What are the differences between the 2020 and 2021 Audi A4 models?

I'm looking to buy a new Audi A4 and was wondering which year's model (2020 or 2021) would be a better choice. What are the key differences between these two models and which one would you recommend?

The 2020 Audi A4 model features a 2.0-liter four-cylinder engine with 248 horsepower, while the 2021 model has a slightly more powerful 2.0-liter four-cylinder engine with 261 horsepower. In terms of performance, the 2021 model would be a better choice if power is your main consideration.
