The Citroën GS and GSA, produced between 1970 and 1986, were compact cars that marked a significant leap forward in the French automaker's design philosophy. The GS, launched in 1970, was a revolutionary car for its time. It boasted a sleek, aerodynamic design with a low drag coefficient, making it one of the most fuel-efficient cars in its class. The GS was also the first car to feature a hydropneumatic suspension system, providing unparalleled comfort and handling. The suspension system, developed by Citroën, allowed for self-leveling and variable ride height, offering both a smooth ride on rough roads and sporty handling on winding roads. Other innovative features included a highly efficient and compact air-cooled flat-four engine, a spacious and modern interior, and a distinctive 'floating' dashboard design. The GS was a critical and commercial success, winning the European Car of the Year award in 1971. The GSA, launched in 1979, was a facelifted and slightly larger version of the GS. The GSA featured a new front end with larger headlights and a more angular grille, along with a revised rear end with a new taillight design. The GSA also received a larger engine option, a 1.2-liter engine that provided more power and torque. Despite the GSA's success as a replacement for the GS, Citroën struggled to compete with other manufacturers offering fuel-efficient designs. The GSA's fuel economy was overshadowed by the rise of new Japanese imports during this period. The GSA continued to be produced until 1986, when it was replaced by the Citroën BX. The Citroën GS and GSA remain classic examples of French automotive innovation and style, and their unique design and technological advancements paved the way for future Citroën models.
