Additional Notes

  • The BMW i3 I01 (EU) e-transmission fluid capacity is 0.5 liter across all listed configurations, a notably small volume that reflects the compact, single-speed reduction gear unit used in battery electric drivetrains rather than a conventional multi-speed automatic gearbox.
  • Both the i3 BEV and i3 REX (125 kW) variants share the identical 0.5 liter capacity figure, indicating no differentiation in transmission fluid volume between the pure battery-electric and the range-extender-equipped configurations.
  • The 2013-2019 i3 BEV and the 2019 onward i3 BEV carry the same 0.5 liter e-transmission capacity, meaning no change in fluid volume was introduced at the 2019 model boundary for the BEV variant.
  • The i3 REX (125 kW) follows the same pattern, with the 2013-2019 and 2019 onward specifications both listing 0.5 liter, confirming consistency across the production split for the range-extender model as well.
  • All four rows are designated under normal use conditions, meaning the 0.5 liter capacity figure applies specifically to standard operating environments rather than severe-duty or first-change-only scenarios.
