The Land Rover Discovery (now known in North America as the LR4) is a comfortable 4x4 vehicle (SUV in American-English) from the Land Rover marque. There have been three generations of the vehicle, which is somewhat less expensive than the company's top Range Rover model. The Discovery was introduced in the late 1980s and is the most popular model of Land Rover. It is not as utilitarian as the Defender, but it is very competent off road.

- Beginning MY2012, the world-spec Discovery 4 range will be joined by the Discovery 4 Armoured. Developed in partnership with specialists Centigon, the bulletproofed model is aimed specifically for high-risk customers in Europe or the developing world. The armour fitting includes ballistic steel plates for high-velocity ballistics as well as blast protection against 15 kg of TNT, or its equivalent, and under floor protection against two DM51 hand grenades, all done in accordance with European standards. To cope with the extra weight (3550 kg / 7826 lb), Land Rover has upgrade the engine with a 5.0 liter LR-V8 petrol mill, developing 375 PS (276 kW) and 510 Nm (376 lb-ft). Acceleration from 0 to 100 km/h (62 mph) is 10.6 seconds. They have also upgraded the chassis with air suspension, new air springs and revised damper settings, biggers roll bars and Alcon heavy-duty brakes, heavy wheels and run-flat tires. The Discovery 4 Armoured will come with a 3-year, 80,000 km factory warranty on both the vehicle and the armour.
- For 2011, Land Rover is launching a limited edition Discovery 4 for the UK market called the Landmark Limited Edition. Available only in Santorini Black or Fuji White, it features a set of unique 5-spoke 20-inch alloy wheels with glossy black diamond-turned coating and more upscale Taurus leather interior, which can be specified in Ebony or Ivory (the latter with contrasting stitching). Under the hood, all Landmark models get LR's 3.0 litre twin turbo V6 diesel which is 9% more fuel efficient than the outgoing 2.7 litre mill and emits 10% less CO2.
- For 2010, the LR3/Discovery 3 receives both a facelift and a new name, the LR4/Discovery 4. The new posh SUV sports a new direct-injected 5.0-liter V8 sourced from Jaguar producing 375 hp and 375 lb-ft of torque. The new found grunt is managed through a 6-speed Auto. Besides the aesthetics and the grunt, the Discovery's electronic goodies also get upgrades, most notably, Land Rover's Terrain Response System.
- For 2009, the LR3 (Discovery 3) receives a very subtle facelift. They include fully body colored front bumpers, revised rear bumper and wheel arches (now body colored on top level trims), body colored tailgate lift handle, revised "tungsten" colored side vent, "tungsten" door handles on top level trims, and clear-lens side repeaters on all variants. The range will also be sporting three new metallic paint schemes: Santorini Black, Galway Green and Bournville as well as "Almond" trim color for the interior. Also on offer is the inclusion of a new set of 19-inch 7-spoke alloy wheels. Pricing starts at £29,950 and UK customers will be able to get theirs as early as August 2008. 
- As the LR3 only debuted in 2005, there are no cosmetic changes for 2006. The biggest update, however, is the addition of a V6 version, making the LR3 lineup more versatile and relatively more affordable.

Current generation (2010-Present)Edit
Third generation (2005-2009)Edit
On 2 April 2004, owners Ford Motor Company introduced a new Discovery 3 (or LR3 in the US) for the 2005 model year.
The Series II Discovery was long over-due for replacement. Although still a capable and popular vehicle, its chassis, coil-spring suspension and beam-axle layout had changed very little since the launch of the original Discovery in 1989. In turn, that vehicle used essentially the same underpinnings as the original Range Rover, launched in 1970. The Discovery II was beginning to lose sales to more sophisticated 'working' 4x4 vehicles from Japan (such as the Toyota Land Cruiser and Mitsubishi Shogun) and 'sports' 4x4s from Europe (such as the BMW X5 and Mercedes-Benz ML-Class). A replacement vehicle had been planned for many years, but the project had been delayed many times due to the break up of the Rover Group in 2000 and the need to replace the Range Rover in 2001.
