As the WLTP takes each vehicle’s particular equipment specification into consideration, its results are more accurate than under NEDC; they are, as it were, vehicle-specific. This alters nothing in terms of previous everyday fuel consumption. From September 2017, a new procedure for consumption and emissions tests is being introduced in the automotive industry; all newly certified vehicle models will be tested under WLTP. At the same time, the NEDC consumption value will continue to be determined and shown as the only valid consumption value in promotional materials. Between now and September 2018, Mercedes-Benz will gradually certify its portfolio under WLTP. From that date, it is likely that the new WLTP values will be shown in all sales documents and other publications. The NEDC consumption will be shown for discontinued models.
