Kia EV9 vs Toyota bZ: what the numbers mean
Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Toyota bZ burns about $550 of fuel annually against $850 for the Kia EV9. That $300 yearly gap compounds to roughly $1,500 over five years and $2,400 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 Toyota bZ leads in both cycles — 144 mpg city and 119 mpg highway against 101 and 78 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.
Drivetrain and class: the Kia EV9 is offered with Rear-Wheel Drive, All-Wheel Drive, the Toyota bZ 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 Small Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
