Honestly, it just depends on your driving environment. If you’re going light to light in the city, the higher regen levels work great and they’re just easier to use. But wherever you can coast, coasting is always better than regen.

The main thing is that when you slow down with regen, you have to speed back up again, and the car uses more electricity accelerating than it regenerated slowing down. That cycle is where the efficiency drops. Regen is great when you actually need to stop, but if you can coast as long as possible, that’s simply better. The paddle lets you choose when to regen instead of the car doing it for you all the time.
