2018-2021 Ford Fiesta Active VIII (Mk8) 1.0 EcoBoost (100 Hp)

The Ford Fiesta Active VIII (Mk8) 1.0 EcoBoost 100 hp model, produced from March 2018 to 2021, represents a key variant within the eighth generation of Ford’s globally successful Fiesta. Positioned as an entry-level offering within the Active sub-model range – Ford’s attempt to blend hatchback practicality with crossover styling – this version aimed to provide a fuel-efficient and affordable option for buyers seeking a versatile and modern small car. It sat below the more powerful EcoBoost variants and the diesel options in the Fiesta lineup, targeting cost-conscious consumers and those prioritizing economy over outright performance. The Fiesta Mk8, built on the B746 platform, was a significant redesign for the Fiesta, incorporating updated technology, improved safety features, and a refreshed design language.

Technical Specifications

Powertrain & Engine Architecture

The heart of this Fiesta variant is the 1.0-liter EcoBoost three-cylinder engine, specifically utilizing engine codes such as SFJE, SFJF, SFJH, SFJJ, SFJK, SFJN, and SFJP depending on the specific production year and market. This engine is a marvel of downsizing technology, employing a turbocharger and direct fuel injection to deliver a surprising amount of power from such a small displacement. The direct injection system, operating at pressures up to 200 bar, ensures precise fuel delivery and efficient combustion. The engine features a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder, optimizing gas flow for improved performance. The 100 hp output is achieved between 4500 and 6500 rpm, while the peak torque of 170 Nm (125 lb-ft) is available from a low 1500 rpm, providing good responsiveness in everyday driving situations. The engine is transversely mounted at the front of the vehicle. The Fiesta Active 1.0 EcoBoost typically paired with a six-speed manual transmission, although an optional six-speed automatic transmission was also available, impacting the driving experience and fuel economy.

Driving Characteristics

The 1.0 EcoBoost 100 hp Fiesta Active, particularly when equipped with the manual transmission, offers a surprisingly engaging driving experience. While not a performance-oriented model, the turbocharger provides a noticeable boost in power, making overtaking and merging onto highways manageable. The 0-60 mph time of around 10.5 seconds is respectable for a car in this class. The six-speed gearbox allows for efficient cruising at highway speeds, while the relatively low weight of the Fiesta contributes to its nimble handling. The automatic transmission, while offering convenience, does slightly diminish the responsiveness and fuel economy compared to the manual. Gear changes are generally smooth, but can sometimes feel hesitant during quick acceleration. The Active trim’s slightly raised suspension and reinforced tires provide a more comfortable ride on uneven surfaces, but also introduce a bit more body roll in corners.

Equipment & Trim Levels

The Fiesta Active trim level, even in its base 1.0 EcoBoost 100 hp configuration, offered a decent level of standard equipment. This typically included air conditioning, power windows, power door locks, a basic audio system with Bluetooth connectivity, and alloy wheels. Safety features such as ABS, electronic stability control, and multiple airbags were also standard. Optional extras included a touchscreen infotainment system with navigation, Apple CarPlay and Android Auto compatibility, a rear-view camera, parking sensors, and upgraded interior trim materials. The interior typically featured cloth upholstery and a functional, if somewhat basic, dashboard layout. The Active trim also distinguished itself with unique exterior styling elements, such as rugged plastic cladding around the wheel arches and sills, giving it a more crossover-like appearance.

Chassis & Braking

The Fiesta Active utilizes a MacPherson strut front suspension and a twist-beam rear suspension. The Active trim level often featured a slightly raised ride height compared to standard Fiesta models, providing increased ground clearance for navigating rougher terrain. The braking system consists of ventilated discs on the front wheels and solid discs on the rear. ABS (Anti-lock Braking System) is standard, providing enhanced braking performance and stability. The steering is electrically assisted, offering a light and precise feel. The tires are typically 205/45 R17, providing a good balance between grip and rolling resistance.

Market Reception & Comparison

The Fiesta Active 1.0 EcoBoost 100 hp was generally well-received by automotive critics as a practical and economical choice. It was praised for its fuel efficiency, nimble handling, and surprisingly refined engine. However, some reviewers noted that the engine could feel strained when fully loaded or driving uphill. Compared to the higher-output EcoBoost variants, this version offered less outright performance, but at a lower price point. Compared to the diesel models, it provided a smoother and quieter driving experience, but with slightly higher running costs. Fuel economy figures of around 5 liters per 100 km (47 US mpg) were considered competitive for its class.

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’s important to adhere to recommended maintenance schedules, including regular oil changes and inspections of the turbocharger and cooling system. The Fiesta Mk8, and specifically this 1.0 EcoBoost variant, remains a popular choice on the used car market due to its affordability, fuel efficiency, and practicality. Its blend of hatchback versatility and crossover styling continues to appeal to a wide range of buyers. While newer models offer more advanced technology and features, the Fiesta Active 1.0 EcoBoost represents a solid and dependable option for those seeking a well-rounded small car.
