Additional Notes
- The BMW 8 Series Gran Coupé G16 840d Mild-Hybrid xDrive (250 kW) operates two separate cooling circuits: a high temperature cooling circuit with a capacity of 10.2 liters and a low temperature cooling circuit with a capacity of 1.3 liters.
- The split cooling architecture in the 840d Mild-Hybrid xDrive reflects the thermal management demands of mild-hybrid drivetrains, where the low temperature circuit typically handles power electronics or ancillary components that require cooler operating temperatures than the main engine.
- The 840d xDrive Gran Coupé DPF (235 kW), covering model years 2019-2020, carries a single cooling system capacity of 9.5 liters, which is a straightforward service fill figure for the entire circuit.
- Comparing the 235 kW and 250 kW 840d variants, the high temperature circuit alone in the mild-hybrid version holds 10.2 liters, representing an increase of 0.7 liters over the non-hybrid engine's total 9.5-liter capacity.
- The Alpina B8 xDrive Gran Coupé lists a coolant capacity range of 8.75 to 10 liters, indicating that the exact fill volume can vary depending on the specific configuration or assembly state of the vehicle at the time of service.
- All three configurations carry a normal use condition designation for coolant service, meaning the listed capacities apply under standard operating and maintenance circumstances rather than severe-duty cycles.
