The Polestar 4 is rated 92.5 MPGe (96.5 city, 88.5 highway) — that is not petrol economy but the distance it covers on 33.7 kWh, the energy held in one gallon. Drawn from a socket it needs 36.4 kWh per 100 miles, so 12,000 miles a year costs about $743 at $0.17 a kWh. The EPA's own annual figure for it is $825.
Every Polestar 4 version, compared
The Polestar 4 was rated in a single specification, so its consumption does not vary by version — only by model year. Yearly cost assumes 12,000 miles at $0.17 a kilowatt-hour.
| Version | Combined MPGe | City / Highway | Years | Charging per year |
|---|---|---|---|---|
| Electric | 96.5 / 88.5 | 2025–2026 | $743 |
What that actually costs
MPGe is an abstraction; the electricity bill is not. At 12,000 miles a year the Polestar 4 draws about 4368 kWh, which at $0.17 comes to the figures below.
| Measure | Value |
|---|---|
| Energy use | 36.4 kWh per 100 miles |
| Cost per mile | $0.062 |
| Charging per year | $743 |
| Charging over five years | $3,715 |
| Against other Electric cars | +$62 a year |
| EPA's own estimate | $825 a year |
City or highway — who is this car for
The Polestar 4 is one of the cars that does better in town than out of it — 96.5 in the city against 88.5 on the highway. That is $36 a year in favour of the commuter stuck in traffic, and it usually means a hybrid drivetrain recovering energy every time you brake.
| Measure | Value | Reading |
|---|---|---|
| City | 96.5 MPGe | $712 a year if you only drive in town |
| Highway | 88.5 MPGe | $777 a year if you mostly commute |
| Gap | -8 MPGe (-8%) | Reversed — it does better in town than on the open road |
How the 4 changed over the years
The 4 peaked in 2026 at 95 MPGe (100 city, 90 highway) and was at its thirstiest in 2025 at 90 — 5 MPGe apart, or $39 a year in fuel between buying one year and the other. The 2026 car does 95.
| Model year | Combined MPGe | City / Highway | Versions offered | Charging per year |
|---|---|---|---|---|
| 2026 | 100 / 90 | 1 | $724 | |
| 2025 | 93 / 87 | 1 | $763 |

How we count
This page rests on 2 EPA ratings of the Polestar 4 — 1 engine across 2025–2026. The mileage is EPA's laboratory figure, unchanged; the yearly bill is ours, at 12,000 miles and $0.17 a kilowatt-hour, against EPA's own estimate of $825. Full method.
Frequently asked questions
What is the Polestar 4 rated at?
92.5 MPGe combined on average — 96.5 in the city and 88.5 on the highway, per EPA ratings across 2025–2026. MPGe is distance covered on 33.7 kWh, the energy in a gallon of petrol — the car itself takes none.
How much does a Polestar 4 cost to charge per year?
About $743 at 12,000 miles and $0.17 a kilowatt-hour — roughly $3,715 over five years, or 0.062 dollars a mile.
Which 4 version is the most efficient?
The Electric at 92.5 MPGe.
Is the 4 efficient compared with similar cars?
Against other Electric cars it sits below the average of 101 MPGe, computed across 426 ratings.
Are these real-world 4 figures?
No — they are EPA laboratory ratings, the same ones printed on the window sticker, and EPA's own annual fuel estimate for the Polestar 4 is $825 against the $743 we compute at 12,000 miles. Expect a little worse in practice: the spread between the city and highway figures is smaller than the spread between two drivers of the same one.
