Land Rover Discovery, also frequently just called "Disco" in slang or popular language, is a series of medium to large premium SUVs, produced under the Land Rover marque, from the British manufacturer Land Rover, and later Jaguar Land Rover. The series is currently in its fifth iteration (or third generation, according to the manufacturer).

The third-generation Discovery was unveiled in the grounds of Packington Hall near Meriden, UK on 28 September 2016, the eve of the 2016. Paris Motor Show, and went on sale in the UK in February 2017. Built on a platform shared with the Range Rover and Range Rover Sport, the current Discovery leaves behindmany of the design traditions of former generations for a more modern, though less overtly practical, design.

This model also marks the return of the Discovery marque in the U.S. market, replacing the LR moniker of the previous generation models. There are five seat, seven seat and commercial van versions in the UK, Ireland and other European markets. This is the first Discovery that will be manufactured outside the UK, with production being moved to Slovakia in 2019. A Discovery 3.0 TD6 achieved an AIR Index emission rating of "A" (A=Best, E=Worst) when independently tested in 2019.

Design

The design of the third-generation Discovery was previewed by the Discovery Vision Concept at the 2014 New York Auto Show. In profile, the exterior design is also very similar to the small Discovery Sport model. In contrast to previous Discovery models, the third-generation has a much more rounded shape, eschewing the traditional angular design. The tail lights have changed from a vertical orientation to horizontal, and the third-row side glass no longer blends into the roof glass. The tailgate is no longer horizontally split and has been replaced with a conventional top hinged tailgate made from composite, but retaining the asymmetrically mounted license plate as a design cue from previous generations of the Discovery. The roof is still stepped over the third row, though it is now largely cosmetic in comparison to the previous models and the roof now has a strong taper to the back. The interior closely follows that from other contemporary Land Rover models, while continuing the 3-row tradition of the Discovery.

Mechanical

The new Discovery 5 incorporates several changes over its predecessors. For the first time, the Discovery is based around Land Rover's aluminium architecture, first introduced on the Range Rover (L405). The use of aluminium chassis and body panels gives a weight loss of up to 480 kg over its predecessor. This weight loss combined with a new aerodynamic design,
a 17 percent lower Cd, achieves a fuel efficiency improvement over previous Discovery generations. The new Discovery is offered with a combination of V6 petrol and diesel engines. All Discovery 5s are equipped with a standard 8 speed automatic transmission. An available option package adds a two-speed transfer case (low range gearbox) and the option of an actively locking rear differential. Coil springs are now standard on base trim models, while air suspension is still offered as an option. Land Rover also introduces Terrain Response 2 on the Discovery 5. Similarly, to the first generation of Terrain Response, Terrain Response 2 constantly monitors wheel slip, wheel speed, angle of approach or departure, and the suspension's compression or rebound to adjust the anti-lock braking system, throttle response, differentials and traction control systems. The driver can select modes for snow, grass, gravel, mud ruts, sand, or rock crawling by the spin of a dial on the centre console. Terrain Response 2 also introduces a new 'Auto' mode that allows the vehicles computer to select the most appropriate mode on its own.
The Discovery 5 is the first Discovery to be built on a unibody chassis, unlike its predecessors which were built body on frame. This allows the vehicle to have higher torsional rigidity with less weight. According to the automotive press, the latest generation has a higher wading depth (up to 35.6 inches (90 cm)), improved ground clearance and a more comfortable ride while traversing adverse terrain.
