What does the 'eDrive' function do in the BMW i5?

I've noticed a button labeled 'eDrive' in my BMW i5. Can someone explain what this does and how it affects the car's performance?

The 'eDrive' function in the BMW i5 allows you to switch between different modes of electric driving. When activated, it prioritizes using electricity rather than gas, optimizing fuel efficiency and reducing emissions.

Using the 'eDrive' function can also increase the car's acceleration and overall performance, as the electric motor provides instant torque.

I recommend using the 'eDrive' function for short trips or in congested city areas where electric power can be fully utilized. This will help extend the battery life and save you money on gas.
