Honda Prologue vs Kia EV6: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Kia EV6 burns about $650 of fuel annually against $750 for the Honda Prologue. That $100 yearly gap compounds to roughly $500 over five years and $800 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 EV6 leads in both cycles — 136 mpg city and 103 mpg highway against 113 and 94 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Drivetrain and class: the Honda Prologue is offered with All-Wheel Drive, Front-Wheel Drive, the Kia EV6 with Rear-Wheel Drive, All-Wheel Drive. 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. The EPA classes them as Standard Sport Utility Vehicle 4WD and Small Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
