Subaru Solterra vs Tesla Model X: what the numbers mean
Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Subaru Solterra burns about $650 of fuel annually against $700 for the Tesla Model X. 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 Subaru Solterra leads in both cycles — 131 mpg city and 109 mpg highway against 110 and 101 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.
Drivetrain and class: the Subaru Solterra 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 Small 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.
