The company completed launching its heavy-duty truck line with Cummins SCR by introducing the ProStar truck the last week of April 2013 powered by the newly certified MaxxForce 13-liter engine with SCR.
“The company is turning its focus to adding SCR aftertreatment to its medium duty products,” according to its second-quarter financial report.
For the second quarter of 2013, Navistar's truck segment recorded a loss of $109 million, compared with a year-ago second-quarter loss of $45 million. Navistar says the loss was mainly driven by a decline in traditional truck volumes due to reduced industry purchasing and “the market share impact of the company's emissions transition,” the press release said. There were also $57 million in adjustments to pre-existing warranty costs.
