Mercedes-Benz EQS vs Tesla Model S: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Tesla Model S burns about $600 of fuel annually against $700 for the Mercedes-Benz EQS. 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 Tesla Model S leads in both cycles — 132 mpg city and 116 mpg highway against 101 and 105 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Drivetrain and class: the Mercedes-Benz EQS is offered with All-Wheel Drive, Rear-Wheel Drive, the Tesla Model S 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.
