I-WLTP umjikelezo wokuhlola omusha othatha indawo ye-NEDC, ebisetshenziswa, cishe ingashintshiwe, iminyaka engama-20. Igama lezinga (noma umjikelezo wokuhlola) obeka ingxenye yemboni yezimoto onqenqemeni lokuphazamiseka kwemizwa. Imikhiqizo eminingi isimemezele ukumiswa kwesikhashana kokukhiqizwa kwamanye amamodeli abo, futhi ikakhulukazi, kwezinye izinjini, ukuze kubhekwane nokuguqukela emjikelezweni omusha wokuhlola we-WLTP, ukuze emva kokungenelela okudingekayo, ziphinde zihlolwe. futhi yaqinisekiswa kabusha.
Njengoba sesike sabika, imiphumela izwakala kuyo yonke imboni, ngesimemezelo sokuphela kwezinjini eziningana, ukumiswa okwesikhashana kokukhiqizwa kwabanye - ikakhulukazi uphethiloli, lapho izihlungi zezinhlayiya zizongezwa khona, kakade kulungiselelwa i-Euro evamile. I-6d-TEMP kanye ne-RDE — kanye nokwehliswa/ukwenziwa lula kwezinhlanganisela ezingaba khona — izinjini, ukuhanjiswa kanye nemishini — kuhlu lwamamodeli.
Isikhathi esidingekayo ukuze kungenelele amamodeli nokwenza izivivinyo zesitifiketi kungase kusho ukuthi amamodeli athile, manje athengiswayo, awatholakali uma i-WLTP iqala ukusebenza, ngomhla ka-1 kuSepthemba.
Ngemuva kokuthi i-Porsche imemezele amakhefu esikhashana kwezinye izinhlobo zayo ekupheleni kwesonto eledlule, “isisulu” sakamuva IPeugeot 308 GTI - uhlobo lwaseFrance lumemezele ukuthi imodeli ngeke isakhiqizwa ngoJuni nango-Okthoba kulo nyaka. I-1.6 THP ye-270 hp izothola isihlungi sezinhlayiyana, kodwa uhlobo lwesiFulentshi luthembisa ukuthi i-270 hp ye-hatch eshisayo izohlala ngemva kokungenelela.
