What is the wading depth of the BYD Song Plus DMI?
4 Answers
The wading depth of the BYD Song Plus DMI is 150mm. The safe wading depth is the distance of the vehicle's ground clearance. If the water depth exceeds two-thirds of the wheel height after entering the water, it exceeds the safe range, and water may enter the interior. If the water depth exceeds the front bumper or approaches the front grille position, it will directly cause water to enter the engine, damaging the vehicle. If the vehicle stalls in deep water, water entering the exhaust pipe and flowing back into the engine may severely damage the vehicle. There are three scenarios of water submersion: water level above the exhaust pipe but below half-wheel height, water level exactly at half-wheel height, and water level above half-wheel height. Generally, water reaching exactly half-wheel height will affect the car. Below is the detailed explanation: 1. Water level above the exhaust pipe: If the water only covers the exhaust pipe, promptly moving the car away is sufficient. Water covering the exhaust pipe won't be sucked back into the engine, and engine stalling is mainly due to water entering the engine intake system, unrelated to the exhaust pipe being submerged. 2. Water level exactly at half-wheel height: If the water is exactly at half-wheel height, the car usually won't leak; however, if soaked for a long time with aging seals, leakage may occur. In such cases, drive the car to a 4S shop, disassemble the interior, clean, and dry it. 3. Water level above half-wheel height: If the water exceeds half-wheel height, the engine may take in water, and the interior may also leak. Never start the engine in this situation to avoid burning out the engine or interior electronics. Moreover, if the car is submerged, damage caused by ignition won't be covered by insurance.
As a veteran driver with over a decade of experience, I believe the wading depth of the BYD Song Plus DM-i is approximately 30 to 40 centimeters. This depth refers to the safe level for crossing small streams or rainwater, primarily dependent on the waterproof design of the battery and engine system. Hybrid vehicles excel in protecting electronic components, but it's still important not to take unnecessary risks. I've encountered situations with heavy rain and water accumulation while driving, and I recommend keeping the speed below 10 kilometers per hour to prevent water from splashing into the cabin or affecting the exhaust system. Regular maintenance should also pay attention to tire pressure and chassis sealing to ensure no short circuits or corrosion occur during water exposure. Safe driving is paramount—if the water exceeds this depth, it's wise to avoid forcing your way through and instead find a dry spot to park and wait for assistance. Remember, your car is your partner; protecting it means protecting yourself.
From my observation, the BYD Song Plus DM-i hybrid version has a wading capability of approximately 30 centimeters, which benefits from its higher ground clearance and optimized electrical layout. Compared to gasoline-powered vehicles, the battery pack placement in hybrid models may reduce risks during water crossings, but if the water level submerges the hood, it could trigger malfunctions. I believe it's essential to navigate through waterlogged areas slowly in daily driving, using the wheel center height as a reference line. In case of driving into a deep water pit, immediately turn off the air conditioning system to prevent water ingress, and then check for any issues with the brakes and sensors. Tips for extending the vehicle's lifespan include regular inspections of tire wear and air filters, which can enhance wading performance. Overall, the car is designed safely, but drivers should also maintain a sense of caution.
My experience is that the BYD Song Plus DM-i has a wading depth of about 30cm, which reminds me of driving through heavy rain when picking up my kids. As a parent, safety comes first—you have to be extra cautious when driving through flooded roads, especially since water damage to the hybrid system's battery could lead to costly repairs. A vehicle's wading capability depends on its weight and underbody protection, so I always remind myself to drive slowly through puddles and avoid sudden acceleration to prevent splashing. It's best to get a full inspection before the rainy season to ensure window seals and air intakes are clean. A practical tip is to estimate water depth by ensuring it doesn’t exceed half the tire height. If flooding is severe, don’t hesitate to call for help—protecting your family is more important than anything. Keeping your car well-maintained ensures peace of mind on the road.
