The Citroën CX is an automobile produced by the French automaker Citroën from 1974 to 1991. Citroën sold nearly 1.2 million CXs during its 16 years of production. The CX was voted European Car of the Year in 1975.
It is considered by some enthusiasts as the last "real Citroën" before Peugeot took control of the company in 1974. "Real Citroën" refers to the trademark avant garde technical and design innovation, prized by marque loyalists. [1]
Available models were a four-door fastback, a break (estate), and a long-wheelbase model built on the break chassis. The CX employed Citroën's unique hydropneumatic self-leveling suspension system.

[edit] History
The CX was initially a huge sales success in Europe, producing a little over 132,000 units in 1978. It accrued new customers beyond the loyal Citroën DS customer base and brought the technology of the advanced, but somewhat impractical Citroën SM to the masses. Unlike its principal competitors, the CX did not have world-wide distribution — the cost of development and improvements had to be met from a geographically small sales base.
It is hard to mistake the CX for any other vehicle. Robert Opron penned the dramatic flowing lines and sharp Kamm tail of the CX, which resembles a larger version of the 1970 Citroën GS. The CX also bears a resemblance to a 1967 design study by Pininfarina for the BMC called the 1800 berlina aerodynamica, yet both Citroën and Pininfarina deny any contacts during this period. However, it is also clear that the CX design is a clear evolution from the DS designed by the team headed by Gillet. Hence, the CX followed the legacy left by the very famous DS in proposing the sleekest design on the market for an executive car which were all going for very clumsy square shapes. Its aerodynamic is still one of the best ever produced on a car. This allowed the use of smaller engines to obtain the same speeds as other executive sedans which would need much larger engines.
This car featured one of the most modern designs of its time. The car combined the unique hydro-pneumatic integral self-leveling suspension, speed-adjustable DIRAVI power steering (first introduced on the Citroen SM), and a unique interior design that did away with steering column stalks, allowing the driver to reach all controls with his or her hands on the steering wheel. The British magazine "Car" described the sensation of driving a CX as hovering over road irregularities, much like a ship traversing above the ocean floor.
The Citroën suspension made these large sedans to hold the road as no other cars could, they could even follow smaller sports cars into the sinuous alpine roads. This same suspension was used under licence by the Rolls-Royce Camargue and the Mercedes-Benz 450SEL 6.9 and Mercedes-Benz W124 since it was considered the best ever made.
The CX was a transverse engine design, in contrast to the mid-engine layout of the Traction Avant and DS. This design saved space; the CX was a foot shorter than the DS. The short wheelbase CX fastback had insufficient rear legroom to function as a chauffeur driven limousine (a common use for the spacious DS model), so in 1976, Citroën introduced a 10 inch (25 centimetre) longer version, the "Prestige" variant, which used the wheelbase of the longer Safari/Familiale estate.The Prestige offered more rear leg-room than any other standard-sized sedan in the world. The prestige later,in 1977 gained a raised roofline to add more comfort.
The CX was very slowly developed and improved, with key elements the car needed to compete in its market segment taking many years to emerge. Decent factory rustproofing, much needed improved quality interior trim and an automatic transmission were added in 1981 and a turbocharger in 1984. The parent company PSA Peugeot Citroën was fielding three competitors in the executive car segment, the Peugeot 604, the Talbot Tagora, and the CX, each competing for PSA's scarce financial resources. The seeds of PSA's competitive retreat, from this traditionally important segment, were sown during this period of diffused efforts.
The 1984 turbo-powered 2.5 L diesel motor did make the CX Turbo-D 2.5 the fastest diesel sedan in the world, able to reach speeds up to 195 km/h (121 mph). Diesels account for more than half the market for executive cars in France.
The CX eventually acquired a reputation for high running costs, which over time cut sales. Ironically, it was the components standard to any automobile (steel, door hinges, starter motors, electrical connections, etc.) that proved troublesome in service, while the advanced components were unobtrusive. The quality of construction improved too slowly to eliminate this perception.
