What Audi models have the best fuel efficiency?

I'm looking to purchase an Audi, but I want to make sure it's fuel efficient. Can you recommend any models that have the best fuel efficiency?

Based on my personal experience with Audis, I would recommend the A3 sedan or the Q5 SUV for their excellent fuel efficiency. They both have efficient engines and advanced technology that helps with fuel management.

I've done some research and found that the Audi A6 and A7 have great fuel efficiency ratings. They also have a hybrid option for even better gas mileage.

I've owned multiple Audis and can confidently say that the A4 is one of the most fuel efficient models. It also has some great features like start-stop technology to save even more fuel.
