What are the main differences between the 2019 and 2020 Audi A4 models?

I am considering purchasing an Audi A4, but I am not sure if I should go for the 2019 or 2020 model. Can someone explain the main differences between the two models in terms of features, performance, and price?

The main difference between the 2019 and 2020 Audi A4 models is the newly updated infotainment system in the 2020 model, which runs faster and includes more advanced features. In terms of performance, the 2020 model offers a more responsive and refined driving experience. However, this comes at a slightly higher price point compared to the 2019 model.
