BMW i7 vs Genesis G80: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Genesis G80 burns about $750 of fuel annually against $800 for the BMW i7. That $50 yearly gap compounds to roughly $250 over five years and $400 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 Genesis G80 is the stronger commuter at 105 mpg city, while the BMW i7 pulls ahead on the interstate at 95 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.

Powertrain choice: the BMW i7 is recorded with no distinct engine configurations, the Genesis G80 with 2 (SIDI & PFI, SIDI). Across 34 recorded BMW i7 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 BMW i7 is offered with All-Wheel Drive, Rear-Wheel Drive, 4-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 Large Cars and Large Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
