Motor vehicle type approval is the method by which motor vehicles, vehicle trailers and systems, components and separate technical units intended for such vehicles achieve type approval in the European Union (EU) or in other UN-ECE member states. There is no EU approval body: authorized approval bodies of member states are responsible for type ...
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 grey market reached 66,900 vehicles imported by individual consumers in 1985, and altered to meet U.S. design regulations. [15] It is no longer possible to import a vehicle into the United States as a personal import, with four exceptions, none of which permits Americans to buy recent vehicles not officially available in the United States.

The European Commission intends to introduce a type approval procedure to measure the energy efficiency of mobile air conditioning systems in vehicles, as well as its effect on fuel consumption and emissions, and display an efficiency label on the vehicle; the work is being performed by TU Graz (Institute for Internal combustion engines and ...
This directive aims at the clarification of the type approval procedure for motor vehicles, separate technical units (i.e., trailers), and components. It simplifies the documentation, designates the type approval number of a separate technical unit by a certificate of conformity, and defines the vehicles, individual technical units, and components.
The first steps toward harmonizing vehicle regulations internationally were made in 1952 when WP.29, a working party of experts on vehicles' technical requirements, was created. This resulted in the 1958 Agreement on uniform conditions of approval and mutual recognition of vehicle approvals, components, and parts.
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 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).
