Genesis G80 vs Lucid Air: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Lucid Air burns about $500 of fuel annually against $750 for the Genesis G80. That $250 yearly gap compounds to roughly $1,250 over five years and $2,000 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 Lucid Air leads in both cycles — 149 mpg city and 142 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 Genesis G80 is recorded with 2 distinct engine configurations (SIDI & PFI, SIDI), the Lucid Air with no. Across 43 recorded Genesis G80 configurations and 41 for the Lucid Air, 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 Lucid Air 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.
