At what water level will a sedan's engine take in water?

Theoretically, as long as the water does not submerge the air intake, the engine will not be affected. However, there are too many unpredictable factors. When vehicles pass by, waves may splash into the air intake. Additionally, it is essential to drive slowly, and the underwater environment is unknown, so caution is necessary. If the engine stalls while wading through water, never attempt to restart it. Exhaust pipe height: Safe wading height: The pressure generated by the engine during exhaust is substantial enough to expel any water that might backflow into the exhaust pipe. Therefore, as long as the engine does not stall and the vehicle maintains sufficient and stable power, water backflow into the exhaust pipe can be prevented, allowing safe passage through the water. Door sill height: This may cause water to enter the cabin. Modern cars are equipped with numerous electronic components and sensors, and if water floods the interior, it can be quite troublesome. Air intake height: Maximum wading height: The height of the engine's air intake is the most critical indicator of a vehicle's wading capability. If water enters the air intake, it will cause the engine to stall, and in severe cases, water may be sucked into the engine, leading to permanent damage. Therefore, driving is absolutely not advisable if the water reaches this level.
