Combined production reached approximately 2. Noted for its aerodynamic body shape with a drag coefficient of 0. When the GS was named the European Car of the Year for , the design was noted as technologically advanced, [ 5 ] [ 6 ] with class leading comfort, safety and aerodynamics.
After the project was cancelled, these orphaned cars were sold, mostly to employees of the dealerships. Setright noted that with the arrival of the GS, the automotive industry would have to re-evaluate its offerings, seeing what he described as a "lemming-like rush towards a sea of mediocrityβ¦" [ 10 ]. Development continued with ideas like a Wankel engine and hydropneumatic suspension suggested as possibilities, with a new, modern body to match.
Another iteration was the "C60," which resembled an Ami 6 with a long, smooth nose. In , development had moved to "Project F", which was close to being production-ready.
Many of the mechanical components continued to "Project G", which became the GS. The body style was as a Berline a four-door saloon with three side windows , in a fastback style with a sharp Kammback. The aerodynamics gave the best drag coefficient of any vehicle at the time. The GS's aerodynamics enabled the car to make the best of the available power, but when introduced, the car was considered underpowered.
From September , the GS was also available [ 18 ] as a four door station wagon estate and a similar two-door "service" van. Both the early GS until and the GSA were fitted with a rotating drum speedometer similar in construction to bathroom scales , rather than the dials found in a conventional instrument panel.
