If you go for either hybrid route, toyota or honda or brand X you can always get if not make a plug in kit for a few thousand. I have the enginer one and with the flip of a switch I get 10 mo mpg for 4 hours of use til it needs to be recharged. With a Toyota product you can use it in EV mode for a few miles, however its still limited in acceleration rate, speed, etc.
WIth the hybrid you can do both, drive cross country or ev only down the road and back. With an EV, you cant go cross country.
