EV range, decoded: CLTC vs WLTP vs EPA vs NEDC

The range on the spec sheet depends entirely on which test it came from — and most are optimistic. Enter any badge number, pick its standard, and see what it means everywhere else, including on a real road.

Your conditions

A CLTC rating of 500 km is really about 326 km in everyday driving.

CLTC (China)500 km
NEDC (old EU)470 km
WLTP (EU / global)422 km
EPA (US)370 km
Real-world (typical)326 km
Real-world (your conditions)326 km

What each standard means

CLTCChina

China's cycle. Low average speed, no sustained high-speed phase — the most optimistic of the four. Treat a CLTC badge as a best-case number.

NEDCEurope (old)

The old European lab cycle, phased out around 2017-19. Gentle and unrealistic; still quoted in some markets. Very optimistic.

WLTPEurope / global

The newer global lab cycle that replaced NEDC. More dynamic and realistic, but still run in a lab — typically a bit higher than you'll see on the road.

EPAUnited States

The US standard. Multi-cycle, includes highway and climate adjustments — the closest of the lab standards to real driving.

Conversions use typical multipliers (CLTC ≈ EPA×1.35, NEDC ×1.27, WLTP ×1.14). Real cars vary — treat these as honest estimates, not guarantees.
