Additional Notes
- All four variants listed — the i4 M50, i4 M50 xDrive, i4 eDrive35, and i4 eDrive40 — share an identical cooling system capacity of 25 liters under normal use conditions.
- A 25-liter cooling system capacity is notably large compared to conventional internal combustion vehicles, which reflects the thermal management demands of electric drivetrains, where battery packs, power electronics, and electric motors each require dedicated cooling circuits.
- The BMW i4 Gran Coupé G26 cooling system capacity of 25 liters applies as a full system fill figure, meaning the value accounts for the total fluid volume across all interconnected cooling loops rather than a single circuit.
- The i4 M50 carries the 25-liter specification across the 2021-2024 model years, while the i4 M50 xDrive carries the same capacity from its 2024 introduction onward, indicating no divergence in cooling system volume between the two M50 configurations despite the xDrive's additional drivetrain hardware.
- The i4 eDrive35, introduced for 2023, shares the 25-liter capacity with the longer-running i4 eDrive40, which has carried the same figure since 2021, showing no variation in cooling system volume between the single-motor eDrive variants.
