Why is the Audi e-Tron's driving range shorter than other electric vehicles?

I've noticed that the Audi e-Tron's advertised driving range is significantly lower than other brands of electric vehicles. Can you explain why this might be?

The Audi e-Tron uses a larger and heavier battery compared to other electric vehicles, resulting in a shorter driving range. As such, it may not be as efficient for long distance trips as other brands.

One factor that contributes to the shorter range of the Audi e-Tron is its all-wheel-drive system, which requires more energy to operate. This results in a decrease in driving range compared to electric vehicles with a single motor and rear-wheel drive.
