1.0L EcoBoost DOHC I-3 (Ford Fiesta)
Apparently there is a replacement for displacement and that comes with turbocharging. A small, three-cylinder engine will soon be offered in the Ford Fiesta. What makes the 1.0-liter EcoBoost engine so good? Engineers make it function without a balance shaft, helping to resolve the usual NVH issues found in three-cylinder engines. Of course there’s the fact that the engine is extremely fuel-friendly and is rated to get 45 mpg on the highway.
