HOW DOES IT WORK?
The new test procedure will apply to all new car registrations from September 2018 and must be certified according to the WLTP test procedure, and no longer on NEDC.
The WLTP driving cycle is divided into four parts with different average speeds. Each part contains a variety of driving phases, stops, acceleration and braking phases. For a certain car type, each powertrain configuration is tested with WLTP for the car’s lightest (most economical) and heaviest (least economical) version.
WLTP was developed with the aim of being used as a global test cycle across different world regions, however whilst WLTP has a common global ‘core’, the European Union and other regions will apply the test in different ways depending on their road traffic laws and needs.
