The Citroen CX II Break 25 TRi Automatic, produced between 1985 and 1990, represents a luxurious and technologically advanced iteration of Citroen’s iconic CX estate car. Positioned as a mid-to-high range trim level within the CX II Break lineup, it offered a blend of performance, comfort, and practicality aimed at discerning buyers. The CX, as a whole, was Citroen’s flagship saloon and estate, succeeding the DS and continuing the company’s tradition of innovative hydropneumatic suspension. The “Break” designation signified the estate (station wagon) body style, offering increased cargo capacity compared to the saloon. This particular 25 TRi variant, equipped with a 2.5-liter engine and a three-speed automatic transmission, was designed to provide effortless cruising and a refined driving experience.

Powertrain & Engine Architecture

The heart of the CX 25 TRi Automatic is the M25.659 engine, a 2.5-liter inline-four cylinder petrol engine. This engine featured a cast iron block and an aluminum cylinder head, employing a single overhead camshaft (SOHC) design with two valves per cylinder. Fuel delivery was managed by a Bosch multi-port fuel injection system, contributing to improved efficiency and smoother operation compared to earlier carbureted Citroen engines. The engine produced 138 horsepower at 5000 rpm and 211 Nm (155.63 lb-ft) of torque at 4000 rpm. The engine’s transverse mounting saved space in the engine bay and contributed to the car’s front-wheel-drive configuration. Paired with the engine was a three-speed automatic transmission, designed for comfortable and relaxed driving. While not offering the performance of a manual gearbox, it suited the car’s grand touring character.

Driving Characteristics

The CX 25 TRi Automatic prioritized comfort and ease of driving over outright performance. The three-speed automatic transmission, while smooth, resulted in a slightly less responsive feel compared to the five-speed manual versions. Acceleration from 0 to 60 mph took approximately 9.9 seconds, and the top speed was around 118.68 mph. The automatic gearbox’s gear ratios were optimized for cruising, providing relaxed highway performance. However, it could feel somewhat sluggish during quick overtaking maneuvers. The CX’s signature hydropneumatic suspension, however, provided an exceptionally smooth and comfortable ride, absorbing bumps and imperfections in the road with remarkable effectiveness. This suspension system also allowed for self-leveling, maintaining a consistent ride height regardless of load.

Equipment & Trim Levels

The 25 TRi Automatic trim level was well-equipped for its time. Standard features included power steering, central locking, electric windows, and a high-quality stereo system. The interior typically featured comfortable cloth upholstery, although leather was available as an optional extra. The dashboard layout was characteristically Citroen, with a unique combination of analog gauges and switches. Optional extras included air conditioning, a sunroof, and upgraded sound systems. The “TRi” designation indicated a higher level of trim and equipment compared to the base CX 25 models.

Chassis & Braking

The CX II Break featured a robust chassis designed to handle the weight of the estate body and the hydropneumatic suspension system. The front suspension utilized Citroen’s innovative hydropneumatic technology, providing a remarkably smooth and controlled ride. The rear suspension also employed a hydropneumatic system, further enhancing ride comfort. Braking duties were handled by ventilated discs at the front and solid discs at the rear, providing adequate stopping power for the car’s weight and performance. Hydraulic assistance was standard for the steering, making maneuvering at low speeds easier.

Market Reception & Comparison

The Citroen CX II Break 25 TRi Automatic was generally well-received by automotive critics, who praised its comfortable ride, spacious interior, and innovative technology. However, some critics noted the automatic transmission’s lack of responsiveness compared to the manual gearbox. Compared to other estate cars of the time, the CX offered a unique blend of luxury, practicality, and advanced engineering. The 25 TRi Automatic was positioned above the base CX 25 models in terms of price and equipment, but below the more powerful and expensive CX 25 GTI. Fuel economy, at around 20.5 US mpg combined, was typical for a car of its size and engine displacement in the late 1980s.

Legacy

The Citroen CX, while not a massive sales success, remains a beloved classic among Citroen enthusiasts. The 25 TRi Automatic powertrain, while not the most powerful in the CX lineup, is known for its reliability and relative simplicity. Today, well-maintained examples of the CX II Break 25 TRi Automatic are sought after by collectors and enthusiasts who appreciate its unique character and advanced technology. Parts availability can be a challenge, but a dedicated network of Citroen specialists and suppliers exists to support owners. The CX’s hydropneumatic suspension, while requiring specialized maintenance, continues to provide a ride quality that few modern cars can match.
