International Truck and Engine Corp. on Thursday, March 22, at the Mid-America Trucking Show in Louisville, Ky., revealed the power and torque ratings for its MaxxForce 11 and MaxxForce 13 Class 8 engines, and released other news about its new ProStar Class 8 tractor. Those engines will be available by year’s end, said Jacob Thomas, vice president of the Big Bore Diesel Engines Business Unit.

Six MaxxForce big-bore models offer ratings of 330 to 475 horsepower and 1,250 to 1,700 lb.-ft. torque. The efficiency and power characteristics of the MaxxForce 11 and MaxxForce 13 are made possible in part by a high-pressure common-rail fuel system, twin-series turbochargers with interstage cooler, and Eco-Therm, International’s heat-management system, Thomas said. Eco-Therm features an innovative, multiple coolant circuit design managed by an electronically controlled coolant control valve.

The advanced fuel-and air-management systems of the MaxxForce engines provide instant response to reach peak torque at 1,000 rpm. This means earlier acceleration upshifts and fewer grade-climb downshifts, Thomas said. This keeps MaxxForce big-bore engines operating more often in the lower speed range, where fuel economy is best.

International also announced:

  • The ProStar is available with Caterpillar’s new C13 engine beginning this summer. It rounds out the Cummins and MaxxForce offerings previously announced.
  • The ProStar will have a 113-inch bumper-to-back-of-cab dimension to complement the 122-inch BBC already available, as well as a wider range of cab roof heights.
  • International is an inaugural corporate sponsor of a new association, Women in Trucking, formed to encourage women to pursue a career in trucking and also to help the industry become more open to women.
  • A ProStar with a custom paint scheme by award-winning automotive designer Chip Foose is on display, though not competing, at the Paul K. Young Truck Beauty Championship at MATS.
