What is the maximum wading depth of the BYD Tang DM?

According to official information, the maximum wading depth of the BYD Tang DM is 170mm. Common tire specifications include 245/45R20, 255/50R20, and 265/40R22. The vehicle has a length of 4870mm, a curb weight of 2250-2455kg, and is a 5-door, 7-seat SUV. The maximum wading depth refers to the deepest water level a vehicle can safely pass through. Generally, the maximum wading depth for sedans does not exceed 30cm, while SUVs can handle slightly deeper water, though it's still advisable not to exceed 50cm. Among common models, the GAC Trumpchi GS8 has a maximum wading depth of 30cm, the Audi A4 has 32cm, the Volkswagen Sagitar has 30cm, the Land Rover Range Rover has 90cm, the Jeep Compass has 48cm, and the Highlander has 45cm. SUVs clearly outperform sedans in terms of maximum wading depth. Generally, when driving through water, vehicle owners should take different measures depending on the water depth and the vehicle's characteristics, as follows: If the water reaches the exhaust pipe height, 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, preventing backflow into the vehicle. If the water reaches the door frame height, it becomes more dangerous. The vehicle's circuits, electronic components, and sensors are mostly located at the bottom, risking short circuits and damage to critical electrical components, which may prevent the car from starting. If the water reaches the air intake height, it is extremely dangerous. Driving directly into such conditions can cause the engine to stall immediately, leading to permanent damage or rendering the engine unusable.
The BYD Tang DM has a maximum wading depth of approximately 450mm, which is just under half a meter. When I drive this car to and from work, I often encounter rainy conditions and water accumulation. It handles general urban puddles quite well, as the engine air intake is designed relatively high, and the hybrid system's battery has waterproof protection, reducing the risk of water ingress and malfunctions. However, remember not to test deep water areas—places with strong currents or heavy mud pose greater risks. It's best to check the vehicle manual or consult a mechanic to confirm the exact specifications to avoid engine damage. I once drove through shallow floodwaters during heavy rain, and it performed steadily, but I stopped when the depth exceeded 300mm to prevent issues. In short, choosing an SUV is about this practical safety feature—just maintain a slow speed when passing through water.
The BYD Tang DM has a wading depth of around 450mm, which I understand stems from its engine air intake height and battery protection standards. Compared to other vehicles like conventional SUVs with 400mm, the Tang DM as a plug-in hybrid has an advantage—its electric components are well-sealed and less prone to water ingress, while the pure engine has a lower risk of water damage. I've discussed this topic on car enthusiast forums, and the Tang's structure allows it to handle low water levels well, but excessively high water levels may cause short circuits or corrode components. It's advised not to rely solely on the numbers; when driving, observe the tire submersion level. If the water level approaches the engine hood, don't take the risk, and regular inspection of the underbody seals is also crucial. This car offers more peace of mind in urban flood-prone areas, making it a thoughtful design.
