WLTP: Worldwide Harmonized Light Vehicle Test Procedure
The new consumption and emissions test method
Having come into force for passenger cars on 1st September 2017, WLTP ensures greater transparency providing test results that are closer to real world operation. This new testing procedure will also be applicable to all Light Commercial Vehicles (LCV)’s from 31st August 2019.
Using a more dynamic driving profile based on real driving data and on-road performance, WLTP means higher measured values for customers and consequently a more realistic benchmark for consumption and emission figures.
Due to advances in technology and the evolution of driving conditions, its predecessor NEDC (New European Driving Cycle), was considered outdated. Developed in the 1980s and based on theoretical driving, NEDC no longer provides the most accurate representation of real consumption figures.
Going forward, WLTP will not only provide more accurate consumption and emissions testing but also enables pollutant, C02 emissions and fuel consumption values to be comparable worldwide.
The future of WLTP can also enable customers to determine their CO2 levels more accurately.
