I have a Ford C-Max Energi plug-in hybrid and a Smart ED both of which are AC with regen. Regen on the Smart is more aggressive meaning you really can do one-foot driving. Once I got used to it I found I like it and, of course, you can still find that spot on the pedal that allows coasting. The

The AC vs DC debate will never end. That's probably a good thing. Still, I often think that it's not really AC vs DC, it's series motor vs almost everything else. Most motors have torque curves very different from ICEs, but the series motor especially so - enough that in some situation you f
