Citroen Xantia: The Hydractive Family Car With an Active Roll Trick

The Citroen Xantia was a large family car designed by Bertone and presented to the press in December 1992. Built in France until 2001, it carried the hydropneumatic tradition forward, and its top Activa version used active roll control to keep the body almost flat in corners.

What was the Citroen Xantia?

The Xantia replaced the Citroen BX, which had straddled the small and large family car segments. It was pitched more squarely at the mainstream, where it competed with the Ford Mondeo, the Opel Vectra and the Vauxhall Cavalier. Production ran from 1992 to 2001 in France, with a facelift at the end of 1997.

The name comes from Xanthos, the Greek word for golden or blond, and it is also linked to an ancient Lycian city. Citroen used the letter X on several models of the period, a styling habit that fitted its tyre partner, whose X brand was promoted at the same time.

The first generation, built from 1993 to 1997, carried its grille integrated into the bodywork. The Mark 2 cars built from 1998 to 2001 had the grille attached to the bonnet, and the facelifted car also gained body-coloured bumpers and a revised dashboard.

The early 1990s were a crowded period for mid-size family cars. Buyers compared the Xantia with German and British rivals on space, refinement and value, so Citroen needed a car that could hold its own against established names rather than relying on eccentric engineering alone.

A large French family car that carried the hydropneumatic tradition into the late nineties and then gave one version a near-flat cornering trick.

Why was the Xantia important to Citroen?

The Xantia was Citroen's answer to criticism of the ZX, which had been introduced two years earlier and was judged to lack the traditional Citroen flair in engineering and design. The Xantia showed that the company had listened, and it returned to the hydropneumatic suspension that had made earlier models distinctive.

Citroen built 1,216,734 Xantias at the PSA Rennes plant during its nine years of production. Estate versions followed, with a Break built by Heuliez arriving in September 1995. Sales held up well in Britain, where the car helped Citroen win a stronger place in the business car market.

The Peugeot 406 later used the same floorpan, core structure and engines, but it dropped the Hydractive system in favour of conventional springs. That decision separated the two cars' suspension designs, even though they shared most of their mechanical base.

Buyers who knew the company's history expected the hydropneumatic ride from a Citroen, and the Xantia delivered it in a more conventional package. The car sat between the old BX and the more mainstream models that followed, which is why it is often remembered as a bridge between two eras.

Its success in the business market shows how a car with a distinctive character can still earn fleet orders when its engineering is sound.

What was Hydractive II, and why did it matter?

Hydractive II was the computer-controlled version of the hydropneumatic self-levelling suspension, and it was available on the more expensive Xantia models from launch. It used extra suspension spheres to give a soft ride in normal use while keeping the body under control during hard braking, acceleration or cornering.

Its hydraulic layout varied by model. The Xantia used hydropneumatic systems with 5, 6, 7, 8 and 10 spheres depending on the version, with the anti-sink variants adding extra valves and spheres to stop the car settling after it had been parked.

The Xantia was also the last Citroen to use LHM, a green mineral oil, and the last to run suspension, brakes and steering from one common hydraulic circuit as the pioneering DS had done. Later cars such as the C5 switched to a different fluid.

Hydraulic systems demanded regular attention, and owners who kept the cars for years learned to respect the sensitive electronics and fluid levels. That is one reason the Xantia still attracts enthusiasts who enjoy hands-on maintenance.

Engineers at the time saw the hydraulic approach as a way of separating ride comfort from body control, a goal that conventional springs and dampers could not match at the same cost.

What did the Activa add to the Xantia?

The Activa was the top model in the Xantia range. It was introduced at the end of 1994, and from spring 1995 to autumn 2001 just over 18,000 were built. Its key feature was the ability to take bends without visible chassis roll, a system that is now called active suspension.

The Activa used a system called SC.CAR, short for Systeme Citroen de Controle Actif du Roulis. It was the first standard-fitted active cross-stabiliser in a production car, with hydraulic cylinders working against the anti-roll bars. Citroen claimed up to 1.2 g of transverse acceleration with roll held to a minimum.

Activa models were easy to spot. They had a standard rear spoiler, Venise alloy wheels, a black roof canopy on some years, special front seats with reinforced side rails and an Activa badge in place of the engine size. The seats on the first series could also be adjusted pneumatically.

