Navistar is shipping its first 300 Cummins ISX15-equipped International ProStar+ Class 8 on-highway tractors to customers five days ahead of schedule, the company announced this week.
Since announcing its shift to SCR-based clean engine technology this summer, Navistar has completed testing and analysis in both its captive and customer field test units, combining efforts with Cummins. The International ProStar+ with MaxxForce 13 and Cummins Emission Solutions SCR-based aftertreatment system is on track for initial pilot production in March 2013 with regular production to begin in April 2013, the company says. The remaining line-up of heavy-duty truck models will transition to SCR-based clean engine technology in a phased launch throughout 2013 based on volume and customer demand, the company says.
