If you have been car shopping sometime in the past 18 months or so, then you have probably heard the term "EcoBoost" from a Ford salesman. The engine has become very popular since being introduced and with Ford promising smaller and more fuel efficient engines, their domination of the market isn't likely to change.
The EcoBoost engine lineup all work on the principal of turbo-charging to increase power and decrease the engine size. The plan began with reducing the number of V6 engines being used in the lineup, and replacing them with 4 cylinder EcoBoost engine. The next step was to reduce the size of the inline-4s already being used and make them even more efficient.
The final step, at least as far as we know, is to bring the size of the engines down even more. The goal is set somewhere in the range of 1.0 liters for most of the lineup, meaning only three cylinders will be needed and power will likely be similar to the 1.6 liter engine currently being used in the Fiesta.
While the smallest EcoBoost to date has not yet been officially green-lighted, it would make sense for Ford to move forward with it.Auto Blog Green
