CONSUMPTION AND EMISSIONS BASED ON USAGE
As a PSA Group brand, Citroën provides its customers with complete and transparent information on the consumption and pollutant emissions  of its vehicles under real-life conditions.
AN INDEPENDENT AND CERTIFIED MESURE
The PSA Group has partnered with Transport & Environment , France Nature Environnement  and Bureau Veritas  to define a protocol for measuring real-world fuel consumption and pollutant emissions.
ASSUMPTIONS AND CONDITIONS OF MEASUREMENT
This protocol predicts the real-world fuel consumption of vehicles travelling along a 57.3 mile route combining urban, rural and motorway driving. The vehicles tested travel on open routes in normal traffic conditions, with passengers and luggage. The use of air conditioning or heating is also mandatory. The routes selected have gradients representative of real-world usage*.
* This estimate is provided as a guide and for information purposes only and may vary depending on the actual usage conditions. The estimate is entirely separate from the official EU fuel consumption figures. To compare the fuel consumption or CO2 emission values of a new passenger car based on a harmonized test protocol in the European Union, reference should be made to official fuel consumption or emission figures of CO2 available on the Car Labelling ADEME website.
 Pollutants measured: Nitrous oxides (NOx) and Number of Particulates (NP)
 Transport & Environment (T&E): European environmental association specialised in establishing a sustainable transport policy
 France Nature Environnement (FNE) : French federation of nature and environmental protection associations
 Bureau Veritas : Global inspection, certification and laboratory testing company
