The Citroën CX 2000, produced between 1974 and 1979, represented a significant evolution in Citroën’s engineering prowess. Positioned as an entry-level variant within the broader CX range, the 2000 model offered a blend of comfort, advanced technology, and reasonable performance. It was a key component of the initial CX lineup (Series I), built on the platform designated as the CX I. The CX, as a whole, was intended to replace the venerable Citroën DS, carrying forward the company’s tradition of innovative design and hydropneumatic suspension. The 2000 model, with its 102 horsepower engine, aimed to provide a more accessible price point for buyers intrigued by the CX’s futuristic appeal.

Powertrain & Engine Architecture
The Citroën CX 2000 was powered by the M20.616 engine, a 1985cc inline-four cylinder unit. This engine, while relatively modest in output compared to the later fuel-injected and turbocharged variants, was a robust and reliable design. It featured a single overhead camshaft (SOHC) valvetrain with two valves per cylinder. Fuel delivery was handled by a Solex C32 PHH carburetor, a common setup for European cars of the era. The engine’s 9:1 compression ratio contributed to its reasonable torque output of 152 Nm (112 lb-ft) at 3000 rpm. The engine was transversely mounted, a layout that maximized interior space and contributed to the CX’s front-wheel-drive configuration. The transmission was a four-speed manual gearbox, providing a relatively direct connection between the engine and the wheels.
Driving Characteristics
The CX 2000, with its 102 horsepower and four-speed manual transmission, offered a comfortable but not particularly sporty driving experience. Acceleration to 60 mph took around 12.4 seconds, and top speed was approximately 108 mph. The engine felt somewhat strained at higher speeds, and overtaking required careful planning. The gear ratios were spaced to prioritize fuel economy and smooth cruising rather than outright performance. Compared to the later 2.2-liter and V6-powered CX models, the 2000 felt noticeably slower. However, the CX’s signature hydropneumatic suspension provided an exceptionally smooth and comfortable ride, absorbing bumps and imperfections in the road with remarkable ease. This ride quality was a defining characteristic of the CX and set it apart from many of its competitors.
Equipment & Trim Levels
The CX 2000 was typically equipped with a relatively basic level of trim, reflecting its position as the entry-level model. Standard features included cloth upholstery, a basic dashboard layout, and manual windows. However, even the base CX 2000 benefited from the advanced technology of the hydropneumatic suspension, which automatically adjusted ride height and provided self-leveling capabilities. Optional extras included upgraded upholstery, a sunroof, and a more sophisticated radio. The interior design, while functional, was typically understated and focused on providing a comfortable and practical driving environment.
Chassis & Braking
The CX featured a monocoque chassis construction, providing a strong and rigid platform. The hydropneumatic suspension system, utilizing spheres filled with nitrogen gas and hydraulic fluid, was the cornerstone of the CX’s handling and ride quality. The front suspension utilized independent double wishbones, while the rear suspension employed trailing arms. Braking was provided by ventilated discs at the front and solid discs at the rear, offering adequate stopping power for the car’s weight and performance. The steering was rack and pinion, providing precise and responsive control.
Market Reception & Comparison
The Citroën CX 2000 received mixed reviews upon its launch. Critics praised the car’s innovative suspension and comfortable ride, but some found the engine to be underpowered. Compared to its rivals, such as the Peugeot 504 and the Rover SD1, the CX offered a more futuristic design and a more sophisticated suspension system. However, the Peugeot and Rover offered a wider range of engine options, including more powerful alternatives. The CX 2000’s fuel economy was reasonable for its time, but it was not class-leading. Reliability was generally good, although the complexity of the hydropneumatic suspension system could lead to occasional maintenance issues.
Legacy
The Citroën CX 2000, while not the most powerful or fastest variant of the CX range, played an important role in establishing the model’s reputation for innovation and comfort. The M20.616 engine proved to be a durable and reliable unit, and many examples are still on the road today. In the used car market, the CX 2000 is often considered a more affordable entry point into CX ownership, offering a taste of the model’s unique character without the higher price tag of the more desirable V6 or turbocharged versions. The hydropneumatic suspension remains the defining feature of the CX, and maintaining this system is crucial for preserving the car’s exceptional ride quality. The CX, as a whole, is now regarded as a classic of French automotive design, and the 2000 model represents a significant piece of that legacy.
