Additional Notes

  • The BMW X7 G07 front differential capacity is 0.45 liter across all configurations where a front differential is listed, covering the xDrive40i and xDrive50i variants from 2018-2019.
  • The rear differential on the X7 xDrive40i carries a capacity of 0.9 liter under normal use conditions, a figure that holds consistently across the 2018-2019 range as well as both the pre-03/2020 and post-03/2020 production splits within the 2019-2022 range.
  • The X7 xDrive50i rear differential shows two distinct capacity values within the 2018-2019 model range: one entry lists 1 liter and another lists 0.9 liter, indicating a production-date-based split even within that early period.
  • For the X7 xDrive50i covering 2019-2022, the rear differential capacity of 1 liter applies to units up to 02/2020, while the 0.9 liter figure applies to units as of 03/2020, reflecting a mid-cycle specification change tied to a specific production cutoff date.
  • The X7 M50i xDrive rear differential holds 1 liter under normal use conditions across the 2019-2022 range, placing it in the same capacity class as the early xDrive50i rear differential rather than the 0.9 liter figure seen in the xDrive40i.
  • No front differential capacity entry exists for the X7 M50i xDrive or the xDrive50i in the 2019-2022 range within the listed specifications, whereas the xDrive40i in that same range retains the 0.45 liter front differential figure tied to the as-of-03/2020 production date.
  • The 0.45 liter front differential capacity is a relatively small service fill volume, consistent with the compact housing typical of front axle differentials in all-wheel-drive systems where torque distribution demands are lower than at the rear axle.
  • The difference between the 0.9 liter and 1 liter rear differential capacities across configurations reflects a meaningful distinction in housing size or internal design between the rear axles used in the xDrive40i and certain xDrive50i and M50i applications.
