Comparison, Exhaust and Low Cost

Ricardo: achieving light-duty diesel RDE NOx compliance in urban driving is possible, at a price

Green Car Congress

JUNE 11, 2016

While known technologies were shown to be capable of appropriate NO x control, they come with downsides to other product attributes, notably cost, reductant fill frequency where applicable, and ultimately, fuel consumption. The cost comparison is with respect to a Euro 5 baseline. Attribute analysis presented in SIA paper.
