Product Code Database
The Citroën Xantia (pronounced "Zan–ti–a") is a large family car (D-segment) produced by the French automaker Citroën, and designed by Gruppo Bertone. Presented to the press in December 1992, the car was produced between 1992 and 2001 in France, with a facelift in the end of 1997.
The Citroën Xantia Activa V6 used to hold the record speed () through the moose test maneuver, due to its active anti-roll bars. This test is conducted by the magazine Teknikens Värld's, as a test of avoiding a moose in the road. The second place car, Porsche 997 GT3 RS was able to manage .
Citroën produced 1,216,734 Xantias during its nine years of production at the PSA Rennes Plant. The Xantia was replaced with the Citroën C5 in 2001, although in its native France stock models continued to be offered as a cheaper alternative until October 2002.
Production of the Xantia at SAIPA, Tehran Iran from 2001 to 2010 resulted in an undisclosed number of additional units.
"Xantia" is derived from Xanthos, mean golden or blond in Greek language. Xanthos is name of an ancient Lycian city (meaning "golden city") in ancient Lycia region. The name is also known for Xanthian Obelisk, An bilingual Obelisk from Persian Achaemenid Empire era found in ruins of Xanthos city.
The letter X was used in many Citroën models of this era. Citroën worked closely with Michelin, who were promoting their 'X' brand of tyres.
The car was built from November 1992 to October 2002 in France, totalling almost ten years, including the facelift in December 1997.
It signalled that Citroën had learned from the reception given to the staid Citroën ZX, introduced two years earlier, and criticised by contemporary journalists for its lack of traditional Citroën flair, in engineering and design. Citroën addressed these concerns in the Xantia.
The Xantia also used the traditional Citroën hydropneumatic suspension system, which was pioneered by the older DS. It was initially only available as a hatchback (notchback) (Berline), but an station wagon (station wagon) (Break) version, built by Heuliez, appeared in September 1995.
Inline with PSA Group policy, the Peugeot 406, launched two years later, used the same floorpan, core structure and engines as the Xantia. The Hydractive suspension system was not carried over, and the 406 utilised a more traditional spring suspension.
Sales in the United Kingdom were strong, and even though it was never able to match the volume of England favourites, such as the Ford Mondeo or Vauxhall Vectra, the car did help Citroën establish a strong foothold in the business car market in the United Kingdom.
The name refers to the Citroën Activa showcar. The distinguishing feature of the Activa was the ability to drive around curves without any chassis roll. This technology is more broadly known as active suspension.
This lack of roll is achieved by active chassis intervention. In addition to Hydractive II, Activa also had undercarriage stabilization (AFS), in French SC.CAR = Systeme Citroën de Contrôle Actif du Roulis, which was the first standard-fitted, active cross-stabilizer in automobile construction. With this system, the lateral inclination could be reduced to a minimum (−0.2 ° to 1 °) by means of mechanical control with hydraulic cylinders acting on the cross-stabilizer bars. This technique enabled (according to the manufacturer's specifications) with optimal road grip transverse accelerations of up to 1.2 g and despite this also offered an above-average high suspension comfort and thus a safer road position. Compared to the standard models, Activa had seats with reinforced side rails, which on the first series (X1) were also pneumatically adjustable.
A TikTok video compared a 1996 Citroën Xantia to a 2021 BMW M4 Competition in the moose test: The Xantia was able to pass the obstacles at without flipping a single traffic cone, whereas the M4 had to slow down to , while still knocking down three cones in the process.
These cylinders were connected to a control valve, which was operated directly by the front cross joints with connecting rods over a spring-handle mechanism. The occurring rolling moment (side slope) had the opposite effect on the cross joints - one wheel springs in and the other out. Thereby, the control valve (inclination corrector) was pulled out / pushed in by means of the connecting rods in a direction out of its rest position (straight ahead), whereby a pressure proportional to the rolling moment was formed in the hydraulic cylinders.
Thereby the hydraulic cylinders changed position and acted against the bias of the cross stabilizer. They "pressed" the body over the cross-stabilizer bars against the rolling torque further horizontally, enabling cornering with up to 0.6g transverse acceleration with −0.2 to 0.5° lateral inclination. From 0.6g transverse acceleration, the cylinders returned to the starting position, from which the Xantia Activa tilted up to 1° in the curve until the curve limit area was reached, which corresponded to the value of a sports car with a correspondingly tighter tuning.
As these active roller stabilizers worked independently of the Hydractive II undercarriage, the suspension could be almost completely maintained even at extreme cornering, giving a significantly better road position in these situations than with conventional wheel suspensions. When driving straight ahead, a solenoid valve was operated by the control unit for the Hydractive suspension, which connected an additional spring ball in the hydraulic control circuit of the cylinder. Thereby, the stiffness of the tightly tuned stabilizer bars could be minimized "virtually" by gas filling the spring ball to reduce the movements and increase the comfort. Likewise, they had a damping effect on the control circuit, so that there were no undesired oscillations during straight-ahead driving due to suspension-related, short-term operation of the inclination corrector.
Petrol: 2.0i 16V 97 kW (132 hp), 2.0i 16V 110 kW (150 hp), 2.0i Turbo CT 108 kW (147 hp) and 3.0i V6 140 kW (190 hp). Diesel: 2.1 Turbo D12 80 kW (109 hp) and 2.0 HDi 80 kW (109 hp).
The Activa could be recognized by the standard-fitted rear spoiler, the "Venise" alloy wheels, the car-painted bumpers (on the first series), the black roof canopy (depending on the year of construction), special front seats with distinctive side members and the Activa logo instead of engine displacement badge.
The Xantia also was the last Citroën vehicle to use a common hydraulic circuit for suspension, brakes and steering like the pioneering Citroën DS.
The Xantia had several variants of the Hydraulic system:
This used extra suspension spheres to allow a soft ride in normal conditions, but taut body control during hard braking, acceleration or cornering.
These models feature an innovation first seen on the ZX, and then subsequently fitted to the facelifted XM, a programmed self steer rear axle. On sweeping curves and tight bends alike, the rear wheels turn in line with the front wheels, sharpening responses and adding to driver pleasure. Citroën - Xantia
The popular XUD turbodiesel units in 1.9 (turbocharged: , low pressure turbo: , or not: 71 hp) displacement proved to be the best selling engine.
The biggest diesel was a 2.1 TD with . In 1998, PSA introduced the HDi direct injection turbodiesel (in two versions: , and intercooled 109 PS). For an economical diesel engine, the HDi offered the kind of throttle response normally seen in a gasoline engine and quiet high speed cruising at a top speed of .
United Kingdom models of the Activa came fitted with a XU10 2 litre turbocharged engine also fitted to the Citroën XM 2.0CT and Peugeot 605 SRi. It produced 150 bhp and 171 lb ft of torque and was a 'low-blow' type for smooth power delivery rather than outright bhp.
The February 18, 2000 contract, that renewed the relationship, called for SAIPA to serve as a center for exporting Xantia to the Middle East, Central Asia, Russia and Ukraine. In 2001, 9,500 out of a total 12,000 cars to be made in Iran, were expected to be sent abroad for being sold. At least 40% of parts would be made in Iran.
According to SAIPA, The Xantia was one of the best products produced in the history of car manufacturing in Iran. Production of the Xantia ended in 2010 due to the lack of spare parts from France and Citroën.
Full production figures of the Xantia in Iran are unknown.
