Approximately 1,300 - 1,450 kg (2,866 - 3,197 lbs) depending on engine and equipment.
Crash Test Availability:
No official standardized crash test ratings available from modern agencies for this era of vehicle. However, design emphasized structural integrity and occupant protection for its time.
Braking System:
Front: Ventilated discs; Rear: Solid discs. Powered by the hydropneumatic system with a central hydraulic circuit and a separate circuit for the rear brakes and handbrake.
Seatbelts:
Three-point inertia-reel seatbelts in the front, lap belts in the rear.
Steering Column:
Collapsible steering column.
Audio System:
Standard factory radio cassette player, often with manual antenna operation. Limited digital integration typical of the late 1980s.
Cruise Control:
Optional on some higher-trim models.
Connectivity Features:
N/A. No built-in Bluetooth, USB, or smartphone integration.
Oil Change:
Typically every 5,000 - 7,500 km (3,000 - 4,500 miles) or 6-12 months, depending on driving conditions.
Lhm Flush:
Citroën recommends LHM fluid flushing and replacement every 30,000 - 60,000 km (18,000 - 36,000 miles) for optimal system performance and longevity.
Engine Oil:
API SF/SG classification, viscosity typically 10W-40 or 20W-50 (check owner's manual for precise recommendations based on climate).
Lhm Fluid:
Citroën LDS fluid or compatible LHS 2 fluid is critical for suspension, steering, and brakes. Using incorrect fluid can cause catastrophic system failure. Capacity approximately 4.5 - 5 liters.
Coolant:
Ethylene glycol-based antifreeze, typically a 50/50 mix with distilled water. Capacity approximately 7-8 liters.
Hydropneumatic System:
Leaking spheres, worn seals, pump wear, and the need for regular LHM fluid changes are common. The system's complexity requires specialized knowledge.
Electrical Gremlins:
Corrosion in connectors, aging wiring insulation, and the original electrical system's complexity can lead to intermittent faults. Thorough diagnostic procedures are essential.
Rust:
Like many cars of this era, rust can be a significant issue, especially around wheel arches, sills, and the subframes. Regular inspection and preventative treatment are crucial.
Citroen Innovation:
Citroën has a long history of pioneering automotive technology, including hydropneumatic suspension, front-wheel drive, and aerodynamic design, all of which are central to the CX.
Cx Development:
The CX was designed as the successor to the iconic DS, featuring a more modern, aerodynamic shape and a front-wheel-drive layout. The Series 2 (introduced in 1985) brought styling updates and technical refinements.
Production Years:
1974-1991
Manufacturing Locations:
Mainly France (Rennes-la-Janais)
European Car Of The Year:
The Citroën CX was not a European Car of the Year winner, but its predecessor, the DS, was highly acclaimed. The CX was recognized for its comfort and innovative design.
