Real range vs EPA / WLTP: how far does your EV actually go?
Rated range — EPA in the US, WLTP elsewhere — is measured in mild, gentle conditions, so real driving almost never matches it. Pick your car, then set the temperature, how you drive, climate use and battery health to estimate your real-world range. Every value is editable.

How to read the result
We start from the rated range and apply a multiplier for each condition: temperature (cold costs the most, because the battery is less efficient and the cabin needs heating), how you drive (highway speeds use far more energy than city driving, where regenerative braking helps), climate-control load, and battery health, which shrinks the usable capacity as the car ages. The breakdown shows roughly how many miles each factor adds or removes.
Frequently asked questions
- Why is real range lower than the rating?
- EPA testing uses mild temperatures, gentle acceleration and limited high-speed cruising. Real driving — cold mornings, fast highways, the heater on — uses more energy, so 70–85% of the rated number is typical.
- Why does cold weather hit range so hard?
- Two reasons: a cold battery is chemically less efficient, and heating the cabin draws a lot of power directly from the battery rather than from waste engine heat. Preconditioning while plugged in and using seat heating instead of cabin heat both help.
- Why does highway driving use more than city?
- Air resistance rises with the square of speed, so steady fast cruising is the worst case for an EV. In the city, low speeds and regenerative braking recover energy, so EVs are often most efficient there — the opposite of a gas car.
- Where do the figures come from?
- The vehicle list uses approximate manufacturer range and usable battery; the derate factors are seeded from published cold-weather range studies. They're sensible defaults, not a promise for a specific car — edit any value to match yours.
