What is the maximum wading depth of the Defender?

According to official information, the Defender's maximum wading depth is 90 cm. Common tire specifications include 275/45R22 and 255/60R20, with body lengths of 5018mm and 4583mm. The vehicle is equipped with an 8-speed automatic transmission (AT) and comes in 5-door 5-seat SUV and 3-door 5-seat SUV body structures. Maximum wading depth refers to the deepest water a vehicle can safely pass through. Generally, the maximum wading depth for sedans does not exceed 30 cm, while SUVs can handle deeper water, though it's best not to exceed 50 cm. Among common models, the GAC Trumpchi GS8 has a maximum wading depth of 30 cm, the Audi A4 32 cm, the Volkswagen Sagitar 30 cm, the Land Rover Range Rover 90 cm, the Jeep Compass 48 cm, and the Highlander 45 cm. SUVs clearly surpass sedans in maximum wading depth. Generally, when driving through water, vehicle owners should take different measures based on the water depth and the vehicle's characteristics, as follows: If the water reaches the exhaust pipe height, it is relatively safe. Even if water enters the exhaust pipe, the pressure inside is sufficient to expel it. As long as the engine is not turned off in the water, water will not flow back into the vehicle. If the water reaches the door frame height, it becomes more dangerous. Most of the vehicle's circuits, electronic components, and sensors are located at the bottom, which could lead to circuit failures, damaging critical electrical components and preventing the car from starting. If the water reaches the air intake height, 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.
I remember the Land Rover Defender has a maximum wading depth of about 90 cm, which is roughly knee-height for an average adult. This specification is a highlight of the vehicle's design, as the Defender's air intake is positioned high up on the fender above the engine bay, effectively preventing water ingestion. At the off-road club, I witnessed real-world tests where the vehicle passed steadily through water up to 80 cm deep, but exceeding this depth significantly increases risks. When wading, it's crucial to drive slowly and maintain a steady speed to avoid water surges. I also believe tire tread patterns and suspension height impact performance – having a wading mode assist is ideal for deeper sections. During routine maintenance, checking door seals and electrical systems is vital, as aging components or water leaks may cause short circuits. While 90 cm is a solid benchmark, during rainy seasons or stream crossings, I recommend pre-measuring water depth with a stick to ensure safe driving.
