EPA to NEDC range converter
A EPA range figure is about 37 % lower than the same car's NEDC figure. Example: 400 km EPA is about 630 km NEDC.

Formula: NEDC range = EPA range × 1.575. The winter estimate assumes about 25 % less than the converted figure.
What are EPA and NEDC?
EPA
EPA is the US standard. It applies an extra correction to the lab result, which makes it the most conservative of the four and the closest to what drivers see in mixed real-world use.
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.
Frequently asked questions
How do I convert EPA to NEDC?
Multiply the EPA figure by 1.575. For example, 400 km EPA × 1.575 = 630 km NEDC. 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.
