Additional Notes

  • The rear electric drive differential on the Subaru Solterra (EU) 160 kW AWD holds 3.1 liters of fluid, a figure that applies equally under both normal and severe use conditions.
  • Under normal use, the differential fluid interval is a check at 48 months or 60,000 km, with no separate change interval specified for that condition.
  • Under severe use, the check interval shortens to 36 months or 45,000 km, and a dedicated change interval is added at 72 months or 90,000 km, reflecting the additional demands placed on the fluid in harder operating conditions.
  • The distinction between a check-only schedule under normal use and a check-plus-change schedule under severe use means the total service obligation for the rear differential differs meaningfully depending on operating conditions, even though the fluid capacity remains identical at 3.1 liters.
  • A 3.1-liter capacity for a rear electric drive differential is a moderately sized fill, consistent with a dedicated rear drive unit rather than a shared transaxle assembly, where the differential and motor share a common fluid sump.
