1973 Land Rover Range Rover 3.5.jpg

The Range Rover Classic is a 4x4, mid-size Sport utility vehicle series produced initially by the Rover (later Land Rover) division of British Leyland, and latterly the Rover Group from 1970 to 1996. The first generation of vehicles produced under the Range Rover name, it debuted as a 2-door; a 4-door became available in 1981, with the 2-door phased out in January 1994. For most of its history it was known simply as the "Range Rover"; Land Rover coined the term "Range Rover Classic" to distinguish it from the P38A which succeeded it when the two were briefly built alongside, and applied the name retrospectively to all first-generation Range Rovers.

Rover's Land Rover Series I launched in 1948 had been designed to be cheap, simple to manufacture, and suitable for hard work in rural terrain, with minimal concessions toward comfort. Rover shortly realised that a market existed for an off-road capable vehicle with more amenities. In 1949 the Land Rover estate car was released, with a coach-built wood-framed body by Tickford. However, the high price of adding such car-like features as seven seats, floor carpets, a heater, a one-piece windscreen resulted in fewer than 700 being sold before being dropped in 1951.

In 1954 Land Rover launched a second iteration estate car, this time aimed at the commercial user who needed an off-road vehicle for carrying passengers without car-like comforts. Based on the commercial panel van variant Land Rover, it had seats fitted to the load space and windows cut into the sides. While available with features such as an interior light, heater, door and floor trims and upgraded seats, the estate car retained the base vehicle's tough and capable suspension – as well as its mediocre road performance.


By the late 1950s Rover had become convinced a market for a more comfortable 4x4 existed in areas such as Africa and Australia, where ordinary motorists faced long journeys on unmade roads that called for four-wheel drive and tough suspension. In 1958 the first of the "Road Rover" development cars was built, combining the Land Rover's tenacity with the comfort of a Rover saloon car. Dubbed the "Road Rover", it featured a Land Rover chassis and running gear clothed in a functional estate car-like body. It never made it into production.

By the 1960s, Rover was becoming aware of the embryonic development of the sport utility vehicle in North America. Proto SUVs such as the International Harvester Scout (1961) and the Ford Bronco (1966) began the skew of 4x4s towards speed and comfort while retaining more than adequate off-road ability for most private users. The Jeep Wagoneer proved the concept further in the direction Rover had several times attempted, but with more power. To provide Rover a nudge to step up, the president of the company's USA operations shipped a Land Rover Series II 88 to Britain fitted with an advanced small block all-aluminium Buick V8 engine.

Rover acknowledged the emerging recreational off-road market in 1967 under Charles Spencer King, and began the "100-inch Station Wagon" programme to develop a radical competitor. Rover bought a Bronco, which featured the sort of long-travel coil spring suspension necessary for the required blend of luxury car comfort and Land Rover's proven off-road ability. King is said to have been convinced of coil springs while driving a Rover P6 across rough scrubland on part of the Solihull factory site that was being redeveloped. He was also convinced that a permanent four-wheel drive transmission was needed both to provide adequate handling and reliably absorb the power required for the vehicle to be competitive. The cost of developing a totally new transmission was spread between the 100-inch SW project and one working on what would become the Land Rover 101 Forward Control. Powerful, light and sturdy, the Buick alloy V8 earned off-road modifications such as carburettors that maintained fuel supply at extreme angles and provision for cranking the engine with a starting handle in emergencies.

The final design featured bodywork largely done by the engineering team rather than David Bache's styling division. Launched in 1970 as "A Car For All Reasons", the new "Range Rover" offered a top speed in excess of 100 mph (160 km/h), a towing capacity of 3.5 tons, spacious accommodation for five, hydraulic disc brakes on all wheels, and a groundbreaking four-speed, dual-range, permanent four-wheel-drive gearbox.

Like other Land Rover vehicles, most of the Range Rover's bodywork skin is constructed from lightweight aluminium, except for the two-section rear tailgate, and the bonnet on all but the earliest models. Apart from minor cosmetic changes, the body design changed very little in its first decade. However, while utility Land Rovers had body panels rolled from a single sheet of aluminium, the Range Rover used aluminium panels hung on a steel 'safety frame' (a method pioneered with great success on the Rover P6 saloon). This allowed the bodywork of the Range Rover to carry much greater structural strength with the steel frame while retaining the corrosion-resistant and easily repaired aluminium outer panels. While the steel frame was designed by the engineering team, it was expected that Rover's stylist David Bache would provide a design for the outer panels for use on the production vehicles. For the prototypes the engineers designed their own functional body panels simply to protect the occupants and to allow the vehicles to be driven legally on the road. However the clean, square-cut and functional design of the prototype was deemed so good that Bache only altered the detailing, such as providing a different front grille and headlamp design. The Range Rover also marked the first appearance of Bache's trademark "symmetric" dashboard, where a common moulding was used for the fascia superstructure on both RHD and LHD versions, onto which the pod-style instrument binnacle was simply mounted on the appropriate side – Bache would use this concept again on both the Rover SD1 and the Austin Metro in later years. The original fascia would later be nicknamed the "Airfix Dashboard" by Range Rover enthusiasts owing to its hard, low quality plastics which, as the vehicle moved upmarket over the years, betrayed its humble beginnings as a utility vehicle, It remained with the Range Rover up until the very last years of production when it was replaced by the "soft dash" (see below)

