What is the most efficient engine option for the Ford S-Max?

I am considering purchasing a new Ford S-Max and I want to make sure I get the best engine for optimal performance and fuel efficiency. Can anyone provide insight on the available engine options and which one would be the best choice?

Based on my personal experience, I highly recommend the 2.0L EcoBoost engine. It provides excellent power and fuel efficiency.

I would suggest looking at the 2.0L diesel engine. It offers great fuel economy and is also fairly powerful.

If you're looking for a more budget-friendly option, the 1.5L EcoBoost engine is a solid choice. It may not be as strong as the larger engines, but it still offers good performance.
