Additional Notes

  • All six Smart forfour 454 configurations covered in these specifications share an identical automatic transmission fluid capacity of 1.7 liters, applying to both petrol and diesel variants across the 2004-2006 model years.
  • The 1.7-liter figure represents a transaxle fill capacity, meaning the transmission and final drive are housed in a single combined unit rather than separate assemblies, which is a common layout in rear-engined or compact vehicle platforms.
  • Each row is designated as a semi-automatic transaxle, a type that uses automated clutch actuation and gear selection without a conventional torque converter, distinguishing the fluid requirements from those of a traditional fully hydraulic automatic transmission.
  • The capacity value of 1.7 liters applies under normal use conditions across all listed variants, including the diesel-powered 454.000 (50 kW) and 454.001 (70 kW) configurations, which share the same transaxle fluid volume as the petrol models.
  • The Smart forfour 1.5 Brabus SB3, producing 90 kW and covering the 2004-2005 period under chassis code 454.032, carries the same 1.7-liter transaxle capacity as the standard 1.5-liter 454.032 variant, despite the significant difference in power output between the two.
  • The 1.1-liter (454.030) and 1.3-liter (454.031) petrol variants, representing the lower displacement end of the forfour range, also share the uniform 1.7-liter transaxle capacity, indicating a common transmission unit across multiple engine displacements in the 454 series.
