The vehicles now feature the high-horsepower Cummins ISX15 engine with SCR.
“Offering drivers and fleets a wide-breadth of SCR-based engine solutions, which also includes our MaxxForce 13, is just one of the ways we’re ensuring that customers get a complete lineup of reliable, high-quality products they can drive with confidence,” Jack Allen, president, North America Truck and Parts, Navistar, says.
The ISX15 engine offers robust electronic controls and horsepower ratings range from 400 to 600 hp with 1,450 – 2050 lb.-ft of torque.
While the truck has been re-launched, it’s not been overhauled. Navistar says customers can expect to see the same classically chiseled hood with an assortment of chrome options for the 9900i, while the heavy-duty PayStar 5900 delivers strength and maneuverability with its frame rail options and aluminum cab.
The company is now taking orders and production of both vehicles began earlier this month.
The 9900i is available exclusively with the ISX15 engine, while the PayStar 5900 is also available with the MaxxForce 13 engine with SCR.
This announcement comes just four months after the first ProStar equipped with the Cummins ISX15 with SCR rolled off the production line, which has been met with positive reviews.
