MaxxForce 15 Debuts in PayStar Trucks

March 25, 2011

Navistar’s long awaited 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.
An integrated front-discharge mixer chassis comes this fall. It uses a drum from subsidiary Continental Mixer, plus Navistar’s MaxxForce 11 and 13 diesels. Indiana Phoenix will assemble the Continental-badged truck and Continental dealers will sell it.   
A sloped hood option provides greater forward visibility for drivers of International’s WorkStar 7600 vocational truck. The hood’s front was lowered by repositioning the radiator in the chassis. The high-hood version remains available.
WorkStars also get an updated interior, including an angled center panel and enhanced gauge trim. The current flat-dash design is still available for trucks with three-person seating.
Continental’s new lightweight mixer drum saves 2,000 pounds over a standard steel drum. It uses Hardox high-strength steel in any size that Continental now offers, and is a “non-discountable” $6,500 option.
SuperSlurry soil stabilization, a liquid system for preparing sub-bases under parking lots and other projects, will be handled by Continental, which will also license it.
