The Land Rover Discovery is a mid-size SUV, with off-road capabilities, from the British car maker Land Rover; now a division of Tata Motors. There have been four generations of the vehicle, which was first introduced in 1989. The current Discovery 4 is marketed in North America as the LR4.
Land Rover Discovery has four type, Land Rover Discovery I, Land Rover Discovery II, Land Rover Discovery III and Land Rover Discovery IV. Each type have different specification.
The Discovery was introduced into the United Kingdom in 1989. The company code-named the vehicle "Project Jay". The new model was based on the chassis and drivetrain of the more upmarket Range Rover, but with a lower price aimed at a larger market segment and intended to compete with Japanese offerings. This was the only Discovery generation with four-cylinder engines.The Series II Discovery debuted in autumn 1998 and in the US in 1999. Land Rover promoted that the Discovery Series II had been modified with 720 'differences'. The interior and exterior was re-worked to be less utilitarian, but it was still similar to the Series I. Every body panel was new except the rear door outer skin. The rear body was extended to improve load space but at the expense of added rear overhang, which adversely impacted off-road ability. Changes to the diesel engined models saw the 2495 cc Td5 (in-line direct-injected 5 cylinder) engine introduced, in line with the updated Defender models. This electronically managed engine was smoother, producing more usable torque at lower revs than its 300 Tdi predecessor. 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. The LR3 name was chosen for North American markets due to negative quality associations with the Discovery name and (according to Land Rover) a preference in the American market for alpha-numeric model designations – the second generation Freelander was also re-designated for the North American market as the LR2.The Discovery 4 (called the LR4 in North America) is a heavily updated version of the Discovery 3. Using the same Integrated Body Frame structure, the new Discovery has altered front and rear light units and a restyled front grille and bumper to adopt the same smoother, rounder style as also adapted for the 2010 Range Rover and Range Rover Sport. The Discovery 4 also retains the body-coloured wheel arches and bumpers as the late D3s (early D3s had black plastic trim). The D4 is the first Discovery model to incorporate Daytime Running Lights, these being a row of white LEDs added to the main front lamp unit.
