That's right Charles. Remember, that is pure electric range. You don't use any gasoline. For myself, that would work well. There are many days where I drive less than 20 miles. On those days I would not have to use any gasoline. On the other hand, if I had to go somewhere further, the gasoline engine would just kick in. I also assume that like a regular hybrid, the system would "harvest" energy (breaking, for example) while driving in hybrid mode. This is not a Nissan Leaf or Tesla system.
Seems strange that it took this long to add a built-in battery charger to a hybrid. This finally seems like a real starting point for electric cars, all problems solved. No gasoline for short everyday trips, but not having to buy another car when road trips come up. Standard hybrids were a small gain in efficiency due to all the power still deriving from gasoline.
I just hope they got the sticker price right as well, make it affordable so that the extra cost ROI is less than 5 years.
The all electric range is a little short, but the total range is quite good. I guess the next question is the cost of ownership. It seems that the pricetag has been pretty hefty these days, and 20 miles is just a little short to keep the cost down. I also wonder of the 20 miles is with all the lights, heat, wipers and everything off, so as soon as it's cold and raining at night the range drops to 5 miles.
