Is it really a new engine? Navistar (International) has been making diesels for a long time. I'm not familiar enough with their product line over the last several years to know if it is a new design or not, but I suspect not.
Of course, the EGR technology was new in 2010, to meet the EPA 2010 emissions requirements, but all engine manufacturers made significant changes for that.
