Pollutant emissions of combustion engines

From 1^er September 2017, new vehicle models in Europe will be tested on the WLTC cycle rather than the NEDC cycle. This measure will be extended to all new vehicles from 1^er September 2018.

The WLTP procedure leads to much more realistic test conditions with :

• much more realistic driving (e.g., gear shifts are no longer imposed);

• a greater variety of driving conditions (urban, suburban, main road, freeway);

• longer test distance and duration (NEDC = 11km in 20min, WLTC = 23.25km in 30min);

• more realistic ambient temperatures, closer to the European average ( NEDC: 20°C ≤T≤30°C; WLTC: T= 23°C and CO₂ values are corrected for T=14°C)...
