The Worldwide Harmonised Light vehicles Test Procedure (WLTP) [1] is a global driving cycle standard for determining the levels of pollutants, CO 2 emission standards and fuel consumption of conventional internal combustion engine (ICE) and hybrid automobiles, as well as the all-electric range of plug-in electric vehicles.
The following table compares official EPA ratings for fuel economy (in miles per gallon gasoline equivalent, mpg-e or MPGe, for plug-in electric vehicles) for series production all-electric passenger vehicles rated by the EPA for model years 2015, [1] 2016, [2] 2017, [3] and 2023 [4] versus the model year 2016 vehicles that were rated the most efficient by the EPA with plug-in hybrid ...
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)
Range matters mainly if you travel long distances, and it's only one factor on a long list that includes performance. Still, new EV shoppers worry about it. EV Highway Range Can Be Very Different ...
The Clean Air Act of 1963 (CAA) was passed as an extension of the Air Pollution Control Act of 1955, encouraging the federal government via the United States Public Health Service under the then-Department of Health, Education, and Welfare (HEW) to encourage research and development towards reducing pollution and working with states to establish their own emission reduction programs.
Turkey is planning to use the worldwide harmonized light vehicles test procedure (WLTP). [ 49 ] However, despite these tailpipe emission standards for new vehicle types there are many older diesel vehicles, [ 50 ] no low-emission zones and no national limit on PM2.5 particulates so local pollution, including from older vehicles, is still a ...
On the contrary, the current Worldwide harmonized Light vehicles Test Procedure (WLTP) strives to mimic real world driving behavior. The most common driving cycles are the WLTP, NEDC, SORDS and the FTP-75, the latter corresponding to urban driving conditions solely. Driving cycle design is the core technology for these standard cycles.
