Why does the 2021 Audi A4 have a reduced fuel efficiency compared to previous models?

I noticed that the 2021 Audi A4 has a lower fuel efficiency rating than previous versions. Is there a specific reason for this change?

The 2021 Audi A4 has a lower fuel efficiency due to the addition of more advanced technology features, such as a larger touchscreen display and upgraded entertainment system. These features require more power and ultimately impact the fuel efficiency.

The 2021 Audi A4 also has a more aerodynamic design, which enhances its overall performance but can also result in a lower fuel efficiency. However, the trade-off is a smoother and more enjoyable driving experience.
