Range is the headline figure buyers care about most, and it is the product of two things: usable battery capacity and efficiency — how far the car travels per kWh. Official figures come from standardised tests (WLTP in Europe, EPA in the US), with EPA generally the more realistic. Real-world range varies widely with speed, temperature, terrain, payload and use of heating or air conditioning; motorway cruising and hard winters can cut it by 20–30% below the rated figure. Modern mainstream EVs typically offer 250–500 km, with long-range models exceeding 600 km. Because charging adds range back in minutes on a trip, usable range matters most for daily driving rather than absolute maximum.
- Distance on a full charge; depends on capacity and efficiency
- Official figures use WLTP (Europe) or EPA (US, more realistic)
- Cut 20–30% by motorway speed and cold weather
- Mainstream EVs now offer roughly 250–600 km
