INTRODUCTION

The Citroen CX II 25 GTi Automatic, produced from 1985 to 1989, was a sophisticated evolution of the original CX, known for its distinctive wedge shape and groundbreaking hydropneumatic suspension. The “II” designation indicates the second series of the CX, featuring subtle styling updates and improvements to the interior. The 25 GTi Automatic variant specifically combined the 2.5-liter inline-four engine with a three-speed automatic transmission, aiming to provide a more relaxed driving experience without sacrificing too much of the CX’s inherent character. This model occupied a mid-to-upper position in the CX II lineup, offering a step up in performance and features compared to the base models, but remaining below the more powerful and expensive 25 Turbo variants.

Powertrain & Engine Architecture

At the heart of the CX 25 GTi Automatic lies the M25.659 engine, a 2499cc inline-four cylinder petrol engine. This engine utilized a multi-port fuel injection system, a significant advancement over earlier carbureted Citroen engines, contributing to improved fuel efficiency and smoother power delivery. The engine featured a single overhead camshaft operating two valves per cylinder. The 8.75:1 compression ratio was a compromise between performance and the fuel quality available at the time. The three-speed automatic transmission, while not known for its sportiness, was chosen for its ease of use and suitability for long-distance cruising. It was a traditional torque converter automatic, offering smooth but relatively slow shifts. The transmission’s gear ratios were geared towards comfortable highway driving, prioritizing fuel economy over rapid acceleration.

Driving Characteristics

The driving experience in the CX 25 GTi Automatic is defined by the unique characteristics of its hydropneumatic suspension. This system, a Citroen hallmark, provides an exceptionally smooth and comfortable ride, absorbing bumps and imperfections in the road with remarkable effectiveness. However, the automatic transmission and the 138 horsepower engine meant that acceleration was not particularly brisk. The 0-60 mph time of around 11.1 seconds reflects this. The automatic transmission, while convenient, did detract from the engine’s responsiveness, and downshifts were often slow to occur. Compared to the manual transmission versions of the 25 GTi, the automatic felt noticeably less engaging. The CX’s steering, while precise, could feel somewhat heavy at low speeds, but lightened up at higher speeds, contributing to its stability on the highway.

Equipment & Trim Levels

The 25 GTi Automatic trim level included a number of standard features designed to enhance comfort and convenience. These typically included power steering, central locking, electric windows, and a high-quality stereo system. The interior was typically upholstered in a combination of cloth and velour, with comfortable and supportive seats. Optional extras included leather upholstery, a sunroof, and upgraded audio systems. The dashboard layout was characteristically Citroen, featuring a unique combination of analog gauges and switches. The CX II also benefited from improved interior trim quality compared to earlier CX models.

Chassis & Braking

The CX II utilized a robust chassis with independent suspension on all four wheels, courtesy of the hydropneumatic system. This system allowed for self-leveling, maintaining a consistent ride height regardless of load. The front suspension featured a complex arrangement of spheres and dampers, while the rear suspension employed a similar setup. Braking duties were handled by ventilated discs at the front and solid discs at the rear. An anti-lock braking system (ABS) was included as standard equipment, enhancing safety and control during hard braking. The CX’s relatively low weight, at around 1370 kg (3020 lbs), helped to offset the limitations of its engine power.

Market Reception & Comparison

The CX 25 GTi Automatic received generally positive reviews from automotive critics, who praised its ride comfort, innovative technology, and distinctive styling. However, the automatic transmission was often criticized for its lack of responsiveness and its impact on fuel economy. Compared to the manual transmission versions of the 25 GTi, the automatic offered less driver engagement. The 25 Turbo models, with their turbocharged engines, provided significantly more performance but came at a higher price point. The CX 25 GTi Automatic appealed to buyers who prioritized comfort and convenience over outright performance, and who appreciated the unique character of the Citroen brand.

Legacy

The Citroen CX II 25 GTi Automatic, while not the most sought-after variant of the CX, remains a respected and admired classic car. The hydropneumatic suspension system, while requiring specialized maintenance, is renowned for its exceptional ride quality. The M25.659 engine is generally considered to be a reliable unit, although regular maintenance is essential. Today, the CX 25 GTi Automatic is a relatively rare sight on the road, and well-maintained examples are becoming increasingly collectible. Its unique blend of innovation, comfort, and style continues to appeal to enthusiasts who appreciate Citroen’s engineering ingenuity.
