INTRODUCTION
The Citroen C4 II Phase II, launched in 2015, represented a mid-life update to the second-generation C4 hatchback. This refresh brought styling tweaks, updated technology, and revised engine options, including the 2.0 BlueHDi diesel engine producing 150 horsepower. The C4 II aimed to compete in the crowded European C-segment, facing rivals like the Volkswagen Golf, Ford Focus, and Peugeot 308. The 2.0 BlueHDi 150 was positioned as a strong contender for buyers seeking a balance between performance, fuel economy, and refinement. It was a key model in Citroen’s lineup, embodying the brand’s focus on comfort and practicality.
Powertrain & Engine Architecture
The heart of this C4 variant is the DW10FD engine, a 2.0-liter four-cylinder diesel engine. This engine, often referred to by its PSA engine code AHR, is a common rail direct injection (CRDI) unit. The BlueHDi designation signifies the inclusion of Selective Catalytic Reduction (SCR) technology, utilizing AdBlue (Diesel Exhaust Fluid) to reduce nitrogen oxide (NOx) emissions, ensuring compliance with stringent Euro 6 emission standards. The engine features a turbocharger with an intercooler, boosting power and torque. The fuel injection system utilizes piezoelectric injectors for precise fuel delivery and optimized combustion. The engine’s valvetrain consists of four valves per cylinder, contributing to its efficiency and power output. The 6-speed manual transmission was the standard offering, providing a good balance between fuel economy and driver engagement. The transmission’s gear ratios were tuned to maximize the engine’s torque, providing strong acceleration in everyday driving situations.
Driving Characteristics
The 2.0 BlueHDi 150 hp C4 offers a comfortable and refined driving experience. The engine delivers a substantial 370 Nm (272.9 lb-ft) of torque at 2000 rpm, providing strong pulling power from low engine speeds. This makes it well-suited for overtaking and navigating hilly terrain. While not a sports car, the C4 II 2.0 BlueHDi achieves a 0-62 mph (0-100 km/h) time of around 8.8 seconds. The 6-speed manual transmission allows for precise gear changes, and the gear ratios are well-matched to the engine’s characteristics. Compared to the lower-powered diesel variants, the 150 hp version offers noticeably more performance, particularly when fully loaded or on the highway. Compared to the petrol engines, the diesel provides superior fuel economy and torque, albeit with slightly more engine noise and vibration.
Equipment & Trim Levels
The 2.0 BlueHDi 150 typically came equipped with a generous level of standard features. These included air conditioning, electric front windows, a touchscreen infotainment system with Bluetooth connectivity, and alloy wheels. Higher trim levels added features such as automatic climate control, rear parking sensors, a navigation system, and leather upholstery. Interior upholstery was typically cloth, with options for partial leather or full leather available. The dashboard layout was functional and user-friendly, with a focus on ergonomics. Optional extras included a panoramic sunroof, xenon headlights, and a premium audio system.
Chassis & Braking
The C4 II utilizes a McPherson strut front suspension and a semi-independent torsion beam rear suspension. This setup provides a good balance between ride comfort and handling. The front suspension incorporates a stabilizer bar to reduce body roll during cornering. Braking duties are handled by ventilated discs at the front and solid discs at the rear. Anti-lock Braking System (ABS) with Electronic Brakeforce Distribution (EBD) is standard. The steering is a power-assisted rack and pinion system, providing precise and responsive steering feel. The C4 II’s chassis was designed to prioritize comfort, resulting in a relatively soft ride quality.
Market Reception & Comparison
The Citroen C4 II 2.0 BlueHDi 150 received generally positive reviews from automotive critics. It was praised for its fuel efficiency, comfortable ride, and refined engine. Critics noted that the engine provided ample power for everyday driving, and the 6-speed manual transmission was smooth and precise. Compared to the 1.6 BlueHDi variants, the 2.0-liter engine offered a noticeable performance improvement. However, some critics found the interior styling to be somewhat bland compared to rivals like the Volkswagen Golf. Fuel economy figures consistently hovered around 3.8 l/100 km (61.9 US mpg), making it a very economical option for long-distance driving. Reliability reports suggest that the DW10FD engine is generally robust, although regular maintenance is essential.
Legacy
The Citroen C4 II 2.0 BlueHDi 150 remains a popular choice in the used car market. Its combination of fuel efficiency, practicality, and comfort makes it an appealing option for buyers seeking a reliable and economical family car. The DW10FD engine has proven to be durable, and parts availability is generally good. However, potential buyers should be aware of the need for regular maintenance, including AdBlue refills and diesel particulate filter (DPF) servicing. The C4 II represents a solid offering from Citroen, showcasing the brand’s commitment to comfort and innovation in the compact car segment.
