The most fuel efficient option for the Audi A4 is the 2.0-liter turbocharged four-cylinder engine, with an EPA rating of 27 mpg in the city and 36 mpg on the highway.

If you want even better fuel efficiency, consider the A4 Ultra engine which boasts an EPA rating of 31 mpg in the city and 42 mpg on the highway.
