BMW iX vs Honda Prologue: what the numbers mean
Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Honda Prologue burns about $750 of fuel annually against $800 for the BMW iX. That $50 yearly gap compounds to roughly $250 over five years and $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 Honda Prologue leads in both cycles — 113 mpg city and 94 mpg highway against 99 and 94 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.
Drivetrain and class: the BMW iX is offered with All-Wheel Drive, the Honda Prologue with All-Wheel Drive, Front-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 Standard Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
