Additional Notes
- The BMW i4 Gran Coupé G26 uses an e-transmission across all listed configurations, which refers to the gearbox unit integrated within an electric drive system rather than a conventional torque-converter or dual-clutch automatic transmission.
- Three of the four configurations — the i4 M50 (2021-2024), i4 eDrive35 (2023-2024), and i4 eDrive40 (2021-2024) — share a fixed capacity of 0.5 liter, indicating a consistent service fill volume for the e-transmission fluid in those variants.
- The i4 M50 xDrive (2024- ) carries a notably different capacity range of 0.5-1.7 liter, which is wider than the single fixed value seen in the other configurations and suggests a variable fill depending on the specific service procedure or transmission assembly involved.
- A capacity range such as 0.5-1.7 liter typically distinguishes between a partial top-up or service fill at the lower end and a more complete drain-and-refill or overhaul fill at the upper end, meaning the actual volume used depends on how much fluid is displaced during the procedure.
- All four configurations carry a normal use condition designation, meaning the listed capacities apply under standard operating circumstances rather than a severe-duty or first-change-only service scenario.
- The i4 eDrive35 has the narrowest model year span among the listed variants, appearing only in the 2023-2024 range, while both the i4 M50 and i4 eDrive40 share the broader 2021-2024 span.
