My experience has been with both the iMiEV and LEAF. Each of these EV's have an Eco and a B drive mode which you can engage together or independantly. Frankly, I rarely used Eco. This setting, while I am sure it helped overall range a bit (as indicated by a few kilometer increase in the distance to empty when Eco was selected), left the accelorator feeling numb and severly reduced the vehicles performance. You could over ride it by punching the acelerator hard, but I would rather just drive gently in full power mode. However, I do use B most of the time. This setting maximizes the regenerative ability of the EV. Why would you not want this? It is free electricity and I will take that all day long as I drive. Which leads to the "regen game". All EV owners know about the regen game. You look for every opportunity while driving to regenerative brake and "add" kilometers to the distance to empty. Or at the very least, make the distance to empty number decline at a reduced pace vs the actual over the ground kilometers. Not only is the game fun to play, and contribute range to your EV, but I think it makes for a safer, more engaged driver. I revert to normal D on the highway and alwasy use cruise control when appropriate. Usually on the highway you maintain a steady spead and rarely slow down at all so regen is negligable. And the EVs cruise can do a better job of maintaining a steady speed than I can, thus saving more energy at highway speeds.
