In 2015, the ICCT commissioned Emissions Analytics, a commercial test house specializing in testing real-world fuel consumption and emissions, to perform on-road testing of Euro 6-regulated gasoline and diesel vehicles. Emissions Analytics tested 7 vehicles between 2015 and 2016 for emissions of carbon monoxide (CO), carbon dioxide (CO2), nitric oxide (NO), nitrogen dioxide (NO2), and particulates. The vehicles selected for testing were a Ford Focus, Volkswagen Golf, Citroën C4, Mercedes-Benz C220, Vauxhall/Opel Astra, Volkswagen Transporter and Volkswagen Caddy C20. The Ford Focus and the Volkswagen Golf were gasoline direct injection vehicles, while the rest were diesel. The detailed testing results can be found in the full report available below.
