Why does the Audi A3 have a lower fuel efficiency than other models in its class?

I've been considering purchasing the Audi A3, but I noticed that it has a lower fuel efficiency compared to other models in the same class. Can anyone explain why this is the case?

The Audi A3 has a lower fuel efficiency due to its more powerful engine, which requires more fuel to operate. However, it should also be noted that the A3 has a larger fuel tank capacity, allowing for longer distances between refueling stops.

Audi prioritizes performance over fuel efficiency in the A3 model, using innovative technology such as direct injection and turbocharging to enhance engine power. This may result in a lower fuel efficiency compared to other models in its class.
