LISLE, Ill. — Navistar International Corp. Monday announced that the company is shipping to customers its first 300 International ProStar+ Class 8 on-highway tractors equipped with the Cummins ISX15, achieving what the company called “another important milestone” in the launch of the company’s SCR-based clean engine technology.

“Reaching its ‘OK-to-Ship’ milestone on Dec. 14 – 5 days ahead of schedule — demonstrates the tremendous progress we’re making in delivering our first SCR-based Class 8 trucks to the marketplace,” said Troy Clarke, Navistar president and chief operating officer. “Working collaboratively and fully integrated with our Cummins colleagues, the team has beaten an aggressive launch timeline while ensuring the highest levels of quality.”

The Navistar/Cummins relationship is unlike that of any other OEM and engine supplier in the industry, Clarke said.

With 75 years of history and collaboration behind its partnership, the Navistar team has worked side-by-side with Cummins engineers to bring the ProStar+ with ISX15 to market, he said.

Since announcing its shift to SCR-based clean engine technology this past summer, Navistar has completed rigorous testing and analysis in both its captive and customer field test units, logging hundreds of thousands of driving miles in real-world conditions. “Working collaboratively, the teams have been laser-focused on a flawless execution of the launch plan, with a high attention to detail while defining and upholding stringent quality metrics,” Clarke said. “In fact, first-time quality results for the ISX program are exceeding 98 percent.”

Navistar was the only OEM not to adopt the SCR technology as a means to meet 2010 EPA standards.

Instead, the company gambled on making do with an exhaust gas recirculation (EGR) emissions solution for EPA 10.

Navistar announced in July that is was giving up on EGR.

That announcement came less than a month after a federal appeals court tossed out an EPA ruling to allow Navistar to continue to produce and sell engines that don’t meet the federal standard.

Determining Navistar to be a “technological laggard” and thus eligible for regulatory relief, EPA in January issued an interim final rule allowing manufacturers to sell non-compliant heavy-duty diesel engines in model years 2012 and 2013 as long as they pay a penalty of $1,919 per engine, with an upper limit set at 0.5 grams of nitrogen oxide per horsepower-hour — permitting emissions of up to two-and-a-half times the 0.2 grams allowed under the 2010 NOx standard with which Navistar’s competitors already comply, the court noted.

So those competitors protested, objecting to both the methods used by EPA and to the substance of the rule, arguing the agency “grossly underestimates the true cost of compliance,” and the low penalty could tempt other manufacturers to pay the penalty and sell non-compliant engines at a premium.

Since the July announcement, Dan Ustian retired as chairman, president and CEO of Navistar and Jim Hebe retired as senior vice president of North American Sales Operations.
