Citroen CX GTi Turbo 2

The Citroën CX was the spiritual successor to the revolutionary DS, and it inherited that car's hydropneumatic self-leveling suspension, high-pressure hydraulic braking, and otherworldly ride quality. Designed by Robert Opron (who also penned the SM), the CX featured one of the most aerodynamic body shapes of its era — its Cx (drag coefficient) of 0.375 inspired the car's name. The GTi Turbo 2 was the ultimate expression of the CX, pairing a turbocharged 2.5-liter engine with the sophisticated hydropneumatic chassis. The result was a car that could cruise at 220 km/h in incredible comfort, the magic carpet ride of the hydropneumatic suspension smoothing out road imperfections that would unsettle lesser cars. The power-assisted hydraulic steering (DIRAVI) provided speed-sensitive assistance and self-centering action that was unique to Citroën. While competitors relied on conventional springs and dampers, the CX Turbo 2 floated over road surfaces on a cushion of pressurized fluid, maintaining a perfectly level attitude regardless of load. The CX won European Car of the Year in 1975 and remained in production for 17 years, earning devoted fans among those who appreciated true automotive engineering innovation.

The hydropneumatic system is the CX's defining feature and its maintenance Achilles heel — find a Citroën specialist who truly understands these systems. Suspension spheres need regular replacement. Check for rust in sills, rear wheel arches, and boot floor. The turbo engine is robust if maintained. DIRAVI steering box leaks are common. Single-spoke steering wheel is iconic.

Over 1.17 million CX models were produced over 17 years. The GTi Turbo 2 was the range-topping performance variant. The CX was the last Citroën to be designed independently before PSA influence.
