The Ford Fiesta Active VIII (Mk8) 1.0 EcoBoost 140 hp model, produced from March 2018 to June 2020, represents a specific configuration within the broader Mk8 Fiesta Active range. Positioned as a mid-range offering, it blended the practicality of a supermini hatchback with the slightly raised ride height and rugged styling cues of a crossover. This variant aimed to appeal to buyers seeking a fuel-efficient, yet reasonably powerful, and stylish vehicle for both urban and occasional rural driving. It was a key part of Ford’s strategy to offer a diverse Fiesta lineup catering to a wide spectrum of customer preferences within the European market, though limited imports were available in North America through grey market channels.

Powertrain & Engine Architecture
The heart of the Fiesta Active 1.0 EcoBoost 140 is the Ford EcoBoost 1.0-liter three-cylinder turbocharged gasoline engine, specifically the YYJE or YYJG engine codes. This engine is a marvel of downsizing technology, utilizing direct fuel injection, a single scroll turbocharger, and variable valve timing to deliver a substantial power output from a small displacement. The engine’s aluminum block and cylinder head contribute to its relatively lightweight construction. The 140 hp variant featured a revised turbocharger and engine management system compared to lower-powered EcoBoost versions. The engine is transversely mounted at the front of the vehicle. The six-speed manual transmission was standard, offering precise shifts and contributing to the car’s overall efficiency. The transmission’s gear ratios were tuned to balance acceleration with fuel economy, providing adequate performance in both city and highway driving.
Driving Characteristics
The 1.0 EcoBoost 140 hp engine provided a surprisingly lively driving experience for a supermini. While not a performance car, it offered sufficient power for confident overtaking and merging onto highways. The turbocharger provided a noticeable boost in torque from around 1500 rpm, resulting in good responsiveness. However, the engine did require some revving to access its peak power. Compared to the lower-powered 1.0 EcoBoost variants, the 140 hp version felt significantly more capable, especially when fully loaded or tackling uphill climbs. The manual transmission allowed for greater driver control, but the relatively long gearing meant that the engine sometimes felt strained at higher speeds. The Active’s slightly raised suspension provided a more comfortable ride than the standard Fiesta, absorbing bumps and imperfections in the road more effectively.
Equipment & Trim Levels
The Fiesta Active 1.0 EcoBoost 140 typically came equipped with a generous level of standard features. These included air conditioning, a touchscreen infotainment system with Bluetooth connectivity, alloy wheels, and a leather-wrapped steering wheel. The Active trim also added unique exterior styling elements, such as rugged body cladding and roof rails, giving it a more adventurous appearance. Optional extras included a rear-view camera, parking sensors, heated front seats, and a premium sound system. Interior upholstery was typically cloth, with higher trims offering partial leather options. The dashboard layout was modern and functional, with a focus on ease of use.
Chassis & Braking
The Fiesta Active featured a MacPherson strut front suspension and a twist-beam rear suspension. The Active trim level often included a slightly raised ride height compared to the standard Fiesta, improving ground clearance for navigating rougher terrain. Braking duties were handled by ventilated front discs and solid rear discs, providing adequate stopping power for the vehicle’s weight and performance. Anti-lock Braking System (ABS) was standard, enhancing safety during emergency braking situations. The steering was electrically assisted, offering a light and precise feel.
Market Reception & Comparison
The Fiesta Active 1.0 EcoBoost 140 was generally well-received by automotive critics. It was praised for its fuel efficiency, surprisingly punchy engine, and comfortable ride. However, some reviewers noted that the engine could be a bit noisy under hard acceleration. Compared to the lower-powered EcoBoost variants, the 140 hp version offered a significant improvement in performance, making it a more appealing option for drivers who frequently travel on highways or carry passengers. Against competitors like the Volkswagen Polo and Opel/Vauxhall Corsa, the Fiesta Active offered a compelling combination of style, practicality, and value.
Legacy
The 1.0 EcoBoost engine has proven to be a remarkably reliable powertrain, with many examples exceeding high mileage without major issues. However, like any turbocharged engine, it requires regular maintenance, including oil changes and spark plug replacements. The Fiesta Active 1.0 EcoBoost 140 remains a popular choice in the used car market, offering a good balance of affordability, fuel efficiency, and practicality. Its relatively small size and nimble handling make it well-suited for urban environments, while its comfortable ride and decent performance make it capable of longer journeys. The engine’s continued presence in later Ford models demonstrates its enduring appeal and technological significance.
