What is WLTP?
The European Union has developed a new test called the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) which came into effect on 1st September 2017 for new type approvals and 1 September 2018 for all vehicles. This will replace the current New European Driving Cycle (NEDC) test procedure for establishing the official Fuel Consumption and CO2 emissions of new cars.
The new WLTP laboratory test will also be supplemented by an emissions test that measures pollutants directly on the road: RDE (Real Driving Emissions) and was brought in to the new testing regime to provide a closer representation of ‘real-world’ fuel consumption and CO2 figures and provide model specific values at the point of sale.
