Torque Range:

Approx. 150 Nm to 210 Nm depending on engine and fuel type.

Fuel Delivery:

Likely either carbureted (e.g., Solex, Weber) for base models or Bosch L-Jetronic/K-Jetronic fuel injection for higher-spec models.

Cooling Type:

Liquid-cooled, front-mounted radiator with electric fan.

🔧 Transmission

Standard Transmission:

Likely a 5-speed manual transmission for many models.

Optional Transmission:

Citroen's 3-speed or 4-speed automatic transmission (e.g., C-Matic, ZF 4HP22 on some models).

Transmission Features:

Remote gearshift linkage for manual transmissions, smooth engagement for automatics.

🛡️ Safety Features

Crash Test History:

Euro NCAP did not exist in its current form during the CX's primary production run. However, the car was designed with safety in mind for its era, featuring a robust steel chassis and advanced passive safety features.

Active Safety:

Powerful hydraulic disc brakes on all wheels, DIRAVI steering system which stiffens at speed for stability.

Passive Safety:

Impact-absorbing steering column, reinforced body structure, laminated windscreen, often equipped with front seat belts, optional rear belts.

💡 Technology Features

Infotainment System:

Basic for its era; typically featured an analog radio with cassette player, manual antenna adjustment, and basic speaker systems.

Driver Assistance:

DIRAVI (Direction par Rappel Asservi) speed-sensitive steering was a key technological feature, providing lighter steering at low speeds and increased resistance at higher speeds for stability.

Connectivity Features:

No modern connectivity features like Bluetooth or USB ports. Basic accessory power outlet.

🔧 Maintenance

Oil Change Interval:

Typically every 7,500 - 10,000 km (4,500 - 6,000 miles) or annually, depending on usage and oil type.

Timing Belt Interval:

For applicable engines (e.g., Douvrin), typically 60,000 - 80,000 km (37,000 - 50,000 miles).

Engine Oil Type:

API SF/SG or equivalent, viscosity grade typically 10W-40 or 15W-50, depending on climate. Refer to manual for exact spec.

Hydropneumatic Fluid:
