BMW i4 vs Mercedes-Benz EQS: what the numbers mean
Running cost over five years: at the EPA's 15,000-mile-a-year assumption the BMW i4 burns about $650 of fuel annually against $700 for the Mercedes-Benz EQS. 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 and highway economy: the BMW i4 leads in both cycles — 122 mpg city and 119 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 BMW i4 is offered with All-Wheel Drive, Rear-Wheel Drive, 4-Wheel Drive, the Mercedes-Benz EQS 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 Subcompact Cars and Large Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
