From the article: "The new, smaller engine was originally built to offer better fuel efficiency in the new Fusion..." This is NOT true. The new engine was developed to eliminate a higher tax on vehicles sold in China. China has higher taxes on vehicles with engines larger than 1.5L. It most certainly was NOT developed for greater efficiency over the 1.6L.
Ford's New 1.5-Liter Engine Gets Same Fuel Economy as 1.6-Liter
In the ever-continuing race to improve fuel efficiency, Ford has introduced a new 1.5-liter, four-cylinder EcoBoost engine in the new 2014 Ford Fusion, replacing the 1.6-liter four-cylinder from last year. However, looking at the actual mpg ratings, the new engine offers the same fuel economy as the previous Fusion's 1.6-liter, four-cylinder EcoBoost engine. Looking at these numbers, we can't help but ask ourselves the question, "What happened?" The new, smaller engine was originally built to offer better fuel efficiency in the new Fusion, but it looks like the automaker's efforts were in vain. Based off features from the 1.0-liter EcoBoost engine, the 1.5-liter has a water-cooled, integrated exhaust manifold, and has cylinder heads that have been cast in a single unit with the exhaust manifold to reduce weight, simplify the assembly process, and have the turbocharger closer to the exhaust ports. These features improve responsiveness, and supposedly, fuel economy. In a statement made earlier this year, Ford said, "The 1.5-liter engine is projected to deliver approximately the same power and torque as the 1.6-liter in the 2013 Ford Fusion, while improving fuel economy and providing improved drivability." As far as fuel economy is concerned, the new engine doesn't meet the expectations placed upon it. Until we get behind the wheel, we can't say if the improvements to drivability make up for it.
