BMW i7 vs Fiat 500e: 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 $800 for the BMW i7. That $150 yearly gap compounds to roughly $750 over five years and $1,200 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 Fiat 500e leads in both cycles — 127 mpg city and 108 mpg highway against 91 and 95 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Drivetrain and class: the BMW i7 is offered with All-Wheel Drive, Rear-Wheel Drive, 4-Wheel Drive, the Fiat 500e 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 Large Cars and Minicompact Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
