The Ford Focus IV, produced from 2018 to 2022, represented a significant evolution for Ford’s globally popular compact car. The facelifted model introduced in 2022 brought styling updates and revised technology. Among the engine options available, the 1.0 EcoBoost 100 horsepower variant, paired with a six-speed automatic transmission, occupied an important position as an entry-level offering, particularly in European markets. This configuration aimed to balance affordability with reasonable fuel efficiency and ease of use, appealing to buyers prioritizing practicality over outright performance. Production of this specific variant ran from January 2022 until the end of the Focus IV’s production run.

Powertrain & Engine Architecture
The heart of this Focus variant is the 1.0 EcoBoost engine, specifically the B3DA code. This is a three-cylinder, 1.0-liter turbocharged gasoline engine. It utilizes direct fuel injection, a technology that improves fuel efficiency and reduces emissions by injecting fuel directly into the combustion chamber. The engine also features a twin independent variable camshaft timing (Ti-VCT) system, allowing for optimized valve control for improved performance and efficiency across the rev range. The turbocharger, coupled with an intercooler, provides a boost in power despite the small displacement. The six-speed automatic transmission is a conventional torque-converter type, chosen for its smoothness and ease of use, although it doesn’t offer the same level of efficiency as a dual-clutch transmission.
Driving Characteristics
The 1.0 EcoBoost 100 hp automatic Focus delivers adequate performance for everyday driving. Acceleration from 0-60 mph takes around 11.5 seconds, and top speed is 115.58 mph. While not sporty, the engine provides sufficient torque (170 Nm) for comfortable cruising and overtaking. The automatic transmission is programmed for fuel economy, meaning it will upshift quickly to maintain lower engine speeds. This can sometimes result in the engine feeling strained when accelerating, particularly when fully loaded. Compared to the manual version of the same engine, the automatic offers less driver engagement but greater convenience. Higher-output EcoBoost variants (125 hp and 155 hp) and diesel options provide significantly more performance, but at a higher price point.
Equipment & Trim Levels
The 1.0 EcoBoost 100 hp automatic typically came as a base or mid-range trim level, depending on the specific market. Standard equipment generally included air conditioning, power windows, a basic infotainment system with Bluetooth connectivity, and several safety features like ABS, ESP, and multiple airbags. Higher trim levels added features such as alloy wheels, a more advanced infotainment system with navigation, parking sensors, and climate control. Interior upholstery was typically cloth, with options for upgraded materials on higher trims.
Chassis & Braking
The Focus IV utilizes an independent McPherson strut suspension at the front and an independent multi-link suspension at the rear, providing a good balance between ride comfort and handling. The 1.0 EcoBoost models generally featured smaller brakes – ventilated discs at the front and solid discs at the rear – adequate for the vehicle’s weight and power output. Anti-lock braking system (ABS) and Electronic Stability Program (ESP) were standard safety features.
Market Reception & Comparison
The 1.0 EcoBoost automatic Focus was generally well-received as a practical and economical choice. Critics praised its fuel efficiency and comfortable ride, but some noted the engine could feel underpowered, especially when carrying passengers or cargo. Compared to the 1.5 EcoBoost or diesel variants, it offered lower running costs but less performance. Its fuel economy figures of 43.6 – 36.8 US mpg combined were competitive within its segment. Reliability was generally good, although some owners reported minor issues with the turbocharger and automatic transmission.
Legacy
The 1.0 EcoBoost engine proved to be a popular choice in the Focus IV, and the combination with the automatic transmission offered a convenient and fuel-efficient option for buyers. On the used car market, these models represent a good value proposition, offering a well-equipped and reliable compact car at a reasonable price. While not the most exciting version of the Focus, the 1.0 EcoBoost automatic remains a practical and economical choice for those seeking a comfortable and efficient daily driver. Long-term reliability is generally considered good, but regular maintenance, including oil changes and turbocharger inspections, is crucial to ensure continued performance.
