How does the engine size affect the performance of Audi sedans?

I'm looking at different Audi sedan models and I noticed that they have different engine sizes. I'm wondering how this affects their performance and what are the pros and cons of bigger or smaller engines?

The engine size definitely plays a crucial role in the performance of Audi sedans. The bigger the engine, the more power it can produce which leads to quicker acceleration and higher top speed. However, bigger engines also consume more fuel and may be heavier, impacting fuel efficiency and handling.
