What is the best fuel efficient Volkswagen Passat model?

I'm looking for the most fuel efficient Volkswagen Passat model in the market. Can someone recommend a specific year or features that will help me save on gas? Thank you in advance!

In my experience, the 2015 Passat TDI has been the most fuel efficient with its diesel engine. It also has great features such as a built-in fuel economy monitor to help you save on gas.

I've heard that the 2019 Passat SE has great fuel efficiency with its turbocharged engine and automatic start-stop feature. Definitely worth considering.

If you're looking for a budget-friendly option, the 2016 Passat S has a decent fuel economy and is a good value for the price. Just make sure to keep up with regular maintenance and you should be good to go.
