How efficient is the regenerative braking system on the Audi e-Tron?

I've heard that electric vehicles have a regenerative braking system that helps with energy efficiency. Can you explain how the system works on the Audi e-Tron and how effective it is?

Hi David, the regenerative braking system on the Audi e-Tron works by capturing the kinetic energy produced during braking and converting it into electrical energy to be stored in the battery. This helps to extend the range of the vehicle and reduce the need for frequent charging. In my experience, the system is quite effective and can increase overall energy efficiency by up to 30%.
