What is quattro regenerative braking in the Audi e-tron?

I've heard that the Audi e-tron has quattro regenerative braking. What does that mean and how does it work?

Quattro regenerative braking is a technology in the Audi e-tron that allows for energy to be captured and reused while braking. It works by converting the kinetic energy of the vehicle into electricity, which is then stored in the battery.

Quattro regenerative braking is a unique feature in the Audi e-tron that helps improve energy efficiency. By using the electric motor to slow down the vehicle and capture energy, it reduces the strain on the brakes and helps to maximize the range of the vehicle.
