Why does the 2021 Audi A5 have 4 doors instead of 2 on the coupe version?

I've noticed that the previous models of Audi A5 had 2 doors, but the 2021 version has 4. What was the reason behind this change and how does it affect the performance of the car?

The main reason for the switch from 2 doors to 4 doors on the 2021 Audi A5 coupe is due to safety regulations. Having 4 doors allows for easier accessibility and faster evacuation in case of an emergency.
