LOUISVUILLE, KY. It was standing room only this morning in the International Truck and Engine Corp. exhibit at the Mid-America Trucking Show as the company announced the power and torque ratings for the new MaxxForce 11 and MaxxForce 13 diesel truck engines. The stage was surrounded on all sides by a display showcasing International’s complete line of model year 2008 trucks and MaxxForce engines, the latest in a line of products that stretches back 175 years.

“Today we have a large, global footprint,” noted Jacob Thomas, vp of International’s Big Bore Diesel Engine Business Unit. This gives us the technical expertise and the global scale to invest in developing best-in-class products.

The six new MaxxForce engine models for the Class 8 market provide up to 1,700 lb.-ft. of torque at 1,000 rpm with ratings between 330 and 475 hp. The in-line, 6-cyl. twin-series turbo-charged MaxxForce 13 has a horsepower range of 410-475 hp., designed to deliver 1,450-1,700 lb.-ft. of torque.

The in-line, 6-cyl. 10.5 liter MaxxForce 11 has a horsepower range of 330 to 390 hp. and delivers 1250 to 1450 lb.-ft. of torque. Both engines feature a compacted-graphite iron cylinder block, high-pressure common-rail fuel system, overhead cam with roller lifters and isolated oil pan.

In the case of the MaxxForce engines, however, the total is greater than the sum of its parts. “These are our best products ever,” said Thomas. “This is the first Class 8 engine designed in and for the 21st century. They feature unprecedented integration—a true systems approach to 2007 compliance. According to Thomas, there are numerous benefits from this integrated approach, including improved fuel economy, excellent power characteristics, lower and less harsh noise and vibration and higher strength without greater weight.

The new Class 8 engines are the latest addition to the MaxxForce lineup, which also includes engines for the Class 4 -7 market.

International also announced that its flagship ProStar Class 8 tractor will be available with Caterpillar’s new C13 engine beginning this summer, as well as a new 113-in. BBC length option and a wider range of roof heights and new driver amenities.
