Additional Notes

  • Every xDrive variant of the BMW 8 Series Coupé (G15 / F92) covered in these specifications carries a transfer case fluid capacity of 0.7 liter, indicating a service fill volume rather than a full overhaul or dry-fill quantity.
  • The M8 xDrive Coupé (2019- ) is the only configuration in these specifications that lists an explicit fluid change interval, set at 50,000 miles under normal use conditions.
  • The M8 Competition Coupé xDrive (2020- ) is assigned a flexible interval tied to the on-board maintenance system rather than a fixed mileage figure, meaning the vehicle's own monitoring determines when a transfer case fluid change is due.
  • The 840i xDrive Coupé (2019- ) and the M850i xDrive Coupé share the same 0.7-liter transfer case capacity as the M8 variants, despite differences in engine output across those configurations.
  • The M850i xDrive Coupé appears under two separate specification entries: one covering 2018-2019 and another starting from 2019, both recording a 0.7-liter transfer case capacity under normal use, with no change interval stated in either entry.
  • The 840i xDrive Coupé (2019- ) lists no fluid change interval alongside its 0.7-liter capacity under normal use, which differs from the M8 xDrive Coupé entry that does carry a stated 50,000-mile interval under the same use condition.
