Even though I wrote a post about it, I was still surprised to see this message. I managed to run the car around only on batteries for the entire month and probably hit the gas few only a couple miles the month before. So the Volt did the math and realized that the engine really needed to run for ten minutes to make sure the fuel in the lines didn’t turn into jelly.
I would like this to be the only time I heard the engine, when it felt the need to run because it hadn’t run in so long.
There are new batteries in development. In particular a Lithium Sulfer model that looks like it would quadruple the density of the current Lithium Ion units. That would be perfect for me.
