What is the standard wading depth for cars?

[LeXavier]

Different vehicle models have varying wading depth standards. Sedans typically have a wading depth of 20-30 cm, SUVs range from 30-60 cm, while rugged off-road vehicles can achieve 70-100 cm. As long as the water level does not exceed the height of the engine air intake, there should be no major issues. The potential impacts of driving through water are as follows: 1. Crankshaft connecting rod deformation and damage: When a mixture of water and air enters the engine through the intake, the connecting rod may deform under the influence of water because gases are compressible but liquids are not. If the driver attempts to start the car at this point, the tremendous counterforce will cause the bent connecting rod to rub against the cylinder block, resulting in irreversible damage. 2. Interior mold growth: If water enters the cabin, improperly treated carpets and upholstery that have been soaked may develop mold and odors. 3. Transmission rust: Water mixing with transmission oil can accelerate wear and, in severe cases, lead to extensive rusting of the transmission.
