Powertrain & Engine Architecture
The heart of this Fiesta variant is the 1.0 EcoBoost BZJA engine, a three-cylinder turbocharged gasoline engine. This engine is part of Ford’s EcoBoost family, known for its downsizing and turbocharging technologies aimed at improving fuel efficiency without sacrificing performance. The BZJA utilizes direct fuel injection, a technology that precisely meters fuel into the cylinders for optimal combustion. The engine also features a double overhead camshaft (DOHC) valvetrain, contributing to efficient cylinder filling and exhaust scavenging. The turbocharger, coupled with an intercooler, boosts power output by forcing more air into the engine. The mild-hybrid system incorporates a belt-driven integrated starter generator (BiSG) which allows for start-stop functionality and regenerative braking, capturing energy during deceleration to assist the engine during acceleration. This system doesn’t provide full electric drive capability, but it does contribute to improved fuel economy. The engine is paired with a six-speed manual transmission, delivering power to the front wheels.
Driving Characteristics
The 155 horsepower output, combined with 220 Nm (162 lb-ft) of torque, provides a respectable level of performance for a supermini. Acceleration from 0 to 60 mph takes approximately 8.5 seconds, and the car reaches a top speed of 136 mph. The turbocharger provides a noticeable boost in power, but some turbo lag is present at lower engine speeds. The six-speed manual transmission offers precise shifts and allows drivers to keep the engine in its optimal power band. Compared to the lower-powered EcoBoost variants, this 155 hp version offers a more engaging driving experience, particularly during highway overtaking. However, it doesn’t match the outright performance of the Fiesta ST. The mild-hybrid system is largely transparent to the driver, providing a subtle assist during acceleration and enabling smooth start-stop operation.
Equipment & Trim Levels
The 1.0 EcoBoost 155 hp variant typically came equipped with a reasonable level of standard features. These included air conditioning, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, alloy wheels, and a suite of safety features such as lane-keeping assist and automatic emergency braking. Higher trim levels offered additional features like a larger touchscreen, a premium sound system, heated seats, and a rear-view camera. Interior upholstery was typically cloth, with options for partial leather trim on higher-spec models. 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 steering is precise and well-weighted, offering good feedback to the driver. The braking system consists of ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) and electronic stability control (ESC) are standard features, enhancing safety and control. The relatively lightweight construction of the Fiesta contributes to its agile handling characteristics.
Market Reception & Comparison
The 1.0 EcoBoost 155 hp Fiesta was generally well-received by automotive critics. It was praised for its fuel efficiency, responsive engine, and engaging driving dynamics. However, some reviewers noted the presence of turbo lag and the slightly firm ride. Compared to the 1.0 EcoBoost 100 hp variant, the 155 hp version offered a significant performance upgrade, making it a more appealing option for drivers who prioritize driving enjoyment. Compared to the diesel-powered Fiesta models, the EcoBoost offered a smoother and quieter driving experience, albeit with slightly higher fuel consumption in some scenarios.
Legacy
The 1.0 EcoBoost engine has proven to be a reliable and durable powertrain, although some early versions were prone to issues with timing belt wear. Regular maintenance, including oil changes and timing belt inspections, is crucial for ensuring long-term reliability. In the used car market, the 1.0 EcoBoost 155 hp Fiesta represents a good value proposition, offering a blend of performance, efficiency, and features. Its compact size and nimble handling make it a popular choice for urban driving, while its highway capabilities make it suitable for longer journeys. The Fiesta Mk8, in general, remains a well-regarded supermini, and this particular variant continues to be a sought-after option for buyers looking for a fun-to-drive and economical car.
