The third-generation Citroën C4 (code name C41) marks a deliberate stylistic break, blending compact sedan, coupe, and SUV design cues. Based on the Stellantis group's CMP/e-CMP platform (shared with the Peugeot 208/2008), it emphasizes comfort with its progressive hydraulic bump stop suspension (Advanced Comfort). Although demand for diesel is plummeting in Europe, Citroën has kept the 1.5 BlueHDi engine in its catalog for high-mileage drivers. However, this generation inherits Stellantis thermal powertrains (1.2 PureTech and 1.5 BlueHDi) which have experienced significant reliability issues, making the choice of engine and production year absolutely crucial.
