The Citroën ZX 1.1i, produced between 1992 and 1994, represented the entry point into the ZX range, Citroën’s replacement for the popular BX. This 3-door hatchback variant, powered by a modest 1.1-liter engine producing 60 horsepower, was aimed at budget-conscious buyers and those seeking economical transportation. It was part of the first phase (N2) of the ZX, characterized by its distinctive styling and innovative suspension technology. The ZX, as a whole, aimed to blend practicality, comfort, and a touch of Citroën’s renowned engineering flair, and the 1.1i model played a crucial role in making that accessible to a wider audience.

Powertrain & Engine Architecture
The heart of the ZX 1.1i was the HDZ (or sometimes ADZ) engine, a member of Citroën and Peugeot’s TU series of inline-four cylinder engines. This 1124cc unit featured a single overhead camshaft (OHC) operating two valves per cylinder. Fuel delivery was handled by a single-point fuel injection system, a relatively basic setup compared to the multi-point injection found in higher-spec ZX models. This system, while cost-effective, contributed to the engine’s modest power output. The engine’s design prioritized fuel efficiency and reliability over outright performance. The 5-speed manual transmission was the only gearbox option available with this engine, chosen for its simplicity and contribution to fuel economy. The engine’s transverse mounting within the front-wheel-drive chassis helped maximize interior space.
Driving Characteristics
The ZX 1.1i offered a predictably unhurried driving experience. With only 60 horsepower on tap, acceleration was leisurely, and overtaking required careful planning. The 5-speed gearbox, while well-matched to the engine, couldn’t fully compensate for the lack of torque. However, the car was perfectly adequate for urban driving and shorter journeys. The relatively light weight of the ZX (around 935 kg) helped to mitigate the engine’s limitations. The steering was light and precise, and the suspension, a hallmark of Citroën design, provided a comfortable ride, even on less-than-perfect road surfaces. Compared to the more powerful 1.6 and 2.0-liter ZX variants, the 1.1i felt significantly slower, but it offered a more forgiving and economical driving experience.
Equipment & Trim Levels
The 1.1i ZX was typically the base model, and as such, came with a fairly basic level of equipment. Standard features included power steering, a basic stereo, and cloth upholstery. The interior was functional and durable, but lacked the refinements found in higher trim levels. Options were limited, but could include central locking, electric front windows, and a sunroof. The dashboard layout was simple and straightforward, prioritizing ease of use over aesthetic flair. The 3-door configuration meant rear seat access was less convenient than in the 5-door model.
Chassis & Braking
The ZX featured an independent McPherson strut front suspension and a unique hydro-pneumatic rear suspension system. This rear suspension, a Citroën signature, provided exceptional ride comfort and self-leveling capabilities. The front brakes were discs, while the rear brakes were drums – a cost-saving measure for the entry-level model. ABS (Anti-lock Braking System) was available as an option, enhancing safety. The chassis was relatively lightweight, contributing to the car’s nimble handling. Stabilizer bars were fitted to both the front and rear axles, helping to reduce body roll during cornering.
Market Reception & Comparison
The ZX 1.1i was generally well-received as an affordable and practical hatchback. Critics praised its comfortable ride and fuel efficiency, but noted its lack of performance. Compared to rivals like the Renault 19 and Peugeot 305, the ZX 1.1i offered a compelling combination of value and comfort. However, the 1.6-liter ZX models offered a significant performance upgrade for a relatively small price increase, making them a popular alternative for those willing to spend a little more. Fuel economy was a strong point for the 1.1i, typically achieving around 45-50 mpg in mixed driving conditions. Reliability was generally good, although the single-point fuel injection system could occasionally require maintenance.
Legacy
The Citroën ZX 1.1i, while not a performance icon, remains a fondly remembered example of affordable French motoring. The HDZ engine proved to be reasonably durable, and many examples are still on the road today. In the used car market, the 1.1i ZX represents a very affordable entry point into classic Citroën ownership. Its simplicity and low running costs make it an attractive option for those seeking a reliable and economical vehicle. While it may not offer the thrills of its more powerful siblings, the ZX 1.1i provides a comfortable and practical driving experience, embodying Citroën’s commitment to innovation and accessibility.
