Additional Notes

  • Across all listed configurations of the Audi A7, S7, RS 7, and RS 7 Performance in the 4KA body generation, the cooling system capacity is uniformly 10 liters.
  • A 10-liter cooling system capacity is consistent with a full system service fill, accounting for the radiator, engine block passages, heater core circuit, and expansion reservoir.
  • The A7 55 TFSI e quattro (270 kW), covering model years 2019-2022, shares the same 10-liter cooling system capacity as the non-hybrid A7 55 TFSI quattro (250 kW), despite the plug-in hybrid variant carrying additional electrified drivetrain components.
  • The RS 7 TFSI quattro (441 kW) for 2021-2023 and the RS 7 Performance TFSI quattro (463 kW) starting from 2023 both carry the same 10-liter cooling system capacity, even though the Performance variant produces 22 kW more output.
  • The S7 TFSI quattro (331 kW), starting from 2019, sits between the A7 and RS 7 in output rating yet aligns with the same 10-liter cooling system capacity shared across all listed variants.
  • The coolant check interval for all listed configurations is set at 20,000 miles or 24 months under normal use conditions, whichever comes first. A time-based interval of 24 months is common in modern cooling system maintenance schedules to account for coolant additive degradation independent of mileage accumulation.
