How does the Audi A2's regenerative braking work?

I've heard that the Audi A2 has a unique regenerative braking system, but I don't understand how it works. Can someone explain it to me in simple terms?

The Audi A2's regenerative braking system uses the car's kinetic energy to recharge the battery while braking, which increases the overall efficiency of the car.

When you press the brake pedal in the Audi A2, the system uses the motor to slow down the car instead of traditional friction brakes, which converts the car's kinetic energy into electrical energy to charge the battery.

The Audi A2's regenerative braking system is an advanced technology that helps to reduce energy consumption and emissions, making it a more environmentally friendly choice for driving.
