Maserati GranTurismo, M189

Differential fluid capacity & service interval

Maserati GranTurismo and M189 models utilize differential fluid with a capacity range of 0,48 to 1,35 liters. The data covers 4 configurations.

Additional Notes

  • The Maserati GranTurismo M189 carries two separate differential assemblies, front and rear, each with its own fluid capacity specification.
  • The front differential capacity is 0.48 liter across both the Modena and Trofeo variants, reflecting the relatively compact housing typical of a front drive unit in an all-wheel-drive layout.
  • The rear differential holds 1.35 liters, nearly three times the front unit's volume, which is consistent with a larger rear housing that handles the primary torque distribution load in a rear-biased drivetrain.
  • Both the Modena and Trofeo share identical front and rear differential capacities, meaning trim level alone does not differentiate fluid fill quantities in either position.
  • All four rows carry a normal use condition, meaning the stated capacities apply to standard operating circumstances rather than a separate severe-duty or first-fill scenario.
  • The 0.48-liter front differential figure represents a service fill quantity, indicating the amount of fluid required during a routine drain-and-refill procedure under normal use conditions.
  • A combined differential fluid volume of 1.83 liters per vehicle, when totaling front and rear, reflects the dual-differential architecture introduced with the 2023 GranTurismo M189 generation.
