Can I trust the WLTP figure when buying?

Use it to compare models, but expect 10–30% lower real-world range depending on season and driving pattern.

Why does the winter score matter?

EV Advisor's winter score reflects how well a model retains range in cold weather, which the WLTP figure does not.

WLTP vs. real-world range: what's the difference?

Why an EV's stated range rarely matches real-world driving, and what actually affects it.

What is WLTP?

WLTP (Worldwide Harmonised Light Vehicle Test Procedure) is a standardised lab test that makes range figures comparable between models, but it doesn't account for cold weather, speed, or driving style.

What affects real-world range the most?

Cold weather, high motorway speeds, climate control, and heavy loads reduce range the most. In Norwegian winters, 15–30% lower range than the WLTP figure is normal.
