Engine Options 1980:
Primarily the Douvrin 'EM' series inline-four gasoline engines. Commonly available in 1980 were: 1.8L (1777 cc) and 2.0L (1981 cc).
Engine Code Example:
XM7 (1.8L), XL9 (2.0L)
Horsepower Range:
Approx. 99 hp (1.8L) to 106 hp (2.0L), depending on specific tune and market.
Torque Range:
Approx. 140 Nm (1.8L) to 158 Nm (2.0L).
Fuel Delivery:
Typically carburetor-based (e.g., Solex twin-choke), with some later models or specific markets potentially featuring Bosch L-Jetronic fuel injection.
Length Sedan Approx:
4.69 meters (184.6 inches)
Width Approx:
1.76 meters (69.3 inches)
Height Sedan Approx:
1.37 meters (53.9 inches)
Curb Weight Approx:
1,200 - 1,300 kg (2,645 - 2,866 lbs)
Crash Test Data:
Official crash test data for the 1980 model year from independent agencies may be limited or non-existent by modern standards. The CX's unibody construction and advanced (for its time) suspension contributed to its handling and perceived safety.
Braking System:
Hydraulic disc brakes front and rear, often with a tandem master cylinder and a rear load-sensing proportioning valve. The hydropneumatic system also contributed to braking stability.
Steering System:
Hydraulic Power Steering (Diravi system), providing variable assistance and self-centering. This enhances control and reduces driver fatigue.
Seatbelts:
Standard three-point front seatbelts, lap belts in the rear (depending on market and specification).
Audio System:
Factory-fitted radios, often mono, with manual tuning and limited speaker configurations. Cassette players were becoming more common.
Advanced Features For Era:
The Diravi power steering and sophisticated hydropneumatic suspension were highly advanced features for their time, offering unparalleled ride comfort and handling stability.
Connectivity Features:
Minimal by modern standards. Primarily focused on basic vehicle operation and comfort features.
Oil Change Interval:
Typically every 5,000 - 7,500 km (3,000 - 5,000 miles) or 6-12 months, depending on usage and oil type.
Major Service Interval:
Often around 20,000 - 30,000 km (12,000 - 18,000 miles) for inspection of various components, including suspension and braking systems.
Engine Oil:
Refer to manual for specific viscosity (e.g., 10W-40, 15W-50). Citroën specified oils meeting certain standards (e.g., ES-SO XJ+).
Hydropneumatic Fluid:
LHM (Liquide Hydraulique Minéral) or equivalent mineral-based hydraulic fluid. Crucially, do NOT use DOT 3/4/5 brake fluid.
Transmission Fluid Manual:
GL-4 Hypoid Gear Oil (e.g., SAE 75W-90, 80W-90). Specific capacity varies by gearbox type.
Transmission Fluid Automatic:
ATF (Automatic Transmission Fluid) Type A Suffix A or Dexron II (or equivalent). Specific capacity varies.
Coolant:
Ethylene glycol-based antifreeze mixed with distilled water (50/50 ratio). Specific type depends on OEM recommendation at the time.
Suspension Leaks:
Hydropneumatic spheres and seals can degrade over time, leading to height control issues or leaks. Regular system checks are vital.
Electrical Gremlins:
As with many European cars of this era, aging wiring harnesses, connectors, and grounding points can lead to intermittent electrical problems.
Rust And Corrosion:
Vulnerable areas include wheel arches, sills, and the underbody. Proper rust prevention and treatment are essential for longevity.
Carburetor Issues:
Carburetors can become gummed up or require adjustment due to age, affecting fuel mixture and engine performance.
Citroen Legacy:
Citroën is renowned for its innovative and often avant-garde automotive engineering, particularly in suspension and aerodynamics. The CX continued this tradition.
Cx Development:
The CX was developed as a successor to the iconic DS, retaining and evolving its hydropneumatic suspension system. It was launched in 1974 and underwent continuous refinement.
Production Period:
1974-1992
Manufacturing Locations:
Primarily France (Rennes-sur-Vilaine) and selected models in other Citroën plants.
