NOx emissions from diesel cars in the EU have remained high, largely due to a growing gap between emission certification limits of Euro 4 and Euro 5 standards (measured in laboratory testing) and “real-world” emissions of diesel cars operating on the roads.
This study compares official fuel consumption values measured in laboratories with the real-world performance of 20 popular vehicle models. All models claim significant improvements in fuel efficiency since 2009, with reductions in official fuel consumption values ranging from 8 to 30 percent.
In January 2016 the EU Parliament will evaluate the RDE proposal from the European Commission's Technical Committee on Motor Vehicles (TCMV). This brief notes five things that could strengthen the regulation.
Analyzes results of emissions tests on 32 Euro 6 diesel passenger cars from 10 different manufacturers. Results show some automakers meeting diesel NOx emissions standards under more realistic driving conditions, while others lag badly.

This study, a meta-analysis of PEMS data from EU (Euro 6) and US (Tier 2 Bin 5/ULEV II) diesel passenger cars, documents the wide discrepancy that exists between official certification or type-approval emissions of nitrogen oxides (NOx) from new diesel passenger cars and actual NOX emissions from those vehicles during real-world, everyday operat
