ACEA: what is WLTP and when will the changes take place?Back

Currently, cars are tested under a lab test called the New European Driving Cycle (NEDC) which was designed in the 1980s. Due to evolutions in technology and driving conditions, this test is now outdated. The European Union has therefore designed a new test – the Worldwide Harmonised Light Vehicle Test Procedure (WLTP).

Differently from the old NEDC test, the WLTP cycle was developed using real-driving data. Although the WLTP test was intended to be used as a global test cycle across different world regions, ‘the European Union and other regions will apply the test in different ways depending on their road traffic laws and need’, the ACEA says.

The new WLTP test will officially apply to new cars introduced in the market for the first time from September 2017 and to all new car registrations from September 2018.

Tests such as the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) are used to measure fuel consumption and CO2 emissions from passenger cars, as well as their pollutant emissions.
