Chevrolet Equinox vs Polestar 3: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Chevrolet Equinox burns about $700 of fuel annually against $800 for the Polestar 3. That $100 yearly gap compounds to roughly $500 over five years and $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 Chevrolet Equinox leads in both cycles — 117 mpg city and 100 mpg highway against 105 and 89 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Chevrolet Equinox is recorded with 3 distinct engine configurations (SIDI, 1.6, SIDI; FFV), the Polestar 3 with no. Across 57 recorded Chevrolet Equinox configurations and 12 for the Polestar 3, the wider the engine spread the more the real-world fuel efficiency depends on which version you actually buy, so check the specific model year and drivetrain rather than the headline number.

Drivetrain and class: the Chevrolet Equinox is offered with All-Wheel Drive, Front-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 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.
