Obviously the battery pack has to be somewhat proportional to the vehicle size. So that would make an expensive Tahoe even way more expensive. At 2 bucks a gallon for gasoline, an unsubsidized electric vehicle is not a value proposition in my book.
Maybe picking up a cheap used one like this thread mentions would be economical for the kids to drive to high school or community college, or retirees who don’t travel much.
I was kidding.
I just got a new 2016 Tahoe, it is fantastic. I don’t drive very far, some days not at all, so I am not worried about the mileage. When I do take a road trip, the larger vehicle is what I want.