The CX was originally developed as a rotary engined car — with several downstream consequences. First, the small Comotor three-rotor rotary engine was not economical and the entire rotary project was scrapped the same year the CX was introduced, Second, Citroën went bankrupt in 1974, because it had too many development projects going at the same time; bankruptcy distracted the company from the CX's launch. Finally, the resulting engine bay was too small for anything but a modest inline four-cylinder engine. The car thus had 15 different four-cylinder engines during its life, each offering a minuscule improvement over the last, while the market segment had moved on to the six-cylinder engine.
Although the minor 1986 Series 2 changes did create initial interest from press and public alike, they did little to revive sales with around 35,000 units being produced in 1986 and the same again in 1987.
While the revolutionary and timeless DS achieved its greatest sales success at the same point in its 20 year lifecycle, the CX design was subject to more intense competitive pressures by other automakers, that succeeded in using the CX design as a template for improvement.
[edit] International sales and production
In 1984, Citroën sold 2,500 CXs to China and nearly succeeded in getting the "large car" contract that would have made the CX the most common vehicle in China. The Chinese government decided to award this contract to Volkswagen, and instead gave Citroën the rights to the "compact car" segment, with what today is known as the Dongfeng Peugeot-Citroën Automobile factory, producing over 100,000 cars per year. Also it was produced in South America since March 1978 starting with the a bit more than 90 hp (67 kW)., CX 2000 Super in Citroën's facility of Arica in Chile. The car achieved good sales numbers and set a technological gap with its current competition (at that moment was one of the most complex car built in the Americas). Later, problems with suspension units, engine troubles and hard Japanese competition played against. Production at the Chilean facility continued until 1984 ending with the fully equipped 128 hp (95 kW), widened front track CX 2400 Pallas, top of the line version. Common parts from the CX were used in other more exclusive cars. The rear view mirrors of the Jaguar XJ220 are exactly the same as the ones used in the 2-Series.
[edit] Replacing the CX
Successful competitors in this market segment (Mercedes-Benz W124, Audi 100, & BMW 5 Series) have adopted a cycle of redesign and substantial improvement every seven years. Despite the success of the CX design (and the unbroken legacy of dominance in this segment stretching back to 1934), there was no new and improved "big Citroën" model on the horizon by 1981. CX sales began to slide and never recovered.
Citroën tried to operate independently and design a CX replacement that updated the flowing CX design (in 1980 and again in 1986). Each time, the parent company PSA Peugeot Citroën killed the project and fired the Citroën designers responsible.
Citroën did incur the expense of designing an entirely new gasoline 4 cylinder engine in 1984 for the top of range cars - this allowed the CX to go slightly faster at the cost of slightly worse fuel economy. The market demanded a six cylinder engine.
The CX was finally replaced by the XM in 1989. This vehicle was based on the same chassis as the Peugeot 605, styled in a distinctive, angular fashion, and fitted with self-levelling hydropneumatic suspension, featuring new electronic controls and branded Hydractive suspension. It also featured a hatchback and a conventional interior rather than the starship command deck of the CX.
The XM at first achieved annual sales similar to the modest totals of the CX in the last decade of its life, before a total collapse in demand set in around 1995. It was retired without replacement in 2000.
The 2006 Citroën C6, first announced as the C6 Lignage concept car in 1999, appears to be the direct descendant of the CX. The design of the Citroën flagship is directly inspired by the personality of the CX.
[edit] Design variations
At launch in 1974, the car was rushed to market, with some teething issues.Some very early models do not have power steering.
The Safari estate, produced from 1975 to 1991 was joined by the seven-seat Familiale, both taking full advantage of the CX's integral self-leveling suspension to support heavy bodies.
Both petrol and diesel-powered models were available in various engine sizes including turbocharged versions. The top-end sports model, alongside the CX Prestige luxury model, was the CX 25 GTi Turbo, launched in autumn 1984, rated at 168 hp (122 kW) and a top-speed of 220 km/h (137 mph).
