What is the most fuel efficient Ford Fiesta model?

I'm looking to purchase a Ford Fiesta and I want to find the model with the best fuel efficiency. What should I look for?

The most fuel efficient Ford Fiesta model is the Fiesta SE with the EcoBoost engine. It has an EPA estimated 32 city/40 highway/35 combined MPG. It also comes with Start-Stop Technology which shuts off the engine when the vehicle is stopped, optimizing fuel efficiency.

Based on my experience, the Fiesta SE with the EcoBoost engine is definitely the way to go if you want the best fuel efficiency. Don't forget to also keep your tires properly inflated and to avoid idling for extended periods of time.
