PRINCETON, N.J. – Heavy- and medium-duty commercial truckers knowledgeable on the upcoming 2010 EPA diesel emissions changes would mostly rather have exhaust gas recirculation technology in new diesel engines than selective catalytic reduction technology, according to an online survey conducted by Braun Research. Quantitatively, 51 percent of respondents chose EGR technology over SCR technology, while 24 percent chose SCR over EGR. The remaining 25 percent presumably had no strong siding for either position.

The survey also gauged the level of concern regarding upcoming emissions changes. When queried, more than half of survey respondents cited being “very” to “extremely” concerned. Particular areas of concern regarding the changes included: the higher prices of engines, engine reliability, additional maintenance costs, time needed to convert engines to updated standards, changes in maintenance requirements, and increased engine weight.

The survey was conducted by Braun Research in conjunction with Navistar, and included 302 respondents who have purchasing authority or influence the purchasing of heavy- and medium-duty commercial trucks.
