EV real-world range estimator for United Kingdom

WLTP is a lab number — this estimates how far you will actually get at your temperature, driving style and battery health

New batteries count as 100%. Most modern EVs lose only 1–2% a year and manufacturers keep a hidden buffer, so older cars often still report 90%+.

kWh / 100 km

Leave blank to use the model estimate. Your car’s long-term trip-computer average in kWh/100 km is the most accurate input — tyres, load and route all move it.

Why is real-world range lower than WLTP?

WLTP is a lab cycle at 23 °C with no air conditioning or heating and only brief higher-speed sections. It is great for comparing cars, but nobody actually drives like that.

Highway speed is the range killer: raising cruising speed from 100 to 120 km/h raises aerodynamic drag with the square of speed and can add 25–35% to consumption. Slow city driving usually beats the WLTP figure.

Cold hurts an EV far more than a petrol car: denser air adds drag and cabin heating draws real energy from the battery. Expect 15–20% off around freezing and 25–30% in a proper cold snap. Preconditioning the cabin while still plugged in recovers most of it.

Real-range questions

Why is my EV's real-world range lower than the WLTP figure?

WLTP is a lab test at 23 °C with no air conditioning, no heating and only brief higher-speed sections. Real driving adds cabin heating or cooling, hills, headwinds and sustained highway speeds — typically 10–25% less in mixed driving and 25–35% less on the open road.

How much does cold weather reduce EV range?

Around freezing, expect roughly 15–20% off your normal range; in a proper cold snap (−5 °C or colder) 25–30% is common. Preconditioning the cabin while still plugged in, and using seat/steering-wheel heating rather than cabin heat, recovers most of the loss.

What is a realistic EV range in {country}?

For a BYD Atto 3 at 14 °C in Mixed city + open road driving, the estimate is about 245 mi — roughly 94% of its 261 mi WLTP rating.

Does battery state of health matter?

Yes, but less than most people fear. Most modern EVs lose only 1–2% of capacity per year, and manufacturers build in a hidden buffer, so a five-year-old car typically reports 90–95% state of health. Some brands (Kia, Hyundai, BYD) show 100% for years because the buffer shrinks first.

Estimates combine manufacturer WLTP figures with published real-world patterns and are for guidance only. Route, wind, load, tyres and air conditioning all move the result — trust your trip computer.
