The Ford Fiesta Mk8, specifically the three-door variant equipped with the 1.0 EcoBoost 125 horsepower engine and PowerShift automatic transmission, represents a significant iteration in Ford’s long-running supermini lineage. Introduced in late 2021 as part of the facelift for the Mk8 generation, this model aimed to balance fuel efficiency with a reasonable level of performance, appealing to buyers seeking a practical and economical city car. Production continued until July 2023, marking the end of Fiesta production after over four decades. This particular configuration sat in the mid-range of the Fiesta lineup, offering more power and refinement than the base models but remaining more accessible than the higher-specification ST trims.

Powertrain & Engine Architecture
The heart of this Fiesta variant is the Ford 1.0 EcoBoost B7JB engine, a three-cylinder turbocharged gasoline engine. This engine is part of Ford’s EcoBoost family, known for its combination of small displacement, turbocharging, and direct fuel injection. The 125 horsepower output is achieved through a sophisticated combination of technologies, including a twin-scroll turbocharger, high-pressure fuel injection, and variable valve timing. The engine utilizes a 10.5:1 compression ratio and a DOHC (Double Overhead Camshaft) valvetrain. The ‘mild hybrid’ aspect comes from a small integrated starter generator (ISG) that provides a boost during acceleration and enables start-stop functionality, improving fuel economy. The PowerShift transmission is a 7-speed dual-clutch transmission (DCT) offering quicker and smoother shifts compared to a traditional automatic. It’s designed to enhance both performance and fuel efficiency.
Driving Characteristics
The 1.0 EcoBoost 125 hp with PowerShift provides a surprisingly lively driving experience for a supermini. While not as quick as the higher-output ST models, it offers sufficient power for everyday driving and overtaking maneuvers. The PowerShift transmission contributes to this, providing responsive gear changes. Acceleration from 0-60 mph takes approximately 9.1 seconds. The DCT’s programming prioritizes fuel efficiency, meaning the transmission can sometimes feel hesitant to downshift quickly when aggressive acceleration is demanded. Compared to the manual transmission versions of the same engine, the PowerShift offers greater convenience, particularly in urban environments, but may sacrifice a small degree of driver engagement. The mild hybrid system is largely imperceptible during normal driving, providing a subtle boost during acceleration.
Equipment & Trim Levels
The 1.0 EcoBoost 125 hp PowerShift Fiesta typically came equipped with features such as air conditioning, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, alloy wheels, and a suite of safety features including lane-keeping assist and automatic emergency braking. Higher trim levels added features like a larger touchscreen, heated seats, a rear-view camera, and parking sensors. Interior upholstery was typically cloth, with options for upgraded materials. The dashboard layout was modern and functional, with a focus on ease of use.
Chassis & Braking
The Fiesta Mk8 utilizes a McPherson strut front suspension and a torsion beam rear suspension. This setup provides a good balance between ride comfort and handling. The front brakes are ventilated discs, while the rear brakes are drums, a cost-saving measure common in this segment. The steering is electric power-assisted, offering a light and precise feel. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering. The suspension tuning is geared towards providing a comfortable ride for everyday driving, rather than outright sporty handling.
Market Reception & Comparison
The 1.0 EcoBoost 125 hp PowerShift Fiesta was generally well-received by automotive critics. It was praised for its fuel efficiency, refined engine, and comfortable ride. However, some reviewers noted that the PowerShift transmission could be occasionally jerky at low speeds. Compared to the 1.0 EcoBoost 100 hp version, the 125 hp model offered a noticeable performance improvement. Against competitors like the Volkswagen Polo and Opel Corsa, the Fiesta offered a compelling package with a strong focus on driving dynamics and technology. Fuel economy figures of 5.3-6.1 l/100km were competitive within its class.
Legacy
The 1.0 EcoBoost engine has proven to be a reliable and durable powertrain, although the PowerShift transmission has been subject to some reported issues, particularly in earlier iterations. Proper maintenance, including regular oil changes and transmission fluid services, is crucial for ensuring long-term reliability. On the used car market, the 1.0 EcoBoost 125 hp PowerShift Fiesta represents a good value proposition, offering a blend of practicality, efficiency, and affordability. Its relatively low running costs and enjoyable driving experience continue to make it a popular choice for urban commuters and first-time car buyers.
