Navistar Re-launches Truck Portfolio with Cummins Power

Navistar has re-launched its classic International 9900i tractor and PayStar 5900 SBA vocational models featuring the Cummins ISX15 engine equipped with selective catalytic reduction (SCR) technology to make it compliant with heavy-truck emission regulations.

Offered with ratings from 400 to 600 hp with 1,450 to 2050 lb.-ft worth of torque, Navistar said the Cummins ISX15 will be the only engine available for the 9900i, while the PayStar 5900 can be spec’d with either the ISX15 or the OEM’s own MaxxForce 13 SCR-equipped engine.

The truck maker unveiled its Cummins-powered vocational models at ExpoCam, Canada's National Truck Show, in part to highlight the company’s presence north of the border, according to Mark Belisle, president of Navistar Canada.

“Canada can be tough on a vehicle and the power of the ISX15 makes our already rugged vehicles adaptable for any environment,” he added. “And, with more than 7,000 vehicles on the road today, the 9900i and 5900 SBA have proven durability.”

Navistar noted that production of both vehicles began earlier this month, some four months after the first International ProStar highway tractor equipped with the Cummins ISX15 with SCR rolled off the assembly line.

With their tail between their legs, Navistar went looking for someone/anyone to provide a compliant engine.

Only way they could stay relevant in the big truck market

International Harvester had a long and close relationship with Cummins and Detroit Diesel for truck power (but of course now Detroit Diesel is merely a Mercedes-Benz engine with a DD nameplate - another U.S. truck-related company purchased by the Europeans).

The company's own mid-range engines like the DT466 originated from the company's legendary agricultural and construction machinery units (their sale in 1985 and 1982 respectively, another sad day and a major step backward for American industry).

IH's TD-20H was so good that Dressta was still producing this dozer thru 2005.

The massive TD-24 with its I-H D-1091 diesel, for a time the world's most powerful crawler, was sold around the world. Interestingly, it was started on gasoline and then switched to diesel after it warmed up (as opposed to CAT which used a separate 2-cylinder starting engine).

Both the 442B PayScraper and the 50-ton 350B PayHauler off-highway dump were best-in-class.

No, not at all. Ustian thought he could take MAN's "Massive EGR" (MEGR) technology and ramp it up to EPA2010 (Euro 6).

MAN had realized their advanced EGR technology (as it stands today) was only good up to Euro-5 (roughly EPA2007). How Ustian thought he could be smarter than MAN's EGR engineers is the real mystery.

What with the Germans and Swedes using their own engines (Freightliner, Western Star, Mack), Ustian wanted to emulate Paccar and have their own proprietary engine line-up. That much made reasonable sense.

MAN was interested in licensing the D20 and D26 to Navistar, provided they didn't sell them outside the US market. It was a win-win deal. MAN indeed designs some of the most advanced heavy truck engines in the world. But it was Ustian that thought he could take these engines in EGR spec from Euro-5 to Euro-6. MAN went to SCR for Euro-6 on its own trucks.

problem is cummins is the next worse option. ive heard so many horror stories with 2010 and newer cummins powered trucks that i wouldnt touch one

If Navistar had been able to figure out how to make their EGR engines work it would have been a huge success for the company. No DEF! That alone would drive sales. That said, put all your eggs and one basket and you are one sad puppy when the handle breaks. I hope Navistar can reverse its fortunes before the likes of VW or Fiat come back around.

Now that Navistar has opted to use the Cummins ISX 15L motor, how will that effect the CAT relationship now that its clear the MAXXForce 15L is dead?

Keeping in mind the MAXXforce 15L is the redressed CAT C-15.

That and the CAT truck is basically a Navistar truck, will CAT be upset or loosing any money on the now non use of the C15 design?

Let the Lawsuits begin!!!!

My understanding is that CAT wanted to pull the plug, but the Cat dealers (there's just a handful of dealer groups that dominate the country) put CAT against the wall, arguing that because CAT had forced them to invest deeply in all-new "truck shops" in support of the new CAT truck range, cancelling the CAT truck after that significant investment was out of the question.

One thing's for sure - the CAT trucks aren't selling. With an SCR engine, there's nothing actually wrong with the truck though.

Like what kind of Cummins issue- just the big one? (15)
