Citroën GS 1015 Club
The first Citroën GS brought the company's self-levelling hydraulic suspension, four disc brakes and an air-cooled flat-four into a compact five-seat family car. Its smooth fastback outline hid a conventional separate boot rather than a hatchback.

A matching completed auction sale has not been verified for this exact year, body, trim, engine, transmission and market.

More than a set of wheels.
Citroën presented the GS at the 1970 Paris Motor Show and built it at Rennes-la-Janais. It became European Car of the Year for 1971. Citroën's retrospective records about 2.5 million GS and GSA sales from 1970 to 1987, showing how an unusual machine with hydraulic suspension and a rolling-drum speed display became a mainstream family car.
Look a little closer.
Instead of an ordinary needle, the GS showed road speed on a rotating drum viewed through a magnifying window.

Comfort powered by pressure
The GS's hydropneumatic suspension let each wheel move while pressurized fluid and gas spheres carried the car's weight. The system could level the body as passengers or luggage were added and offered adjustable ground clearance. Citroën paired it with four disc brakes, unusual equipment for a modest family car in 1970.

The roof and tail slope smoothly to reduce drag, yet the early GS uses a separate boot lid. Citroën balanced that aerodynamic body with seating for five and a 465-litre boot, showing that the flowing shape was meant to work as a practical family saloon rather than only as a styling exercise.
