The New European Driving Cycle (NEDC) was a driving cycle, last updated in 1997, designed to assess the emission levels of car engines and fuel economy in passenger cars (which excludes light trucks and commercial vehicles). It is also referred to as MVEG cycle (Motor Vehicle Emissions Group).
Test road (e.g. city, highway, etc.) measured data are the inputs to the 'Drive Cycle' preparation activity. The procedure involves instrumentation of the test vehicle to collect information while driving on the test road. There are two major types of data to be collected, Driver Behavior data and Vehicle versus Road data.
The "city" driving program of the EPA Federal Test Procedure is identical to the UDDS plus the first 505 seconds of an additional UDDS cycle. [5] [6] EPA FTP-75 driving cycle. Then the characteristics of the cycle are: Distance travelled: 11.04 miles (17.77 km) Duration: 1874 seconds; Average speed: 21.2 mph (34.1 km/h)
It aims to replace the previous and regional New European Driving Cycle (NEDC) as the new European vehicle homologation procedure. Its final version was released in 2015. One of the main goals of the WLTP is to better match the laboratory estimates of fuel consumption and emissions with the measures of an on-road driving condition. [4]
The China Light-Duty Vehicle Test Cycle (CLTC) (Chinese: 中国轻型汽车行驶工况; pinyin: Zhōngguó qīngxíng qìchē xíngshǐ gōng kuàng) is a driving cycle standard introduced by the government of China to measure the energy consumption, driving range and emissions of light-duty vehicles, including both internal combustion engine (ICE) vehicles and electric vehicles (EV).

Since the Euro 3 regulations in 2000, performance has been measured using the New European Driving Cycle test (NEDC; also known as MVEG-B), with a "cold start" procedure that eliminates the use of a 40-second engine warm-up period found in the ECE+EUDC test cycle (also known as MVEG-A).
