Fiat 500e vs Tesla Model 3: what the numbers mean
Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Tesla Model 3 burns about $550 of fuel annually against $650 for the Fiat 500e. That $100 yearly gap compounds to roughly $500 over five years and $800 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 3 leads in both cycles — 150 mpg city and 133 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 Tesla Model 3 with All-Wheel Drive, Rear-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.
