The Citroën Xantia (pronounced "Zan–ti–a") is a large family car classified in the D-segment, manufactured by the French automaker Citroën and styled by Gruppo Bertone. Introduced in December 1992, production took place in France until 2001, with a significant redesign unveiled in late 1997.

A highlight of the range, the Citroën Xantia Activa V6, achieved a record speed in the moose test due to its sophisticated active anti-roll bar system, surpassing competitors such as the Porsche 997 GT3 RS.

Over its nine-year production span at the PSA Rennes Plant, Citroën built more than 1.2 million Xantias. The model was replaced by the Citroën C5 in 2001; however, remaining inventory continued to be sold in France until October 2002.

From 2001 until 2010, licensed manufacturing of the Xantia was carried out by SAIPA in Tehran, Iran, contributing an unspecified quantity to the overall production figures.

Name

The designation "Xantia," similar to other Citroën vehicles like Athena and Pallas, draws inspiration from ancient Greek origins. It is derived from Xanthos, meaning golden or blond in the Greek language. Xanthos was an ancient city in Lycia, famed for the Xanthian Obelisk, a bilingual artifact dating back to the era of the Persian Achaemenid Empire found among its ruins.

History

Replacing the earlier Citroën BX, the Xantia served as a bridge between small and large family cars, competing directly with mainstream mid-size models such as the Ford Mondeo and Opel Vectra/Vauxhall Cavalier. Manufactured in France from November 1992 through October 2002, it maintained a strong market presence throughout nearly ten years, including a refresh introduced in December 1997.

In response to critiques of the conservative Citroën ZX, Citroën imbued the Xantia with traditional engineering innovation, notably preserving its hallmark hydropneumatic suspension system first developed on the Citroën DS. The initial launch featured a hatchback (Berline), followed by an estate (Break) variant produced by Heuliez starting September 1995.

Aligning with PSA Group’s platform-sharing strategy, the subsequent Peugeot 406 utilized the same floorpan, structural framework, and engine options as the Xantia but employed conventional spring suspension instead of Hydractive technology.

Within the United Kingdom, although it did not exceed sales of leading models like the Ford Mondeo or Vauxhall Vectra, the Xantia established a firm foothold within the business car market segment, bolstering Citroën’s presence.

1998 facelift

The facelift introduced at the end of 1997 marked a clear distinction between Mark 2 Xantias (1998–2001) and their Mark 1 predecessors (1993–1997). Changes included moving the grille onto the bonnet, fitting body-colored bumpers, and updating the dashboard design, all aimed at enhancing competitiveness in the mid-size segment.

Xantia Activa

At the pinnacle of Citroën’s Xantia range was the Activa, launched toward the end of 1994. Its production spanned from spring 1995 until autumn 2001, with just over 18,000 units produced.

Taking its name from the Citroën Activa concept vehicle, this model’s defining attribute was its capability to corner without any chassis roll due to advanced active suspension technology. Beyond featuring Hydractive II, it incorporated undercarriage stabilization known as AFS or SC.CAR (Système Citroën de Contrôle Actif du Roulis), marking it as the first production car equipped with an active cross-stabilizer system. This technology drastically reduced lateral body lean (between −0.2° and 1°) through hydraulic cylinders acting on cross-stabilizer bars, allowing lateral accelerations up to 1.2 g while delivering superior ride comfort and improved safety. Additionally, early X1 models included pneumatically adjustable side-rail seats reinforced for enhanced support.

Activa active anti-roll bars

Launched in 1994, the Activa system enhanced the Hydractive II suspension by incorporating two additional spheres and electronically managed hydraulic cylinders, effectively minimizing body roll during cornering.

Moose test

Thanks to its active anti-roll bar technology, the Citroën Xantia V6 Activa set a moose test record at , a critical emergency maneuvering standard established by Teknikens Värld magazine. This achievement remained unbeaten for 26 years until the Porsche Cayman GT4 RS Manthey surpassed it. The second-best result was recorded by a Nissan Qashqai DIG-T 160 Acenta, achieving .

A TikTok video comparing a 1996 Xantia with a 2021 BMW M4 Competition demonstrated the Xantia’s superior moose test capabilities—successfully negotiating the test at 73 km/h without displacing cones, whereas the M4 had to reduce speed to 29 km/h and knocked over cones.

Detailed description of AFS / SC.CAR

The system utilized relatively robust diagonal transverse stabilizer bars (28 mm at the front, 25 mm at the rear) linked to wheel hubs through differential hydraulic cylinders. These cylinders were operated by a valve mechanically connected to the front cross joints via connecting rods.

