Which is the most fuel-efficient Toyota Prius model?

I am looking to buy a Toyota Prius and I want to get the best fuel efficiency possible. Which Prius model should I choose?

The Toyota Prius Eco model is the most fuel-efficient option, achieving up to 56 mpg in the city and 53 mpg on the highway.

In my experience, the Toyota Prius Prime has the best fuel efficiency, with its plug-in hybrid system allowing for up to 54 mpg combined. Plus, it's environmentally friendly!

If you want the most fuel-efficient Prius, go for the Toyota Prius Prime. It has a larger battery than the regular Prius, allowing for more electric-only driving and better fuel economy overall.
