Additional Notes

  • Across all listed configurations of the BMW 6 Series Gran Turismo G32 (EU), the transfer case fluid capacity is uniformly 0.7 liter. A capacity at this level is typical of a compact transfer case unit designed for passenger car-based all-wheel-drive systems rather than heavy-duty truck-style transfer cases, which commonly hold several liters.
  • The 0.7 liter figure represents a service fill capacity, meaning the amount of fluid required when refilling the transfer case during a fluid change. Service fill values are generally lower than overhaul capacities, which account for fluid retained in passages and components during a full disassembly.
  • The 620dA xDrive Gran Turismo is listed in two separate power output variants, 120 kW and 140 kW, both covering the 2018-2019 and 2019-2023 model year ranges. Despite the difference in power output between these two diesel variants, the transfer case fluid capacity remains identical at 0.7 liter across all four of those rows.
  • The 640i Mild-Hybrid xDrive Gran Turismo and the 640i Mild-Hybrid xDrive Gran Turismo PF, both rated at 245 kW and spanning 2020-2023, share the same 0.7 liter transfer case capacity as the diesel variants. The PF designation typically refers to a particulate filter-equipped variant, which is an exhaust emissions distinction rather than a drivetrain difference, consistent with the identical transfer case specification.
  • All six configurations carry a normal use condition designation for the transfer case fluid specification. In fluid service contexts, a normal use condition generally refers to standard on-road driving as opposed to severe use, which typically involves towing, off-road operation, or extreme temperature exposure.
  • The consistency of the 0.7 liter capacity across both diesel and mild-hybrid petrol variants, and across different power outputs, points to a shared transfer case unit within the G32 xDrive platform regardless of engine type.
