What is SC03?

Supplemental Federal Test Procedure SC03 (SC03) is a laboratory driving-cycle / range-label used primarily in United States. ExploreCalcTools documents SC03 so buyers can compare estimated EV range figures across standards such as WLTP, EPA, NEDC and CLTC.

SC03 does not measure the same mix of speed, temperature, HVAC load, or stop-and-go behaviour as every other cycle. A car rated SC03 500 km will often show a different number under EPA or CLTC — our converters apply empirical estimate factors only.

Manufacturers still publish ratings under this label in many markets; treat brochure figures as lab conditions, not guaranteed road range.

Practical tips

  • Prefer comparing the same vehicle under the same standard when possible.
  • Cold weather, highway speed, and cabin heating typically reduce real-world range vs lab figures.
  • Legacy cycles (NEDC, JC08, 10-15, China NEDC) often look optimistic versus modern WLTP/EPA.

Educational estimates only — not a substitute for manufacturer or regulatory ratings.

EV range standards use different testing procedures and conditions. Conversions between standards are estimates and are not exact mathematical conversions. Actual real-world range may vary based on vehicle model, battery size, speed, temperature, terrain, driving style, HVAC use, and other conditions.
