Additional Notes

  • The BMW 7 Series G70 (USA) rear differential fluid capacity is 0.9 liter across the 740i Mild-Hybrid, 740i Mild-Hybrid xDrive, 750e Plug-in Hybrid xDrive, and 760i Mild-Hybrid xDrive configurations, indicating a consistent rear differential unit size regardless of powertrain type.
  • The front differential fluid capacity on xDrive variants is 0.6 liter, which is notably smaller than the 0.9 liter rear differential capacity on the same vehicles, reflecting the typically more compact front differential housing in all-wheel-drive systems.
  • The 740i Mild-Hybrid in rear-wheel-drive form carries only a rear differential at 0.9 liter, while the xDrive version of the same engine adds a front differential at 0.6 liter, bringing the total differential fluid volume to 1.5 liters for that drivetrain.
  • The 760i Mild-Hybrid xDrive, introduced starting in 2022, shares the same front and rear differential capacities of 0.6 liter and 0.9 liter respectively as the 740i Mild-Hybrid xDrive, despite the difference in engine specification.
  • All differential fluid specifications across the G70 lineup are listed under normal use conditions, meaning the stated capacities apply to standard operating environments rather than severe-duty or first-change-only scenarios.
  • The 750e Plug-in Hybrid xDrive, starting from 2023, lists only a rear differential at 0.9 liter with no front differential entry, distinguishing its drivetrain layout from the other xDrive variants in the G70 range.
