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]
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 ...
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 ...
In the 1980s, the old NEDC as European homologation lab-bench procedure was established to simulate urban driving condition of a passenger car. [12] In 1988, in the EEC, Directive 88/76/EEC, change law to rules more stringent than ECE Regulation 15/04. [11]
Vehicle type approval is the confirmation that production samples of a design will meet specified performance standards. [4] Traditionally, there are two systems of type approval in Europe. The first one is based on the EC directives and regulates the approval of whole vehicles, vehicle systems, and separate 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.
In the European Union, emissions of nitrogen oxides (NO x), total hydrocarbon (THC), non-methane hydrocarbons (NMHC), carbon monoxide (CO) and particulate matter (PM) are regulated for most vehicle types, including cars, trucks (lorries), locomotives, tractors and similar machinery, barges, but excluding seagoing ships and aeroplanes.
