What is the best Ford Focus engine for fuel efficiency?

I am in the market for a new Ford Focus and I want to make sure I am getting the most bang for my buck in terms of fuel efficiency. Which engine option would you recommend for the best fuel efficiency in the Ford Focus?

Personally, I have found that the 1.0L EcoBoost engine in the Ford Focus offers the best fuel efficiency. It may be small in size, but it packs a punch and can save you a lot of money on gas.

I would recommend going for the 1.5L EcoBoost engine in the Ford Focus. It may not be as small as the 1.0L, but it still offers great fuel efficiency and has a bit more power.

I have the 2.0L engine in my Ford Focus and I have been very happy with its fuel efficiency. It may not be as impressive as the smaller engines, but it still gets the job done and has a good amount of power.
