UNECE WP29 is currently developing a new global harmonized driving cycle, the World Light Test Procedure (WLTP) with participation of experts from the European Union, India, and Japan; it will apply to light duty vehicles (i.e. passenger cars and light commercial vans). [15]
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 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 Vehicle versus Road data are used to prepare the road drive cycle and the Driver Behavior data to prepare the Driver model.

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)
Start-stop technology was introduced in Europe first because of regulatory differences: 25 percent of the New European Driving Cycle (NEDC) is spent idling, [10] while only an estimated 11 percent of the United States Environmental Protection Agency (EPA) test is spent idling. Start-stop activation depends on specific driver inputs as well as ...
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).
The World Motorcycle Test Cycle (WMTC) is a system of driving cycles used to measure fuel consumption and emissions in motorcycles. The methods are stipulated as part of the Global Technical Regulation established under the United Nations ’ World Forum for Harmonisation of Vehicle Regulations , also known as WP.29.
