The third-generation MINI (F56 for the 3-door, F55 for the 5-door introduced in 2014) marks a major turning point in the model's history. Based on BMW's modular UKL platform, it definitively abandons powertrains shared with PSA (Prince gasoline engines and DV/N47 diesels) in favor of BMW's modular "B-Series" engine family (B37/B47 for diesel, B38/B48 for gasoline). This technical change is accompanied by a spectacular leap in reliability and finish quality. The model underwent two facelifts (LCI in 2018 with the arrival of Union Jack taillights and DKG dual-clutch gearboxes, then LCI 2 in 2021). Although demand for diesel significantly dropped towards the end of its career (gradual withdrawal from the catalog starting in 2019), the One D, Cooper D, and Cooper SD versions are among the most
The MINI F55/F56 is the generation of redemption. By abandoning shared mechanics for 100% BMW engines, it becomes one of the most reliable premium city cars on the market. Regarding the diesel versions (One D, Cooper D, Cooper SD), the mechanical record is excellent: the engine block itself is indestructible. However, like any modern diesel, the emission control peripherals (EGR, DPF) require appropriate use. Buy a diesel only if you drive more than 20,000 km per year with a majority of highway driving. Absolutely ensure that the EGR cooler recall campaign has been carried out at a BMW/MINI dealership. If you drive in the city, avoid diesel and opt for the excellent B38/B48 gasoline engines.
