The New European Driving Cycle (NEDC) is a driving cycle designed to assess the emission levels of car engines and fuel economy in passenger cars (excluding light trucks and commercial vehicles). It is also referred to as MVEG cycle (Motor Vehicle Emissions Group).
The NEDC is supposed to represent the typical usage of a car in Europe. It consists of four repeated ECE-15 urban driving cycles (UDC) and one Extra-Urban driving cycle (EUDC).
The test procedure is defined in UNECE R101 and maintained by the UNECE World Forum for Harmonization of Vehicle Regulations (WP.29), which also works in its successor, the World Light Test Procedure (WLTP).
Although originally designed for petrol-based road vehicles, the driving cycle is now also used to estimate the electric power consumption and driving range of hybrid and battery electric vehicles.
