The few I have looked up, is not a lot of difference. They save a lot by not having the engine, trans & gas tank. The difference between a gas Pacifica, and the hybrid version is about 500 lbs. They save a good bit by having a simple trans with the two electric motors built in.I guess the electric cars are significantly heavier causing more tire wear causing rubber pollution... what the heck. Can't win
Cars have so much safety stuff that weighs a lot. Plus just look how big our cars and trucks are now days. Heck, a half ton truck can do more then a lot of older 1 tons. No body makes a small or mid size pickup any more.
