Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Kia Sportage burns about $1,450 of fuel annually against $2,000 for the Buick Encore. That $550 yearly gap compounds to roughly $2,750 over five years and $4,400 over eight — often more than the price difference between two trims of the same vehicle, and the single largest running-cost line item separating these two.

City and highway economy: the Kia Sportage leads in both cycles — 42 mpg city and 44 mpg highway against 30 and 33 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

All-wheel drive typically costs one to two mpg combined against the same vehicle in front- or rear-wheel drive, which is worth remembering when the gap between these two is small.
