Additional Notes

  • All six variants across the Fiat 1100, 103 (EU) range carry a steering box rather than a rack-and-pinion assembly, which is consistent with automotive design conventions of the 1953-1969 period.
  • The 103E and 103D variants share an identical steering box capacity of 0.17 liter, placing them slightly above the 0.16 liter figure specified for all other variants in the range.
  • The 103G/H, 103G.1, 103S, and 103P all share the same 0.16 liter steering box capacity, indicating a standardized fill volume across those configurations despite spanning different production periods from 1957 to 1969.
  • The earlier variants, the 103E (1953-1957) and 103D (1957-1962), carry a 5,000 km check interval under normal use conditions, while the later 103G.1, 103S, and 103P variants specify a 10,000 km check interval under the same conditions.
  • The doubling of the check interval from 5,000 km to 10,000 km between the earlier and later variants reflects a shift in service scheduling across the production timeline of the Fiat 1100, 103 range.
  • The 103G/H (1957-1962) shares its production period with the 103D yet already carries the 0.16 liter capacity figure and the 5,000 km interval, distinguishing it from the 103D despite overlapping years.
