WLTP is a new legally binding test procedure for all car manufacturers to determine figures for exhaust emissions and fuel consumption. By approximating the test conditions to those of the real world, WLTP will deliver more practically relevant values. One of the changes is a significantly longer test duration (30 instead of 20 minutes) as well as redefined, significantly higher test speeds.
To obtain a more precise determination of CO2 emissions, the new test procedure will include not only standard equipment options – as was previously the case – but also all special equipment options of a vehicle. This will produce within the communication two values for each type of vehicle: the lowest and highest possible standard consumption value according to the equipment options. In the case of a specific vehicle configuration, however, the individual standard value can be indicated directly.
Thanks to WLTP, you will be able to better assess a vehicle’s consumption and CO2 emissions in future. As these values will be measured more realistically than before, higher consumption and CO2 figures can be expected for vehicles with combustion engines. In the case of electric vehicles, the electric range will decrease.
BMW is already working on the transition to the new test procedure and is preparing its product portfolio step-by-step with new vehicles, new engine versions or technical revisions. This will enable complete WLTP conformity to be assured for the entire fleet of the BMW Group.
From September 2018, all automobile manufacturers throughout the EU as well as in Switzerland and Turkey will be legally obliged to produce only vehicles that have been tested in accordance with the WLTP procedure. The transition to WLTP within the markets will depend on the respective national legislation. However, by December 2020, all countries that adopt the EU legislation for the approval of vehicles must indicate WLTP values for all vehicles.
