What is the function of the regenerative braking system in the Kia Niro?

I'm considering purchasing a Kia Niro and I've heard about the regenerative braking system. Can you explain how it works and if it's worth the extra cost?

The regenerative braking system captures energy lost during braking and uses it to recharge the battery. It is a great feature for increasing fuel efficiency and reducing emissions.

I've found that the regenerative braking system is most useful in stop-and-go city driving. It helps extend the range of the electric motor and can save you money on gas.

In my experience, the regenerative braking system also helps improve the overall driving experience. It provides a smoother braking experience and can help with braking precision.
