Fiat 500e vs Nissan LEAF: what the numbers mean
Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Fiat 500e burns about $650 of fuel annually against $650 for the Nissan LEAF. 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 Nissan LEAF leads in both cycles — 131 mpg city and 111 mpg highway against 127 and 108 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.
Drivetrain and class: the Fiat 500e is offered with Front-Wheel Drive, the Nissan LEAF with 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 Minicompact Cars and Midsize Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
