Which Audi A5 model offers the best fuel efficiency?

I am considering purchasing an Audi A5 for my daily commute and I want to make sure I am getting the most fuel-efficient option. Which A5 model should I choose?

Based on EPA ratings, the Audi A5 Sportback with a 45 TFSI engine offers the best fuel efficiency with an estimated 27 mpg in the city and 37 mpg on the highway.

I highly recommend opting for the A5 Coupe with a 40 TFSI engine for its impressive 23 mpg in the city and 30 mpg on the highway.

If fuel efficiency is your top priority, I suggest looking into the A5 Cabriolet with a 40 TFSI engine, which boasts an estimated 24 mpg in the city and 30 mpg on the highway.
