Automatic transmission fluid capacity & service interval

BMW i7, G70 (USA) models utilize automatic transmission fluid with a capacity range of 0,5 to 2,1 liters. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

  • Code: HEAT 220MF, 220LR, 220 XLR 1/1
  • i7 xDrive60 (2022- )
  • Electric drive
  • Use: Normal
  • Capacity 0,5-2,1 liter
  • Code: HEAT 220MF, 220LR, 220 XLR 1/1

Additional Notes

  • All three variants in the BMW i7 G70 lineup use an e-transmission, which is an electrically driven transmission unit rather than a conventional torque-converter or dual-clutch automatic gearbox.
  • The i7 xDrive60 carries a starting year of 2022, while the i7 eDrive50 and i7 M70 xDrive both carry a starting year of 2023, placing the xDrive60 as the earlier entry in the G70 range.
  • Each of the three variants shares an identical fluid capacity range of 0.5 to 2.1 liters under normal use conditions, indicating a consistent transmission architecture across the lineup despite differences in drivetrain configuration.
  • A capacity range of 0.5 to 2.1 liters, rather than a fixed single value, is characteristic of a service fill specification, where the actual amount added depends on how much fluid remains in the unit after draining, as opposed to a dry-fill or overhaul figure that would represent total system volume.
  • The relatively low upper bound of 2.1 liters reflects the compact fluid volume typical of e-transmission units, which generally require less fluid than conventional multi-speed automatic transmissions designed for combustion engines.
  • All three variants list normal as the sole use condition, meaning the 0.5 to 2.1 liter service fill range applies specifically to standard operating conditions rather than a severe-duty or first-change interval.
