Re: Charging issues? Range?

You're assuming high (peak) power output equals inefficient non-peak use of energy.

That was very true for old carburetted internal combustion engines. It's a lot less true with the new breed of one-liter 160BHp units with computerized fuel injection and high boost turbo/superchargers. And it's almost completely untrue for electric motors and control systems.

Likewise, aggressive driving in a conventional car means wastefully dumping kinetic energy into heating up the brakes. Far less so with regenerative electrical braking. And in any case, responsible owners of high-power cars don't drive aggressively for more than a tiny fraction of the time. The efficiency penalty with a six-liter "muscle car" is mostly fuel wasted while cruising, with the engine running at a tiny fraction of its peak power output, using fuel very inefficiently.

The bottom line? These days you *can* have your cake and eat (most of) it.
