Fuel economy at a glance
These are the EPA's official ratings for the 2026 Polestar 4 Long Range Single Motor. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.
Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).
| Combined MPG | 95 MPG |
| City MPG | 100 MPG |
| Highway MPG | 90 MPG |
| Annual fuel cost | $800 |

How the 2026 Polestar 4 Long Range Single Motor compares
The 2026 Polestar 4 Long Range Single Motor returns 95 combined MPG. Cars in the Standard Sport Utility Vehicle 2WD class for the same model year average 46.7 MPG, which puts this car ahead of the class average by about 103%.
The most efficient car in the Standard Sport Utility Vehicle 2WD class for the 2026 model year is the Audi Q4 45 e-tron at 115 MPG. The bar chart below puts the Polestar 4 Long Range Single Motor alongside the class best and the class average so you can see the full picture.
For broader context, the average new car of the 2026 model year (across all classes) returns 45.5 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 2026 model year is on its own page.
Annual fuel cost across driving patterns
The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for electricity, which is $0.15/kilowatt-hour. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.
The table below scales the EPA's number to three common driving patterns. The combined MPGe and the reference electricity price stay constant, only the annual mileage changes. Charging at home rather than at a public DC fast charger usually lowers the real cost below the EPA's published figure.
| Driving pattern | Estimated annual fuel cost |
|---|---|
| Light driver, 7,500 miles per year | $400 |
| Average driver, 15,000 miles per year | $800 |
| Heavy driver, 25,000 miles per year | $1,333 |
Year-over-year MPG for the Polestar 4 Long Range Single Motor

Specifications
The 2026 Polestar 4 Long Range Single Motor is a fully electric vehicle. It is powered by 200 kw pmsm. The EPA rates its driving range at 310 miles.
Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.
