WLTP replaced the NEDC measuring procedure. New test parameters target more realistic values. See below how the procedures differ: |
---|
Conditions | NEDC |
WLTP |
---|---|---|
Test duration | 20 min. | 30 min. |
Test distance | 11 km | 23.5 km |
Time spent stationary | 25% | 13% |
Test phases | Urban/Extra-urban, (combined) | Low, Medium, High, Extra high, (Combined); (plus "City" for electric vehicles and vehicles with plug-in hybrid drivetrain |
Speed | Average: 34 km/h; Maximum 120 km/h | Average: 46.6 km/h ; Maximum 131 km/h |
Temperature | 20-30⁰ C Cold engine start | 14⁰C (tested at 23⁰ C corrected for 14⁰ C) Cold engine start |
Special equipment options | Not taken into consideration | All equipment options are considered in terms of their influence on aerodynamics, weight and rolling resistance. |
