The Citroën XM, produced from 1989 to 2000, stands as a testament to French automotive innovation, serving as the brand's flagship executive car. This model was engineered to compete with established luxury sedans, offering a unique blend of advanced technology and distinctive styling. Notable features include its sophisticated Hydropneumatic suspension system, often referred to as Hydractive, which provided an exceptionally comfortable ride, and its highly aerodynamic design. The XM was available with a range of engine options, including inline-four petrol and diesel units, as well as a more powerful V6 PRV engine, catering to diverse performance preferences. Its production, primarily in France, resulted in approximately 198,952 units, cementing its place as a significant, albeit niche, offering in the automotive landscape.
