NEDC to WLTP range converter
A NEDC range figure is about 15 % higher than the same car's WLTP figure. Example: 400 km NEDC is about 348 km WLTP.

Formula: WLTP range = NEDC range × 0.870. The winter estimate assumes about 25 % less than the converted figure.
What are NEDC and WLTP?
NEDC
NEDC was the European standard until 2017. It uses a gentle laboratory cycle at low speeds, so its range figures are typically 15–25 % too optimistic compared with WLTP.
WLTP
WLTP is the European standard since 2017. It mixes urban, suburban and motorway driving at speeds up to 131 km/h and is the figure on EU price lists. It is a fair reference, though everyday range is usually 10–20 % lower.
Frequently asked questions
How do I convert NEDC to WLTP?
Multiply the NEDC figure by 0.870. For example, 400 km NEDC × 0.870 = 348 km WLTP. This is an average ratio: individual cars can differ by several percent.
Which figure is closest to real-world range?
EPA is the most conservative and usually the closest to mixed everyday driving. In winter, on the motorway or with a heavy load, expect a further 20–30 % less than any of these figures.
Why do the standards give different results?
Each standard uses a different test cycle: speeds, acceleration, temperature and how the lab result is adjusted differ. The car is the same; the yardstick is not.
