Additional Notes
- All three configurations listed for the Audi Quattro (EU) share an identical cooling system capacity of 9.3 liters, covering the 147 kW variant from 1980-1989, the 162 kW variant from 1989-1991, and the Sport quattro from 1983-1987.
- A 9.3-liter cooling system capacity is a relatively large figure for a passenger car of that era, reflecting the demands of a turbocharged engine architecture across all listed variants.
- The 147 kW and 162 kW designations represent two distinct power outputs within the Quattro lineup, yet both share the same 9.3-liter cooling system fill specification, indicating no capacity difference between the two engine states.
- The Sport quattro, produced from 1983-1987, carries the same 9.3-liter cooling system capacity despite being a separate and shorter-wheelbase model variant within the Quattro family.
- All capacity figures across the three rows are listed under normal use conditions, meaning the 9.3-liter specification applies to standard operating environments rather than severe or competition-oriented service definitions.
- The 9.3-liter figure represents a full cooling system capacity, which typically accounts for the total volume of coolant held across the radiator, engine block, cylinder head passages, heater core, and expansion reservoir combined.
