The Citroën C5 I (Phase I), produced between 2000 and 2004, represented a significant step forward for the French automaker, aiming to compete directly with established European executive cars like the Ford Mondeo and Volkswagen Passat. The 2.2 HDi 136 Automatic variant, equipped with a four-speed automatic transmission and a Diesel Particulate Filter (FAP), occupied a mid-range position within the C5 lineup, offering a balance of performance, comfort, and fuel efficiency. This model was primarily marketed in Europe, where diesel engines and automatic transmissions were gaining popularity, particularly for long-distance driving.

Powertrain & Engine Architecture
The heart of the C5 2.2 HDi Automatic is the DW12TED4 engine, a 2.2-liter inline-four diesel engine. This engine, developed jointly by PSA (Peugeot Citroën) and Renault, utilizes a common rail direct injection system, delivering fuel at extremely high pressure for improved combustion efficiency and reduced emissions. The turbocharger, a key component, provides increased air intake, boosting power output. The engine features a double overhead camshaft (DOHC) valvetrain, optimizing valve timing for enhanced performance. The FAP (Filtre à Particules) or Diesel Particulate Filter, was a crucial addition to meet increasingly stringent European emission standards, trapping soot particles from the exhaust. The four-speed automatic transmission, while providing convenience, was a somewhat dated design by the early 2000s, impacting both acceleration and fuel economy compared to the available manual gearbox.
Driving Characteristics
The 2.2 HDi Automatic offered a comfortable and relaxed driving experience. With 136 horsepower and 320 Nm (236 lb-ft) of torque, it provided adequate performance for everyday driving and highway cruising. However, the automatic transmission’s relatively long gear ratios meant that acceleration wasn’t particularly brisk, taking around 12.3 seconds to reach 62 mph. Compared to the 1.8-liter petrol versions, the HDi offered significantly more torque, making it easier to overtake and carry a full load. The manual transmission variants of the 2.2 HDi felt more responsive and offered better fuel economy. The automatic, while smooth, lacked the engagement and control preferred by driving enthusiasts.
Equipment & Trim Levels
The 2.2 HDi Automatic typically came equipped with features such as air conditioning, power windows, central locking, and an RDS radio. Higher trim levels, such as Exclusive, added options like leather upholstery, automatic headlights and wipers, a sunroof, and upgraded audio systems. Safety features included ABS brakes, front airbags, and, depending on the year, side airbags. The interior design was functional and comfortable, though not particularly luxurious. The dashboard layout was typical of Citroën at the time, with a focus on ergonomics and ease of use.
Chassis & Braking
The C5 I featured a McPherson strut front suspension and a semi-independent torsion beam rear suspension. This setup prioritized ride comfort, absorbing bumps and imperfections in the road effectively. The front brakes were ventilated discs, providing good stopping power, while the rear brakes were solid discs. The hydraulic power steering offered a light and precise feel. The C5’s suspension was tuned for comfort rather than sporty handling, resulting in a slightly softer and more forgiving ride than some of its competitors.
Market Reception & Comparison
The Citroën C5 I 2.2 HDi Automatic was generally well-received by automotive critics. It was praised for its comfortable ride, fuel efficiency, and refined engine. However, the four-speed automatic transmission was often criticized for its lack of responsiveness and contribution to slightly higher fuel consumption compared to the manual version. Compared to the petrol-powered C5 variants, the HDi offered superior fuel economy and torque, making it a popular choice for drivers covering long distances. The Volkswagen Passat and Ford Mondeo were often seen as more dynamically engaging alternatives, but the C5 offered a unique blend of French comfort and practicality.
Legacy
The DW12TED4 engine proved to be a robust and reliable unit, capable of high mileage with proper maintenance. The four-speed automatic transmission, however, is a potential weak point, and examples with high mileage may exhibit signs of wear. Today, the C5 I 2.2 HDi Automatic represents an affordable and comfortable used car option. While not a performance car, it offers a practical and economical solution for those seeking a spacious and well-equipped family sedan. Parts availability is generally good, and the C5’s relatively simple construction makes it a reasonably straightforward vehicle to maintain for those with some mechanical aptitude.
