The outstanding feature of the eight-speed Tiptronic S is a particularly wide ratio spread. First gear is designed for optimum acceleration when pulling away and greater performance when tackling ascents and towing loads in off-road terrain. Top speed is reached in 6th gear (in 7th gear on the Cayenne Diesel). The remaining upper gears are used to lower the revs at high speed, thereby enhancing fuel economy and occupant comfort. On the motorway in particular, driving at low revs will significantly reduce the noise level inside the vehicle.
In automatic mode, the driver can influence gearshifts on the Tiptronic S using the throttle and brakes alone. Tiptronic S automatically adapts the gearshift points for performance driving – equally, if a more defensive driving style is detected, the system selects a gearshift point that offers maximum fuel economy. Under heavy braking, Tiptronic S shifts down to maximise engine braking.
An electric pump is used to maintain the required pressure of the transmission fluid, e.g. to transmit high levels of torque at lower engine speeds.
The standard sports steering wheel in conjunction with Tiptronic S has two ergonomic switches for manual gear changes. One press forward with the thumb and Tiptronic S shifts up. One pull backwards with the index finger and Tiptronic S shifts down. Either the right or left-hand switch can be used. The result: an even more dynamic response when changing gear.
Standard on the Cayenne Diesel, Cayenne S, Cayenne S Hybrid, Cayenne GTS and Cayenne Turbo. Optional for the Cayenne.
