Additional Notes

  • The Smart forfour 453 automatic transmission fluid capacity is 1.7 liters across all listed variants, from the base 45 kW engine to the Brabus 80 kW unit.
  • A 1.7-liter fill is consistent with a transaxle-mounted dual-clutch transmission (DCT), where the fluid serves both the gear set and the clutch packs within a single compact housing.
  • All four variants specify a semi-automatic DCT transaxle configuration, meaning the fluid capacity figure reflects a combined gearbox and differential fill rather than a standalone transmission sump.
  • The 45 kW (453.041), 52 kW (453.042/043), and 66 kW (453.044/053) variants share the same 1.7-liter capacity across the 2014-2019 model years, indicating a common transmission unit regardless of power output differences within that engine range.
  • The forfour Brabus (80 kW), variant 453.062, introduced from 2016, also carries the 1.7-liter transaxle capacity, placing the highest-output variant on the same fluid volume as the lower-powered configurations.
  • All listed capacity figures apply under normal use conditions, meaning the 1.7-liter specification is not adjusted for severe-duty or extended-service scenarios in the data provided.
