Additional Notes

  • The Maserati GranCabrio M189 Folgore carries a notably large coolant capacity of 21.8 to 22.3 liters, reflecting the thermal management demands of a fully electric powertrain, which typically requires cooling circuits for the battery pack, inverters, and electric motors in addition to any cabin conditioning loops.
  • The capacity range of 21.8 to 22.3 liters on the Folgore suggests a fill tolerance rather than a fixed volume, which is common in systems where air purging during refill can affect the final settled level.
  • The GranCabrio Modena splits cooling across two separate circuits. The main cooling circuit holds 10.5 liters, while the secondary circuit holds 5.8 liters, bringing the combined total to 16.3 liters across both loops.
  • The GranCabrio Trofeo shares the same split-circuit layout as the Modena, with an identical main circuit capacity of 10.5 liters and a secondary circuit capacity of 5.8 liters.
  • A secondary cooling circuit on a combustion-engined vehicle such as the Modena and Trofeo typically serves auxiliary components like the turbocharger system, charge air coolers, or transmission oil coolers, which require thermal regulation independent of the main engine circuit.
  • The Modena specifies a coolant check interval of every 20,000 km or 24 months under normal use conditions, applied to both the main and secondary circuits. No equivalent check interval is listed for the Trofeo circuits.
