What is the most fuel-efficient Ford car model?

I am interested in purchasing a Ford S-Max and I am looking for the most fuel-efficient option. Which model should I consider and what type of fuel should I use?

In my opinion, the Ford S-Max Hybrid is your best bet for a fuel-efficient option. It combines a gasoline engine with an electric motor and can get up to 35 miles per gallon in the city.

You should also consider using premium fuel for better efficiency and performance. It may cost a bit more, but it will ultimately save you money in the long run.
