What is WLTP?

How much fuel does a vehicle use? Audi can now answer this question much more precisely with the WLTP harmonized drive cycle because the new method for measuring fuel consumption and CO₂ emissions is closer to everyday driving behaviours. This new procedure will replace the current NEDC standard from September 2017.

The new WLTP standard ("Worldwide Harmonized Light-Duty Vehicles Test Procedure") was developed on the basis of driving data collected around the globe and covers driving situations from inner-city traffic to motorway travel. Unlike the NEDC, the WLTP is much more dynamic because it has significantly more acceleration and braking than its predecessor. In addition, the effects of custom equipment on the weight, aerodynamics, and electrical system consumption (quiescent current) are taken into account in the WLTP.
