WLTP

Worldwide harmonised Light-duty vehicle Test Procedure.

 

A better way to measure fuel consumption.

What is WLTP?

WLTP stands for Worldwide Harmonised Light-Duty Vehicles Test Procedure and is a new testing method to estimate a vehicle’s emissions and fuel consumption. This procedure is based on real recorded driving data. It will help to simulate realistic driving even under laboratory conditions. That is why WLTP not only takes into consideration various situations and speeds but also a vehicle’s different equipment variants and weight classes.

Why WLTP?

WLTP revises consumption values.

The previous standard New European Driving Cycle (NEDC) was introduced in 1992 and is now outdated and does not accurately represent the individual, day-to-day driving behaviour. In contrast, the new WLTP standard aims to ensure that the consumption values measured during a model’s type approval testing are more realistic. The aim is to ensure that test conditions better reflect real-world driving, so CO2 emissions and/or fuel consumption figures for vehicles may increase compared to those NEDC figures that are available now.

NEDC vs WLTP

What will change?

In Autumn 2017, WLTP replaced the NEDC measuring procedure. New testing parameters ensure more realistic values. The new testing procedure has a modified driving cycle and stricter test specifications. These include a longer time span for the measurement along with a higher maximum speed.
