Why does the Audi A7 have a bigger engine than the A5?

I was looking at the Audi A7 and noticed that it has a bigger engine than the A5. Is there a reason for this difference and how does it affect performance and fuel efficiency?

The Audi A7 has a larger engine size because it is a more high-performance model compared to the A5. This allows for more power and faster acceleration, but it may come at the cost of higher fuel consumption.

A bigger engine size in the Audi A7 means more power and torque, which can enhance driving experience. However, it also results in lower fuel efficiency and higher emissions.

The difference in engine size between the Audi A7 and A5 can also be attributed to different market demands and target demographics. The A7 caters to those seeking a more powerful and luxurious driving experience.
