How efficient is the Audi A1's fuel system?

I am considering purchasing an Audi A1 and I am curious about its fuel efficiency. Can anyone provide some insight or data on the fuel system of this car?

The Audi A1 has a highly efficient fuel system, with an average fuel economy of 6.3 L/100km in city driving and 4.5 L/100km on the highway.

I have been driving my A1 for over a year now and it has not disappointed in terms of fuel economy. On average, I only fill up once every two weeks.

In my experience, the A1's fuel efficiency greatly depends on how you drive it. If you have a heavy foot, you may see a decrease in fuel economy.
