Polestar EV Range Calculator

Verified baseline references

These are model-year 2026 US EPA records, including their wheel and Performance Pack labels. Polestar’s current model-family pages can cover updated configurations, so a current headline is not automatically the rating of a 2026 vehicle. The 2026 Polestar 3 single-motor records here are 286 miles with 20-inch wheels and 291 with 21-inch wheels. Both values are preserved as certified records; no universal wheel-size deduction is inferred.

Polestar: expected range is a changing estimate

The 2026 Polestar 4 manual describes instrument-panel range as a prediction using current and historical driving and real-time conditions. After delivery or a factory reset, it begins from a certified value and then learns the driving history. A change in that estimate alone does not establish a change in battery capacity.

This calculator’s published preset stays fixed to its EPA record. Its owner baseline is a separate measurement of distance per charge used. The dashboard prediction, the published rating and a trip measurement are therefore three different observations. Compare them only after recording the departure charge and conditions; do not treat their difference as an automatic battery-health percentage.

Wheel and Performance Pack records

The 2026 Polestar 3 Long Range Dual Motor entries are 312 miles with 21-inch wheels and 281 with 22-inch wheels; the Performance Pack also has a 281-mile record. Polestar 4 Long Range Dual Motor is 280 miles, while its Performance configuration is 255. Those figures describe named test configurations. Applying an additional generic performance or wheel penalty after choosing the matching record would count an effect twice.

The single-motor Polestar 3 entries demonstrate why this planner does not apply a blanket rule that each larger wheel reduces range by a fixed amount. Select the exact recorded configuration and verify the vehicle label. If you have changed tires or equipment since delivery, calibrate from comparable trips instead of assuming the original rating still describes the modified car.

Prepare the charging stops, not just the distance

The Polestar 4 long-trip guidance recommends enough charge for the first leg, checking charging locations and downloading maps when connectivity may be poor. Enter the distance to the usable stop, including its access road. Choose a reserve that leaves room for an alternative stop; a positive calculated margin does not establish that the destination charger is available.

The reserve cost of a Performance configuration

For Polestar 4 Long Range Dual Motor, 80% departure and 10% reserve give 196.0 miles from the 280-mile EPA baseline. The 255-mile Performance record gives 178.5 miles. On a 170-mile leg at factor 100%, the respective estimated arrival charges are 19.3% and 13.3%. The comparison changes only the selected certified configuration; it adds no separate performance penalty.

Calculation method and owner calibration

Usable distance = baseline × conditions factor ÷ 100 × (starting charge − reserve) ÷ 100

Arrival charge = starting charge − leg distance ÷ (baseline × conditions factor ÷ 100) × 100

The method assumes distance scales approximately with the charge used. It does not model changing speed, wind, elevation, traffic, parked energy use, battery temperature or auxiliary loads. The conditions factor is an explicit assumption; no automatic age, temperature or equipment coefficient is applied.

To estimate an owner baseline, divide the distance of a representative journey by the fraction of charge used, with no recharge between readings. For example, 75 miles using 30 percentage points gives approximately 250 miles as a full-charge equivalent. Repeat with several comparable journeys. Use factor 100% when your measured baseline already describes the planned conditions, so the same effects are not counted twice.

A positive margin only means the arithmetic reaches your chosen reserve under these assumptions. A negative margin means the chosen distance exceeds that charge budget. Confirm route and charging conditions with the vehicle’s guidance; this tool does not diagnose the battery.
