The Land Rover Discovery is a mid-size luxury SUV, from the British manufacturer Land Rover. There have been five generations of the vehicle, the third of which was introduced in 2004, titled Discovery 3 (LR3 in North America).
On 2 April 2004, Land Rover introduced the Discovery 3, marketed as the LR3 in North America. It retained the key features of the Discovery, such as the stepped roofline and steeply raked windscreen.
Land Rover developed a body construction method for the Discovery 3, marketed as Integrated Body Frame (IBF). The engine bay and passenger compartment are built as a monocoque, then mated to a basic ladder-frame chassis for the gearbox and suspension. Land Rover claims IBF combines the virtues of monocoque and ladder-frame – though it makes for a heavier vehicle than a monocoque construction, compromising performance and agility somewhat but adding strength, toughness and adaptability.
