2008-2009 Citroen C5 II (Phase I ) 1.6 HDi (109 Hp) Airdream

The Citroën C5 II, specifically the 1.6 HDi 109 Airdream variant produced between 2008 and 2009, represented an entry point into the second generation of Citroën’s large family car. Positioned within the broader C5 II (Phase I) range – which spanned from 2004 to 2010 and utilized the PSA Group’s Platform 4 – this model aimed to deliver fuel efficiency and reasonable performance for everyday driving. The “Airdream” designation denoted Citroën’s focus on aerodynamic efficiency and reduced emissions. This version was primarily sold in Europe, catering to buyers seeking a comfortable and economical sedan or station wagon (estate) option.

Technical Specifications

Powertrain & Engine Architecture

The heart of this C5 variant is the 9HZ variant of the DV6TED4 engine, a 1.6-liter inline-four diesel. This engine is a common sight in PSA Group vehicles of the era. It features a turbocharger with an intercooler to boost power and efficiency. The DV6 engine utilizes a common rail direct injection system, delivering fuel directly into the cylinders at extremely high pressure for optimized combustion. The engine employs a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, enhancing breathing and contributing to its power output. The 109 horsepower peak is achieved at 4000 rpm, while the 240 Nm (177 lb-ft) of torque is readily available from 1750 rpm, prioritizing low-end responsiveness. The engine’s relatively high compression ratio of 17.6:1 is typical for diesel engines, aiding in thermal efficiency. The engine was paired with a five-speed manual transmission, chosen for its simplicity and cost-effectiveness. While an automatic transmission was offered on other C5 II models, it wasn’t available with this specific 1.6 HDi engine.

Driving Characteristics

The 1.6 HDi 109 hp engine, coupled with the five-speed manual gearbox, provided adequate, but not exhilarating, performance. Acceleration was modest, with a focus on fuel economy rather than outright speed. The readily available torque made it suitable for everyday driving and overtaking on highways, but it lacked the punch of the higher-powered 2.0 HDi or petrol variants. The gear ratios were tuned for efficiency, with a relatively long fifth gear to reduce engine speed at cruising speeds. Compared to the more powerful C5 models, this variant felt less refined and required more gear changes to maintain momentum, especially when fully loaded or tackling inclines. The manual transmission offered a more engaging driving experience than the automatic options available on other C5 trims.

Equipment & Trim Levels

The 1.6 HDi 109 Airdream typically represented an entry-level or mid-range trim within the C5 II lineup. Standard equipment generally included air conditioning, power windows, central locking, and an audio system. Safety features such as ABS, front airbags, and seatbelt pretensioners were also standard. Higher trim levels added features like alloy wheels, automatic headlights and wipers, a multi-function steering wheel, and upgraded interior trim. Interior upholstery was typically cloth, with options for partial leather available. The dashboard layout was functional and ergonomically designed, prioritizing ease of use. Optional extras included a navigation system, parking sensors, and a panoramic sunroof.

Chassis & Braking

The C5 II featured a comfortable and refined chassis. The front suspension utilized a double wishbone setup, while the rear employed an independent multi-link suspension, providing a good balance between ride comfort and handling. The 1.6 HDi variant typically came equipped with ventilated front disc brakes and solid rear discs. The braking system was adequate for the vehicle’s weight and performance, with ABS providing additional safety. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering. The suspension tuning was geared towards comfort, resulting in a smooth ride quality, even on uneven road surfaces.

Market Reception & Comparison

The Citroën C5 II 1.6 HDi 109 Airdream was generally well-received by critics for its fuel efficiency and comfortable ride. However, some reviewers noted its lack of outright performance compared to higher-powered variants. Compared to the 2.0 HDi models, the 1.6 HDi offered significantly better fuel economy but at the expense of performance. The petrol engines provided more refinement and power but were less economical. The 1.6 HDi appealed to buyers prioritizing fuel efficiency and low running costs, making it a popular choice for fleet operators and private buyers covering long distances. Reliability was generally good, although the diesel particulate filter (DPF) could be prone to clogging if the vehicle was primarily used for short journeys.

Legacy

The 1.6 HDi engine, in its various iterations, became a mainstay in the PSA Group’s lineup for many years. While generally reliable, the DV6 engine has been known to exhibit issues with the turbocharger, fuel injectors, and the DPF. Today, the C5 II 1.6 HDi 109 Airdream can be found on the used car market at relatively affordable prices. Its fuel efficiency and comfortable ride continue to appeal to budget-conscious buyers. However, potential buyers should be aware of the potential maintenance costs associated with the DPF and other common issues. The C5 II, in general, remains a comfortable and practical family car, and the 1.6 HDi variant offers a good balance of economy and usability.
