International Truck and Engine has announced its lineup of MaxxForce diesel engines for 2008-model-year trucks. Beginning in January, MaxxForce engines become the signature power plant for International on-highway class 4-8 trucks. The lineup includes:

MaxxForce 5, built on International’s V-6 engine platform, with a larger EGR cooler and enhanced electronics. It will power class 4-5 International CityStar commercial trucks with 200 hp and 440 lb ft of torque.

The MaxxForce 7, an all-new turbo V-8, will power class 5-7 International DuraStar medium-duty trucks as well as buses and two vehicles in the XT Family. It offers ratings of 200-230 hp and 560-620 lb ft of torque. A 300-hp-plus rating will be offered in the fall of 2007.

The MaxxForce DT is built on the DT 466 inline-six platform and will power class 6-8 DuraStar and WorkStar trucks with 210-300 hp and 520-860 lb ft of torque.

The MaxxForce 9, also built on International’s inline-six architecture, features a bigger EGR system and will power class 7-8 DuraStar and WorkStar trucks with 300-330 hp and 800-950 lb ft of torque. The similar MaxxForce 10 will find its way into class 8 WorkStar and TranStar trucks with 310-350 hp and 1050-1150 lb ft of torque.

Then there’s the MaxxForce 11 and MaxxForce 13, the new big-bore diesel engines for class 8 trucks based on a European MAN block. They sport technological advances such as a strong compacted-graphite iron cylinder block. The MaxxForce 11 will be offered in TranStar, while the MaxxForce 13 will be available in the ProStar. Their production launch will be in the fall of 2007.
