Fiat 500e vs Genesis G80: Specs Compared

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 $750 for the Genesis G80. 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 Fiat 500e leads in both cycles — 127 mpg city and 108 mpg highway against 105 and 93 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Fiat 500e is recorded with no distinct engine configurations, the Genesis G80 with 2 (SIDI & PFI, SIDI). Across 11 recorded Fiat 500e configurations and 43 for the Genesis G80, the wider the engine spread the more the real-world fuel efficiency depends on which version you actually buy, so check the specific model year and drivetrain rather than the headline number.

Drivetrain and class: the Fiat 500e is offered with Front-Wheel Drive, the Genesis G80 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 Large Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
