WLTP to CLTC range converter
A WLTP range figure is about 15 % lower than the same car's CLTC figure. Example: 400 km WLTP is about 472 km CLTC.

Formula: CLTC range = WLTP range × 1.180. The winter estimate assumes about 25 % less than the converted figure.
What are WLTP and CLTC?
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.
CLTC
CLTC is the Chinese test cycle. It is run at lower average speeds than WLTP, so the same car shows roughly 15–20 % more range. Chinese brands launching in Europe usually publish a WLTP value later; that is the one to compare.
Frequently asked questions
How do I convert WLTP to CLTC?
Multiply the WLTP figure by 1.180. For example, 400 km WLTP × 1.180 = 472 km CLTC. 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.
