WESSEX GARAGES WORLDWIDE HARMONISED LIGHT VEHICLE TEST PROCEDURE


What is WLTP and how does it work?

Under EU law, the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) laboratory test measures fuel consumption and CO2 emissions from passenger vehicles, as well as their pollutant emissions.

What's the purpose of the tests?

  • TAXATION: Most EU countries apply CO2 tax based on vehicle emissions.
  • COMPARISON: Consumers wil have more transparency, allowing reliable CO2 emissions and fuel economy and fuel economy comparisons between vehicles.
  • CO2 TARGETS: Manufacturers must ensure new vehicle models don't emit more CO2 on average than targets set by the EU, which is 95kg/km CO2.
  • OFFICIAL DOCUMENTATION: Once a vehicle has passed the test, it will received official documents allowing it to be registered anywhere in Europe.

What are the benefits?

WLTP introduces much more realistic and strict testing conditions, including:

  • Driving situations, including urban, suburban, main roads, and motorways
  • Average and maximum speeds
  • Average and maximum driving power
  • Ambient temperatures
  • Best and worst-case values on consumer info
  • Accelerations and deceleration
  • Driving behaviour

In conclusion, WLTP provides a much more accurate calculation of a car's fuel consumption and emissions, which better reflects the on-road performance of the car you are purchasing.
