Since the 1980's we have been used to having our emissions and fuel economy tested using the New European Driving Cycle (NEDC) but now times have changed. Please welcome, WLTP...
The European Union developed the Worldwide Harmonized Light Vehicles Test procedure (WLTP) to give both car buyers and owners a more realistic understanding of a car's performance, coming into effect on 1st September 2017.
Working in conjunction with WLTP will be an emissions test that also measures pollutants directly on the road - Real Driving Emissions (RDE) - which has been brought in to provide a closer representation of 'real world' fuel consumption and provide model specific values at the point of sale. This takes place on real roads, the RDE test compliments lab tests by measuring that a car delivers low pollutant emissions on the road.
"Everyday tests, realistic results"
Toyota, in particular, are a car manufacturer that has welcomed the change to WLT, as it follows their strong values in clean mobility. WLTP helps the movement driven by Toyota, towards a low carbon society, after the company spending decades researching how to make vehicles kinder to the environment and introducing hybrid technology.
Due to the advances in vehicle technology and changes in driving conditions, the nearly 40 year old NEDC driving cycle test is no longer as accurate. As a result, governments have decided to replace the previous method of fuel consumption and emissions testing with a much more reliable procedure. Changes introduced by WLTP will include:
Test Cycle
Dynamic tests which are more representative of real-driving behaviour
Cycle Distance
23.25 kilometres long, over twice the old distance
Average & Maximum Speeds
Average speed is 46.5km/h (an increase of 12.5km/h) while top speed is raised to 131km/h
Optional Equipment
Additional vehicle options (impacting CO2 and consumption) are taken into account
Cycle Time
Test lasts 30 minutes, an increase of 10 minutes
Driving Phases
More dynamic phases: 52% urban and 48% non-urban
Gear Shifts
Each vehicle has different, rather than fixed, gear shift points
Test Temperatures
Measurements now taken at 23ºC (and CO2 values corrected to 14ºC) vs 20-30ºC.
• From September 2017, all new model introductions will be subject to WLTP type approval and Real Driving Emissions (RDE) testing.
• From September 2018, all new registrations will need to comply to WLTP type approval.
• From September 2019, all new registrations will be need to comply to RDE testing. Light Commercial Vehicles (Category N1)
• From September 2018, all new Light Commercial vehicle model introductions will be subject to WLTP type approval and Real Driving Emissions (RDE) testing.
• From September 2019, all new registrations of Light Commercial Vehicles will need to comply to type approval under WLTP and all new registrations will be subject to RDE testing.
