The Citroen C4 III, specifically the 1.2 PureTech 155 horsepower automatic variant produced between February 2021 and March 2022, represents a key offering within the third generation of Citroen’s popular compact model. Positioned as a mid-range option, this version aimed to balance fuel efficiency with respectable performance, appealing to buyers seeking a comfortable and practical daily driver. The C4 III, built on the CMP (Common Modular Platform) shared with Peugeot and Opel/Vauxhall, marked a departure from the traditional hatchback segment, adopting a more crossover-inspired design.

Powertrain & Engine Architecture
At the heart of this C4 variant lies the 1.2 PureTech engine, specifically the EB2ADTX code. This is a three-cylinder, turbocharged gasoline engine, a member of Citroen’s PureTech family known for its efficiency and responsiveness. The engine utilizes direct fuel injection, optimizing combustion and contributing to improved fuel economy. The turbocharger, coupled with an intercooler, helps to mitigate turbo lag and deliver a broader torque curve. The 155 horsepower output is achieved at 5500 rpm, while peak torque of 240 Nm (177 lb-ft) is available from a low 1750 rpm, providing good everyday drivability. Paired with this engine is an eight-speed automatic transmission (typically an Aisin-sourced unit), designed to provide smooth gear changes and contribute to overall efficiency. This transmission was chosen for its balance of responsiveness and comfort, suiting the C4’s intended role as a comfortable cruiser.
Driving Characteristics
The 1.2 PureTech 155 automatic offers a comfortable and refined driving experience. While not a performance-oriented variant, the engine provides adequate power for most driving situations. Acceleration is respectable, though not particularly brisk, and the eight-speed automatic transmission generally shifts smoothly. The low-end torque, thanks to the turbocharger, makes it easy to navigate city traffic and execute overtaking maneuvers. Compared to the base 1.2 PureTech with around 100 hp, this version offers a noticeable improvement in performance. However, it doesn’t match the responsiveness of higher-powered options, such as the diesel variants. The automatic transmission, while convenient, can sometimes feel hesitant during quick downshifts. The gear ratios are tuned for fuel efficiency, prioritizing comfortable cruising over outright acceleration.
Equipment & Trim Levels
The 1.2 PureTech 155 automatic typically came equipped with a generous level of standard features. Depending on the specific trim level (often denoted as ‘Feel’ or ‘Shine’), standard equipment included air conditioning, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, cruise control, and a suite of safety features such as automatic emergency braking and lane departure warning. Higher trim levels added features like a larger touchscreen, navigation, parking sensors, and upgraded interior upholstery. Interior materials were generally of good quality, with a focus on comfort and practicality. Optional extras included a panoramic sunroof, leather seats, and a premium audio system.
Chassis & Braking
The C4 III utilizes a McPherson strut front suspension and a semi-independent coil spring rear suspension. This setup provides a comfortable ride, absorbing bumps and imperfections in the road effectively. The front brakes are ventilated discs, providing ample stopping power, while the rear brakes are solid discs. ABS (Anti-lock Braking System) is standard, enhancing safety during emergency braking situations. Stabilizer bars are fitted to both the front and rear axles, reducing body roll during cornering. The suspension tuning is geared towards comfort rather than sporty handling, prioritizing a smooth and relaxed driving experience.
Market Reception & Comparison
The Citroen C4 III 1.2 PureTech 155 automatic was generally well-received by automotive critics. It was praised for its comfortable ride, fuel efficiency, and well-equipped interior. However, some reviewers noted that the engine could feel strained under hard acceleration, and the automatic transmission wasn’t always the most responsive. Compared to the 1.5 BlueHDi diesel variants, the PureTech offered a more refined driving experience but lacked the diesel’s superior fuel economy. Against competitors like the Volkswagen Golf, Ford Focus, and Peugeot 308, the C4 III offered a distinctive design and a focus on comfort, setting it apart from the more conventional options.
Legacy
The 1.2 PureTech engine, while generally reliable, has been subject to some reports of timing chain issues in certain model years. Regular maintenance, including oil changes and adherence to Citroen’s recommended service intervals, is crucial for ensuring the longevity of this powertrain. In the used car market, the C4 III 1.2 PureTech 155 automatic represents a good value proposition, offering a comfortable and well-equipped vehicle at a reasonable price. Its blend of practicality, efficiency, and comfort continues to appeal to buyers seeking a versatile and reliable compact car.
