The official fuel consumption test is changing
In September 2017, a new official fuel consumption standardised test procedure, called the Worldwide Harmonised Light Vehicle Test Procedure (WLTP), was introduced for Europe. The new test has been developed to better reflect real-world driving behaviour, replacing the old NEDC test cycle. And means that the published fuel economy figures are designed to be closer to those you experience on the road.
The new test procedure includes:
More realistic driving behaviour (faster and more dynamic, wider temperature range)
Higher average and maximum speeds
A wider range of driving scenarios
Optional equipment and payload, different engines, transmissions and wheel sizes
Individual vehicle CO2 value
When you see the new figures, you may think that the fuel performance of your car has got worse, but it hasn’t. Remember, the published figures will more accurately reflect the fuel economy you achieve.
