The Citroën C5 I (Phase II), specifically the 3.0i V6 24V automatic variant produced between 2004 and 2008, represented a significant offering in the mid-size executive car segment. Positioned as a premium trim level within the C5 I range, it aimed to provide a blend of comfort, performance, and sophisticated technology. This iteration of the C5, built on the 1HX0 platform, was Citroën’s flagship, intended to compete with vehicles like the Peugeot 607, Renault Safrane, and Ford Mondeo in European markets. The Phase II update brought styling revisions and refinements to the original C5 I, enhancing its appeal and addressing some initial criticisms.

Powertrain & Engine Architecture
The heart of this C5 variant is the ES9A engine code, a 2.9-liter (2946 cc) naturally aspirated V6 engine. This engine, part of Citroën’s ES series, features a 60-degree V-angle and utilizes a cast iron block with aluminum cylinder heads. It employs multi-port fuel injection and four valves per cylinder (24V) to achieve its 207 horsepower output at 6000 rpm and 285 Nm (210 lb-ft) of torque at 3750 rpm. The engine’s design prioritized smooth operation and refinement over outright performance. The automatic transmission is a six-speed unit, designed to provide comfortable shifting and efficient power delivery. While not a particularly advanced transmission by modern standards, it was well-suited to the engine’s characteristics and the C5’s focus on comfort.
Driving Characteristics
The 3.0i V6 automatic C5 offered a relaxed and refined driving experience. Acceleration to 60 mph took approximately 8.2-8.6 seconds, making it reasonably quick for its time, but not a performance leader. The automatic transmission, while smooth, could feel somewhat hesitant during quick overtaking maneuvers. Compared to the manual transmission versions of the same engine, the automatic sacrificed some responsiveness. The gear ratios were tuned for comfortable cruising rather than aggressive acceleration. The V6 engine provided ample torque for everyday driving, making it easy to maintain highway speeds and navigate city traffic. The C5’s hydropneumatic suspension (a Citroën hallmark) contributed significantly to ride comfort, absorbing bumps and imperfections in the road with ease.
Equipment & Trim Levels
The 3.0i V6 automatic typically came with a generous level of standard equipment. This included features like automatic climate control, power windows and mirrors, a CD stereo system, and alloy wheels. Higher trim levels offered options such as leather upholstery, a sunroof, and parking sensors. Interior materials were generally of good quality, reflecting the C5’s positioning as a premium vehicle. The dashboard layout was functional and ergonomically designed, although some critics found it somewhat dated compared to competitors. Safety features included ABS brakes, front airbags, and side airbags.
Chassis & Braking
The C5 I featured an independent front suspension with McPherson struts and a semi-independent rear suspension with coil springs. This setup provided a good balance between ride comfort and handling. The front brakes were ventilated discs, while the rear brakes were solid discs. ABS (Anti-lock Braking System) was standard. The C5’s hydropneumatic suspension system allowed for adjustable ride height and self-leveling, further enhancing ride comfort and stability. The steering was power-assisted and provided a reasonable level of feedback.
Market Reception & Comparison
The 3.0i V6 automatic C5 was generally well-received by automotive critics. It was praised for its comfortable ride, refined engine, and spacious interior. However, some critics noted that the automatic transmission could be slow to respond and that the fuel economy was relatively poor compared to smaller-engined versions. Compared to the 2.0L petrol and 2.2L HDi diesel variants, the V6 offered significantly more power and refinement but at the cost of increased fuel consumption and a higher purchase price. The HDi diesel models were particularly popular in Europe due to their fuel efficiency and low running costs.
Legacy
The ES9A V6 engine, while not known for being particularly groundbreaking, proved to be relatively reliable when properly maintained. Common issues included oil leaks and occasional problems with the ignition system. The automatic transmission, if serviced regularly, generally held up well over time. Today, the 3.0i V6 C5 I represents an affordable entry point into the world of French executive cars. It appeals to enthusiasts who appreciate its comfortable ride, distinctive styling, and unique hydropneumatic suspension. However, potential buyers should be aware of the potential for higher maintenance costs compared to more modern vehicles, particularly regarding the suspension system.
