The GS filled the gap in Citroën's range, between the2CVandAmieconomy carsand the luxuriousDSexecutive sedan. The DS had moved significantly upmarket from its predecessor theCitroën Traction Avant, and beyond the finances of most French motorists.[6]Leaving this market gap open for fifteen years allowed other manufacturers entry into the most profitable, high volume market segment in France. This combined with the development costs and new factory for the DS-replacingCitroën CX, the 1974oil crisis, and an abortedWankel rotary engine, led Citroën to declare bankruptcy in 1974.
The GS met with instant market acceptance and was the largest selling Citroën model for many years. 1,896,742 GS models and 576,757 GSA models were produced in total.
Unlike the 2CV, DS and SM, the GS was never officially imported to the USA
