Additional Notes

  • The BMW i3 I01 (USA) e-transmission carries a fluid capacity of 0.5 liter across all configurations listed, which is a notably small volume consistent with the compact, single-speed reduction gearboxes found in battery electric and range-extender electric drivetrains.
  • A 0.5-liter capacity figure typically represents a service fill level rather than a full overhaul or dry fill quantity, meaning the transmission already retains residual fluid during a standard fluid exchange.
  • All rows specify normal use conditions, meaning the listed 0.5-liter capacity applies to routine service rather than severe-duty or first-change intervals.
  • The i3 BEV e-transmission shares the same 0.5-liter capacity as the i3 REX variants, indicating no difference in fluid volume between the pure battery-electric and range-extender configurations despite their differing powertrain layouts.
  • The i3 REX (125 kW) spans multiple year groupings, including 2013-2015, 2015-2019, and a range starting in 2019, yet the e-transmission fluid capacity remains at 0.5 liter across all of those groupings without variation.
