According to official specifications, the Defender has a maximum wading depth of 90 cm. Common tire specifications include 275/45R22 and 255/60R20, with body lengths of 5018mm and 4583mm available. The vehicle is equipped with an 8-speed automatic transmission (AT) and comes in both 5-door 5-seat SUV and 3-door 5-seat SUV configurations. Maximum wading depth refers to the deepest water level a vehicle can safely pass through. Generally, sedans have a maximum wading depth not exceeding 30 cm, while SUVs can handle deeper water but should ideally not exceed 50 cm. Among common models: GAC Trumpchi GS8 has 30 cm, Audi A4 has 32 cm, Volkswagen Sagitar has 30 cm, Land Rover Range Rover has 90 cm, Jeep Compass has 48 cm, and Highlander has 45 cm. SUVs clearly outperform sedans in wading capability. Generally, when driving through water, different precautions should be taken based on depth and vehicle characteristics: When water reaches exhaust pipe level: Relatively safe. Even if water enters the exhaust, internal pressure can expel it. Just avoid stalling in water to prevent backflow. When water reaches door sill level: More dangerous. Most electrical components and sensors are located at the vehicle's base, risking short circuits that may damage critical systems and prevent startup. When water reaches air intake level: Extremely hazardous. Driving through such conditions may cause immediate engine stall, potentially resulting in permanent engine damage or complete failure.
