There is very little gas savings in these new hybrids. Sam (Oneof my hosts) drove a GMC truck down last week and got 17 miles to a gallon. IT had a 48 volt hybrid system in it. Batteries all behind the back seat.
One thing that was pretty cool is it had no starter on it. When you turned the key you could barely hear the motor turn on. And it would turn off at intersections. Pretty cool.
He got the bad mostly on the highway and that is not where you get the savings.
From everything I\'ve seen the amount they save isn\'t huge at all.
You can get great mileage out of a diesel powered car too.
Plus when you plug it in at night, where do you think it gets the power from? Unless you live in an area where they have a dam or wind power you are polluting the environment with the power company anyway.
