The Mini Coupe (R58) Cooper SD 2.0 Automatic, produced between 2011 and 2015, represented a unique offering within the second-generation Mini lineup (R56). Positioned as a sporty, two-seater coupe derived from the standard Mini Hatch, the Cooper SD variant combined a fuel-efficient diesel engine with the convenience of an automatic transmission. This model aimed to appeal to drivers seeking a distinctive and economical grand tourer, albeit one with limited practicality due to its two-seat configuration. It was built on the Mini’s familiar 1HX0/A3 platform, sharing many components with the Hatch and Convertible models, but distinguished by its sloping roofline and overall coupe aesthetic.

Powertrain & Engine Architecture
The Cooper SD 2.0 Automatic was powered by the BMW N47C20 engine, a 2.0-liter inline-four diesel engine. This engine was a mainstay in many BMW and Mini models of the era, known for its blend of efficiency and performance. The N47 featured common-rail direct injection, a turbocharger with an intercooler, and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The engine produced 143 horsepower at 4000 rpm and a substantial 305 Nm (224.96 lb-ft) of torque between 1750 and 2700 rpm. The automatic transmission was a six-speed unit, providing smooth shifts and contributing to the car’s ease of driving. The N47 engine was known for its relatively complex design, including a timing chain that, in early iterations, was prone to failure, a point that would become relevant in the vehicle’s long-term reliability.
Driving Characteristics
The 2.0-liter diesel engine, coupled with the six-speed automatic, provided a relaxed and efficient driving experience. Acceleration from 0 to 60 mph took around 7.8 seconds, which was respectable for a diesel-powered coupe, but noticeably slower than the petrol-powered Cooper S variants. The automatic transmission was well-matched to the engine’s torque curve, offering smooth gear changes and adequate responsiveness. However, it lacked the engagement and control offered by the manual transmission options. The car’s front-wheel-drive layout meant that traction could be a limitation under hard acceleration, particularly in wet conditions. The overall driving experience was more geared towards comfortable cruising than outright sporty performance.
Equipment & Trim Levels
The Cooper SD 2.0 Automatic typically came equipped with a reasonable level of standard features. These included air conditioning, power windows, central locking, and a basic audio system. Interior upholstery was generally cloth, although leather options were available. The dashboard layout followed the circular theme characteristic of the Mini interior, with a central speedometer and various auxiliary gauges. Optional extras included a panoramic sunroof, upgraded audio systems (often from Harman Kardon), navigation, and sport seats. The Mini Coupe, in general, offered a high degree of customization, allowing buyers to personalize their vehicles with a wide range of accessories and options.
Chassis & Braking
The Mini Coupe’s chassis utilized independent suspension all around – McPherson struts at the front and a multi-link setup at the rear. This provided a relatively comfortable ride, although it was firmer than the standard Mini Hatch due to the coupe’s sportier aspirations. Brakes consisted of ventilated discs at the front and solid discs at the rear. Anti-lock Braking System (ABS) was standard. The car’s weight distribution was reasonably balanced, contributing to its handling characteristics. The steering was electrically assisted, providing a light and precise feel.
Market Reception & Comparison
The Mini Coupe, and specifically the Cooper SD Automatic variant, received mixed reviews from automotive critics. While the styling was generally praised for its uniqueness, the two-seat configuration and limited practicality were often criticized. The diesel engine was lauded for its fuel efficiency and torque, but some reviewers found the automatic transmission to be somewhat sluggish. Compared to the petrol-powered Cooper S, the SD offered better fuel economy but less outright performance. Against other small coupes in the market, the Mini Coupe stood out for its distinctive design and premium feel, but its price point was relatively high.
Legacy
The Mini Coupe (R58) was a relatively short-lived model, discontinued in 2015. The N47 engine, while generally reliable, gained a reputation for potential timing chain issues, requiring preventative maintenance or eventual replacement on some vehicles. Today, the Cooper SD 2.0 Automatic represents an interesting and somewhat niche offering in the used car market. Its fuel efficiency and unique styling continue to appeal to some buyers, but potential owners should be aware of the potential engine issues and factor in the cost of preventative maintenance. The car remains a testament to Mini’s willingness to experiment with different body styles and powertrain combinations.
