Tesla Model Y vs Toyota bZ: what the numbers mean
Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Tesla Model Y burns about $550 of fuel annually against $550 for the Toyota bZ. That $0 yearly gap compounds to roughly $0 over five years and $0 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 Tesla Model Y leads in both cycles — 148 mpg city and 129 mpg highway against 144 and 119 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.
Drivetrain and class: the Tesla Model Y is offered with All-Wheel Drive, Rear-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 4WD and Small Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
