PSA Peugeot Citroën said it was pleased to learn that the initial results obtained by the Peugeot 208 and 508 in tests organised by the technical committee led by the French Ministry of Ecology, Sustainable Development and Energy comply with regulations and are aligned with homologated data.
"These results confirm the effectiveness of the exclusive BlueHDi after-treatment system, in which selective catalytic reduction (SCR) technology is positioned upstream of the particulate filter to eliminate up to 90% of the nitrogen oxides (NOx) released by diesel engines and bring NOx emissions down to levels near those of petrol engines. At the same time, diesel engines maintain their advantage of 15% lower CO2 emissions and 20% greater fuel efficiency. BlueHDi is now recognised across the industry and by outside observers as the most effective system for treating NOx emissions," the automaker said in a statement.
Convinced by SCR's potential, PSA Peugeot Citroën developed and invested in this technology so it could be deployed in late 2013, two years before mandated by regulations. The system was then gradually added as standard equipment on all Euro 6-compliant diesel models. The development of SCR technology cost several hundred million euros. PSA Peugeot Citroën has filed some one hundred patents for BlueHDi technology which has undergone continuous development with a view to improving performance and cost in time for the new Euro 6.2 emissions standards in September 2017.
"PSA Peugeot Citroën confidently and serenely awaits the next wave of test results," the statement added.
