BMW i4 vs Polestar 2: 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 $650 for the Polestar 2. 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 2 is the stronger commuter at 124 mpg city, while the BMW i4 pulls ahead on the interstate at 119 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 BMW i4 is offered with All-Wheel Drive, Rear-Wheel Drive, 4-Wheel Drive, the Polestar 2 with All-Wheel Drive, Rear-Wheel Drive, Front-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 Midsize Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
