Ford announced plans to introduce EcoBoost engines in its redesigned 2013 Escape, Fusion, Focus, and Interceptor (used by law-enforcement agencies,) tripling the production capacity of EcoBoost-equipped vehicles to more than 383,000 vehicles in 2012. Already popular on some Ford models, the 3.5 liter V6 EcoBoost accounts for 42% of the engine mix on the F-150. Last year Ford built 127,883 vehicles with an EcoBoost engine in North America.
