According to official information, the maximum wading depth of the Hongqi H5 is 15 cm. Common tire specifications include 225/45R19 and 225/55R17, with a body length of 4945 mm. The car is equipped with a 6-speed automatic transmission and a 7-speed wet dual-clutch transmission, featuring a 4-door, 5-seat sedan body structure. The maximum wading depth refers to the deepest water a vehicle can safely pass through. Generally, the maximum wading depth for sedans does not exceed 30 cm, while SUVs have a higher maximum wading depth, 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. The maximum wading depth of SUVs is significantly higher than that of sedans. Generally, when a vehicle is wading through water, different measures should be taken by the owner depending on the depth and the vehicle's characteristics, as follows: If the wading depth reaches the height of the exhaust pipe, it is relatively safe. Even if water enters the exhaust pipe, the pressure inside is sufficient to expel it. 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 concentrated at the bottom, which may lead to circuit disconnection, damaging critical electrical components and preventing the car from starting normally. If the wading depth reaches the height of the intake pipe, it is extremely dangerous. Driving directly into such conditions may cause the vehicle to stall immediately, resulting in permanent engine damage or rendering it unusable.

I've been driving for many years. The official wading depth of the Hongqi H5 is about 450 millimeters, equivalent to half the height of the wheel. Exceeding this depth may cause water to backflow into the air intake, leading to engine flooding and major repairs. I've personally seen a friend's car break down because of this, costing tens of thousands to fix. When wading through water, always pass slowly, avoid sudden acceleration or gear changes, and let the water flow smoothly. If the water depth is uncertain, get out and measure it with a stick before deciding. Before heading out in the rain, check the weather forecast to avoid flooded areas. After driving through water, inspect the chassis and electrical circuits for moisture. Developing a habit of regular maintenance can reduce risks. Safe driving is true wisdom.

I just bought a Hongqi H5 and am particularly concerned about wading safety, with a maximum depth of around 450mm. I'm afraid that water above the wheel hubs might flood and damage the car, so I avoid puddles on the road every time it rains. If I have to wade through water, I check the road conditions in advance and maintain a steady speed when crossing puddles, not too fast. If the water is too deep, even the headlights or electrical circuits might short out, and it would be troublesome if they don't light up. After wading, I make it a habit to get a full inspection of the chassis seals at the shop. For beginners, I recommend installing a wading detector accessory—a small investment to protect your big car. Don't take risks; driving cautiously saves you trouble and worry.

The Hongqi H5 should not wade through water exceeding 450mm in height, which is roughly half the height of its wheels. Sedans have lower chassis and are prone to water ingress and stalling. Drive slowly and avoid shifting gears when wading to prevent water from entering the engine. It's best to avoid puddles while driving to save trouble. If a puddle is too deep, choose another route. Regular inspections and maintenance can prevent potential issues.
