The smallest engine inFordhistory is also one of its most award-winning, oddly enough, but looking at the spec charts, you start to understand why.The 1.0-liter EcoBoost inline-three, codenamed “Fox,” offered far more grunt than its naturally aspirated four-cylinder equivalents, as well as much-improved fuel economy. And weighing in at around 220 pounds with remarkably compact proportions, it proved to be an ideal powertrain for its intended new home in the Blue Oval’s entry-level sedans, hatchbacks, and crossovers. Ford even went so far as to pack the engine block inside a carry-on bag, strolling through TSA and boarding a plane with a three-cylinder in tow, a memorable stunt that presaged the Fox’s US debut in the 2014 Fiesta.
