What is the wading depth of the BYD Tang DM?
2 Answers
The maximum wading depth of the BYD Tang DM is 170mm. The wading depth of the BYD Tang DM is determined by the height of the vehicle's chassis, which is the ground clearance listed in the model's parameter configuration table. Generally speaking, the greater the ground clearance, the higher the chassis, and the higher the safety factor when passing through waterlogged roads. Therefore, in terms of safe wading depth, the advantages of off-road vehicles and SUVs are obvious. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a benchmark when passing through waterlogged roads. If the air intake of the BYD Tang DM is below the water level during wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it will cause serious damage to the engine's mechanical structure (connecting rods, pistons, crankshaft, etc.). Therefore, the wading depth should not exceed the height of the engine's air intake. The height of the engine's air intake, and thus the maximum wading depth, can also be increased by installing a wading snorkel. If wading is unavoidable, the following safe and correct operations should be performed: Before the vehicle enters the water, the auto start-stop function must be turned off to prevent the engine from automatically restarting after stalling in the water, which could cause serious damage due to water entering the engine. Based on the passage of the vehicle ahead, assess the underwater road conditions and choose a suitable entry point. Observe the path taken by other vehicles and follow their tracks at low speed, avoiding sudden acceleration or deceleration. For roads prone to waterlogging, observe warning water level markers, trees, and other reference points such as the wheels and doors of other vehicles to judge the water depth before deciding whether to proceed. Understand your vehicle's safe wading depth. If the water depth exceeds half of the tire height or the engine's air intake, do not enter the water rashly; choose another route instead.
I've been driving SUVs for over a decade. Although the official water wading depth of the Tang DM isn't specified, judging by its ground clearance and sealing, it's approximately around 50 to 60 cm. Pay attention to the position of the air intake, which is about halfway up the wheel height. It becomes dangerous if the water depth exceeds the centerline of the tires. During heavy rain, it's best to avoid flooded areas. If you must pass through, maintain a steady speed and don't go too fast, otherwise the bow wave pushed up by the vehicle could easily flood the engine compartment. The battery pack protection in hybrid vehicles is better than in fuel-powered cars, but water damage to the electrical circuits can be very costly to repair.
