Power Output Typical:
2.0L: ~115 PS; 2.2L: ~120 PS; 2.5D: ~75 PS; 2.5 Turbo D: ~95 PS (figures vary by specific model and market).
Torque Output Typical:
2.0L: ~170 Nm; 2.2L: ~180 Nm; 2.5D: ~130 Nm; 2.5 Turbo D: ~180 Nm (figures vary).
Fuel Delivery:
Mechanical fuel injection (Bosch K-Jetronic on petrol models), indirect diesel injection on diesel variants.
Ignition System:
Electronic ignition (e.g., Bosch ignition modules, distributors).
Timing Belt Interval:
Typically 60,000 km or 4 years (refer to specific engine variant within the manual for exact intervals).
Manual Transmission:
Citroën C353 5-speed manual transmission.
Automatic Transmission:
ZF 4HP18 4-speed automatic transmission (optional on many variants).
Clutch Type:
Hydraulically operated single dry plate clutch.
Manual Transmission Fluid Type:
GL-4 gear oil (e.g., SAE 75W-80 or 75W-90).
Automatic Transmission Fluid Type:
TUFFAUX LT-2 or equivalent ATF (Automatic Transmission Fluid).
Crash Test History:
While formal modern crash test ratings are scarce for this era, the CX's chassis design and advanced (for its time) safety features offered a degree of passive safety.
Active Safety Features:
Hydropneumatic self-leveling suspension for stable handling, powerful hydraulic brakes, Diravi self-centering steering (reduces steering wheel kickback).
Passive Safety Features:
Integrated crumple zones, reinforced safety cell, laminated front windscreen, 3-point seatbelts (front), 2-point seatbelts (rear).
Oil Change Interval:
Typically every 10,000 km or 12 months, using appropriate grade oil (e.g., 10W-40 or 15W-40 depending on climate and engine).
Hydropneumatic Fluid Change:
Recommended every 60,000 km or 3 years for LHM (Citroën hydraulic fluid).
Engine Oil Capacity:
Approx. 4.0 - 4.5 litres (for 2.0L/2.2L petrol).
Cooling System Capacity:
Approx. 7.5 - 8.5 litres (depending on engine).
Hydropneumatic System Fluid:
LHM (Liquide Hydraulique Minéral) - Green fluid.
Common Wear Items:
Hydropneumatic suspension spheres (loss of pressure, 'sagging'), front suspension arm bushings, steering rack gaiters, exhaust system corrosion, electrical contact issues (especially earth points).
Engine Specific Issues:
Oil leaks from engine seals, potential for camshaft wear on higher mileage engines, early fuel injection system calibration.
Hydraulic System Issues:
Leaking hydraulic lines, pump wear, slow ride height adjustment, hardening of rubber seals.
Citroen Heritage:
Citroën is renowned for its innovative and avant-garde automotive engineering, particularly its pioneering work in suspension and aerodynamics.
Cx Evolution:
The CX was introduced in 1974 as the successor to the iconic DS. The Series 2, launched in 1985, featured significant updates including revised dashboard, improved aerodynamics, updated engines, and revised suspension components.
Production Period:
1974-1991 (Series 2: 1985-1991).
