Navistar’s MaxxForce 15 Diesel Engine

May 25, 2011

Navistar’s MaxxForce 15 diesel is in production and initially available in its International PayStar 5900 series. It will go in highway models later this year. The 15-liter engine uses a block, crankshaft and other “iron” parts from the C15 formerly built by Caterpillar, Navistar’s truck partner, along with Navistar’s own electronics, fuel injection and air management systems. Its ratings go to 550 horsepower and 1,850 pounds-feet.
