It depends on the trim: the 2019 Fusion could be powered by a 2.5-liter inline-4 gasoline engine, a turbocharged 1.5-liter EcoBoost or a turbocharged 2.0-liter EcoBoost, or, in hybrid and plug-in variants, a 2.0-liter Atkinson-cycle engine paired with electric motors.
Gasoline engine options
The gasoline-only Fusion models offered three powertrains across the lineup: a base naturally aspirated four-cylinder and two turbocharged EcoBoost options. The choice affected performance, fuel economy, and available features on different trims.
- 2.5-liter inline-4 gasoline engine (naturally aspirated)
- 1.5-liter EcoBoost turbocharged inline-4
- 2.0-liter EcoBoost turbocharged inline-4
These gasoline engines were paired with a six-speed automatic transmission in most configurations and produced varying levels of horsepower and torque depending on the engine.
Hybrid and plug-in hybrid variants
In addition to the gasoline engines, Ford offered electrified variants of the Fusion. The Hybrid and Energi plug-in hybrid combine a 2.0-liter Atkinson-cycle engine with electric motors to improve efficiency and, in the Energi, provide an electric-only driving mode for short distances.
- Fusion Hybrid: 2.0-liter Atkinson-cycle engine paired with an electric motor; does not require plugging in; front-wheel drive
- Fusion Energi (Plug-in Hybrid): 2.0-liter Atkinson-cycle engine with larger battery and electric motor; can be charged from an external power source for some electric-only range
The electrified variants were designed to maximize fuel economy, with electric assistance accompanying the gasoline engine and, in Energi, a rechargeable battery for extended electric operation.
Summary
The 2019 Ford Fusion offered a versatile engine lineup intended to balance efficiency and performance. Buyers could choose from a base 2.5L inline-4, turbocharged EcoBoost options of 1.5L or 2.0L, or opt for hybrid configurations that pair a 2.0L Atkinson-cycle engine with electric motors. Availability depended on market and trim, and the Fusion was discontinued in the U.S. after the 2019 model year.
