Why does the Audi e-Tron's battery capacity affect its driving range?

I'm looking into purchasing an Audi e-Tron and noticed that its driving range varies depending on the battery capacity option. Can someone explain the relationship between battery capacity and driving range in electric vehicles?

The battery capacity directly impacts the available stored energy in an electric vehicle, which in turn affects the potential driving range of the vehicle. Simply put, a larger battery capacity allows for more energy storage and therefore a longer driving range.

In addition to battery capacity, other factors such as driving habits and external conditions (temperature, terrain, etc.) can also affect driving range. Make sure to consider all these factors when making your decision on battery capacity.

I highly recommend opting for a larger battery capacity if you have a longer daily commute or frequently take road trips. It may cost more upfront, but you'll appreciate the longer driving range in the long run.
