Which Audi A3 model is best for fuel efficiency?

I am looking to purchase an Audi A3, but I want to prioritize fuel efficiency. Which specific model would be the most fuel efficient and why?

The Audi A3 e-tron is the most fuel efficient model in the A3 lineup with an EPA-estimated 83 MPGe combined rating. This is due to its hybrid powertrain which combines a 1.4-liter turbocharged four-cylinder engine with an electric motor.

You may also want to consider the Audi A3 TDI model which achieves an impressive EPA-estimated 35 mpg combined, thanks to its efficient diesel engine. However, keep in mind that diesel fuel can be more expensive in some areas.

If you prioritize fuel efficiency but still want a sportier driving experience, I would recommend the Audi A3 Sportback e-tron. It has the same hybrid powertrain as the e-tron, but also features a sportier design and suspension.
