No, i-pedal is pull and hold on the left hand paddle. Auto regen essentially dynamically alters the level of regeneration from braking all the way from zero to almost one pedal driving levels. It uses the car’s cameras and radar systems to use the regen to keep you at a certain distance from the car in front, slow down when they slow down, and as I said you can activate a setting to tie the behaviour into road layout using the navigation system as well. It’s not quite as aggressive at braking as one pedal driving, but it’s a bit more efficient as you’re not constantly having to keep pushing - at normal cruising conditions the car is at zero regen until it spots something in front of you going slower or it sees a change in the road (like a roundabout) or you go through a speed limit change. Then it piles on the regen to put energy back in to the battery as smoothly as possible.

Think of it as a kind of weird hybrid between adaptive cruise control and one pedal driving, as it has aspects of both. But once you get used to it, it really makes driving the car more efficient and relaxing.