During lateral body roll, opposing wheel movements activated the control valve, producing hydraulic pressure proportional to the roll force. This pressure adjusted the cylinders against the stabilizer bars’ resistance, applying horizontal force on the vehicle body and significantly reducing tilt during cornering up to approximately 0.6g lateral acceleration with minimal side lean (ranging from −0.2° to 0.5°). Beyond that limit, the cylinders returned to a neutral position, permitting up to about 1° of tilt similar to that found in sports cars.

Functioning independently from the Hydractive II suspension system, these active stabilizers ensured consistent suspension behavior even under extreme cornering conditions, improving grip beyond traditional configurations. While driving straight, a solenoid valve connected a gas-charged spring sphere into the hydraulic circuit, effectively softening stabilizer stiffness for enhanced ride comfort and damping minor suspension oscillations.

Activa engines

The Xantia Activa offered petrol engine options such as the 2.0i 16V (available in 97 kW/132 hp and 110 kW/150 hp variants), 2.0i Turbo CT (108 kW/147 hp), and a 3.0i V6 (140 kW/190 hp). Diesel choices included the 2.1 Turbo D12 (80 kW/109 hp) and the 2.0 HDi (80 kW/109 hp).

Notable Activa-specific features comprised a factory-fitted rear spoiler, "Venise" alloy wheels, body-colored bumpers (on early models), a black roof canopy depending on production year, specially designed front seats with distinctive side bolsters, and an Activa badge replacing traditional engine emblems.

Hydraulic suspension

The Xantia was Citroën’s final model to utilize LHM mineral hydraulic fluid; later models such as the C5 transitioned to LDS fluid. It also preserved the unified hydraulic circuit for suspension, braking, and steering systems—a characteristic innovation dating back to the Citroën DS.

Available hydraulic configurations included:

• Hydropneumatic suspension (5 spheres)
• Hydractive 2 suspension (7 spheres)
• Hydropneumatic anti-sink suspension (6 spheres)
• Hydractive 2 anti-sink suspension (8 spheres)
• Activa active suspension SC.CAR (10 spheres)

Hydractive

A significant technological innovation was the Hydractive II suspension system, managed by a computer, which improved ride quality by utilizing additional spheres for a softer experience during regular driving and firmer response when braking or cornering.

Additionally, these versions featured a programmed self-steering rear axle, initially implemented on the ZX and later on the updated XM, which enhanced handling by adjusting the rear wheels to follow the front wheels on bends.

Engines

The Xantia's engine lineup mainly consisted of PSA Group's XU series petrol engines in 1.6, 1.8, and 2.0-liter capacities. This included a 16-valve 2.0-liter engine for the VSX model and turbocharged variants introduced from 1995 onwards. In 1997, a premium 3.0-liter V6 engine was added, paired with Activa suspension; production of this version was limited to under 2,600 units.

Diesel options focused on PSA's widely used XUD turbodiesels at 1.9 liters with power outputs ranging from 71 to 92 hp, alongside a larger 2.1 TD engine producing 109 hp. The introduction of HDi direct injection diesels in 1998 brought enhancements such as better throttle response and quieter cruising at speeds up to 118 mph.

In the UK market, Activa models were equipped with the XU10 2-liter turbocharged engine shared with the Citroën XM 2.0CT and Peugeot 605 SRi, delivering a refined output of 150 bhp and torque of 171 lb-ft.

Iranian production

Between 2001 and 2010, the Citroën Xantia was manufactured in Iran in four distinct versions, all equipped with a five-speed manual transmission and a five-door liftback design. This production marked SAIPA's return to assembling Citroën vehicles since the era of the Citroën Dyane Jian (1967–1980).

On February 18, 2000, an agreement was signed renewing the collaboration, appointing SAIPA as a regional export center for the Xantia targeting markets in the Middle East, Central Asia, Russia, and Ukraine. In 2001, out of a planned 12,000 units, approximately 9,500 were slated for export, with local components comprising at least 40% of the parts.

SAIPA considered the Xantia among its most successful offerings in Iran’s automotive sector. Production ended in 2010 due to difficulties sourcing parts from France and Citroën. Precise production numbers have not been publicly disclosed.

Xantia Facelift or Xantia 2: Nearly identical to the 2000 SX regarding engine specifications, transmission, and equipment; however, front and rear bumpers were redesigned internally by Saipa’s engineering team.

Chinese production

Between 1996 and 1997 in Huizhou, Guangdong province, both the Citroën Xantia and XM were assembled from CKD kits but with very limited quantities. To avoid steep import taxes, vehicles arrived mostly complete with minimal local assembly. Both models were marketed under the Fengshen brand as XM variants named Fengshen Xietuolong XM.
