Hyundai Kona 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 $600 for the Hyundai Kona. 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 Toyota bZ leads in both cycles — 144 mpg city and 119 mpg highway against 134 and 108 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Hyundai Kona is recorded with 4 distinct engine configurations (2.0, SIDI, with Stop-Start), the Toyota bZ with no. Across 58 recorded Hyundai Kona configurations and 8 for the Toyota bZ, the wider the engine spread the more the real-world fuel efficiency depends on which version you actually buy, so check the specific model year and drivetrain rather than the headline number.

Drivetrain and class: the Hyundai Kona is offered with All-Wheel Drive, Front-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 Small Sport Utility Vehicle 2WD and Small Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
