Why does the Audi e-Tron have a dual-motor system?

I have heard that the Audi e-Tron has a dual-motor system, but I'm not sure why. Can you explain the benefits and how it works?

The Audi e-Tron has a dual-motor system for improved performance and efficiency. By using two motors instead of one, the car can better distribute torque and power between the front and rear axles, resulting in better handling and traction. It also allows for smarter energy management, optimizing power usage and extending the range of the vehicle.

The dual-motor system in the Audi e-Tron also enables it to have an all-wheel drive capability, allowing it to handle various road conditions and terrain. This makes it a great option for those living in areas with rough weather or those who enjoy off-roading.
