The Defender's off-road capability is its signature selling point. The entire range comes standard with Terrain Response 2 system, which automatically adjusts outputs for mud, sand, rocks and other surfaces. The 2026 model also debuts an off-road Active Cruise Control system, which automatically adjusts speed on rough terrain while the driver focuses on steering. Wading depth is 900 mm across the Defender range, and select models also feature ClearSight under-vehicle perspective to see obstacles beneath the car while off-roading.
Defender 嘅越野能力係佢嘅招牌賣點。全線配備 Terrain Response 2 全地形反應系統，可按泥地、沙地、岩石等路面自動調節輸出。2026 年新版仲首次加入主動式越野巡航控制系統，喺崎嶇地形會自動調節車速，駕駛者只需專注轉向。涉水深度方面，Defender 全線可達 900 mm，部分車型仲有 ClearSight 車底透視功能，越野時可以睇清楚車底情況。
