Why is the Audi e-Tron's range lower than other electric cars?

I've been doing some research on different electric cars and I noticed that the range for the Audi e-Tron is typically lower than other models. What makes the e-Tron's range lower and are there any ways to improve it?

The Audi e-Tron's lower range can be attributed to its larger and heavier size compared to other electric cars. This means it requires more energy to move and therefore has a lower range.
