Mazda CX-5 vs Kia Sportage: fuel economy and fuel cost

In model year 2026 the Kia Sportage is the cheaper of the two to fuel: about $1,540 a year for its lowest-cost configuration (Sportage Hybrid, 42 MPG combined), against $2,490 for the Mazda CX-5 (CX-5, 26 MPG combined). That is $950 a year, or $4,750 over five years.

Both are classed as Small SUVs by the EPA. 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.
