Additional Notes

  • All three BMW iX configurations covered here — the M60, xDrive40, and xDrive50 — share an identical cooling system capacity of 25 liters.
  • A 25-liter coolant capacity is notably large compared to conventional internal combustion vehicles, reflecting the thermal management demands of high-voltage electric drivetrains, which require cooling for battery packs, power electronics, and electric motors in addition to cabin climate systems.
  • The capacity figure of 25 liters applies to the cooling system as a whole, meaning a full drain and refill during an overhaul or system flush would require the entire 25-liter volume, whereas a partial service may involve a smaller quantity depending on how much fluid is retained in the system.
  • All three configurations carry a normal use condition designation, meaning the 25-liter capacity specification is associated with standard operating conditions rather than a severe-duty or first-change-only service scenario.
  • The iX xDrive40 and iX xDrive50 share the same 25-liter cooling system capacity starting from the 2021 model year, while the iX M60 carries the same figure but from the 2022 model year onward.
