BMW X7, G07 (USA)

Additional Notes

• The BMW X7 G07 cooling system is split into two separate circuits: a high temperature cooling circuit and a low temperature cooling circuit, each carrying its own distinct capacity figure.
• The X7 xDrive40i carries a high temperature cooling circuit capacity of 12.6–13.6 liters, a range that reflects variation across assembly tolerances or fill conditions rather than a single fixed volume.
• The X7 xDrive50i high temperature cooling circuit capacity spans 12.6–15.6 liters, a notably wider range than the xDrive40i, consistent with the greater thermal demands of a V8 engine compared to the inline-six.
• Both the xDrive40i and xDrive50i share an identical low temperature cooling circuit capacity of 5.4 liters, regardless of model year within the 2018-2022 span covered by the specifications.
• The xDrive40i and xDrive50i specifications are recorded separately for vehicles produced up to 30-06-2018 and as of 01-07-2018, yet both production date brackets carry identical capacity figures for each respective variant, indicating no capacity change occurred at that production cutoff.
• The Alpina XB7, starting from 2023, carries a high temperature cooling circuit capacity of 11.2 liters, which is lower than the 12.6–15.6 liter range listed for the xDrive50i despite the XB7 being based on a high-output V8 platform.
• The Alpina XB7 low temperature cooling circuit capacity is listed at 5.0 liters, slightly below the 5.4 liters recorded for both the xDrive40i and xDrive50i configurations.
• All rows across every configuration carry a normal use condition, meaning none of the capacity figures listed are associated with a severe-duty or first-fill-only service scenario.
