Additional Notes
- The BMW iX3 G08 cooling system capacity is listed at 19.6 liters across both the standard iX3 and the iX3 M Sport configurations, indicating a full system fill volume rather than a partial or top-off quantity.
- A 19.6-liter cooling system capacity is notably large relative to many conventional internal combustion vehicles, which reflects the thermal management demands of an electric drivetrain that must regulate battery pack temperature, power electronics, and cabin climate simultaneously.
- The standard iX3 carries the 19.6-liter cooling system capacity from 2020-2024, while the iX3 M Sport shares the same figure across its 2021-2024 model year range.
- Both configurations are specified under a normal use condition, meaning the 19.6-liter capacity value applies to standard operating environments rather than severe-duty or first-fill-only scenarios.
