Approximately 99 hp (CX 25 D Turbo) to 136 hp (CX 25 GTI).
Injection Carburetion:
Carbureted (e.g., Weber) and fuel injection (e.g., Bosch L-Jetronic) systems depending on model and year.
Crash Safety:
Designed with passive safety in mind, featuring deformable body structures, padded interiors, and seatbelts. Specific crash test ratings from the era are limited by modern standards.
Braking System:
Powerful hydropneumatic-assisted braking system with front ventilated discs and rear solid discs (or drums on some early models).
Interior Design:
Deformable steering column, energy-absorbing dashboard, and deep-recessed controls.
Radio Options:
Factory-fitted radios and cassette players were common options, with basic tuning and volume controls.
Cruise Control:
Available as an option on higher-spec models, especially later versions.
Original Features:
Centralized locking, power windows (on higher trims), and adjustable steering column were advanced features for their time.
Oil Change Interval:
Typically every 5,000 km to 10,000 km, depending on driving conditions and oil type specified in the manual.
Hydropneumatic Fluid Change:
Recommended periodic checks and fluid replacement (LHM - Liquide Hydraulique Minéral) for the suspension and braking systems.
Engine Oil:
Refer to manual for specific viscosity grades (e.g., 10W-40, 20W-50) based on ambient temperature and engine type. Often API SF or SG rated.
Hydropneumatic Fluid:
Citroën LHS 2 (later LHM - Green fluid) is critical for the hydropneumatic system. Manual will specify exact type and capacity.
Brake Fluid:
DOT 3 or DOT 4, shared with the clutch system in some configurations. Manual will detail correct type and change interval.
Common Problems:
Hydropneumatic system leaks (e.g., suspension height drop), electrical gremlins, rust in common areas, wear of suspension spheres, and specific engine component issues depending on model.
Common Problems Hydropneumatic:
Hydropneumatic spheres require periodic replacement or recharging. Pump wear and seal failures can also occur.
Filter Part Numbers:
Manual will contain specific part numbers for oil filters, fuel filters, air filters, and hydropneumatic system filters for various engine options.
