Engine Family 1:
PSA XU series (Petrol)
Engine Variants Petrol:
e.g., XU7 (1.8L), XU9 (1.9L), XU10 (2.0L) - Specific displacements and power outputs vary by market and trim.
Engine Family 2:
PSA XUD series (Diesel)
Engine Variants Diesel:
e.g., XUD7 (1.8L Diesel), XUD9 (1.9L Diesel), XUD11 (2.1L Diesel).
Power Output Range:
Typically 75 PS to 135 PS depending on engine variant.
Torque Range:
Varies by engine; Diesel variants generally offer higher torque at lower RPMs.
Petrol Injection:
Multi-Point Fuel Injection (MPI) for most petrol engines.
Diesel Injection:
Indirect injection (IDI) for XUD series, with rotary or inline injection pumps (e.g., Bosch VE).
Manual Transmission:
5-speed manual gearbox (e.g., BE series).
Automatic Transmission:
4-speed automatic transmission (e.g., AL4 sourced from PSA/Renault JV).
Clutch Type:
Hydraulically operated dry single-plate clutch.
Gear Ratios:
Specific ratios for each engine/transmission combination are detailed in the manual.
Transmission Fluid Spec:
Manual: API GL-4, viscosity typically 75W-80 or 75W-90. Automatic: ATF Dexron III or equivalent.
Length:
Approx. 4,510 mm (177.6 in)
Width:
Approx. 1,750 mm (68.9 in)
Height:
Approx. 1,370 mm (53.9 in) - Varies with suspension height.
Curb Weight Range:
Approx. 1,300 - 1,500 kg (2,866 - 3,307 lbs) depending on engine and equipment.
Gross Vehicle Weight:
Refer to vehicle's VIN plate for specific GVWR.
Euro Ncap Rating:
The Xantia was tested by Euro NCAP in 1997, achieving a 2.5-star rating for front occupant protection. (Note: Testing standards and vehicle configurations vary over time.)
ABS:
Optional or standard on higher trims for Anti-lock Braking System.
Brake Distribution:
Electronic Brake Force Distribution (EBFD) or similar proportional braking systems may be fitted.
Airbags:
Driver airbag standard, passenger airbag optional on some early models.
Seatbelts:
Pre-tensioning seatbelts on front seats.
Oil Change Interval Petrol:
Typically every 10,000-15,000 km (6,000-9,000 miles) or 12 months, whichever comes first (refer to manual for specific engine variant).
Oil Change Interval Diesel:
Typically every 7,500-10,000 km (4,500-6,000 miles) or 12 months.
Timing Belt Replacement:
Crucial for XU engines; typically every 80,000-120,000 km (50,000-75,000 miles) or 5-7 years. Critical to follow manual's recommendation to avoid catastrophic engine damage.
Engine Oil Spec:
Petrol: 5W-40 or 10W-40 API SL/SM. Diesel: 10W-40 API CF/CG-4. Consult manual for exact viscosity and ACEA standards.
Coolant Spec:
OAT (Organic Acid Technology) type antifreeze, typically pink or orange, with a 50/50 mix with deionized water. Citroën part number likely: GVA 62110 or equivalent.
Hydropneumatic Fluid:
LHM Plus (Citroën hydraulic mineral oil), typically green. Citroën part number: GVA 62110 or equivalent.
Suspension Spheres:
Hydropneumatic suspension spheres can lose pressure over time, leading to a harsh ride or 'bottoming out'. Replacement is a common maintenance item.
Anti-Pollution Filters:
Diesel models (XUD) can have issues with the anti-pollution filter (catalytic converter in some cases, or simpler exhaust silencer/catalyst unit) clogging, especially with short journeys.
Electrical Connectors:
Corrosion or poor connections in electrical connectors, particularly in the engine bay and under the dashboard, can cause intermittent faults.
Corrosion:
As with many cars of this era, particularly in certain climates, rust can be an issue on wheel arches, sills, and suspension components.
Citroen Legacy:
Citroën has a long history of innovative automotive engineering, particularly with suspension systems (e.g., 2CV, DS, CX).
Xantia Placement:
The Xantia succeeded the Citroën BX and was part of Citroën's effort to regain market share in the family car segment, focusing on comfort and technology.
Xantia Design:
Designed by Bertone, it featured aerodynamic styling and further development of Citroën's hydropneumatic suspension technology (Hydractive II).
Production Years:
1993 - 2002
Manufacturing Locations:
Primarily Rennes, France, and also manufactured under license in other regions.
