International Debuts New Family of MaxxForce Diesel Engines

November 15, 2006

WARRENVILLE, IL – International Truck and Engine Corporation, a Navistar Company, has revealed its lineup of MaxxForce International diesel power engines for 2008-model-year trucks, and provided specifications and technical details. Beginning in January, MaxxForce engines become the signature powerplant for International brand on-highway Class 4-8 commercial vehicles. In North America, the MaxxForce product line ranges from the upgraded 4.5L, V-6 MaxxForce 5 to the new MaxxForce 13 big-bore Class 8 engine. Another highlight is the all-new 6.4L MaxxForce 7.

MaxxForce engines are backed by a large North America commercial-truck dealer network with more than 900 dealer locations and 7,000 service technicians.

For 2008-model-year trucks, the MaxxForce engine lineup includes:

  • MaxxForce 5, built on International’s V-6 engine platform, features an upgraded intake throttle, a larger EGR cooler, and enhanced electronics. It will power Class 4-5 International CityStar commercial trucks with 200 horsepower and 440 ft.-lbs of torque.

  • MaxxForce 7, International’s all-new V-8 turbo, provides increased performance and responsiveness, fuel economy improvements, and quietness uncharacteristic of most commercial diesel engines. The MaxxForce 7 engine will power Class 5-7 International DuraStar series medium-duty trucks, IC brand buses, International brand commercial buses, and two vehicles in the International XT Family. MaxxForce 7 offers ratings of 200-230 hp and 560-620 ft.-lbs of torque. A 300-plus horsepower rating of the MaxxForce 7 will be offered in fall 2007.

  • MaxxForce DT is built on the DT 466 Inline 6-cylinder platform and provides reliability, durability, optimal fuel economy, improved serviceability, and lower cost of operation to owners and operators. MaxxForce DT will power Class 6-8 DuraStar and WorkStar trucks with 210-300 hp and 520-860 ft.-lbs of torque.

  • MaxxForce 9, built on International’s industry leading I-6 architecture, features a bigger EGR system, foam-molded wiring harnesses, and closed-crankcase ventilation system. The MaxxForce 9 powers Class 7-8 DuraStar and WorkStar commercial trucks with 300-330 hp and 800-950 ft.-lbs of torque.

  • MaxxForce 10, also built on the I-6 architecture, features a larger EGR system, foam-molded wiring harness, and closed-crankcase ventilation system. MaxxForce 10 powers Class 8 WorkStar and TranStar trucks with 310-350 hp and 1,050-1,150 ft.-lbs of torque.

  • MaxxForce 11 and MaxxForce 13 are International’s new big-bore diesel engines for the Class 8 truck market. These engines take advantage of recent technological advances to offer drivers a strong compacted-graphite iron cylinder block without added weight, outstanding fuel economy, excellent power characteristics, and quiet, low noise, vibration and harshness. The MaxxForce 11 will be offered in TranStar, while the MaxxForce 13 will be available in the ProStar. More technical specifications will be announced in 2007, leading up to the production launch in fall 2007.
