Navistar also announced at MATS that it would add a 15-liter diesel engine to its MaxxForce product line. A working version was on display with one of the trucks Navistar exhibited at the show. Horsepower will range from 435 to 550.
The MaxxForce 15-liter combines the basic block and architecture of Caterpillar's current C15 engine with Navistar's fuel and emissions systems. Like other MaxxForce engines, the 15-liter power plant will use exhaust gas recirculation to meet emission requirements. The engine will be available sometime after January 2010.
Navistar and Caterpillar announced in late 2008 that they had agreed to jointly develop various products. The MaxxForce 15 is the first joint product to be announced.
