I'm just working from what I'm reading. The wiki entry listed below states:

"A weakness [of a series hybrid] is that the power from the combustion
engine has to run through both the generator and electric motor. During
long-distance highway driving, the electrical transmission can be less
efficient than a conventional transmission."

That's not the impression I got from my reading. I do understand that once
the car gets up to crusing speed, it's primarily driven by the gas engine.
However, the low speed startup seems to be completely electric. This is
different than other cars like the Insight, which can't move at all without
the gas engine running.

The average driver wants a lot from their car. Gas is a compact, powerful,
cheap fuel. So I understand why hybrids are constructed the way they are.

The wikipedia entry on hybrid drivetrains sheds quite a bit of light:

You and I are thinking in different directions. I seek a true electric with
gas/diesel as a backup. The Standard Prius mixes and matches. But it does
have the facility to drive the car totally electric. If it has a plugin,
then you only need the gas engine in an emergency.
