2005 Land Rover LR3
New frame structure
Land Rover emphasizes that the entirely new frame structure of its LR3 is not derived, copied, or modified from existing architecture. Instead, the foundation marks “the future of Land Rover”, as this platform will find its way into upcoming Rovers. The LR3 uses an integrated body structure that combines high strength steel frame rails and a one-piece body construction. It is neither a unit-body nor body-on-frame configuration, although Land Rover says the benefits of both are provided. Hydroforming, the process of using fluid pressure to form shapes from a tubular blank, was used throughout. Since hydro-forming allows more flexibility in shape, a more complex, yet efficient, frame design can be achieved. Safety is also enhanced, as the side members are more substantial and parts such as the fuel tank are better protected. Finally, and most importantly to off-road users, the new frame provides excellent approach and departure angles by minimizing front and rear overhangs.
