Two vehicles, one set of assumptions
Pick up to four exact EPA configurations. All get the same mileage, driving mix, and energy prices — so the difference you see is the vehicles, not the assumptions. Gasoline and electricity are always priced separately; MPGe is never treated as MPG.

2026 Volkswagen ID.4: EPA electricity consumption is measured from the wall outlet, so typical home AC charging losses are already included. Public DC fast-charging prices, extreme temperatures, and driving style can change real-world cost.