Early vehicles may be distinguished by the rear 'C' pillars being absent of a vinyl covering which was introduced a little later in the 1970s.

One of the first significant changes came in 1981, with the introduction of a four-door body. Until then, Range Rovers only had two doors, making access to the rear seats rather awkward. These doors were also very large and heavy. Several companies offered conversions to four doors in the late 1970s. That by one of these companies, Monteverdi, was approved for warranty purposes by Land Rover and was closely followed when the company then produced its own development. The four-door version was received well by the public; its popularity was such that the two-door was discontinued in the United Kingdom in 1984, although the two-door continued to be produced to January 1994, mainly for the French market.

The first major push upmarket was in 1984, which saw the availability of leather trim and automatic transmission; this was followed by the 1985 model year, which saw the instrument pod replaced by a more modern one (adapted from the Austin Maestro) and new door cards (using Austin Metro door handles) with walnut inlays.

The front end of the Range Rover was revamped in 1986. This brought a more pedestrian-friendly plastic grille with horizontal slats, and optional front valance with two fog lights. The seat base was lowered and door handles were redesigned, making it more difficult for rear passengers but greatly improving the comfort for taller people in the front. The dashboard switchgear was updated again, now featuring steering column stalks from the Austin Montego, and other miscellaneous items from the Austin Rover car range. Other changes included the windows, tailgate and bonnet, but none of those affected the general design. Bonnet and door hinges gradually evolved out of sight and the fuel filler cap was hidden behind a hinged flap. The last major change to the interior took place in 1994, when the Range Rover was re-designated "Classic" upon the arrival of the replacement P38A version. The car gained a 'soft feel' safety dashboard (derived from that used in the facelifted Series 1 Discovery) with new switches (this time lifted from the Rover 800) and instruments. These end of the line models are popularly called "soft dash" models by the motor trade and by enthusiasts to distinguish them from other members of the Range Rover Classic series.

The Range Rover broke from the Land Rovers of its time by using coil springs instead of the then-common leaf springs. Because of its hefty weight, it also had disc brakes on all four wheels. Originally, it had no power steering, though this was added a few years after its introduction.

One problem with the Range Rover chassis was that it suffered considerably from body roll. Because of this, the suspension was lowered by 20 mm (0.8 in) in 1980, and later gained anti-roll bars.Air suspension was introduced in late 1992 for high-end 1993 models.

Most Range Rovers had a 100-inch (2,540 mm) wheelbase. However, 1992 saw the introduction of a more luxurious model, branded the LSE in the United Kingdom and County LWB (long wheelbase) in the United States, providing expansive rear-passenger legroom absent from the 100-inch wheelbase models. These had a 108-inch (2,743 mm) wheelbase, air suspension and 4.2-litre engines.

The 100-inch Range Rover chassis became the basis for the Land Rover Discovery, introduced in 1989.

Originally, the Range Rover was fitted with a detuned 135 hp (101 kW) version of the Buick-derived Rover V8 engine. The 3,528 cc (3.5 L; 215.3 cu in) engine was increased to a displacement of 3,947 cc (3.9 L; 240.9 cu in) for the 1989 model year, and 4,197 cc (4.2 L; 256.1 cu in) in 1992.

Petrol-fuelled Range Rovers were fitted with carburettors until 1986, when they were replaced by Lucas electronic fuel injection, improving both performance and fuel economy. The Lucas injection system continued to evolve over the next several years, culminating in the 1990 to 1995 Lucas 14CUX. Some export markets retained carburettors, with the original Zenith/Stromberg manufactured units being replaced by Skinners Union (SU)-manufactured items.

From 1979 onwards, Land Rover collaborated with Perkins on Project Iceberg, an effort to develop a diesel version of the Range Rover's 3.5-litre V8 engine. Both naturally aspirated and turbocharged versions were built, but the all-alloy engine blocks failed under the much greater pressures involved in diesel operation. The project was, therefore, abandoned. The effort to strengthen the Rover V8 for diesel operation was not, however, completely wasted; the 4.2-litre petrol variant of the engine used crankshaft castings developed in the Iceberg project.
