What are the key differences between the 2019 and 2020 Audi A3 models?

I've been considering purchasing an Audi A3 and I noticed that there was a 2019 and 2020 model. I'm not sure if there are any significant changes between the two. Can someone provide some clarification?

The 2019 and 2020 models have some notable differences. The 2020 model has updated exterior styling and a more modern interior design. It also has a new infotainment system with better functionality. The 2019 model, on the other hand, has a more powerful engine option. Depending on your priorities, one may be a better fit for you.
