What is the maximum wading depth of the BMW 320?
2 Answers
According to official information, the maximum wading depth of the BMW 320 is 250mm. Common tire specifications are 225/45R18, with a body length of 4829mm or 4719mm, and it is a 4-door, 5-seat sedan. The maximum wading depth refers to the deepest water level a car can safely pass through. Generally, the maximum wading depth for sedans does not exceed 30 cm, while SUVs have a higher wading depth, but it is still best not to exceed 50 cm. Among common models, the GAC Trumpchi GS8 has a maximum wading depth of 30 cm, the Audi A4 has a maximum wading depth of 32 cm, the Volkswagen Sagitar has a maximum wading depth of 30 cm, the Land Rover Range Rover has a maximum wading depth of 90 cm, the Jeep Compass has a maximum wading depth of 48 cm, and the Highlander has a maximum wading depth of 45 cm. The maximum wading depth of SUVs is significantly higher than that of sedans. Generally, when driving through water, vehicle owners should take different measures depending on the depth of the water and the characteristics of the car itself, as detailed below: If the water depth reaches the height of the exhaust pipe, it is relatively safe. Even if water enters the exhaust pipe, the pressure inside is sufficient to expel the water. As long as the engine is not turned off in the water, water will not flow back into the vehicle. If the water depth reaches the height of the door frame, it becomes more dangerous. The vehicle's circuits, electronic components, and sensors are mostly located at the bottom of the car, which could lead to short circuits and damage critical electrical components, preventing the car from starting normally. If the water depth reaches the height of the air intake pipe, it is extremely dangerous. Driving directly into such conditions could cause the engine to stall immediately, leading to permanent damage or rendering the engine unusable.
With over a decade of car repair experience, I've found that the BMW 320 sedan's official recommended maximum wading depth is approximately 25 to 30 centimeters. Why this specific limit? Because its engine air intake is positioned beneath the front bumper with limited ground clearance. Water exceeding the bumper height can easily enter and be sucked into the engine, causing stalling or even engine damage. Always use low gear when wading and maintain slow speed to avoid creating waves that raise water levels. Additionally, checking the air filter and wheel clearances before rainy drives can prevent accidents. For frequent water crossings, consider installing an engine splash shield—but never rely on it for deep water adventures. Regular maintenance should prioritize inspecting underbody seals. Safety first.
