The Citroen CX I Break 2200 D, produced between 1976 and 1978, represents a unique offering within the broader CX range. As a diesel-powered station wagon (estate) variant, it catered to a specific segment of the European market seeking practicality and fuel economy. The CX, succeeding the iconic DS, continued Citroen’s tradition of innovative engineering and distinctive styling. The “Break” designation signified the estate body style, offering increased cargo capacity compared to the sedan. This 2200 D model, equipped with a naturally aspirated 2.2-liter diesel engine producing 66 horsepower, occupied the lower end of the CX Break lineup, prioritizing affordability and efficiency over outright performance.

Powertrain & Engine Architecture
The heart of the CX I Break 2200 D was the M22.621 engine, a 2.2-liter inline-four diesel. This engine utilized precombustion chamber injection, a system common in European diesels of the era. This system involved injecting fuel into a small precombustion chamber within the cylinder head, where it ignited and then ignited the main charge in the cylinder. This design aided in smoother combustion and reduced engine noise compared to direct injection systems. The engine produced 66 horsepower at 4500 rpm and 126 Nm (93 lb-ft) of torque at 2750 rpm. The engine’s relatively low compression ratio of 22.25:1 was typical for diesel engines of the time. The engine was transversely mounted, a layout that contributed to the CX’s compact engine bay and improved packaging. The 2200 D was equipped with a four-speed manual transmission, chosen for its simplicity and durability.
Driving Characteristics
The CX I Break 2200 D offered a distinctly different driving experience compared to its gasoline-powered siblings. The lower horsepower output resulted in significantly slower acceleration – approximately 22.8 seconds to 62 mph. However, the diesel engine’s high torque output at low engine speeds provided reasonable drivability in everyday conditions. The four-speed manual transmission, while not offering the sporty feel of a five-speed, was well-suited to the engine’s characteristics. The CX’s renowned hydropneumatic suspension, a Citroen hallmark, provided an exceptionally comfortable ride, even with the added weight of the diesel engine and estate body. Compared to the more powerful gasoline versions, the 2200 D prioritized fuel economy and relaxed cruising over spirited performance.
Equipment & Trim Levels
The CX I Break 2200 D was generally equipped with a modest level of standard features. Interior upholstery was typically cloth, and the dashboard featured a functional, if somewhat austere, design. Standard equipment included power-assisted steering, ventilated disc brakes on all wheels, and the aforementioned hydropneumatic suspension. Optional extras included a sunroof, upgraded audio systems, and more luxurious interior trim options. The 2200 D served as the entry point to the CX Break range, with higher trim levels offering more comfort and convenience features.
Chassis & Braking
The CX I Break utilized a robust chassis designed to accommodate the hydropneumatic suspension system. The suspension, comprised of self-leveling spheres and hydraulic cylinders, provided a remarkably smooth and controlled ride. The front suspension was independent, while the rear suspension employed a trailing arm design. Braking was handled by ventilated discs on all four wheels, providing adequate stopping power for the vehicle’s weight and performance. The steering system was a rack and pinion setup with power assistance, offering precise and responsive handling. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The Citroen CX I Break 2200 D was primarily targeted at buyers seeking a practical and fuel-efficient station wagon. Critics generally praised the CX’s ride comfort and innovative technology, but noted the 2200 D’s relatively slow performance. Compared to the gasoline-powered CX models, the diesel offered significantly better fuel economy, making it an attractive option for high-mileage drivers. However, the diesel engine was also noisier and produced more vibrations than its gasoline counterparts. Against competitors like the Volvo 245 and Peugeot 504 Break, the CX offered a unique blend of comfort, technology, and practicality.
Legacy
The Citroen CX I Break 2200 D, while not the most powerful or fastest variant of the CX, remains a significant example of Citroen’s engineering prowess. The M22.621 diesel 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 I Break 2200 D is appreciated by enthusiasts for its unique character and comfortable ride. While maintenance can be complex due to the hydropneumatic suspension, the CX remains a distinctive and rewarding classic car for those willing to invest the time and effort.
