Additional Notes
- The BAIC Senova BJ80 rear differential holds 2.8 liters of fluid, which is notably larger than the 1.5-liter front differential capacity across all three power variants — the 170 kW, 184 kW, and 206 kW configurations.
- The 1.5-liter front differential fill volume is consistent across the 170 kW, 184 kW, and 206 kW variants introduced from 2023, indicating a shared front axle assembly regardless of output rating.
- The rear differential's 2.8-liter capacity similarly remains uniform across all three power variants, suggesting a common rear axle unit is used throughout the 2023 BJ80 lineup.
- Both front and rear differential fluid changes are specified at 400,000 km or 24 months under normal use conditions, whichever comes first. The 24-month time-based interval means a fluid change can be due well before the distance threshold is reached in lower-mileage applications.
- The 400,000 km distance interval is an exceptionally long mileage figure for differential fluid service, reflecting either a high-durability fluid specification or a manufacturer assessment of low fluid degradation under normal operating conditions.
- All six rows carry a normal use condition designation, meaning the stated 400,000 km / 24-month interval applies specifically to standard operating environments rather than severe-duty cycles such as towing, off-road use, or extreme temperatures.
