Robert Opron · 1970
The Citroën GS is a small family car designed by Robert Opron, launched in 1970 after winning Citroën’s 1967 internal Project G competition. It was built as a fastback four-door saloon and five-door estate until 1979. A revised version, the GSA, was produced from late 1979 until 1986 in five-door hatchback or estate body styles. Combined production reached approximately 2.5 million units. It has a front-engine, front-wheel-drive layout and seating for five passengers. Noted for its aerodynamic body shape with a drag coefficient of 0.318, fully independent hydro-pneumatic brakes and self-levelling suspension, and air-cooled flat-four engine, the GS was styled by Robert Opron, with a low nose, a two-box silhouette, semi-enclosed rear wheels and a sharply vertical Kamm-tail. In 1967, having abandoned the ambitious Projet F begun by Bertoni and taken over by Opron, Citroën initiated a competition for a new mid-range model that pitted Opron and the Bureau d'Études against Giorgetto Giugiaro and Italdesign. Both teams submitted designs for front wheel drive three- and five-door cars powered by flat-four engines. Opron's proposal carried the day, and his Project G eventually became the GS released in 1970. Some have claimed that Opron based the GS' shape on the Pininfarina Austin 1800 Aerodinamica Berline of 1967. Others assert that, while it may have been influenced by the Italo-English concept car, Opron's design was an independent work, and point out that Citroën has never acknowledged any link.
