WLTPtestikava

The WLTP testikava, or Worldwide Harmonised Light Vehicle Test Procedure, is a standardized method for measuring the fuel consumption, energy consumption, and CO₂ emissions of passenger cars and light commercial vehicles. Introduced to replace the older New European Driving Cycle (NEDC) test, WLTP was developed to provide more realistic and comparable results under various driving conditions.

WLTP was adopted as part of the European Union’s regulatory framework in 2017, with mandatory implementation for new vehicle type approvals beginning in 2018. The test simulates real-world driving scenarios more accurately by incorporating a wider range of speeds, accelerations, and driving modes, including urban, rural, and highway conditions. It also accounts for different vehicle configurations, such as battery electric vehicles and hybrid systems, ensuring broader applicability.

The test consists of four driving cycles representing various conditions, with each cycle lasting between 30 and 60 minutes. These cycles include cold and hot starts, as well as different vehicle loads and altitudes. The results are expressed in liters per 100 kilometers (L/100km) for fuel consumption and grams per kilometer (g/km) for CO₂ emissions, providing a more transparent and consistent comparison between vehicles.

WLTP has been widely adopted beyond the EU, with many countries and regions, including the United States, Japan, and China, incorporating it into their testing standards. Critics argue that while WLTP is an improvement over NEDC, it still does not fully replicate real-world driving variability. However, it remains a key tool in regulating vehicle emissions and improving fuel efficiency standards globally.
