Probably more work than the average buyer wants to go to, but we can say that with the reasonable default values in the model, electric cars are the least expensive. The point of the model, I think, is just as much to evaluate the result of changes to the default assumptions as finding the least expensive option. The types of vehicles included are: Conventional (ICE), Hybrid, Electric and Extended Range (Volt).
