What is the maximum wading depth of the Discovery 4?

According to official specifications, the maximum wading depth of the Discovery 4 is 670mm. Common tire specifications include 285/40R22, 255/55R20, and 275/45R21. The vehicle height is 1888mm, and it is a 5-door, 7-seat SUV. Maximum wading depth refers to the deepest water level a vehicle can safely pass through. Generally, sedans have a maximum wading depth of no more than 300mm, while SUVs can handle deeper water, though it's best not to exceed 500mm. Among common models, the GAC Trumpchi GS8 has a maximum wading depth of 700mm, the Audi A4 has 320mm, the Volkswagen Sagitar has 700mm, the Land Rover Range Rover has 900mm, the Jeep Compass has 800mm, and the Toyota Highlander has 455mm. SUVs generally have higher wading depths than sedans. Generally, when driving through water, vehicle owners should take different measures depending on the water depth and the vehicle's characteristics, as follows: When the water depth reaches the exhaust pipe height, it is still safe. Even if water enters the exhaust pipe, the pressure inside can expel it. As long as the engine is not turned off in the water, water will not flow back into the vehicle. When the water depth reaches the door frame height, it becomes more dangerous. The vehicle's circuits, electronic components, and sensors are mostly located at the bottom, which could lead to short circuits and damage critical electrical components, preventing the car from starting normally. When the water depth reaches the air intake height, it is extremely dangerous. Driving directly into such water could cause the engine to stall immediately, leading to permanent damage or rendering the engine unusable.
When off-roading in the Discovery 4, I love its wading capability the most. The official specification states a maximum depth of 700mm, which is about calf-deep in water. I once drove it along a rain-swollen creek with around 60cm of water depth, and it passed through steadily without the engine stalling. This is thanks to the vehicle's sealed design and the position of the air intake, preventing water from flooding in. When wading, maintain a slow and steady speed—don't rush to avoid waves submerging the hood, and steer clear of deeper areas to prevent electrical damage. After wading, I always check the air filter and wheel arches, removing any mud to maintain the vehicle and prolong its lifespan. Honestly, 700mm is more than enough for most off-road scenarios.