The Discovery 3 (LR3 in North America) was an entirely new design, sharing not a single component with the outgoing model. Its styling is still traditional Land Rover, with function dictating the look, rather than fashion, and with lots of horizontal and vertical lines. It retains the key features of the Discovery, such as the stepped roofline and steeply-raked windscreen.
Construction-wise, Land Rover developed an all-new method which they called 'Integrated Body Frame'. The previous Discovery models had used a traditional, strong ladder-frame chassis. Whilst tough in off-road use, these are heavy and detract from the on-road handling of the vehicle. Monocoque vehicles are more rigid, giving improved high-speed handling, but can be damaged by the stresses involved in heavy off-road use. In the IBF the body, engine bay and passenger compartment is built as a monocoque, which is mated to a basic ladder-chassis holding the gearbox and suspension. It claimed to combine the virtues of both systems, but does make the Discovery 3 uncommonly heavy for its size stunting on-road performance and off-road agility.
Another big change was the fitting of fully independent suspension. Like the Series III Range Rover, this was an air suspension system, which allowed the ride-height of the vehicle to be altered by simply pumping up or deflating the air bags. The vehicle can be raised to provide ground clearance when off-road, but lowered at high speeds to improve handling. FIS has been seen as inferior to the older beam-axle when off-road due to its tendency to make the vehicle ground out. Land Rover developed 'cross-linked' air suspension to solve this problem- when needed, the suspension mimics the action of a beam axle (as one wheel drops, the other rises). In the UK and European markets, a coil-spring independent suspension system was offered on the base model. This model was unique in the range by having only 5 seats and only being available with the 2.7-litre diesel engine. This model lacked the Terrain Response system (see below).
All this was designed to make the new vehicle suitable for a changing 4x4 market. Ultimate off-road ability was becoming less important compared to refined on-road manners. Land Rover was determined that the Discovery 3 would retain the brand's reputation as a top-performing off-road vehicle, whilst also being a good road car. Whilst the Discovery 3 was not as good in the handling stakes as some of the competition, it was much improved over the previous models and its off-road credentials remained intact.
The engines used in the Discovery 3 were all taken from Land Rover's sister company, Jaguar. A 2.7-litre, 195-horsepower (145 kW) V6 diesel engine (the TdV6) was intended to be the biggest seller in Europe. For the US-market and as the high-performance option elsewhere, a 4.4 litre petrol V8 of 280-horsepower (209 kW) was chosen. A 4.0-litre V6 petrol engine taken from the Ford stable was available in the USA and Australia. Before launch, there were rumours that Land Rover may introduce the diesel unit to the American market, but the use of high-sulphur diesel fuel, for which the TdV6 is not designed in that market made this fitment unlikely.
The gearboxes on the Discovery 3 were also all-new. For the diesel engine, a 6-speed manual gearbox was standard. As an option, and as standard on the V8 engine, a 6-speed automatic transmission was available. Both came with a 2-speed transfer box and permanent 4-wheel-drive. A computer controlled progressively locking central differential ensured traction was retained in tough conditions. A similar differential was available on the rear axle to aid traction.
The Discovery 3 was fitted with Land Rover's full armoury of electronic traction control systems. Hill Descent Control (HDC) prevented vehicle 'runaways' when descending steep gradients and 4-wheel Electronic Traction Control (4ETC) prevented wheel spin in low-traction conditions. An on-road system, Dynamic Stability Control (DSC) prevented skidding when steering and braking at speed.
Arguably the biggest feature of the new vehicle was the innovative 'Terrain Response' system (this system won a US Scientist award in 2005). Previously, off-road driving had been a skill that many drivers found daunting. A wide-ranging knowledge of the vehicle was needed to be able to select the correct gear, transfer ratio, various differential systems and master various techniques required for tackling steep hills, deep water and other tough terrain. Terrain Response attempted to take away as many of the difficulties as possible. The driver selected a terrain type on a dial in the cab of the vehicle (the options are 'Sand', 'Ice/Grass/Snow', 'Mud/Ruts' and 'Rock Crawl'.) The on-board computer systems then select the correct gearbox settings, adjust the suspension height, adjust the differential lock settings and even alter the throttle response of the engine suitable for the terrain. For example, in 'Rock Crawl', the suspension is raised to its maximum height, the differentials are locked, Low Ratio is engaged and the throttle response is altered to provide low-speed control. The driver retained some manual control over the off-road systems, being able to select the Transfer Box ratio and the suspension height manually, although use of the Terrain Response system is needed to allow full use of the vehicles capabilities.
