  • From automatic
  • Use: Normal
  • Capacity 1,1 liter
  • RS 6 TFSI quattro (441 kW) (2019- )

Additional Notes

  • Both RS 6 TFSI quattro variants, the 441 kW introduced in 2019 and the 463 kW introduced in 2023, share an identical transfer case fluid capacity of 1.1 liters.
  • The 1.1-liter figure represents a service fill capacity drawn from an automatic transmission, as indicated by the "from automatic" notation attached to both configurations.
  • A transfer case capacity in the 1.1-liter range is characteristic of a compact, integrated unit rather than a standalone transfer case, which typically holds a larger fluid volume.
  • Both capacity values are specified under normal use conditions, meaning the intervals and fill amounts are not adjusted for severe driving cycles such as towing, off-road use, or extreme temperatures.
