EcoBoost

EcoBoost is Ford's marketing name for a family of turbocharged, direct-injection gasoline engines that the company began rolling out in the late 2000s. The core idea behind EcoBoost is downsizing: pairing a smaller-displacement engine with turbocharging and direct fuel injection to approach the power output of a larger naturally aspirated engine while aiming for better fuel efficiency under normal driving conditions.

The EcoBoost lineup spans a wide range of displacements and applications, from a 1.0-liter three-cylinder used in the Fiesta and Focus to a twin-turbocharged 3.5-liter V6 used in the F-150 and Raptor trucks. This range let Ford apply the same underlying technology approach across economy cars, family sedans, SUVs, and full-size trucks rather than confining turbocharging to performance models alone.

EcoBoost engines have also found their way into performance applications, including the Ford Focus RS and Mustang EcoBoost, showing that the same turbocharged, direct-injection architecture can be tuned for either efficiency or power depending on the application. The name has become one of the more recognizable engine sub-brands in the mainstream automotive market.
