Tiptronic S, A97.50

3-Tiptronic Transmission

Tiptronic S, A97.50 - General

The 5-speed Tiptronic S available as an option for the new 911 Turbo (997) is a further development of the transmission used in the 911 Turbo (996). It was necessary to make mechanical improvements and modifications to the dynamic gearshift operations due to the higher power and torque. The Tiptronic S for the new 911 Turbo has become even sportier thanks to shortened gearshift and reaction times and the new function "Downshift before braking".

Torque Converter Lockup Clutch

The torque converter lockup clutch is also activated in 2nd to 5th gears on the new 911 Turbo with Tiptronic S. Control has been significantly enhanced compared with the 911 Turbo (996) with less slip and faster speed adaptation control, e.g. in the event of load changes. The response behaviour of the accelerator pedal commands is therefore even more spontaneous and the acceleration dynamics are increased.

Upshift Suppression, e.g. Before Curves (Fast Off)

The accelerator pedal no longer needs to be completely released in order to activate the upshift suppression function. This further increases driving dynamics, particularly on windy roads.

Downshift Before Braking (Fast Back)

The new additional function permits faster downshifting for braking operations in the case of a sporty, dynamic driving style. Immediate downshifting by one gear takes place if a change from the accelerator pedal to brake pedal occurs within 1.5 seconds. This additional function is available only for Tiptronic S on the new 911 Turbo (997) and assists the familiar function "Braking downshift".

Normal braking downshifts are performed only corresponding to the braking deceleration. This results in a time delay from the start of braking until a downshift is initiated. This delay is significantly reduced by the Fast Back function. The first downshift occurs much more spontaneously compared with a normal braking downshift. Further downshifts are performed corresponding to the normal braking downshift function.
