I really enjoy riding around town in Sport mode, it really makes a difference to me. I always use full regeneration at the same time which is easy because it stays locked in that state in Sport Mode. It obviously depends on how "hard" you drive the car but driving what I consider "normally" I have notice no significant difference in EV use compared to using Normal mode when I use full regeneration only occasionally when I remember. Has anyone else done this comparison? If it is true, it seems like a more fun way to drive.
