2012-2015 Mini Roadster (R59) Cooper S 1.6 (184 Hp) Automatic

The Mini Roadster Cooper S 1.6 Automatic, produced between 2012 and 2015, represented a unique offering within the R59 Mini Roadster generation. Positioned as a performance-oriented variant, it combined the open-air fun of a roadster with the turbocharged punch of the 1.6-liter four-cylinder engine and the convenience of an automatic transmission. This model aimed to deliver a sporty driving experience while maintaining a degree of everyday usability, appealing to drivers seeking a more engaging alternative to the standard Cooper Roadster.

Technical Specifications

INTRODUCTION

The Mini Roadster Cooper S Automatic, launched in 2012, was a key part of Mini’s expansion into the open-top market. Built on the R59 platform – shared with the Coupe – the Roadster aimed to provide a more driver-focused experience than the standard Cooper. The “S” designation indicated a higher performance level, thanks to the turbocharged 1.6-liter engine. The availability of a six-speed automatic transmission broadened its appeal, offering a more relaxed driving experience for those who preferred not to shift gears manually. This variant sat in the middle of the Roadster lineup, offering a step up in performance from the base Cooper models while remaining more accessible than potential future JCW (John Cooper Works) versions.

Powertrain & Engine Architecture

At the heart of the Cooper S Automatic lies the N18B16A 1.6-liter inline-four cylinder engine. This engine is a direct-injection, turbocharged powerplant, a significant upgrade over the naturally aspirated engines found in earlier Mini models. The N18 features a twin-scroll turbocharger, which helps to minimize turbo lag and improve responsiveness. Direct injection delivers fuel directly into the combustion chamber, optimizing combustion efficiency and power output. The engine utilizes variable valve timing (VANOS) on both the intake and exhaust camshafts, further enhancing performance and fuel economy. The six-speed automatic transmission, sourced from Aisin, was chosen for its smooth operation and efficiency. It features a torque converter and adaptive shift programming, adjusting shift points based on driving style and conditions. While not as sporty as the available six-speed manual, the automatic provided a comfortable and convenient driving experience.

Driving Characteristics

The Cooper S Automatic delivered a noticeably more spirited driving experience than the standard Cooper Roadster. The 184 horsepower and 260 Nm (192 lb-ft) of torque provided brisk acceleration, with a 0-60 mph time of around 6.8 seconds. The automatic transmission, while smooth, did slightly diminish the sense of direct control compared to the manual version. Gear ratios were tuned for a balance of acceleration and fuel efficiency. In typical driving situations, the transmission shifted smoothly and predictably. Sport mode, if equipped, would hold gears longer and downshift more aggressively, providing a more engaging driving experience. The Roadster’s relatively short wheelbase and well-tuned suspension contributed to its agile handling, making it enjoyable to drive on winding roads. However, the automatic transmission could sometimes feel hesitant during quick downshifts.

Equipment & Trim Levels

The Cooper S Automatic came standard with a generous array of features. Interior appointments typically included sport seats upholstered in cloth or leatherette, a leather-wrapped steering wheel, and aluminum interior trim. Standard equipment also included air conditioning, power windows and locks, and a basic audio system. Optional extras were plentiful, allowing buyers to customize their Roadster to their liking. Popular options included a premium Harman Kardon audio system, navigation system, heated seats, and a panoramic sunroof. The Roadster also offered a range of exterior customization options, including different wheel designs, body colors, and stripe packages.

Chassis & Braking

The R59 Roadster utilized a McPherson strut front suspension and a multi-link rear suspension, providing a good balance of ride comfort and handling precision. The suspension was tuned to be slightly firmer than that of the standard Cooper, reflecting the Cooper S’s performance focus. Braking duties were handled by ventilated discs at the front and solid discs at the rear. Anti-lock brakes (ABS) were standard, providing enhanced stopping power and control. The Roadster’s chassis was reinforced compared to the Coupe to improve rigidity and handling. The steering system employed a rack-and-pinion setup with electric power assistance, providing precise and responsive steering feel.

Market Reception & Comparison

The Mini Roadster Cooper S Automatic received generally positive reviews from automotive critics. It was praised for its sporty handling, responsive engine, and stylish design. However, some critics noted that the automatic transmission didn’t quite match the engagement of the manual version. Compared to the standard Cooper Roadster, the Cooper S offered a significant performance upgrade. Compared to the more powerful John Cooper Works Roadster (when it became available), the Cooper S offered a more accessible price point and a slightly more comfortable ride. Fuel economy was respectable for a performance-oriented roadster, averaging around 35.6 US mpg in combined driving.

Legacy

The Mini Roadster Cooper S Automatic has proven to be a relatively reliable vehicle, with the N18 engine generally considered robust. Common issues, if any, often relate to the turbocharger or fuel injectors, but these are typically not major concerns. On the used car market, the Roadster Cooper S Automatic holds its value reasonably well, particularly well-maintained examples with low mileage. It remains a popular choice for drivers seeking a fun-to-drive, stylish, and relatively practical open-top sports car. The combination of performance, convenience, and Mini’s iconic design ensures its continued appeal to enthusiasts.
