What is the best Ford Galaxy engine for fuel efficiency?

I'm looking to purchase a Ford Galaxy, but I'm unsure which engine will give me the best fuel efficiency. Can anyone recommend the most efficient option?

I would recommend going with the 1.0L EcoBoost engine. It has great fuel efficiency and still provides enough power for a comfortable driving experience.

I have the 1.5L diesel engine in my Ford Galaxy and it has excellent fuel efficiency. I highly recommend it.
