Genesis G80 vs Mercedes-Benz EQE: what the numbers mean

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 Mercedes-Benz EQE. 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 Mercedes-Benz EQE pulls ahead on the interstate at 96 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 Genesis G80 is recorded with 2 distinct engine configurations (SIDI & PFI, SIDI), the Mercedes-Benz EQE with no. Across 43 recorded Genesis G80 configurations and 23 for the Mercedes-Benz EQE, 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 Genesis G80 is offered with All-Wheel Drive, Rear-Wheel Drive, the Mercedes-Benz EQE with Rear-Wheel Drive, All-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 Midsize Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
