What is the maximum wading depth of the Beijing BJ40?

According to official information, the maximum wading depth of the Beijing BJ40 is 80 cm. Common tire specifications include 265/65R17, 245/70R17, and 285/70R17. The vehicle height is 1871 mm, and it is a four-door, five-seat SUV. The maximum wading depth refers to the deepest water level a car can safely pass through. Generally, the maximum wading depth for sedans does not exceed 30 cm, while SUVs can handle slightly deeper water, though it is still advisable not to exceed 50 cm. Among common models, the GAC Trumpchi GS8 has a maximum wading depth of 30 cm, the Audi A4 has 32 cm, the Volkswagen Sagitar has 30 cm, the Land Rover Range Rover has 90 cm, the Jeep Compass has 48 cm, and the Highlander has 45 cm. SUVs clearly exceed many sedans in wading depth. Generally, depending on the depth of water and the vehicle's specifications, drivers should take different measures as follows: If the wading depth reaches the height of the exhaust pipe, it is still safe. Even if water enters the exhaust pipe, the pressure inside is sufficient to expel the water. As long as the engine is not turned off in the water, water will not flow back into the vehicle. If the wading depth reaches the height of the door frame, it becomes more dangerous. The vehicle's circuits, electronic components, and sensors are mostly located at the bottom, which could lead to short circuits, damaging critical electrical components and preventing the car from starting properly. If the wading depth reaches the height of the air intake pipe, it is extremely dangerous. Driving directly into such conditions may cause the engine to stall immediately, resulting in permanent damage or rendering the engine unusable.
I've been driving the Beijing BJ40 for several years, and it performs well off-road. The official maximum wading depth is 750 millimeters, roughly calf height. But based on my experience, don't push the limits in real-world conditions—750mm is lab-tested; in muddy or rainy terrain, water flow can reduce the effective safe depth to around 600mm. Always check the terrain before wading: avoid deep puddles, especially areas with strong currents, as wheels may lose traction. I also recommend checking the air intake location beforehand to prevent water ingestion and engine damage. Rinse the undercarriage promptly after wading to avoid rust. Safe driving should always come first—never risk it for thrills.
