Additional Notes

  • A 25-liter cooling system capacity is notably large for a passenger car and reflects the thermal demands of a high-displacement, naturally aspirated V10 engine. Larger coolant volumes help stabilize operating temperatures under sustained high-load conditions by increasing the thermal mass of the system.
  • The Audi R8 4S (USA) cooling system capacity of 25 liters is consistent across all six listed configurations, spanning the 397 kW, 419 kW, 449 kW, and 456 kW output variants of the 5.2 FSI V10.
  • The RWS (Rear-Wheel Series) variant rated at 397 kW shares the same 25-liter cooling system capacity as the quattro all-wheel-drive variant at the same power output, indicating no cooling system differentiation between the two drivetrain configurations.
  • The check interval of 20,000 miles or 24 months applies under normal use conditions across all listed configurations. A coolant check interval is distinct from a coolant change interval and involves inspecting concentration, pH, and condition rather than replacing the fluid.
  • The 456 kW Performance quattro variant covers the 2018-2019 period, while the 449 kW Performance quattro variant spans 2019-2022, with both sharing identical cooling system capacity and check interval specifications despite the difference in rated output.
  • The 419 kW quattro variant covers 2018-2022, overlapping with the 456 kW and 449 kW Performance variants in certain model years. All three carry the same 25-liter capacity and 20,000-mile or 24-month check schedule under normal use conditions.
