The second-generation MINI Cabriolet (codename R57) succeeds the R52, adopting the R56 sedan's platform. It stands out with the integration of active roll-over bars (invisible when retracted), a soft top that opens in 15 seconds (with a sunroof function), and the introduction of the 'Always Open Timer' gadget. Positioning & Evolution: Initially launched with 'Prince' petrol engines (co-developed with PSA), the R57 received a facelift (LCI) in summer 2010. It was at this point that it introduced, for the first time on the convertible, diesel engines (Cooper D, then Cooper SD in 2011), equipped with BMW engines from the N47 family. Expert's overall rating: Although very endearing, dynamic, and fuel-efficient in its diesel versions, the R57 suffers from capricious mechanical reliability. The
Buying a MINI Cabriolet R57 with a diesel engine (Cooper D or SD) is a purely rational choice for those who drive a lot, but it somewhat contradicts the hedonistic philosophy of a convertible (rough sound, vibrations). The expert's verdict: If you opt for a diesel, caution is advised. The BMW N47 engine is notoriously famous for its timing chain failures. Never buy this model without a complete service history and, ideally, an invoice proving that the timing chain kit has already been replaced with the reinforced version. If you drive less than 15,000 km/year, prefer a petrol version (Cooper 122 hp or Cooper S N18 post-2010), which is much more suited to the model's spirit.
