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

I am considering purchasing a Ford Mondeo but am unsure about which engine option is the most economical. I want to choose the option that will save me the most money on fuel in the long run. Can anyone provide some insight on which engine option I should go for?

I have a Ford Mondeo with the 1.0 Ecoboost engine and I am very happy with its fuel efficiency. It may not be the most powerful option, but it definitely saves me money on gas.

I have the 2.0 TDCi engine and while it may be more expensive upfront, it's worth it in the long run. It has great fuel efficiency and plenty of power when I need it.

I suggest going for the hybrid option if you're looking for the most fuel-efficient choice. I have the 2.0 Hybrid and it has saved me a lot on gas costs.
