⚙️ Engine Specifications

Engine Type:

Inline-4 Cylinder, Front-Wheel Drive

Engine Displacement:

Typically 1995cc (2.0L) for standard models, with 2175cc (2.2L) and 2375cc (2.4L) DG & DS engines (including fuel injection) available in higher trims or later iterations of Series 1.

Horsepower Range:

Approx. 90-110 hp for 2.0L, up to 126 hp for 2.4L fuel-injected variants.

Torque Range:

Varies by engine, with larger engines offering more torque for comfortable cruising.

Fuel Delivery:

Carburetor (e.g., Weber, Solex) for most 1984 models, with Bosch L-Jetronic fuel injection available on higher-spec models (e.g., CX 2400 GTI).

Ignition System:

Typically electronic ignition with distributor.

🔧 Transmission

Transmission Type Std:

4-speed Manual

Transmission Type Opt:

3-speed or 4-speed Automatic (e.g., Citroen-Maserati C-Matic, ZF 3HP22)

Transmission Features:

Front-wheel drive transaxle layout, designed for compact packaging and weight distribution.

📐 Dimensions

Length:

Approx. 4640 mm (182.7 in)

Width:

Approx. 1770 mm (69.7 in)

Height:

Approx. 1370 mm (53.9 in)

Wheelbase:

Approx. 2900 mm (114.2 in)

Curb Weight:

Approx. 1300-1400 kg (2866-3086 lbs) depending on engine and equipment.

🛡️ Safety Features

Crash Test Ratings:

No standardized global crash test ratings like modern NCAP existed for 1984 models, but design principles focused on crumple zones and cabin integrity.

Active Safety:

Powerful disc brakes on all wheels, independent suspension, front-wheel drive for improved traction.

Passive Safety:

Reinforced passenger cell, padded dashboard, seat belts (front typically standard, rear optional).

💡 Technology Features

Audio System:

Factory-fitted radio and cassette player, often with basic speaker configurations.

Steering System:

DIRAVI (Direction à rappel asservi) system - a speed-sensitive power steering with a strong self-centering effect that stiffens at higher speeds.

Connectivity Features:

Limited by era; primarily mechanical and electrical systems, no modern digital connectivity features.

Other Innovations:

Hydropneumatic suspension with adjustable ride height, advanced aerodynamics for its time, central locking (optional/depending on trim).

🔧 Maintenance

Oil Change Interval:

Typically every 5,000 - 7,500 km (3,000 - 4,500 miles) or 6-12 months, depending on usage and oil type.

Major Service Interval:

Refer to manual for specific intervals for timing belt (if applicable to engine variant), transmission service, brake fluid flush, and suspension fluid checks.

Engine Oil:

Refer to manual; typically API SG or SF rated, viscosity grades like 10W-40 or 20W-50 depending on climate.

Hydropneumatic Fluid:

LHM (Liquide Hydraulique Minéral) - Citroen's proprietary mineral-based hydraulic fluid. Crucial to use the correct fluid type.

Brake Fluid:

DOT 3 or DOT 4, depending on the specific hydraulic system specifications.

Transmission Fluid Auto:

Dexron-II or equivalent for automatic transmissions. Manual transmission uses gear oil.

Common Issues:

Hydropneumatic system leaks (e.g., spheres, hoses, seals), electrical gremlins, rust in key structural areas, wear on the characteristic DIRAVI self-centering steering system, aging rubber components.

Maintenance Importance:

Proactive maintenance of the hydropneumatic system is paramount to ensuring ride quality and longevity, and preventing costly repairs.
