The second-generation MINI Convertible (code name R57) succeeds the R52, retaining its neo-retro charm while modernizing its underpinnings and powertrains. Launched in early 2009, it introduced the famous 'Always Open' gauge (which calculates the time spent with the top down) and a concealed active roll bar, greatly improving the car's lines compared to the previous generation. Under the hood, it abandoned the Tritec (Chrysler) blocks for the 'Prince' engine family co-developed by BMW and PSA. While these gasoline engines offer excellent driving pleasure and controlled consumption, the first versions (2009-2010) were plagued by serious reliability issues (timing chain, oil consumption). The late 2010 facelift (LCI) introduced more reliable blocks (N16/N18) that transform the buying experie
The MINI Convertible R57 is a car with two faces. Models produced between 2009 and late 2010 (N12 engines and especially N14 on the Cooper S) are veritable financial headaches due to major design flaws (timing chain, oil consumption). They should be avoided, unless the engine has been completely rebuilt with supporting invoices. In contrast, the facelifted (LCI) versions from 2011 onwards, equipped with N16 and N18 engines, offer entirely acceptable reliability and allow full enjoyment of this MINI's exceptional chassis. Prioritize a Cooper S N18 (184 hp) with a clear service history and annual oil changes. Avoid diesels, which are ill-suited to the philosophy of a pleasure convertible and prone to timing chain failures (N47).
