BMW X6, G06 / F96 (USA)

Additional Notes

• The BMW X6 M Competition xDrive and X6 M xDrive share identical cooling system capacities across the 2019-2023 model years, with 10.8 liters in the high temperature cooling circuit and 4.5 liters in the low temperature cooling circuit.
• The split between a high temperature cooling circuit and a low temperature cooling circuit reflects a dual-loop cooling architecture, where the high temperature loop handles the engine and the low temperature loop manages components such as charge air coolers or power electronics.
• The X6 M60i xDrive Mild-Hybrid, introduced from 2023, carries a high temperature cooling circuit capacity of 11.2 liters, which is 0.4 liters greater than the figures recorded for the M Competition and M xDrive variants.
• The low temperature cooling circuit on the X6 M60i xDrive Mild-Hybrid holds 5 liters, compared to 4.5 liters on the M Competition and M xDrive, indicating a modestly larger secondary circuit in the mild-hybrid configuration.
• The X6 xDrive40i Mild-Hybrid, also from 2023, presents a range rather than a fixed value for both circuits, with the high temperature cooling circuit specified at 13.3-14.7 liters and the low temperature circuit at 5.7-6.3 liters.
• A capacity range such as 13.3-14.7 liters for the X6 xDrive40i Mild-Hybrid high temperature circuit typically reflects variation introduced by factors such as optional equipment, production sub-variants, or residual fluid retained in certain components during a service fill.
• The high temperature cooling circuit on the X6 xDrive40i Mild-Hybrid is notably larger than on any other variant in the specification set, with a minimum value of 13.3 liters exceeding the 11.2-liter figure of the M60i by more than 2 liters.
• All four configurations carry a normal use condition designation, meaning the stated capacities apply to standard operating environments without a separate severe-duty or first-fill distinction in the specifications.
