Powertrain & Engine Architecture
The heart of the One First 1.2 is the BMW-developed B38A12A 1.2-liter three-cylinder turbocharged engine. This engine is part of BMW’s modular engine family, known for its efficiency and surprisingly robust power output for its size. It utilizes direct fuel injection, delivering fuel directly into the combustion chamber for improved combustion efficiency and reduced emissions. The engine also features a single twin-scroll turbocharger with an intercooler, which minimizes turbo lag and provides a broader torque curve. The valvetrain employs four valves per cylinder, contributing to improved breathing and overall performance. The six-speed manual transmission was chosen to complement the engine’s characteristics, offering precise gear changes and a more engaging driving experience. The transmission’s gear ratios were tuned to maximize fuel economy while still providing adequate acceleration.
Driving Characteristics
The 102 horsepower and 150 Nm (110 lb-ft) of torque delivered by the One First 1.2 resulted in a 0-60 mph time of around 12.2 seconds and a top speed of 195 km/h (121 mph). While not particularly quick, the engine provided sufficient power for everyday driving situations. The turbocharger helped to mitigate the effects of the small displacement, providing a noticeable boost in power at lower engine speeds. Compared to the more powerful Cooper models, the One First 1.2 offered a more relaxed and fuel-efficient driving experience. The manual transmission allowed for greater driver control, but the relatively long gearing emphasized fuel economy over outright performance. The car felt nimble and easy to maneuver in urban environments, a hallmark of the Mini brand.
Equipment & Trim Levels
The “First” edition of the One 1.2 typically included several upgrades over the standard One model. Standard features often included air conditioning, a 6.5-inch infotainment system with Bluetooth connectivity, power windows, and central locking. The interior typically featured cloth upholstery, although leather options were available. Optional extras included a panoramic sunroof, upgraded sound system, parking sensors, and various customization options for the interior trim and exterior paint colors. The “First” trim often included unique badging and styling elements to differentiate it from other One models.
Chassis & Braking
The F56 Mini Hatch utilized a McPherson strut front suspension and a multi-link rear suspension, providing a comfortable yet sporty ride. The suspension was tuned to balance handling and ride quality, offering a good compromise for everyday driving. The One First 1.2 was equipped with ventilated front disc brakes and solid rear disc brakes. Anti-lock Braking System (ABS) was standard, enhancing braking performance and safety. The car’s relatively light weight (1085 kg / 2392 lbs) contributed to its agile handling characteristics. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The Mini One First 1.2 was generally well-received by critics as an affordable and stylish entry point into the Mini range. Its fuel economy of around 5 liters per 100 km (47 US mpg) was a significant selling point, particularly in Europe. Compared to the more powerful Cooper models, the One First 1.2 offered a lower purchase price and reduced running costs. However, some critics noted that the engine could feel strained when fully loaded or driving uphill. Reliability was generally good, although, like all turbocharged engines, it required regular maintenance and the use of high-quality oil.
Legacy
The B38 engine family has proven to be remarkably reliable, and the One First 1.2 powertrain continues to be a popular choice in the used car market. Its combination of fuel efficiency, style, and the Mini brand’s reputation for fun-to-drive characteristics makes it an attractive option for buyers seeking a small, economical hatchback. While not a performance car, the One First 1.2 provides a rewarding driving experience and remains a testament to Mini’s ability to create stylish and engaging vehicles for a wide range of drivers. Properly maintained examples continue to command reasonable prices and offer a relatively trouble-free ownership experience.
