The work is related to the emissions testing on three vehicles of different technology, all of which Euro6d-temp compliant, and under various driving conditions, both in laboratory and on-road.

Get Real testing campaign: why new laboratory tests will do little to improve real-world fuel economy
The report shows that the CO2 emissions gap between the independently performed WLTP and NEDC tests is small, and suggests the new WLTP test procedure is likely not sufficient to reduce or close the gap between official and real-world CO2 emissions. The report also stresses the lack of transparency about vehicle data, which complicates the analysis of independent tests and makes possible cheating harder to detect.
New EU car emission tests not enough to stop carmakers’ cheating
The new Worldwide Harmonised Light Vehicle Test Procedure (WLTP), designed to improve cars CO2 emissions testing in laboratory, will not stop carmaker manipulation of test results and will not close the gap between official and real world figures a new report by Transport & Environment shows.
Interview with Dimitri Vergne, Senior Sustainable Transport Officer at European consumer organisation BEUC on the impact of the transition to WLTP on consumers
“The growing gap means consumers spend a lot more money on fuels than anticipated. According to studies by our members, motorists pay in average an extra 400€ per year for fuel”
European new car CO2 emissions are rising because of heavier, bigger diesels
Provisional data for European new car carbon emissions in 2017 published today shows the small but expected rise in new car CO2 emissions of 0.4g/km is due to the strong growth in sales of crossover and SUV models – mainly diesel powered.

A 2017 update of official and “real-world” fuel consumption and CO2 values for passenger cars in Europe
New car efficiency virtually unchanged for a fifth year. Car CO2 test results a sham, shows ICCT study.
Since 2012 new car CO2 emissions have reduced by just 2% on the road compared to nearly 11% in fake laboratory tests.
