The third-generation MINI Convertible (code name F57) marks a major technological break with its predecessor (R57). Based on BMW's modular UKL platform, it abandons the capricious 'Prince' engines (PSA/BMW) in favor of the modular B-family blocks (B37/B47 for diesel, B38/B48 for gasoline). Although demand for diesel convertibles has become anecdotal (leading to their withdrawal from the catalog around 2019), the Cooper D and Cooper SD versions appealed to high-mileage drivers thanks to frugal consumption and generous torque. The model benefited from two facelifts (LCI in 2018 with 'Union Jack' lights, and LCI 2 in 2021). Overall, the F57 is a very accomplished premium vehicle, whose reliability has made a giant leap compared to previous generations, despite some peripheral weaknesses (engi
The MINI Convertible F57 is undoubtedly the most reliable generation ever produced. If you specifically target a diesel (Cooper D or SD), you will benefit from exceptional range and very pleasant torque. However, buying a used diesel requires absolute vigilance regarding the history of the EGR cooler (BMW recall) and necessitates regular road use to avoid DPF clogging. For purely 'pleasure' or urban use, the gasoline engines (Cooper or Cooper S) are infinitely more relevant, more reliable for short trips, and offer a sound much more in line with open-top driving.
