Citroën C4 (Mk3)
The third-generation Citroën C4 swapped the traditional hatch for a raised crossover-style five-door, launched for the UK in late 2020 with deliveries from early 2021. It is built on the Stellantis CMP platform shared with the Peugeot 208 and e-208, and majors on a soft ride thanks to Progressive Hydraulic Cushions, comfortable Advanced Comfort seats and a spacious cabin with a long wheelbase. UK buyers could choose the 1.2 PureTech petrol in 100 or 130hp form, the 1.5 BlueHDi diesel and the electric ë-C4 with a 50kWh battery and about 217 miles WLTP range; a 2024 update added a mild-hybrid option and a longer-range 54kWh electric car. The C4 targets family and fleet buyers who value comfort over handling, competing with the Ford Focus and Vauxhall Astra more on price than driving fun. Wet-belt PureTech maintenance and software-related electronic quirks are the main watch points, so verify updates and belt history. Because it is a younger car, many examples are still under manufacturer warranty or offered on PCP deals.
