I had assumed that the 4 chevrons level of regen using the paddles is the maximum capable of the car. More recently, I've been paying more attention to the power meter (that crescent around the digital MPH indicator--blue portion shows power expended, green portion shows power regenerated). I noticed that 4 chevrons provides a modest level of regen (into the green portion) even at freeway speeds as I'm exiting. On the other hand, on other occasions when I'm braking more aggressively, I noticed that the level of regen level can be much greater than I've ever seen using the paddles. Does this mean that the car is capable of a very strong level of regen that can be activated using the brake pedal while the paddles provide only a fraction of that maximum even at 4 chevrons?
