Powertrain & Engine Architecture
At the heart of the C5 X 1.6 PureTech Plug-in Hybrid lies the EP6FDT engine, a 1.6-liter turbocharged inline-four cylinder petrol engine. This engine utilizes direct fuel injection and a turbocharger with an intercooler to deliver 180 horsepower at 6000 rpm and 250 Nm (184.39 lb-ft) of torque at 1750 rpm. The engine features a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. Coupled with this is an 80 kW (110 hp) electric motor integrated between the engine and the eight-speed e-EAT automatic transmission. The electric motor produces 320 Nm (236.02 lb-ft) of torque. The combined system output is 225 horsepower and 360 Nm (265.52 lb-ft) of torque. The e-EAT8 transmission is specifically tuned for hybrid applications, offering smooth and efficient gear changes. The 12.4 kWh lithium-ion battery pack provides an all-electric range of 59-60 km (36.66 – 37.28 miles) according to WLTP standards.
Driving Characteristics
The C5 X 1.6 PureTech Plug-in Hybrid offers a refined and comfortable driving experience. In electric mode, the vehicle provides near-silent operation and instant torque, making it ideal for urban driving. When the petrol engine engages, the transition is seamless. The combined power output delivers brisk acceleration, achieving 0-60 mph in approximately 7.5 seconds. The e-EAT8 transmission is well-matched to the engine, providing smooth gear changes and contributing to overall efficiency. Compared to non-hybrid C5 X variants, this model offers superior fuel economy and reduced emissions. However, the added weight of the battery pack does slightly impact handling compared to lighter models. The gear ratios are optimized for both electric and hybrid driving, prioritizing efficiency without sacrificing performance.
Equipment & Trim Levels
The 1.6 PureTech Plug-in Hybrid variant typically came with a high level of standard equipment. This included features like Citroën’s Advanced Comfort suspension, which utilizes hydraulic cushions to absorb bumps and provide a smooth ride. Interior appointments included comfortable seating, a modern dashboard layout with a 12-inch touchscreen infotainment system, and digital instrument cluster. Standard safety features included automatic emergency braking, lane keeping assist, and adaptive cruise control. Optional extras included a panoramic sunroof, premium audio system, and leather upholstery. The trim level generally positioned this variant as a premium offering within the C5 X range.
Chassis & Braking
The C5 X features an independent suspension system, with a McPherson strut setup at the front and a multi-link setup at the rear. This configuration provides a good balance of comfort and handling. The braking system consists of ventilated discs at the front and solid discs at the rear, providing adequate stopping power. ABS (Anti-lock Braking System) is standard. The suspension is tuned to prioritize ride comfort, and the chassis is designed to minimize noise and vibration. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The Citroën C5 X 1.6 PureTech Plug-in Hybrid was generally well-received by critics for its unique styling, comfortable ride, and efficient powertrain. However, some reviewers noted that the interior, while modern, lacked the premium feel of some competitors. Compared to the petrol-only C5 X variants, the plug-in hybrid offered significantly improved fuel economy and lower emissions, making it an attractive option for environmentally conscious buyers. Compared to other plug-in hybrid crossovers and wagons, the C5 X offered a distinctive design and a focus on comfort. Its fuel economy figures of 1.3-1.4 l/100 km were competitive within its segment.
Legacy
The Citroën C5 X, while a relatively short-lived model, represents Citroën’s attempt to create a unique and comfortable vehicle that blends multiple body styles. The 1.6 PureTech Plug-in Hybrid powertrain is generally considered reliable, although, as with any hybrid vehicle, the long-term durability of the battery pack is a consideration. On the used car market, these models are likely to appeal to buyers seeking a comfortable, efficient, and distinctive vehicle. The combination of a petrol engine and electric motor provides flexibility and reduces running costs, making it a viable option for those considering a plug-in hybrid.
