Lucid Gravity vs Mercedes-Benz EQB: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Lucid Gravity burns about $700 of fuel annually against $700 for the Mercedes-Benz EQB. That $0 yearly gap compounds to roughly $0 over five years and $0 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 Gravity leads in both cycles — 115 mpg city and 106 mpg highway against 114 and 100 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Drivetrain and class: the Lucid Gravity is offered with All-Wheel Drive, the Mercedes-Benz EQB with Front-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 Standard Sport Utility Vehicle 4WD and Small Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
