Polestar 3 vs Volvo EX90: 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 $800 for the Volvo EX90. That $0 yearly gap compounds to roughly $0 over five years and $0 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 versus highway split: the Polestar 3 is the stronger commuter at 105 mpg city, while the Volvo EX90 pulls ahead on the interstate at 91 mpg highway. If most of your driving is stop-and-go traffic the city figure is the one to weigh; for long-distance highway mileage the reverse is true, and the two vehicles effectively swap places depending on how you drive.
Drivetrain and class: the Polestar 3 is offered with Rear-Wheel Drive, All-Wheel Drive, the Volvo EX90 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 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.