As well as new mechanical and electronic systems, the Discovery 3 introduced much more advanced and modern design to the interior and exterior of the vehicle. The original 1989 Discovery's looks had been determined by limited funds and the consequent use of first-generation Range Rover components. These continued to influence the Series II. The Discovery 3 was able to have a fresh, minimalist style. The interior was much improved, with a highly flexible 7-seat layout. Unlike the older models, adults could comfortably use all 7 seats. Passengers in the rearmost row now entered through the rear side doors, instead of the tailgate as in previous versions. The driver benefited from a modern satellite on- and off-road GPS. When in off-road modes, the screen showed a schematic of the vehicle, displaying the amount of suspension movement, angle the front wheels were steering, the status of the locking differentials and icons showing which mode the Terrain Response was in, and what gear was selected on automatic versions.
The vehicle was very well received by the press on its launch, with the Terrain Response system, vastly improved on-road dynamics and clever interior design being selected for wide praise. The new look was disliked by some (descriptions such as 'van-like' were used), and the large, blank rear panel, now devoid of the spare wheel, was a controversial point. Others pointed out that the diesel engine still lagged behind the competition in power (especially given the weight of the vehicle), but overall the vehicle scored highly. A high-point in the new Discovery's launch season came when Jeremy Clarkson of the BBC's Top Gear motoring show drove one to the top of a Scottish mountain, where no vehicle had previously reached.
Second Generation (1998-2004)Edit
The Series II Discovery debuted in 1998. The interior and exterior was re-worked to be less utilitarian, but it was still very similar to the Series I. However, every body panel was new (and incompatible) except the rear door outer skin. The rear body was extended to improve load space but at the expense of added rear overhang, which adveresely impacted off-road ability. However overall off-road ability remains impressive and in practical terms, choice of tyres is far more relevant. Changes to the diesel engined models saw the 2495cc Td5 (in-line direct-injected 5 cylinder) engine introduced, in line with the updated Defender models. This electronically managed engine was smoother, producing more useable torque at lower revs than its 300 Tdi predecessor. ACE (Active Cornering Enhancement, an electronically controlled hydraulic anti-roll bar system) was fitted to some versions, which reduced cornering roll to insignificant proportions. Self-levelling air springs were fitted to some models and European type-approval for 7-seat vehicles was only given for air-sprung cars.
The locking centre differential was still fitted, although the linkage to operate it was not attached, as Land Rover believed that the traction control and newly-developed Hill Descent Control would render it redundant. In 2002, US models saw the mechanism itself finally removed. At this time the mechanism was removed on European 02 Model Year vehicles and remained fully deleted until the face-lifted model was introduced later in that year. Customer demand saw the mechanism and controls fully reinstated as a cost option only (standard on top of range HSE/ES vehicles) on UK/Irish models. The "face-lift" models are easily identified by new "pocketed" headlamps which matched the Range Rover and face-lifted Freelander models. As with earlier models, however, this can be deceptive since kits are available to modify 1998-2002 vehicles with the newer lights.
A small number of Discovery II Commercial models were produced by Land Rover Special Vehicles, this time based on the five-door bodyshell but with the windows rendered opaque to give van-like appearance and security. Normal vehicles were exported to Republic of Ireland, where the rear side windows were smashed and rear seats were destroyed in the presence of a Revenue official, to offer a model that avoided the usurous Vehicle Registration Tax (saving approx.40%).
First Generation/Origins (1989–1997)Edit
Series I The Land Rover Discovery was introduced into the United Kingdom in 1989. The company code-named the vehicle "Project Jay", and came close to calling it the "Prarie Rover" until the decision was made to improve the overall branding strategy, eventually leading to the Land Rover name becoming detached from any specific model (at the launch of the "Defender" name.) 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.
