The Mini Cooper R57 is the second-generation convertible model, produced from 2009 to 2015. Known for its iconic design and exhilarating driving experience, the R57 offered open-air motoring with a blend of classic MINI styling and modern technology. This guide provides a detailed overview of the R57, covering its key features, model variations, and common issues.
Identifying Your MINI Cooper: Understanding R and F Chassis Codes
Many MINI owners are unsure about their car’s specific model designation. MINI uses chassis codes to differentiate between generations and body styles. Understanding these codes can be helpful when searching for parts or researching your MINI.
BMW, MINI’s parent company, uses “R” for the first and second-generation MINIs (GEN1 and GEN2) and “F” for the third generation (GEN3). A two-digit number follows the letter, indicating the specific chassis type. For example, the R57 denotes the second-generation convertible. Other R-type chassis codes include R50, R52, R53, R55, R56, R58, R59, R60, and R61. F-type chassis codes include F54, F55, F56, F57, and F60.
