The Honda Prologue is rated 102.3 MPGe (111 city, 93 highway) — that is not petrol economy but the distance it covers on 33.7 kWh, the energy held in one gallon. Drawn from a socket it needs 32.9 kWh per 100 miles, so 12,000 miles a year costs about $671 at $0.17 a kWh. The EPA's own annual figure for it is $750.
Every Honda Prologue version, compared
The Honda Prologue was rated in a single specification, so its consumption does not vary by version — only by model year. Yearly cost assumes 12,000 miles at $0.17 a kilowatt-hour.
| Version | Combined MPGe | City / Highway | Years | Charging per year |
|---|---|---|---|---|
| Electric | 111 / 93 | 2024–2026 | $671 |
What that actually costs
MPGe is an abstraction; the electricity bill is not. At 12,000 miles a year the Honda Prologue draws about 3948 kWh, which at $0.17 comes to the figures below.
| Measure | Value |
|---|---|
| Energy use | 32.9 kWh per 100 miles |
| Cost per mile | $0.056 |
| Charging per year | $671 |
| Charging over five years | $3,355 |
| Against other Electric cars | −$10 a year |
| EPA's own estimate | $750 a year |
City or highway — who is this car for
The Honda Prologue is one of the cars that does better in town than out of it — 111 in the city against 93 on the highway. That is $67 a year in favour of the commuter stuck in traffic, and it usually means a hybrid drivetrain recovering energy every time you brake.
| Measure | Value | Reading |
|---|---|---|
| City | 111 MPGe | $620 a year if you only drive in town |
| Highway | 93 MPGe | $738 a year if you mostly commute |
| Gap | -18 MPGe (-16%) | Reversed — it does better in town than on the open road |
How the Prologue changed over the years
The Prologue peaked in 2026 at 104 MPGe (113 city, 94 highway) and was at its thirstiest in 2024 at 99 — 5 MPGe apart, or $33 a year in fuel between buying one year and the other. The 2026 car does 104.
| Model year | Combined MPGe | City / Highway | Versions offered | Charging per year |
|---|---|---|---|---|
| 2026 | 113 / 94 | 1 | $661 | |
| 2025 | 113 / 94 | 1 | $661 | |
| 2024 | 107 / 91 | 1 | $694 |

How we count
This page rests on 3 EPA ratings of the Honda Prologue — 1 engine across 2024–2026. The mileage is EPA's laboratory figure, unchanged; the yearly bill is ours, at 12,000 miles and $0.17 a kilowatt-hour, against EPA's own estimate of $750. Full method.
Frequently asked questions
What is the Honda Prologue rated at?
102.3 MPGe combined on average — 111 in the city and 93 on the highway, per EPA ratings across 2024–2026. MPGe is distance covered on 33.7 kWh, the energy in a gallon of petrol — the car itself takes none.
How much does a Honda Prologue cost to charge per year?
About $671 at 12,000 miles and $0.17 a kilowatt-hour — roughly $3,355 over five years, or 0.056 dollars a mile.
Which Prologue version is the most efficient?
The Electric at 102.3 MPGe.
Is the Prologue efficient compared with similar cars?
Against other Electric cars it sits above the average of 101 MPGe, computed across 426 ratings.
Are these real-world Prologue figures?
No — they are EPA laboratory ratings, the same ones printed on the window sticker, and EPA's own annual fuel estimate for the Honda Prologue is $750 against the $671 we compute at 12,000 miles. Expect a little worse in practice: the spread between the city and highway figures is smaller than the spread between two drivers of the same one.
