What are some key features to look for when choosing an Audi e-Tron model?

I am planning to buy an Audi e-Tron, but I am not sure which model to choose from. What are some important features that I should consider before making my decision?

The most basic feature to look for is the battery capacity, for example, the Audi e-Tron 55 trim has a battery capacity of 95 kWh which offers a range of 222 miles. This is important to consider depending on your daily driving needs and the availability of charging stations in your area.
