Citroen GS 1220 (1972-79)
The Citroën GS 1220, introduced in 1972 as an evolution of the original GS (launched in 1970), was designed to fill a critical gap in Citroën’s lineup between the utilitarian 2CV and the luxurious DS. Its concept and intention were rooted in delivering advanced engineering and comfort to the mid-size family car segment, without the cost or complexity of executive models.
🎯 Strategic Purpose
Segment Bridging: Positioned to compete with cars like the Renault 12, Fiat 128, and Ford Escort, the GS 1220 offered a more refined alternative in the compact class.
Democratizing Innovation: Citroën aimed to bring its hallmark technologies—like hydropneumatic suspension and aerodynamic design—to a broader audience.
Performance Upgrade: The 1220 variant addressed criticisms of the original 1015cc GS being underpowered, offering improved drivability and fuel economy.
🧠 Engineering Philosophy
Flat-Four Engine: The air-cooled, 1222cc boxer engine delivered 60 bhp, offering smoother power delivery and higher cruising speeds (up to ~100 mph).
Hydropneumatic Suspension: Borrowed from the DS, this self-leveling system gave the GS unmatched ride comfort and handling for its class.
Aerodynamic Excellence: Its sleek, teardrop shape achieved a low drag coefficient, enhancing fuel efficiency and high-speed stability.
Inboard Disc Brakes: Reduced unsprung weight and improved braking performance—rare in cars of this size and price.
🧪 Design Intent
Maximizing Space: The GS packed generous passenger and luggage room into a compact footprint, aided by its controversial but efficient styling.
Driver-Centric Cabin: Featured Citroën’s signature single-spoke steering wheel, drum-style speedometer, and ergonomic controls.
Adjustable Ride Height: Allowed for kerbside wheel changes and mild off-road capability—practical and quirky in equal measure.
📈 Market and Cultural Impact
European Success: The GS range sold nearly 1.9 million units, with the 1220 becoming the most popular variant.
Car of the Year: The GS won the 1971 European Car of the Year award, validating Citroën’s bold engineering choices.
Cult Following: Though never officially sold in the U.S., the GS 1220 developed a loyal fanbase among enthusiasts who admired its blend of comfort, innovation, and eccentricity.
🧩 Legacy
Precursor to the GSA: The GS 1220 laid the groundwork for the facelifted GSA, which added more refinement and modern features.
Design Influence: Its engineering DNA carried forward into the BX and even influenced later hydropneumatic Citroëns like the XM.
In essence, the GS 1220 was Citroën’s answer to the question: “What if a family car could ride like a limousine, handle like a sports car, and still be affordable?”
