Xantia Activa active anti-roll bars
In 1994, the Activa technology was introduced, which is an extension to the Hydractive II suspension, where two additional spheres and two hydraulic cylinders are used together with computer control to eliminate body roll completely. This technology is more broadly known as active suspension, and the Xantia Activa has exceptional road holding comparable to true sports cars. It employs active anti-roll bars.
In the Swedish magazine Teknikens Värld's moose test the 1999 model of Xantia V6 Activa still holds the record speed through the manoeuvre - faster than the Porsche 996 GT2.
UK 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 Xantia was the last Citroën to use a common hydraulic circuit for suspension, brakes and steering like the pioneering Citroën DS. It was also the last Citroën car that used the green LHM hydraulic fluid. Later cars, such as the C5, used LDS instead.
