WLTP stands for “Worldwide Harmonized Light Vehicles Test Procedure.” It is a globally standardized testing procedure for measuring the fuel consumption, CO2 emissions, and pollutant emissions from passenger cars and light commercial cars. The WLTP was developed to provide more accurate and reliable data on car emissions and fuel consumption compared to the previous New European Driving Cycle (NEDC) testing procedure.

The primary goals of WLTP include:

  1. Realistic Testing: The WLTP aims to provide more realistic and representative testing conditions that reflect modern driving behaviors and technologies. It takes into account various factors such as car acceleration, speed, braking, and different driving scenarios.
  2. Harmonization: The WLTP was developed to create a consistent and harmonized testing standard that can be used globally. This helps in comparing car performance and emissions across different regions and markets.
  3. Accuracy: The WLTP is designed to provide more accurate and reliable data on fuel consumption and emissions by using updated testing procedures and equipment.
  4. Adaptability: The WLTP is adaptable and can be updated as new technologies and car models are introduced, ensuring that it remains relevant and reflective of current car performance.

The transition from the NEDC to the WLTP has led to changes in how car emissions and fuel consumption are reported and regulated. The WLTP testing procedure generally produces higher values for CO2 emissions and fuel consumption compared to the NEDC. This has implications for car taxation, environmental regulations, and consumer information.

It’s important to note that the details and regulations related to car testing procedures can vary by region and country. The WLTP is an important step in providing more accurate information about car emissions and fuel consumption, contributing to better environmental awareness and regulatory decisions in the automotive industry.
