HyBoost demonstrator debuts at LCV2011; 50% by swept volume downsizing with low-cost electrification

Green Car Congress

In implementing this 50% downsizing by swept volume, the research team delivered zero degradation in driveability, performance or acceleration. Earlier post.). The HyBoost concept is based on a 2009 Ford Focus in which a 2.0L naturally aspirated four-cylinder gasoline engine has been replaced with a 1.0L three-cylinder EcoBoost engine.
