Engine Families:
TU (petrol) and XU (diesel) series engines. Petrol engines included 1.1L, 1.4L, 1.6L, and 1.8L/1.9L variants. Diesel engines typically 1.9L naturally aspirated and turbocharged.
Typical Power Range:
Petrol: 55 hp to 125 hp (for performance variants like the ZX Volcane/16v). Diesel: 64 hp to 90 hp.
Torque Figures:
Varies significantly by engine, e.g., 1.4L petrol ~110 Nm, 1.9D ~115 Nm, 1.9 16v petrol ~175 Nm.
Injection Carburetion:
Carbureted on early base models, progressing to multi-point fuel injection (MPI) on later petrol variants. Diesels were direct injection or indirect injection with mechanical pumps.
Common Petrol:
TU3 (1.4L), TU5 (1.6L), XU7 (1.8L), XU9 (1.9L).
Common Diesel:
XUD7 (1.8L), XUD9 (1.9L).
Manual Transmission:
Typically a 5-speed manual transaxle was standard across most models.
Automatic Transmission:
A 3-speed or 4-speed automatic transmission was available as an option on some petrol engine variants.
Clutch Type:
Hydraulically actuated dry single-plate clutch.
Gearbox Codes:
Various BE and MA series gearboxes used. Specific ratios depend on engine and model. Manual will detail these.
Body Styles:
3-door hatchback, 5-door hatchback, and estate (ZX Break/Volcane Wagon).
Typical Length:
Approx. 4.05 - 4.25 meters depending on body style.
Curb Weight Range:
Approx. 1000 kg to 1250 kg depending on engine and specification.
Towing Capacity:
Typically around 1000-1200 kg braked towing capacity, depending on engine and model. Refer to vehicle's VIN plate or manual.
Crash Test Results:
Euro NCAP testing was not standardized during the early part of its production. Later models would have undergone testing, with results generally in line with contemporary European compact cars. Specific scores are difficult to ascertain without direct reference to a particular model year's testing.
Headlight Aim:
Specifications for headlight aiming adjustment provided.
Braking Systems:
ABS was an option on higher trims and later models. Ventilated front discs, solid rear discs or drums were common.
Airbags:
Driver's airbag became standard on later models and optional on earlier ones. Passenger airbag was a rarer option.
Seatbelts:
Pre-tensioner seatbelts were introduced on some models.
Audio System:
Factory fitted radio/cassette players, often with basic speaker systems. CD players became available on later, higher-spec models.
ABS Availability:
Optional on most models, standard on later top-spec versions or performance variants.
Connectivity Features:
Limited by era. Primarily focused on basic vehicle operation. No integrated Bluetooth or advanced smartphone connectivity.
Oil Change Interval:
Typically 7,500 to 10,000 miles or 12 months, depending on engine type and driving conditions. Refer to manual for exact specifications.
Timing Belt Replacement:
Crucial for TU and XU engines. Intervals vary, often 60,000 - 90,000 miles or 4-5 years. Refer to manual for specific engine code.
Engine Oil Grade:
Commonly 5W-40 or 10W-40 for petrol, and 10W-40 or 15W-40 for diesel. API SJ/CF or higher specification required. Manual will list exact grades and capacities.
Coolant Type:
Ethylene glycol-based coolant with anti-corrosion inhibitors. Citroën recommends specific grades (e.g., Type D). Manual will specify capacity and type.
Brake Fluid Type:
DOT 3 or DOT 4 hydraulic fluid. Must be replaced periodically (e.g., every 2 years) due to hygroscopic nature.
Gearbox Oil Grade:
Manual transmission: Typically a GL-4 75W-80 or 75W-90 synthetic gear oil. Automatic transmission: Specific ATF fluid (e.g., LT71141 for some variants). Manual will specify.
Common Wear Items:
Front suspension arms/bushings, rear torsion bars (seizing/wear), exhaust systems, ignition components, clutch hydraulics, rust on sills and wheel arches.
Engine Specific:
TU engines generally reliable, XU diesels known for longevity but can suffer from injector pump issues or glow plug failures. Head gasket issues can occur with overheating.
Citroen Philosophy:
Citroën's heritage is built on innovation, avant-garde design, and a focus on ride comfort and road holding. The ZX continued this tradition with its unique suspension and styling.
Key Milestones:
Launched in 1991 as a replacement for the aging Visa and a more mainstream offering than the BX. Saw facelifts and updates throughout its production run, including engine upgrades and trim level revisions. Performance variants like the ZX Volcane and 16v were key to its sporting image.
Performance Variants:
ZX Volcane (1.9L 8v/16v petrol) and ZX Aura (1.8L 16v petrol) offered sporty trims with enhanced handling and power.
Manufacturing Locations:
Primarily manufactured in France, with potential for assembly in other European plants.
