1976-1980 Citroen CX I Break Super 2400 (116 Hp)

The Citroën CX I Break Super 2400, produced between 1976 and 1980, represents a distinctive iteration of Citroën’s innovative CX series. This variant, a station wagon (estate) body style, was positioned as a practical yet sophisticated offering within the CX lineup. It served as a family-oriented alternative to the fastback saloon, capitalizing on the growing demand for versatile vehicles in the European market. The CX I Break Super 2400 was notable for retaining the CX’s advanced hydropneumatic suspension, offering a uniquely comfortable ride, while providing significantly increased cargo capacity compared to its fastback sibling. It was a key model in establishing the CX as a modern, technologically advanced vehicle for the discerning buyer.

Technical Specifications

Powertrain & Engine Architecture

The Citroën CX I Break Super 2400 was powered by the M23.623 engine, a 2.4-liter inline-four cylinder petrol engine. This engine, a mainstay of Citroën and Peugeot vehicles of the era, featured a cast iron block and an aluminum cylinder head. It utilized a single overhead camshaft (SOHC) valvetrain with two valves per cylinder. Fuel delivery was managed by a Solex C35 PHH carburetor, a common setup for European vehicles of the time. The engine’s 8.75:1 compression ratio was a compromise between performance and the fuel quality available in various European markets. The engine was transversely mounted, contributing to the CX’s compact engine bay and maximizing interior space. The Super 2400 was equipped with a four-speed manual transmission, delivering power to the front wheels. This configuration was chosen for its balance of cost-effectiveness and drivability.

Driving Characteristics

The CX I Break Super 2400 offered a unique driving experience largely defined by its hydropneumatic suspension. This system, a Citroën hallmark, provided an exceptionally smooth and comfortable ride, absorbing road imperfections with remarkable efficiency. However, the 116 horsepower output and the four-speed manual transmission meant that performance was adequate rather than exhilarating. Acceleration to 60 mph took around 11.8 seconds, and top speed was approximately 108 mph. Compared to the more powerful CX 2500 GTI, the Super 2400 felt noticeably slower, particularly during overtaking maneuvers. The gear ratios were optimized for fuel economy and relaxed cruising, rather than sporty driving. The front-wheel drive configuration provided predictable handling, but lacked the dynamic agility of rear-wheel drive alternatives.

Equipment & Trim Levels

The Super 2400 trim level represented a mid-range offering within the CX I Break lineup. Standard equipment included comfortable cloth upholstery, a basic radio, and power-assisted steering. The interior was characterized by its functional design and emphasis on practicality. Optional extras included a sunroof, upgraded audio systems, and more luxurious upholstery materials. The dashboard layout was typical of Citroën designs of the period, featuring a combination of analog gauges and toggle switches. The CX I Break’s spacious interior and large cargo area were key selling points, making it a popular choice for families and those requiring a versatile vehicle.

Chassis & Braking

The CX I Break featured a monocoque chassis construction, providing a good balance of strength and weight. The hydropneumatic suspension system, utilizing self-leveling spheres and hydraulic dampers, was a defining feature of the chassis. The front suspension employed independent double wishbones, while the rear suspension utilized a trailing arm design. Braking was provided by ventilated disc brakes on all four wheels, offering good stopping power for the vehicle’s weight. The steering system was a rack and pinion setup with power assistance, providing light and precise steering feel. The 5.5J x 14 inch wheels were fitted with relatively narrow tires, contributing to the CX’s comfortable ride but limiting grip in demanding driving situations.

Market Reception & Comparison

The Citroën CX I Break Super 2400 was generally well-received by automotive critics, who praised its comfortable ride, spacious interior, and innovative technology. However, some critics noted the engine’s lack of outright power and the relatively high cost of maintenance associated with the hydropneumatic suspension. Compared to other station wagons of the era, such as the Volvo 245 or the Ford Estate, the CX I Break offered a more sophisticated and technologically advanced package, but at a higher price point. Fuel economy was reasonable for the time, but not exceptional. Reliability was generally good, although the hydropneumatic system required periodic maintenance to prevent leaks and ensure optimal performance.

Legacy

The Citroën CX I Break Super 2400 remains a fondly remembered vehicle among enthusiasts. Its innovative hydropneumatic suspension and distinctive styling have cemented its place in automotive history. While the hydropneumatic system can be complex and expensive to maintain, it continues to provide a uniquely comfortable ride for those willing to invest in its upkeep. Today, the CX I Break Super 2400 is a relatively rare sight on the road, and well-maintained examples are increasingly sought after by collectors. The M23 engine, while not known for its blistering performance, is generally considered to be a durable and reliable unit when properly maintained. The CX I Break Super 2400 stands as a testament to Citroën’s engineering ingenuity and its commitment to providing a unique and comfortable driving experience.
