Genesis G90, RS4 (USA)

Transfer case fluid capacity & service interval

Genesis G90 and RS4 (USA) models require transfer case fluid with a capacity of 0,43 liter. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
G90 3.5 T-GDI AWD (2022- )
  • Use: Normal
  • Capacity 0,43 liter
G90 3.5 T-GDI AWD MHEV (2022- )
  • Use: Normal
  • Capacity 0,43 liter

Additional Notes

  • The Genesis G90 3.5 T-GDI AWD carries a transfer case fluid capacity of 0.43 liter, a figure that reflects a service fill volume typical of compact transfer box units found in full-size luxury sedans.
  • The mild hybrid variant, the G90 3.5 T-GDI AWD MHEV, shares the identical 0.43-liter transfer case capacity as the non-hybrid AWD configuration, indicating both use the same transfer box assembly.
  • Both configurations list the 0.43-liter capacity under normal use conditions, meaning the specified volume applies to standard operating environments rather than severe-duty cycles.
  • A capacity as low as 0.43 liter is consistent with a single-speed transfer case designed primarily for torque distribution rather than a traditional two-speed unit, where fluid volumes tend to be higher due to greater internal complexity.
