How is the Audi e-Tron's regenerative braking system different from a traditional braking system?

I've heard that electric cars have a different braking system compared to traditional gas cars. Can someone explain specifically how the Audi e-Tron's regenerative braking system works and how it differs from a traditional braking system?

The Audi e-Tron's regenerative braking system uses the electric motor to slow down the car and capture energy that would typically be lost in traditional braking systems. This energy is then stored in the battery and can be used as a power source for the car.

Unlike traditional braking systems, the Audi e-Tron's regenerative braking system is able to recuperate up to 70% of the kinetic energy that is generated when braking, contributing to increased efficiency and range for the car.

To increase the regenerative braking effect, the e-Tron also has a 'coasting' function that allows the car to coast when the driver takes their foot off the accelerator pedal. This helps to slow down the car without the need for traditional braking.
