The 1991 Citroën ZX, a compact hatchback, was a significant entry in the French automaker's lineup, marking a departure from the brand's traditionally quirky designs. The ZX was conceived to be a more practical and mainstream offering, aimed at capturing a wider audience. It boasted sharp, contemporary styling with a distinctive wedge-shaped profile, a sleek front end with integrated headlamps, and a large panoramic rear window. The car was available in a variety of body styles, including a three-door hatchback, a five-door hatchback, and a station wagon known as the "Break."

Under the hood, the 1991 ZX offered a range of petrol and diesel engines, catering to different needs and preferences. While some models featured naturally aspirated engines, others were equipped with the innovative "TU" series of gasoline engines equipped with a variable-valve lift system for improved performance and fuel economy. The ZX also introduced Citroen's innovative "Hydractive" suspension system, offering a unique blend of comfort and handling. This sophisticated system employed hydraulically controlled dampers, allowing for variable ride height and a more responsive driving experience. The 1991 Citroen ZX, with its practicality, contemporary design, and advanced engineering, became a popular choice for drivers seeking a blend of French style and efficient performance.
