The Mini Convertible (R57) facelift, produced from 2012 to 2015, represented a mid-cycle refresh of the second-generation convertible model. The Cooper 1.6 (122 hp) Automatic variant occupied a key position in the lineup, serving as a more accessible entry point to the Mini Convertible experience compared to the more powerful Cooper S and John Cooper Works models. This version aimed to balance the fun-to-drive character of the Mini with the convenience of an automatic transmission and reasonable fuel economy, appealing to a broader customer base. It was built on the R57 platform, sharing its underpinnings with the Mini Cooper hatchback (R56) and Clubman (R55).

Powertrain & Engine Architecture
The Cooper 1.6 Automatic variant was powered by the N16B16A engine, a 1.6-liter naturally aspirated inline-four cylinder engine. This engine was a member of the BMW/PSA Prince engine family, known for its compact design and efficiency. The N16B16A featured double VANOS (variable valve timing) on both the intake and exhaust camshafts, contributing to improved performance and fuel economy. Fuel delivery was handled by a multi-port fuel injection system. The engine produced 122 horsepower at 6000 rpm and 160 Nm (118 lb-ft) of torque at 4250 rpm. The engine was paired with a 6-speed automatic transmission, offering smooth shifts and convenience for everyday driving. This transmission was specifically tuned for the Cooper’s power output, prioritizing fuel efficiency and comfortable cruising over outright performance.
Driving Characteristics
The 1.6-liter engine with the automatic transmission delivered a comfortable and predictable driving experience. Acceleration was adequate for daily commuting and highway merging, but it wasn’t particularly brisk. The 0-60 mph time was around 10.5 seconds. The automatic transmission, while smooth, lacked the responsiveness of a manual gearbox, and didn’t offer the same level of driver engagement. Gear ratios were optimized for fuel efficiency, meaning the engine sometimes felt strained during hard acceleration. Compared to the Cooper S, which featured a turbocharged engine and significantly more power, the Cooper 1.6 Automatic felt noticeably slower. However, it offered a more relaxed and refined driving experience, particularly in urban environments.
Equipment & Trim Levels
The Cooper 1.6 Automatic typically came standard with features such as air conditioning, power windows, power locks, and a basic audio system. The convertible top was electrically operated. Interior upholstery was typically cloth, with options for leather upgrades. Common optional extras included a premium sound system, navigation system, sport seats, and various cosmetic enhancements. Trim levels were relatively simple, with the Cooper 1.6 Automatic serving as the base model for the convertible range. The focus was on providing a stylish and well-equipped vehicle at a relatively affordable price point.
Chassis & Braking
The R57 Mini Convertible utilized a McPherson strut front suspension and a multi-link rear suspension, providing a good balance of ride comfort and handling. The chassis was reinforced to compensate for the lack of a fixed roof, maintaining structural rigidity. The Cooper 1.6 Automatic featured ventilated disc brakes at the front and solid disc brakes at the rear. ABS (Anti-lock Braking System) was standard. The suspension was tuned to provide a comfortable ride, but it could also handle spirited driving on winding roads. Stabilizer bars were fitted front and rear to reduce body roll.
Market Reception & Comparison
The Mini Convertible Cooper 1.6 Automatic was generally well-received by critics as a stylish and fun-to-drive convertible. However, some reviewers noted that the engine lacked the punch of the Cooper S and that the automatic transmission wasn’t as engaging as the manual. Fuel economy was considered reasonable for a convertible, averaging around 35.6 US mpg in combined driving. Compared to other small convertibles on the market, the Mini offered a unique blend of British styling, German engineering, and a premium interior. Reliability was generally good, although some owners reported minor issues with the electrical system.
Legacy
The N16B16A engine, while not known for being exceptionally powerful, proved to be a relatively reliable unit when properly maintained. The 6-speed automatic transmission also had a good reputation for durability. Today, the R57 Mini Convertible Cooper 1.6 Automatic remains a popular choice in the used car market, particularly among buyers looking for a stylish and affordable convertible. Maintenance costs are generally reasonable, and parts availability is good. However, potential buyers should be aware of potential issues with the convertible top mechanism and the electrical system. The R57 generation helped solidify the Mini Convertible’s position as a desirable and fashionable vehicle, and it continues to be appreciated by enthusiasts for its unique character and driving experience.
