What is the difference between Audi A1 model year 2020 and 2021?

I am interested in buying an Audi A1, but I am unsure about which model year to choose. Can someone explain the differences between the 2020 and 2021 models and give me some tips on which one to pick?

The major difference between the Audi A1 2020 and 2021 models is the exterior design. The 2021 model has a more sporty and modern look, with a larger grille and sleeker lines. In terms of performance, both models are quite similar, but the 2021 model has slightly better fuel efficiency.
