CLTC to WLTP range converter
A CLTC range figure is about 18 % higher than the same car's WLTP figure. Example: 400 km CLTC is about 339 km WLTP.

Formula: WLTP range = CLTC range × 0.847. The winter estimate assumes about 25 % less than the converted figure.
What are CLTC and WLTP?
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.
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 CLTC to WLTP?
Multiply the CLTC figure by 0.847. For example, 400 km CLTC × 0.847 = 339 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.
