WLTP: The Next Generation Vehicle Emission Testing and Data Standard

WLTP (Worldwide Harmonized Light Vehicles Test Procedure) is an international standard developed to more accurately measure vehicle emissions and fuel consumption. This next-generation testing procedure allows vehicles to be tested under conditions closer to real-world usage, resulting in more reliable and comparable data.

 

What is WLTP?

WLTP is a test procedure used to measure vehicle emissions and fuel consumption. This standard aims to test vehicles under conditions closer to real-world usage, thereby obtaining more accurate and reliable results.

 

When Did WLTP Come Into Effect?

WLTP officially came into effect in the European Union on September 1, 2018. It has been implemented in other countries around similar dates. Since then, the emissions and fuel consumption of new vehicles have been measured using the WLTP test.

 

How Are WLTP Data Obtained?

The WLTP test involves testing vehicles under various driving scenarios in a laboratory setting at a standardized speed and altitude. During these tests, vehicle emissions and fuel consumption are measured and recorded according to standard WLTP procedures.

 

What Are WLTP Standards?

WLTP test procedures are designed to test vehicles at different speeds, loads, and driving conditions. These standards aim to test vehicles under conditions closer to real-world usage, resulting in more reliable and comparable data.

 

How Are WLTP Data Displayed?

WLTP test results are typically found in vehicle brochures or sales materials. These data show important performance characteristics of the vehicle, such as emissions and fuel consumption. Additionally, WLTP data can be used to assess and compare the environmental impact of vehicles.

 

WLTP represents a significant advancement in vehicle emission testing and data standardization. This next-generation testing procedure helps reduce environmental impacts and provides consumers with better information by enabling more accurate and reliable data collection.
