The Citroën C5 II, launched in 2008, represented a significant evolution for Citroën’s flagship sedan. The Phase I models, produced from 2008 to 2010, offered a range of engine options, with the 2.0 HDi 163 hp variant with a Diesel Particulate Filter (FAP) being a popular choice, particularly in European markets. This model aimed to balance fuel efficiency, performance, and refinement within the mid-size executive car segment. It was built on the PSA Group’s Platform 4, also known as the 1HX0 platform, shared with the Peugeot 607.

Powertrain & Engine Architecture
The heart of this C5 variant is the DW10CTED4 engine, a 2.0-liter four-cylinder diesel engine. This engine, commonly found in PSA Group vehicles, utilizes a common rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. The RHH engine code specifically denotes a version equipped with a Diesel Particulate Filter (DPF) to reduce particulate matter emissions, meeting Euro 5 standards. A turbocharger with an intercooler is employed to boost power output and improve torque delivery. The engine features a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, enhancing breathing and overall efficiency. The 6-speed manual transmission was the standard offering for this trim, providing a balance between fuel economy and driver control.
Driving Characteristics
The 163 hp 2.0 HDi engine in the C5 II provided a comfortable and refined driving experience. While not overtly sporty, it offered sufficient power for relaxed cruising and overtaking maneuvers. Acceleration from 0-60 mph took approximately 8.6 seconds, and a top speed of 130 mph was achievable. The engine’s 340 Nm (250 lb-ft) of torque, available from 2000 rpm, provided good in-gear acceleration, making it well-suited for long journeys. Compared to the more powerful 2.2 HDi variants, this engine prioritized fuel economy over outright performance. The 6-speed manual transmission allowed for precise gear selection, although the shift quality wasn’t particularly sporty.
Equipment & Trim Levels
The 2.0 HDi 163 hp variant typically sat in the mid-range of the C5 II lineup. Standard equipment included air conditioning, electric front windows, a CD stereo, and ABS brakes. Higher trim levels, such as Exclusive, added features like leather upholstery, automatic climate control, parking sensors, and a more advanced audio system. Optional extras included a panoramic sunroof, satellite navigation, and xenon headlights. Interior upholstery was generally cloth on the base models, with leather available as an upgrade. The dashboard layout was functional and ergonomically designed, prioritizing ease of use.
Chassis & Braking
The C5 II featured a sophisticated suspension system designed for comfort. The front suspension utilized a double wishbone setup, while the rear employed an independent multi-link configuration. This combination provided a smooth and controlled ride, absorbing bumps and imperfections in the road surface effectively. Brakes consisted of ventilated discs at the front and solid discs at the rear, providing adequate stopping power. ABS (Anti-lock Braking System) was standard, enhancing safety during emergency braking situations. The hydraulic power steering offered a light and precise feel.
Market Reception & Comparison
The Citroën C5 II 2.0 HDi 163 hp received generally positive reviews from automotive critics. It was praised for its comfortable ride, fuel efficiency, and spacious interior. However, some critics noted that the engine lacked the punch of its more powerful counterparts. Compared to the 2.2 HDi models, the 2.0 HDi offered better fuel economy but less performance. Against competitors like the Ford Mondeo and Volkswagen Passat, the C5 II distinguished itself with its unique Hydractive suspension (available on some trims) and its focus on comfort. Reliability was generally good, although the DPF could require occasional maintenance.
Legacy
The 2.0 HDi engine proved to be a durable and reliable unit when properly maintained. The C5 II 2.0 HDi 163 hp remains a popular choice in the used car market, particularly for those seeking a comfortable and fuel-efficient long-distance cruiser. The DPF can be a potential source of issues if not properly cared for, requiring periodic regeneration or, in some cases, replacement. However, with regular servicing and attention to maintenance, this variant of the C5 II continues to offer a compelling blend of practicality, comfort, and economy.
