Additional Notes

  • The Audi Q7 3.0 T quattro (245 kW), covering model years 2016-2018, carries a notably larger cooling system capacity of 15 liters compared to the 10-liter figure shared by all other configurations in the lineup. A higher coolant volume in a larger-displacement turbocharged engine reflects the greater thermal load generated and the additional circuit volume needed to manage heat across a more complex engine architecture.
  • Every configuration except the 3.0 T quattro (245 kW) specifies a 10-liter cooling system capacity. This figure applies to four-cylinder turbocharged variants, the 55 TFSI six-cylinder variants, and the SQ7 4.0 TFSI quattro (373 kW), indicating that cooling system volume does not scale directly with engine output across all configurations.
  • The SQ7 4.0 TFSI quattro (373 kW), rated at 373 kW, shares the same 10-liter cooling system capacity and 20,000-mile/24-month check interval as the lower-output Q7 variants. This suggests the 4.0-liter V8 engine uses a cooling circuit engineered to similar total volume despite its substantially higher power output.
  • All configurations across the 2016-2022 range share a uniform coolant check interval of 20,000 miles or 24 months under normal use conditions. The dual-format interval means the check is due at whichever threshold is reached first, whether mileage or time.
  • The Q7 45 TFSI quattro at 185 kW spans three separate specification entries covering 2018-2020, 2020-2022, and a starting year of 2022 at a revised 195 kW output. The 10-liter capacity and 20,000-mile/24-month check interval remain consistent across all three entries despite the power increase in the later variant.
  • The Q7 55 TFSI quattro underwent a power output revision between its two specification entries, moving from 245 kW in 2018-2019 to 250 kW from 2019 onward. Both entries retain the same 10-liter cooling system capacity and identical check interval, indicating the minor output increase did not alter cooling system volume requirements.
  • The early Q7 3.0 T quattro (245 kW) from 2016-2018 and the later Q7 55 TFSI quattro (245 kW) from 2018-2019 share the same power rating but differ in cooling system capacity, with the former requiring 15 liters and the latter 10 liters. This difference reflects distinct engine generations and cooling circuit designs rather than output alone.
