The U.S. Environmental Protection Agency has further explored annual fuel costs of cars by powertrain type in a newly released study.

Using 15,000 miles (24,000 km) as a typical comparison mileage (55% city / 45% highway), plug-in vehicles are simply unbeatable.  The total fuel costrange for plug-in vehicles in America break down like this:

  • BEVs vary from $500 to $800/year
  • PHEVs vary from $550 to $1,850/year

It's especially important to underline that this is one of the scenarios that savings are proportional to the driving distance and style of the EV owner...so there can be a lot of flex in the numbers.

The estimated annual fuel costs for model year (MY) 2017 all-electric vehicles is the lowest of all the different fuel types, ranging from a low of $500 to a high of $800 per year.

The annual fuel costs for plug-in hybrid electric vehicles (PHEV) are heavily influenced by the electric range of the vehicle.

In hybrid electric vehicles (HEV), the technology is used not only for maximizing fuel economy, as in the Hyundai Ioniq Blue with fuel costs of $600, but also for boosting performance, as in the Ferrari LaFerrari Aperta with fuel costs of $3,250. Conventional gasoline vehicles for MY 2017 have estimated annual fuel costs of $900 to $3,850 – the widest range, but also the category with the most vehicle models available.

Note: Fuel cost assumptions were:

  • Vehicle driven 15,000 miles per year
  • 55% city driving, 45% highway driving
  • $2.33 per gallon for regular unleaded gasoline, $2.82 per gallon for premium, $2.57 per gallon for diesel, and $0.13 per kilowatt-hour for electricity.
  • PHEV fuel cost estimates are based on blended gasoline/electricity costs.
