Additional Notes

  • Across all listed configurations of the BMW 8 Series Gran Coupé (G16 / F93) for the USA market, the transfer case fluid capacity is uniformly 0.7 liter, covering the 840i xDrive, M850i xDrive, M8 Gran Coupé xDrive, M8 Competition Gran Coupé xDrive, and Alpina B8 xDrive variants.
  • A 0.7 liter figure is a relatively small fill volume, consistent with a transfer case service fill rather than a full overhaul or initial factory fill, which typically accounts for residual fluid retained within the unit.
  • The M8 Gran Coupé xDrive, introduced from 2019, is the only configuration in the specifications carrying an explicit fluid change interval, set at 50,000 miles under normal use conditions.
  • The M8 Competition Gran Coupé xDrive, available from 2020, is the sole variant assigned a flexible service interval governed by the on-board maintenance system rather than a fixed mileage figure, distinguishing the service approach for the Competition trim from the standard M8 Gran Coupé xDrive despite both sharing the same 0.7 liter capacity.
  • The 840i xDrive Gran Coupé, M850i xDrive Gran Coupé, and Alpina B8 xDrive Gran Coupé all carry normal use conditions with a 0.7 liter capacity but no stated mileage interval in the specifications, unlike the M8 Gran Coupé xDrive entry.
  • The Alpina B8 xDrive Gran Coupé carries a starting year of 2021, making the transfer case specifications for that variant applicable to a narrower portion of the 2019-2021 model year window covered by the broader dataset.
