MANUAL SPORT WITH MC-SHIFT FUNCTION
The MC-Shift function is the most important new feature provided by the Maserati GranTurismo S's sequential robotic gearbox: this is a new control software that reduces shift times to as little as
100 milliseconds.
In conventional electro-actuated systems the three shift phases (cut in torque/clutch opening, gear disengagement/change/engagement, clutch closing/reapplication of torque) are carried out sequentially.
On the Maserati GranTurismo S the shift phases are partially overlapped: gear disengagement takes place before the clutch is fully open and clutch closing takes place before the gear is fully engaged;
this means that the shift time, interpreted and calculated as the break in acceleration, drops to 100 ms, whilst the single gear engagement phase reduces to 40 ms.
In this mode, driving becomes a fully-involved experience: with the super-swift fast gear changes and the deep growl of the Maserati V8, providing a pure adrenalin ride.
AUTO NORMAL
When the car is driven in "everyday" style, with only gentle lateral and longitudinal acceleration, the shifting mode is tailored to maximum comfort. When the driving style becomes sportier in
Auto Normal mode, gear shifts automatically take place at higher rpm to guarantee that the maximum torque is always delivered.
AUTO SPORT
The gearbox control system still controls gear shifts automatically, but with faster changes.
Compared to Auto Normal mode, gear shifts take place at higher rpm, while the double declutch effect at downward shifts is more accentuated.
As in Manual mode, pressing the "Sport" key opens the pneumatic valves in the exhaust, allowing the engine to reach peak performance and deepening its roar.
AUTO ICE
Selected via the ICE key, this driving mode has been developed for conditions where grip is poor. Activation of the Auto ICE mode reduces the maximum torque at the wheel, prevents starts in
first gear, and only allows gear changes up to a maximum of 3.000 rpm. The mode provides maximum ease of handling even in the most slippery conditions.
