Honda Civic vs Tesla Model 3: fuel economy and fuel cost
In model year 2026 the Tesla Model 3 is the cheaper of the two to fuel: about $670 a year for its lowest-cost configuration (Model 3 Standard, 139 MPGe combined), against $1,330 for the Honda Civic (Civic 4Dr, 49 MPG combined). That is $660 a year, or $3,300 over five years.
One of the two is electric-only; the other has no electric configuration in this model year. Costs assume 15,000 miles a year and the same fuel and electricity prices for both vehicles, using the EPA combined rating (55% city, 45% highway). Each figure is rounded to $10 and every difference is calculated from the rounded values.
The EPA is still publishing model year 2027 ratings, so this page compares model year 2026, the latest complete year.

Frequently asked questions
Which is cheaper to fuel, the Honda Civic or the Tesla Model 3?
The Tesla Model 3 is cheaper: about $670 a year against $1,330 for the Honda Civic, a difference of $660 a year. That compares the lowest-cost configuration of each in model year 2026 at 15,000 miles a year with the same fuel prices.
How much would the Tesla Model 3 save over five years?
About $3,300 ($660 a year for five years), assuming 15,000 miles a year and the same fuel prices. Your total depends on how much you drive and on local prices; see fuel cost by state.
Can MPG and MPGe be compared?
The Tesla Model 3 is rated 139 MPGe and the Honda Civic 49 MPG. MPGe is the EPA's way of expressing electric efficiency per 33.7 kWh, the energy in a gallon of gasoline. It is a different measure from gasoline MPG, so annual fuel cost ($670 vs $1,330) is the better yardstick.
How is the annual fuel cost calculated?
Distance of 15,000 miles a year at the EPA combined rating (55% city, 45% highway). Gasoline is priced at $4.36/gal (EIA U.S. average for regular, Sep 2026) and electricity at 18.3¢/kWh (EIA U.S. residential average, Jul 2026); premium and diesel configurations use their own EIA prices. Each result is rounded to $10, and differences are calculated from the rounded figures.
Are the Honda Civic and the Tesla Model 3 in the same class?
Yes. The EPA classes both as Midsize cars.
