Audi e-tron vs Polestar 3: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Polestar 3 burns about $800 of fuel annually against $950 for the Audi e-tron. That $150 yearly gap compounds to roughly $750 over five years and $1,200 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 Polestar 3 leads in both cycles — 105 mpg city and 89 mpg highway against 78 and 80 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Drivetrain and class: the Audi e-tron is offered with All-Wheel Drive, the Polestar 3 with Rear-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 Standard Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
