Which model year of the Toyota Camry offers the best fuel efficiency?

I am considering purchasing a Toyota Camry and I want to make sure I get the most fuel efficient model. Can someone tell me which model year offers the best fuel efficiency?

In my personal experience, the 2018 Toyota Camry has the best fuel efficiency compared to other models.

I've been a proud owner of a 2017 Toyota Camry for years now and it has amazing fuel efficiency. I highly recommend it.

I work at a Toyota dealership and from what I've seen, the 2020 Camry has the best fuel efficiency out of all the model years.
