International dealerships across North America now are taking orders for the MaxxForce 11 and MaxxForce 13 big-bore diesel engines. The engines are offered as an option exclusively in International ProStar linehaul tractors, TranStar regional haul tractors and WorkStar severe service vehicles. Six models range from 330 to 475 horsepower and 1,250 to 1,700 lb.-ft. of torque.
Built on a compacted graphite iron block, the engines feature fuel-system electronics, air management, EGR and aftertreatment technologies developed by International specifically for high performance with low emissions. International says these features deliver outstanding fuel economy, excellent power and torque, quiet operation with low noise and vibration, and strength without added weight.
The new engines are a collaboration between International and MAN Nutzfahrzeuge. They will be manufactured at a new International plant in Huntsville, Ala.
