Manufacturers advertise WLTP range as a single headline number. Drivers experience something messier: speed, temperature, elevation, and cabin climate control all move the needle.
What WLTP Actually Measures
WLTP is a standardized lab cycle. It is useful for comparing models under the same protocol, not for predicting your commute. Treat it as a relative benchmark, not a guarantee.
Where Real-World Range Diverges
- Highway speed — aerodynamic drag rises roughly with the square of speed; 130 km/h can cut range dramatically versus mixed urban use.
- Cold weather — chemistry slows and cabin heat draws from the pack unless you precondition on a charger.
- Load and hills — passengers, cargo, and sustained climbs increase energy use; regen helps on the way down but never fully recovers what you spent.
A Simple Planning Rule
For highway trips in mild weather, start with about 70–80% of WLTP. In winter highway conditions, plan closer to 60–70%, then adjust after a few tanks of experience in your own car.
How to Use Spec Sheets
On evstats.org, compare usable battery capacity, claimed consumption, and DC peak charge rate side by side. Range without charging context is only half the story for long trips.
