The Hummer EV is the heaviest, least efficient electric vehicle here at roughly 1.5 mi/kWh. That sounds damning until you remember what it's up against: gas trucks and SUVs in its size and power class struggle to hit 14–16 mpg. Even at that low efficiency, home charging usually still beats gasoline on cost per mile.
The real obstacle isn't the electricity — it's the price. Fuel savings take a long time to repay a sticker near $100,000, so this is a comparison where the break-even matters more than the per-mile number. Add both prices in the calculator to see how long it really takes.
What to keep in mind
- Lowest efficiency here (~1.5 mi/kWh) — home charging does all the heavy lifting.
- It replaces very thirsty ~14 mpg gas trucks, so per-mile savings are still real.
- A ~$98,000 sticker means a long payback — check the break-even, not just the fuel.
