Additional Notes

  • The front differential across the M8 Gran Coupé xDrive, M8 Competition Gran Coupé xDrive, M850i xDrive Gran Coupé, and Alpina B8 xDrive Gran Coupé all share a 0.6 liter capacity, with the specification noted as applying to units produced as of 03/2020 for the M8 and M850i variants.
  • The rear differential capacity across all listed configurations is 1 liter, a figure that applies uniformly regardless of trim level or use condition.
  • The BMW 8 Series Gran Coupé M8 Gran Coupé xDrive rear differential carries a first change interval of 1,200 miles, a short initial service interval associated with break-in fluid that accumulates metal particles during early component wear.
  • Following the first change, the M8 Gran Coupé xDrive rear differential is serviced at 50,000 miles under normal use conditions, representing the standard ongoing interval for that unit.
  • The M8 Competition Gran Coupé xDrive rear differential shares the same 1,200-mile first change interval and 1 liter capacity as the non-Competition M8 Gran Coupé xDrive, with both intervals tied to the same 1 liter fill.
  • The M8 Competition Gran Coupé xDrive rear differential also carries a flexible interval of 50,000 miles governed by the on-board maintenance system, which adjusts service timing based on monitored operating conditions rather than a fixed mileage schedule alone.
  • The M850i xDrive Gran Coupé rear differential is listed only under normal use with a 1 liter capacity and no change interval specified, in contrast to the M8 variants that carry both first-change and subsequent interval entries.
  • The Alpina B8 xDrive Gran Coupé, with a starting year of 2021, lists both front and rear differential capacities at 0.6 liter and 1 liter respectively under normal use, with no change interval figures included in the specification.
