Hongqi HS7

Differential fluid capacity & service interval

Hongqi HS7 differential fluid capacity ranges from 0.39 to 1.26 liters depending on configuration. Four configurations are covered in the data.

Additional Notes

  • The Hongqi HS7 2.0T rear differential carries a capacity of 1.26 liters for the 2019-2023 model years, while the 2023 variant of the same engine configuration lists a notably reduced capacity of 0.44 liters for the same rear differential position.
  • The difference between 1.26 liters and 0.44 liters across the two 2.0T rear differential entries suggests a significant mechanical revision to the rear differential unit between those respective configurations.
  • The HS7 3.0T AWD rear differential shares the 1.26-liter capacity figure with the 2.0T rear differential across the 2019-2023 period, indicating both configurations use a rear differential of comparable fluid volume.
  • The HS7 3.0T AWD front differential is specified at 0.39 liters for 2019-2023, a smaller capacity than the rear differential on the same vehicle, which reflects the typically more compact nature of front differential housings in AWD drivetrains.
  • All four rows carry a normal use condition, meaning none of the listed capacities are associated with a severe-use or first-change-only service distinction.
  • The 3.0T AWD configuration is the only variant in the specifications that lists both a front and rear differential, with combined fluid volume across both units totaling 1.65 liters for 2019-2023.
