WLTPmittaukset

WLTPmittaukset, also known as WLTP measurements, refer to standardized testing procedures used to determine the fuel consumption, CO2 emissions, and electric range of vehicles. WLTP stands for Worldwide Harmonized Light Vehicles Test Procedure, an international protocol designed to provide more realistic and comparable data across different vehicle types and markets. It was developed by the United Nations Economic Commission for Europe (UNECE) to address limitations of previous testing methods, such as the NEDC (New European Driving Cycle), which often resulted in overly optimistic estimates.

The WLTP protocol involves a series of laboratory tests that simulate real-world driving conditions, including urban, suburban, and highway driving cycles. The testing accounts for factors like acceleration, braking, and varying speeds, aiming to reflect typical vehicle usage more accurately. Results from WLTP testing are used for labeling vehicles, informing consumers, and guiding regulatory standards on emissions and fuel efficiency.

Implementing WLTP improves transparency by providing consumers with data that better mirrors everyday driving experiences. Manufacturers are required to specify WLTP-based fuel consumption and emissions figures for their vehicles, which are then displayed on vehicle labels and documents. Since its adoption in the European Union in 2017 for new car certifications and subsequently in other markets, WLTP has become a key element in the effort to reduce environmental impacts from vehicle transportation.

Overall, WLTPmittaukset represent a significant step toward more accurate and meaningful vehicle performance measurements, supporting policies aimed at sustainable mobility and environmental protection.
