Additional Notes
- All four configurations listed for the Hongqi H9 rear differential share an identical service fill capacity of 1.12 liters, indicating a compact rear differential unit consistent across the model range from 2023 and 2024 starting years.
- The 1.12-liter figure represents a service fill capacity, meaning the volume of fluid required during a standard drain-and-refill procedure rather than a complete overhaul or dry-fill scenario.
- The H9+ 3.0T carries a starting year of 2023, while the 2.0T, 2.5T, and 3.0T variants each carry a starting year of 2024, placing the H9+ as the earlier entry point within the listed specifications.
- Despite the variation in engine displacement across the 2.0T, 2.5T, 3.0T, and H9+ 3.0T configurations, the rear differential capacity remains uniform at 1.12 liters, suggesting a shared rear differential housing regardless of powertrain output.
- All rows are designated under normal use conditions, meaning the 1.12-liter capacity figure applies specifically to standard operating environments rather than severe-duty or first-change scenarios.
