The Citroen C4 L Sedan, specifically the Phase II model produced from 2016 to 2018, represented Citroen’s entry into the competitive compact sedan market, particularly aimed at regions like China and South America. This variant, equipped with the 1.6 HDi diesel engine producing 114 horsepower, occupied a middle ground in the C4 L Sedan lineup, offering a balance between fuel efficiency and acceptable performance. It was positioned as a more economical alternative to the petrol-powered versions and a slightly less powerful, yet more fuel-conscious, option compared to higher-output diesel trims. The C4 L Sedan itself was a lengthened version of the standard C4, designed to cater to markets where rear passenger space was highly valued.

Powertrain & Engine Architecture
The heart of this C4 L Sedan variant is the 1.6-liter HDi diesel engine, specifically the 9HD DV6C code. This engine belongs to the PSA Group’s DV6 family, known for its relatively compact size and fuel efficiency. It features a common rail direct injection system, delivering fuel at high pressure for optimized combustion. The engine utilizes a single overhead camshaft (SOHC) valvetrain with two valves per cylinder. A turbocharger with an intercooler is employed to boost power output and improve torque across a wider rev range. The 114 horsepower and 270 Nm (199 lb-ft) of torque are respectable figures for a 1.6-liter diesel, providing adequate performance for everyday driving. The engine is transversely mounted in the front of the vehicle. The six-speed manual transmission was the standard offering, chosen for its efficiency and cost-effectiveness.
Driving Characteristics
The 1.6 HDi engine, paired with the six-speed manual gearbox, delivers a driving experience focused on fuel economy rather than outright performance. Acceleration from 0-60 mph takes around 10.8 seconds, which is adequate for typical commuting and highway merging. The engine’s torque peak at 1750 rpm provides good low-end responsiveness, making it easy to navigate city traffic. However, the engine can feel strained at higher speeds or when carrying a full load of passengers and luggage. The gear ratios are well-spaced, allowing the driver to keep the engine within its optimal power band. Compared to the more powerful diesel variants, this 1.6 HDi version offers a smoother, less aggressive driving experience. It also feels lighter and more nimble in corners than the heavier, higher-spec models.
Equipment & Trim Levels
The 1.6 HDi variant of the C4 L Sedan typically came with a reasonable level of standard equipment. This included air conditioning, power windows, power door locks, and a basic audio system with USB connectivity. Safety features such as ABS, electronic brakeforce distribution (EBD), and front airbags were also standard. Higher trim levels offered additional features like alloy wheels, a more advanced infotainment system with a touchscreen display, rear parking sensors, and automatic climate control. Interior upholstery was typically cloth, with options for leather seats on higher trims. The dashboard layout was functional and straightforward, prioritizing ease of use over luxurious aesthetics.
Chassis & Braking
The C4 L Sedan utilizes a McPherson strut suspension setup at the front, providing a comfortable ride and decent handling. The rear suspension is a semi-independent torsion beam arrangement, which is a cost-effective solution that offers a good balance between ride comfort and handling. The front brakes are ventilated discs, providing adequate stopping power, while the rear brakes are solid discs. The electric power steering offers light and precise steering feel. The 215/55 R16 tires provide a good compromise between grip and rolling resistance, contributing to fuel efficiency. The suspension tuning is geared towards comfort, absorbing bumps and imperfections in the road surface effectively.
Market Reception & Comparison
The Citroen C4 L Sedan 1.6 HDi was generally well-received in markets where it was sold, particularly for its fuel efficiency and affordability. Critics praised its comfortable ride and spacious interior. However, some reviewers noted that the engine lacked the punch of the more powerful diesel options. Compared to its competitors, such as the Volkswagen Jetta and the Toyota Corolla, the C4 L Sedan offered a unique blend of French styling and practicality. Its fuel economy was competitive, and its price point made it an attractive option for budget-conscious buyers. The 1.6 HDi engine proved to be reliable, although regular maintenance was essential to ensure optimal performance.
Legacy
The 1.6 HDi engine, in various iterations, has proven to be a durable and reliable powertrain. While not known for blistering performance, it has earned a reputation for longevity and fuel efficiency. In the used car market, the C4 L Sedan 1.6 HDi remains a relatively affordable and practical option. However, potential buyers should be aware of the importance of regular maintenance, particularly regarding the diesel particulate filter (DPF) and the turbocharger. Overall, the C4 L Sedan 1.6 HDi represents a sensible and economical choice for those seeking a comfortable and fuel-efficient compact sedan.
