The old lab test – called the New European Driving Cycle (NEDC) – was designed in the 1980s and became outdated today due to several evolutions in technology and driving conditions. The European Union has therefore prepared a new test, called the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) that applies from September 2017.

Each drive cycle must include speed-vs-time data. Note that tThe torque depends on the vehicle characteristics (mass, gearbox, transmission, etc), driving conditions (gradeability, friction, drag

For electric vehicles, for example, a car with a range of 400 km according to the NEDC has a range of only slightly over 300 km according to the WLTP. The new “Worldwide harmonized Light-duty vehicles Test Procedure” (WLTP) will apply to the type approval of new passenger cars across the EU since September 1, 2017. It will succeed the NEDC (New European Driving Cycle), which has been in force since 1992.

Now, you can easily compare conflicting data. NEDC vs. WLTP: Which is More Accurate? In Europe, the NEDC was established in the 1980s and was last updated in 1997. In addition to being old and outdated, this test cycle is viewed less favorably because of its lab-based approach that collects data under ideal conditions rather than scenarios that are more representative of real-world driving.

NEDC (New European Driving Cycle) WLTP, som står för Worldwide harmonized Light vehicles Test Procedure, körs i laboratorium på 

The WLTP cycle (Worldwide Harmonized Light Vehicle Test Procedure) is, therefore, now the measure of all things. Originally, it was intended as a worldwide, harmonized test procedure.

As reported by wltp.cycles.cycle_phases (), and neglecting the advice to optionally add a final 0 when calculating the cycle Acceleration (Annex 1 2-3.1), the following 3 phasing are identified from velocity traces of 1Hz: V: phases for quantities dependent on Velocity samples, overlapping split-times.

How does WLTP affect me? Today we’ll talk fuel economy - the stuff that manufacturers tell us, and results I give you in my reviews.

If the ambient test tem-perature is also changed for the EU-WLTP (to 14 °C instead of 23 °C), an additional correction of 2 g CO 2 /km would be appropriate, making the target 102 g CO 2 /km.
