What's the difference between NEDC and WLTP?
Since the introduction of NEDC in 1992, cars and driving styles have changed quite a bit. The WLTP test parameters have been redefined to reflect real conditions more closely. They now include:
- Longer cycle times (30 min v. 20 min)
- Shorter stopping times (13% v. 25%)
- Longer distances (about 23 km/14 miles v. 11 km/6 miles)
- Higher speeds (maximum 130 km/h or 80 mph vs 120 km/h or 75 mph)
- Almost 50% higher average speeds
- Higher maximum acceleration and more acceleration phases
- Approximately 20-30% higher driving power, based on the more dynamic driving situations
- More realistic calculation of driving resistance for fuel consumption tests
- Consideration of optional equipment in the vehicle
The values obtained with WLTP are comparable worldwide, while the NEDC values are only valid in Europe.
