I was invited to Busch Gardens last weekend to see their lighted decorations for this time of year. Being short notice I took the Insight out for a spin and was smiling the whole way. I did not have the phev kit on as I did not know the current state of charge as it was unplugged and the bms was turned off. On the way home I got 2 mpg less. Notice the mini p&g I am doing going up and down a few mph, Notice the slight regen, thats what you will see going over 75 mph, just a slight regen, but you cant feel it.
