Additional Notes
- The Polestar 1 (USA) carries a differential fluid capacity of 0.55 liter for the electric rear axle drive unit across the 2019-2021 model years.
- A capacity of 0.55 liter is a relatively small fill volume, consistent with the compact gear housing found in electric rear axle drive units rather than a conventional mechanical differential assembly.
- The specification is listed under normal use conditions, meaning the 0.55 liter capacity figure applies to standard operating environments rather than severe-duty or high-stress driving cycles.
