The tall top gear helps reduce engine speed and fuel consumption.
The six-speed S tronic switches gears comfortably within just a few hundredths of a second with no perceptible interruption of pulling power. In manual mode, it is controlled via the selector lever or the paddles on the steering wheel. In automatic mode, the position D prioritizes lower rpm for lower fuel consumption; the shift strategy is sportier and engine speed level higher in the characteristic for the position S.
Attractive features: freewheeling and launch control
Another strength of the six-speed S tronic besides the ultra-compact packaging is the fuel-saving freewheeling. It is activated when the Audi drive select system (optional on the TT*, standard on the TTS*) is set to efficiency mode and the driver lets off the accelerator. All TFSI engine versions feature the launch control start program, which enables full acceleration from a standstill with controlled wheel slip.
Like all dual-clutch transmissions, the six-speed S tronic comprises two independent transmission structures operated by two radially arranged multi-plate clutches. Both transmission structures are continuously active, but only one of them is connected to the engine at any one time. The fast shifts are performed by switching the clutches. Every transmission speed is assigned a conventional switching unit, as a result of which it is also possible to change directly from sixth to fourth gear, for instance.
