Additional Notes

  • The BMW 5 Series G60/G90/G91 cooling system specifications cover two separate circuits across all listed configurations: a high temperature cooling circuit and a low temperature cooling circuit, each with its own distinct capacity figure.
  • The high temperature cooling circuit handles the primary engine thermal management, while the low temperature cooling circuit serves auxiliary heat loads such as charge air cooling and, in electrified variants, power electronics and battery thermal conditioning.
  • The 530i Mild-Hybrid and 530i Mild-Hybrid xDrive share identical cooling system capacities, with 10.5 liters in the high temperature circuit and 4.5 liters in the low temperature circuit.
  • The 540i Mild-Hybrid xDrive carries a larger high temperature circuit capacity of 12.6 liters and a low temperature circuit capacity of 5.4 liters, reflecting a greater total coolant volume compared to the 530i variants.
  • The 550e Plug-in Hybrid xDrive matches the 540i Mild-Hybrid xDrive at 12.6 liters for the high temperature circuit and 5.4 liters for the low temperature circuit, despite the addition of a plug-in hybrid powertrain.
  • The M5 Plug-in Hybrid xDrive carries the largest cooling system capacities among all listed configurations, with 13.5 liters in the high temperature circuit and 6.6 liters in the low temperature circuit, consistent with the thermal demands of a high-output performance powertrain combined with plug-in hybrid hardware.
  • All five configurations list a normal use condition, meaning the specified capacities apply to standard operating environments without a separate severe-duty or first-fill distinction noted in the specifications.
