Source snapshot 2026-10-05. Matching cohort: Minivan - 2WD · Regular Gasoline · Front-Wheel Drive · . All configurations in this shared cohort are included; other configurations on the source pages are excluded. This is a comparison of this cohort, not the entire nameplates or retail trims.
| Vehicle | EPA combined consumption | Cost / mile | 12,000 mi / year | 5 years / 60,000 mi |
|---|---|---|---|---|
| Toyota Sienna | 21–21 US MPG | $0.17 | $2,000.00 | $10,000.00 |
| Honda Odyssey | 22–22 US MPG | $0.16 | $1,909.09 | $9,545.45 |
How large is the energy-cost difference?
A minus B ranges from $90.91 to $90.91 per year, or $454.55 to $454.55 over five years. Positive means A costs more; negative means A costs less. If the range spans zero, the result depends on configuration. These bounds compare every included pairing, without declaring a winner from a best-case trim.
Method and limitations
Annual cost = miles ÷ combined US MPG × fuel price, or miles × kWh/100 mi ÷ 100 × electricity price. Regular/diesel $3.50/gal; premium $4.00/gal; electricity $0.17/kWh. Prices are illustrative, held fixed for five years, not current national averages. EPA wall-energy ratings include charging losses. EPA standardized ratings do not guarantee actual consumption. Costs exclude purchase price, financing, depreciation, insurance, maintenance, taxes and incentives.
