What is the fuel economy of the Audi A6 in comparison to its competitors?

I am considering purchasing an Audi A6 and I am curious about its fuel efficiency. How does it compare to other luxury sedans in its class?

According to EPA estimates, the 2021 Audi A6 gets an average of 28 miles per gallon (mpg) on the highway and 22 mpg in the city.

Compared to its competitors, such as the BMW 5 Series and Mercedes-Benz E-Class, the Audi A6 has a slightly better fuel economy on the highway and city.

To improve fuel efficiency, consider opting for the Audi A6 with a hybrid powertrain.
