Emissions Testing
CO2 emission and fuel consumption figures that reflect real-world scenarios.
What is WLTP?
WLTP stands for Worldwide Harmonised Light Vehicle Test Procedure and was introduced in 2017. Developed by the global automotive industry in collaboration with international legislators, it is a new testing method for vehicles that provides more realistic figures for CO₂ emissions and fuel consumption.
A Standardised Way of Testing
The WLTP driving cycle is divided into four phases, each with a different average speed: Low, Medium, High, and Extra High. Each phase reflects a variety of real driving situations - such as acceleration, braking, and stopping - based on statistical data from actual on-road driving.
To improve accuracy, the test also factors in average European temperatures and, for the first time, considers vehicles equipped with accessories like roof racks, alloy wheels, and spoilers. This broader approach makes the results far closer to real-world driving conditions.
You may also see a “combined” fuel consumption value, which merges all four phases into a single figure. This is the most realistic representation of everyday driving and is therefore the figure most often quoted by manufacturers.
Finding your Emissions Figures
WLTP figures are listed in the Full Specifications section of our website for each model. You can also speak to your local retailer for more information.
