Sport Chrono Function

Sport Chrono Function







The Sport Chrono package is offered as an option on the new 911 Carrera and 911 Carrera S. This option provides for an even more sporty driving experience, particularly when using vehicle on race circuits.

Shift Gate "D"

Pressing the Sport Chrono switch when the gear shift lever is in shift gate "D" boosts the basic gear-changing map. This raises the engine speeds for gear-changing and renders gear-changing sportier by shortening the shifting times. The reduction in shifting times results from faster filling of the clutches with oil (response time) and a higher oil pressure level when performing the shift operation. These measures lend the shift operations a more dynamic and noticeably sportier character. The shift points are then adjusted between this boosted basic gear-changing map and the sport gear-changing map according to the present driving style. System downshifts are initiated at lower acceleration and higher speeds (in comparison with when the Sport Chrono switch is off) to increase agility.

Shift Gate "M"

When the Sport Chrono switch is pressed with the gear shift lever in shift gate "M", no automatic upshift will be effected when the engine speed limit is reached. This function allows the driver to operate the engine in the range of the engine speed limiter for the first time, even on vehicles with Tiptronic. This reinforces the sporty character of the Sport Chrono function.

Upshift suppression is only active in the manual shift gate; it is not active in the "D" shift gate or in one-touch mode for temporary override in shift gate "D". Upshift when the engine speed limit is reached can be overridden via the kickdown function. When the engine speed limit is reached in M gate during an passing manoeuvre, for example, upshift can be executed even without pressing the switches on the steering wheel, by means of a kickdown. This measure boosts the acceleration potential and speeds up the passing process in this situation. This is the only function whereby a kickdown results in an upshift rather than a downshift.