The Activa's roll-control hardware added weight and complexity compared with a standard Xantia, but the trade-off was a car that stayed level when most family cars would lean noticeably. That combination of comfort and control was the point of the model. Modern cars still limit roll, though they do it with electronic systems rather than the hydraulic cylinders that the Activa relied on.

How good was the Activa at the moose test?

The Xantia Activa V6 held the record for the moose test at 85 km/h (53 mph), a manoeuvre run by the Swedish magazine Teknikens Varld. The active anti-roll bars let the car stay level through the swerve, which made it faster than rivals in that test for many years.

Results like these say more about handling than about straight-line speed. A family car that stays level through a sudden swerve can avoid trouble that a conventional car would struggle with, which is why the test became a popular talking point.

That record fell after 26 years to the Porsche Cayman GT4 RS Manthey. The Nissan Qashqai DIG-T 160 Acenta managed 84 km/h (52 mph) in the same test, so the Xantia was well ahead of the mainstream crossover.

Video comparisons also circulated online, including one that matched a 1996 Xantia against a 2021 BMW M4 Competition. The Xantia passed the cones at 73 km/h (45 mph) without knocking one over, while the M4 had to slow to 29 km/h (18 mph) and still hit three cones.

Videos like these reached audiences well beyond motoring circles, which kept the Xantia in the conversation long after production ended.

Which engines did the Xantia use?

The engine range used PSA's XU petrol and XUD diesel units. Petrol options included the 2.0i 16V in 97 kW (132 hp) and 110 kW (150 hp) forms, the 2.0i Turbo CT at 108 kW (147 hp), and the 3.0i V6 at 140 kW (190 hp), which arrived in 1997. Fewer than 2,600 Activa V6 models were built.

The XUD 1.9 diesel was the best-selling engine in the range. The biggest diesel was the 2.1 Turbo D12, producing 80 kW (109 hp), and in 1998 PSA added the HDi direct-injection turbodiesel in 90 PS (66 kW) and 109 PS versions. The HDi was capable of 190 km/h (118 mph).

UK-market Activa models used a 2.0-litre turbo rated at 150 bhp and 171 lb ft. It was a low-pressure turbo tuned for smooth delivery rather than outright power, which suited the car's relaxed character.

Choosing between petrol and diesel meant weighing running costs against performance. The diesels offered better economy and strong low-speed pull, while the petrol engines, especially the V6, gave the car its quickest acceleration and a smoother feel at speed.

Where else was the Xantia built?

The car was built in Iran by SAIPA in Tehran from 2001 to 2010 in four variants. Every Iranian model used a five-speed manual gearbox in a five-door liftback body, and it was the first Citroen SAIPA had built since the Dyane Jian.

The February 2000 contract was meant to make SAIPA a hub for exports to the Middle East, Central Asia, Russia and Ukraine. The partners expected 9,500 of the 12,000 cars to be sent abroad in 2001, and at least 40% of parts were to be made in Iran.

In China the Xantia was assembled in kit form at Huizhou in Guangdong province from 1996 to 1997. Those cars were badged as XM, under the name Fengshen Xietuolong XM, and the venture was small enough that production numbers stayed very low.

The Iranian and Chinese chapters show how the Xantia travelled beyond Europe. In each case local assembly or licensing gave the car a second life in markets where imported cars faced steep duties, which shaped the way the model was built and sold. Local partners also had to meet domestic rules, which meant some cars differed noticeably from their European originals in trim and equipment.

Taken together, these overseas programmes mark the car as more than a European niche model. They also explain why spare parts were a concern for owners in some countries, since supply lines were long and sometimes unreliable.

What are the Citroen Xantia specifications?

The table covers the main engines and the production figures. Each row names the model or market that the figure applies to, so the Activa and the standard car are not mixed up. Metric figures come first, and imperial values appear in brackets wherever they were published.

Frequently asked questions

How many Activas were built?

Just over 18,000 Activas were built between the spring of 1995 and the autumn of 2001, which made it a relatively small part of the Xantia's total output.

What is the Xantia's SC.CAR system?

SC.CAR is the Activa's active cross-stabiliser. It uses hydraulic cylinders to work against the anti-roll bars, reducing body lean in corners.

Did the Xantia use LHM fluid?

Yes. The Xantia was the last Citroen to use LHM, a mineral green fluid, before later models moved to a different hydraulic fluid.

Which engine sold best?

Buyers chose the XUD 1.9 turbo diesel more often than any other unit, which made it the volume choice of the line-up.
