How does the BMW i7's all-electric drivetrain work?

I am considering purchasing a BMW i7 and am intrigued by its all-electric drivetrain. How exactly does it work and what benefits does it offer?

The BMW i7's all-electric drivetrain utilizes a powerful electric motor to power the vehicle instead of a traditional combustion engine. This allows for a smoother and quieter driving experience, as well as zero emissions.

To better understand the i7's all-electric drivetrain, think of it as a large battery-powered remote-controlled car. The battery stores electricity, which powers the motor to move the car.
