Cadillac LYRIQ 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 Cadillac LYRIQ.

City and highway economy: the Honda Prologue leads in both cycles — 113 mpg city and 94 mpg highway against 100 and 83 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Drivetrain and class: the Cadillac LYRIQ is offered with All-Wheel Drive, Rear-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 Small 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.