Manual, semi-automatic ("C-Matic") and fully-automatic transmissions were fitted, with a fully-automatic ZF transmission replacing the C-Matic in 1981. Luxury trim-level models were badged as Pallas and sports variants as GTi. The long-wheelbase models were badged as Prestige (petrol engine) or Limousine (diesel). The factory never produced the CX with both the powerful turbocharged petrol engine and automatic transmission in one car.
The Series 1 vehicles (1974-85) were characterised by stainless steel front and rear bumpers,hydropneumatic suspension as compliant and soft as the DS, and a "spaceship" style dashboard featuring a revolving drum speedometer and tachometer.
In July 1985 the styling was revised, and became known as the Series 2. The cars lost some of their earlier distinctiveness. The suspension became stiffer in certain models. Plastic bumpers were the most notable exterior change, giving what some say is a more aggressive look, as opposed to the more elegant series 1 design. Although the dashboard retained the "pod" housing for the instrumentaion, it lost the revolving drum speedometer and received a sloping centre dash area and the radio migrating to a position sideways and between the front seats, with the height corrector & heating controls moving to the centre console.
The CX was frequently used as an ambulance and camera car, applications where the cosseting suspension was especially valuable. There were a number of CX estates elongated and retrofitted with a second rear axle, mostly used for high speed bulk transport such as carrying newspapers across Europe. They are known as the "loadrunner" variant. Most of them were prepared by the French company Tissier.
The last CX was the venerable Safari Estate, to this day still one of the largest, and because of its suspension, most practical family cars available in Europe.
The most collectible CX models are the very rare Series 1 GTi Turbo, and the Series 2 Prestige Turbo.
1,170,645 CXs were sold from 1974 to 1991.
[edit] CX in North America
The CX was never sold in North American markets by PSA Peugeot Citroën, but many Americans were still able to obtain the car through alternate means.
As an engineering innovator, Citroën was constantly running into issues where U.S. design legislation prohibited certain technology and designs the CX employed: items that define many automobile designs today, like mineral oil brake fluid, aerodynamic headlights, directional headlights, and height adjustable suspension. The regulators have since reconsidered the wisdom of each regulation that bedevilled Citroën; most have been repealed in the light of developing technology.
The final nail in the coffin was the decision by the U.S. agency NHTSA to prohibit passenger vehicles with height adjustable suspension, starting January 1974. Citroën actually built 1974 model year cars for the U.S., but was legally barred from selling them.
Since height adjustable suspension was an integral feature of the CX design, there was no way to engineer around it. Even financially powerful Mercedes-Benz succumbed and had to delete height adjustable suspension from its flagship 6.9 in the U.S.
A few CXs came to North America under unclear circumstances during the 1970s, but the floodgates opened when Ronald Reagan repealed the ban on height adjustable suspension in 1981. As with any other grey market car, the CX could be imported and brought into compliance with the unique design regulations applied by the U.S.
In addition to personal imports, several companies began converting and selling CXs to Americans. These vehicles were not "grey market" cars, but officially imported vehicles remanufactured and type approved for the U.S. These companies suffered legal harassment from PSA Peugeot Citroën. Despite all this and with no advertising, and a minimal service network, the powerful cult brand of Citroën still managed to sell about 1,000 cars at approximately double the price of the same vehicle imported conventionally.
Today the U.S. Government exempts cars older than 25 years from all design legislation, so most CXs can be freely imported. The Canadian government applies a similar rule after 15 years.
[edit] Notable uses
The CX Prestige model was used by the French government, including former president Jacques Chirac. The CX was also the official car of Erich Honecker, who ordered several extended versions of the CX for official DDR use. The Norwegian government used it in the 80's, and the King of Norway Harald V had one in the 70's, as did Panamanian dictator Manuel Noriega.
