What is the best Audi model for fuel efficiency?

I am looking for a fuel-efficient car and considering buying an Audi. What Audi model would you recommend for the best fuel efficiency?

The Audi A3 is a great option for fuel efficiency. It has a 1.4-litre TFSI engine that can achieve up to 46.3 mpg in combined driving. In addition, its lightweight construction and aerodynamic design contribute to its efficient performance.

I would suggest looking into the Audi A4. It is equipped with a 2.0-litre TFSI engine that can achieve up to 45.6 mpg in combined driving. Its start-stop system also helps save fuel by automatically turning off the engine when idling.

If you want the best fuel efficiency from an Audi, the A5 Sportback is the way to go. It has a 2.0-litre TDI engine that can achieve up to 55.4 mpg in combined driving. Its lightweight construction and improved aerodynamics also contribute to its efficiency.
