The Citroën C5 II (Phase II), specifically the 1.6 THP 156 horsepower variant produced between 2012 and 2015, represents a mid-cycle refresh of the second-generation C5. Positioned as a mainstream offering within the C5 lineup, this model aimed to balance performance, fuel efficiency, and comfort in the large family car segment. It was primarily marketed in Europe, where Citroën held a strong presence, offering a more affordable and efficient alternative to larger-engined models while still providing a refined driving experience. The Phase II updates included styling revisions, improved interior materials, and enhancements to the suspension system, building upon the foundation of the C5 II platform (based on the PSA Group’s EMP2 architecture).

Powertrain & Engine Architecture
The heart of this C5 variant is the 1.6 THP (Turbo High Pressure) engine, specifically the 5FV EP6CDT code. This engine is a member of the Prince engine family, a collaborative development between PSA Group (Peugeot Citroën) and BMW. It’s a 1.6-liter inline-four cylinder engine featuring direct fuel injection and a twin-scroll turbocharger. The direct injection system, coupled with the turbocharger, allows for a high compression ratio (10.5:1) and efficient combustion, contributing to both power and fuel economy. The engine utilizes a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The six-speed manual transmission was the standard offering, chosen for its balance of efficiency and driver engagement. While an automatic transmission was available in some C5 II models, it wasn’t commonly paired with the 156 hp 1.6 THP engine.
Driving Characteristics
The 1.6 THP 156 hp engine provides a respectable level of performance for a large family sedan. Acceleration from 0 to 62 mph takes approximately 8.6 seconds, and the engine delivers a maximum torque of 240 Nm (177 lb-ft) available from a low 1400 rpm. This provides good responsiveness for everyday driving situations, such as overtaking and merging onto highways. Compared to the more powerful 2.0-liter HDi diesel variants, the 1.6 THP offers less outright acceleration but feels more eager to rev. The manual transmission’s gear ratios are well-matched to the engine’s powerband, allowing for smooth and efficient cruising. The C5’s renowned hydropneumatic suspension (though evolving towards more conventional setups in later years) contributes to a comfortable and composed ride, even on uneven road surfaces.
Equipment & Trim Levels
The 1.6 THP 156 hp variant typically occupied a mid-range position in the C5 II lineup. Standard equipment generally included air conditioning, power windows, central locking, a CD/radio system, and basic safety features like ABS and airbags. Higher trim levels, such as Exclusive, added features like leather upholstery, automatic climate control, parking sensors, and a more advanced infotainment system. Optional extras included a panoramic sunroof, navigation system, and upgraded audio systems. Interior upholstery was typically cloth in the base models, with leather options available on higher trims. The dashboard layout was functional and ergonomically designed, prioritizing ease of use.
Chassis & Braking
The C5 II features an independent suspension system on both the front and rear axles, contributing to its comfortable ride quality. The front suspension utilizes a multi-link setup, while the rear also employs a multi-link design. Braking duties are handled by ventilated discs on the front wheels and solid discs on the rear. ABS (Anti-lock Braking System) is standard. The C5’s chassis is designed to prioritize comfort and stability over outright sportiness, resulting in a predictable and reassuring handling experience. The steering is electrically assisted, providing a light and easy feel.
Market Reception & Comparison
The Citroën C5 II 1.6 THP 156 hp was generally well-received by automotive critics as a competent and comfortable family car. It was praised for its fuel efficiency, refined engine, and comfortable ride. However, some critics noted that the engine could feel strained when fully loaded or driving uphill. Compared to the diesel variants, the 1.6 THP offered lower running costs in terms of fuel but potentially higher maintenance costs due to the complexity of the turbocharger and direct injection system. The 1.6 THP was often seen as a good compromise for drivers who wanted a balance of performance and economy.
Legacy
The 1.6 THP engine, while generally reliable, has been known to exhibit some issues related to carbon buildup on the intake valves, particularly with infrequent oil changes or predominantly short-trip driving. The timing chain is another potential area of concern, requiring periodic inspection. However, with regular maintenance and careful driving, the powertrain can prove durable. In the used car market, the C5 II 1.6 THP 156 hp represents a relatively affordable entry point into the large family car segment, offering a good level of comfort and equipment for its price. Its fuel efficiency and refined engine make it a practical choice for everyday driving.
