s you would expect of a vehicle that has taken explorers to the ends of the earth and back, Discovery was developed for the most extreme conditions. The entire instrument panel, for example, is bench-tested before installation. Chassis components are obviously robust, but even the lug nuts are massive compared to those of ordinary vehicles. It is this kind of attention to detail that gives Discovery its reputation for durability, and prepares it for the extraordinary life each Discovery is expected to lead.

Both the wax-sealed frame and the welded-steel inner body receive extensive anti-corrosion treatments before assembly, including Land Rover's special electrophoretic process. This procedure uses electricity to create a chemical bond between the metal and finish, ensuring that the chassis receives an even and hard-wearing coating.
Beyond the stout 14-gauge steel frame and the corrosion-resistant aluminum body panels, Discovery's mechanical components are also designed for durability and longevity.
Both front and rear axles, for example, have fully floating hubs, which put less load on the axle shafts. All of the front axle's moving parts are completely enclosed inside the axle housing for protection from dirt, debris and moisture. Suspension components, some of which are made of forged steel, are designed for the rigors of off-road duty, not to mention the occasional pothole. Most chassis components are positioned inside the rails of the ladder frame for added protection.
While the V-8 engine features a light weight aluminum alloy block, the cylinders are lined with steel for added durability. Even Discovery's interior leather, fabric and synthetic materials are designed for the use and even abuse of an active lifestyle... or the sometimes carefree habits of young children.
