The Prologue is Honda's midsize electric SUV at roughly 3 mi/kWh, matched against gas crossovers and SUVs near 24–27 mpg. On home charging the per-mile cost falls well below gasoline, and because family SUVs rack up miles, the annual fuel savings add up faster than on a low-mileage commuter.
It's a mainstream-priced EV, so the premium to recover is reasonable. As always, the more you charge at home rather than on public DC, the better the numbers look.
What to keep in mind
- Family-size with a clearly lower per-mile cost than a ~26 mpg gas SUV.
- High family mileage maximizes the annual savings.
- Public DC charging narrows the gap versus charging at home.
Honda Prologue: common questions
How much does it cost to charge a Honda Prologue?
At the U.S. average home electricity price of about 17¢/kWh and roughly 3 mi/kWh, a Honda Prologue costs about 6¢ per mile to charge at home — around $680 a year at 12,000 miles. Public DC fast-charging costs more, so set your home/public mix in the calculator.
Is a Honda Prologue cheaper to run than a gas car?
Charging at home, usually yes. Against a typical 26-mpg gas crossover, the Honda Prologue's per-mile fuel cost is much lower — the calculator shows your annual fuel saving and how long the price difference takes to pay back.
