Platform Heritage

The Land Rover Discovery is a series of five or seven-seater family SUVs, produced under the Land Rover marque, from the British manufacturer Land Rover, and later Jaguar Land Rover. The series is in its fifth generation since 2017. The first one was introduced in 1989, making the Discovery the first new model series since the launch of the 1970 Range Rover – on which it was based – and only the third new product line since the conception of the Land Rover (vehicle and brand) by Rover in 1948. The model is sometimes called influential, as one of the first to market a true off-road capable family car. Although the Range Rover had originally been designed as an everyday four wheel drive car that could be used as both a utility vehicle and a family car, it had progressively moved upmarket through its life to evolve into a luxury vehicle sold at a much higher price point. The Discovery was intended to fulfill the role the Range Rover originally was intended for; a segment which was now dominated by Japanese rivals such as the Nissan Patrol, Mitsubishi Pajero and Toyota Land Cruiser. Although positioned below the Range Rover in the company's line-up, the vehicle was both longer and higher, offered more room in the back, and optionally also more seats. Space utilization became more sophisticated in later generations, but the series keeps offering seats for seven occupants. Despite originally being sold as an affordable alternative to the Range Rover, the Discovery has also progressively moved upmarket through its successive generations to become a bonafide luxury SUV. The second Discovery (1998) was called the Series II, and although it featured an extended rear overhang, it was otherwise an extensive facelift, which carried over the 100 in (2,540 mm) wheelbase frame and rigid, live front and rear axles derived from the original Range Rover. The third generation – succeeding the Series II in 2004 - was either called the Discovery 3 or simply LR3 (in North America and the Middle East). This was a new ground up design, the first all-original design for the Discovery. Although it followed the 2002 third generation Range Rover, also switching to fully independent suspension, it still received a separate, but integrated body and chassis structure. The fourth generation, as of 2009 – like the series II, was again mainly an update of the new generation – marketed as the Discovery 4, or Land Rover LR4 for North American and Middle Eastern markets. The fifth generation of the Discovery, introduced in 2017, no longer sports a numeric suffix. Unlike the previous two generations, it now benefits from a unitary body structure, making it lighter than its predecessor.
