Ford’s Fiesta SFE is the product that puts the Eco in Ecoboost. Unlike the other Ford turbocharged products that are big on boost and a little shy on eco, this 1.0L three cylinder turbo compact hatch delivered the best fuel economy I’ve experienced in a non-hybrid. Averaging between 39 and 43 MPG in mixed driving, the Fiesta SFE wasn’t just more fuel efficient than the regular Fiesta SE, it was also faster to 60 and more fun to drive as well.
