Audi SQ8 e-tron vs Tesla Model X: what the numbers mean
Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Tesla Model X burns about $700 of fuel annually against $1,050 for the Audi SQ8 e-tron. That $350 yearly gap compounds to roughly $1,750 over five years and $2,800 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 X leads in both cycles — 110 mpg city and 101 mpg highway against 72 and 75 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.
Drivetrain and class: the Audi SQ8 e-tron is offered with All-Wheel Drive, the Tesla Model X with 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 Standard Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