The Discovery was initially available in a three door version, partly to avoid eating into the market of the more expensive Range Rover. The five door became available the following year. Both were fitted with five seats, and an option was made available to have two further seats fitted in the "boot" area at the back of the car. A two-seater, three-door Discovery Commercial version, lacking rear windows, was later offered by Land Rover Special Vehicles. Pre-1994, the Discovery was available with either the 2.5L 200 Turbo Direct Injection (Tdi) engine or the 3.5L Rover V8. Early V8s used a twin SU carburettor system, moving over to Lucas fuel injection in 1990. In the UK, V8 models are comparatively rare, the majority of Discovery owners preferring the more economical diesel engines. Consequently, resale prices of V8-engined vehicles are lower than the more popular diesel counterparts. In the North American market, the situation was reversed and the vast majority of vehicles sold were fitted with the V8. A two litre petrol engine from the Rover stable was briefly available in a model known as the 2.0 Mpi. This was intended to attract fleet managers, since UK (and Italian)Tax laws benefitted vehicles under two litres. A combination of changes in taxation and the engine being woefully underpowered for such a heavy vehicle led to the demise of this engine, despite the kudos of being the engine fitted to several Discoveries supplied to the British Royal family.
In 1994, many changes were made to the Discovery I: the 200TDi and 3.5L V8 engines were replaced with the 2.5L 300TDi and 3.9L Rover V8 engines, the 300TDi introducing a Bosch electronic emmisions control for certain models and markets. At around this time a stronger R380 gearbox was fitted to all manual models. The newer models featured larger headlamps and a second set of rear lights in the bumper. A notorious annoyance with the new rear lights was that the wiring was changed several times to meet real or expected European safety legislation. Some vehicles are left with a frustrating arrangement where the vulnerable bumper contains the only working direction-indicator lights; other examples have these lights duplicated in the traditional rear pillar location.
The designers of the original model had been forced to economise and use the "parts-bin" of the then parent-company, Rover. The 200 series used the windscreen from the Range Rover, door handles from the Morris Marina and tail lights from the Austin Maestro van. The favour was returned when the facelifted Discovery dashboard was also fitted as part of the final facelift to the first-generation Range Rover, though with minor differences reflecting the vehicle's higher status, such as an analogue rather than digital clock.
1994 also marked the first year that the Discovery was sold in the United States. Airbags were incorporated into the design of the 1994 model to meet the requirements of US motor vehicle regulations, though they were not fitted as standard in all markets. All models sold in the US utilised the 3.9L V8 engine.
As with all Land Rover vehicles designed since the Series models which had switchable [Two wheel drive|2]] and 4 wheel drive, the transmission is a permanent four wheel drive system, with a locking centre differential at the transfer box. In common with much of the rest of the Land Rover range, the handbrake acts on the transmission at the back of the transfer box.
In Japan, a badge-engineered version of the Series I was offered, called the Honda Crossroad.
In Australia, the vehicle managed to be awarded '4WD of the Year' by virtually all of the 4WD press, impressing the often conservative journalists of the 'hard-core' magazines when it effortlessly ambled where the traditionally highly-rated Toyota Land Cruiser and Nissan Patrol had to scramble. It was widely hailed as the first time that electonics actually out-performed trusted mechanical systems, although most sounded a note of caution about long-term reliability and serviceability. Despite these reviews, and a price tag very similar to the Land Cruiser, it did not set the market alight.
Design quirks and odditiesEdit
Amongst the off-road driving and Land Rover enthusiast community, the all-new Discovery has gradually gained acceptance. Given the improved road-going qualities of the vehicle, many were worried that the vehicle's off-road abilities would be comprimised, and others expressed doubts about relying on electronic systems in extreme conditions. However, by 2006, 2 years after the vehicle's launch, the vehicle's abilities and reliability have been proved both by the press and private owners. Land Rover and many aftermarket companies have developed off-road equipment such as winch, bull-bars, under-body protection kits, snorkels and roof-racks for the new Discovery, to optimise its off-road use.
In 2006 Land Rover will use the Discovery 3 in its G4 Challenge, alongside the Range Rover Sport. The vehicles used are all in standard mechanical form, and are fitted with equipment from the standard Land Rover brochures.
