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 versus highway split: the Toyota bZ4X is the stronger commuter at 131 mpg city, while the Subaru Solterra pulls ahead on the interstate at 109 mpg highway. If most of your driving is stop-and-go traffic the city figure is the one to weigh; for long-distance highway mileage the reverse is true, and the two vehicles effectively swap places depending on how you 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.
