Toyota Corolla vs Mazda3: fuel economy and fuel cost

In model year 2026 the Toyota Corolla is the cheaper of the two to fuel: about $1,310 a year for its lowest-cost configuration (Corolla Hybrid, 50 MPG combined), against $2,160 for the Mazda3 (Mazda3 4-Door, 30 MPG combined). That is $850 a year, or $4,250 over five years.

A frequently cross-shopped pair of rivals. 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.
