  • US EPA and Department of Energy fuel economy data (fueleconomy.gov), file dated Nov 4, 2026.
  • EPA fuel price assumptions: regular $4.00, midgrade $4.61, premium $5.01, diesel $6.13 a gallon; electricity $0.15 per kWh. The yearly cost is EPA's estimate for 15,000 miles, 55% of them in the city; a plug-in hybrid's assumes EPA's typical mix of charging and gas.
