The four-cylinder EcoBoost, under development, is called a 2.0 liter by Detroit News, though Ford spokesman Said Deep would only confirm development, not displacement or vehicle application. Detroit News also speculates that the four-cylinder will first find a home in the Ford Fusion sedan. Just as the 3.5-liter EcoBoost V-6 promises the power of a V-8 with the efficiency of a V-6, we imagine Ford will advertise the four-cylinder EcoBoost as having the power of a V-6 and the efficiency of a four.
While it might seem counterintuitive to continue costly development of fuel-efficient technologies like Ford's EcoBoost just as fuel prices are hitting surprising lows, analysts still see it as smart direction that will pay off for Ford. Not only will these engines help with meeting CAFE guidelines, they will also ensure governmental support tied to fuel economy as well as hopefully retraining American drivers to realize that smaller displacements need not yield poor performance.--Colin Mathews
