What is the most fuel efficient engine option for a Ford Focus?

I am looking to purchase a Ford Focus and want to make sure I get the best gas mileage possible. What engine option should I go for that will give me the highest fuel efficiency?

If fuel efficiency is a top priority for you, I would suggest going for the EcoBoost engine option. It delivers impressive fuel economy without sacrificing performance.

Based on my personal experience, the EcoBoost engine is definitely the way to go. It has excellent fuel efficiency and is also fun to drive.

I've owned both the EcoBoost and standard engine options for the Ford Focus and I can confidently say that the EcoBoost is worth the upgrade. It pays off in the long run with savings on gas.
