Warrenville, Illinois - November 06, 2006
– International Truck and Engine Corporation, a Navistar Company, today announced 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 4.5-liter V-6 MaxxForce 5 to the new MaxxForce 13 big-bore Class 8 engine. Another major highlight is the all-new 6.4-liter MaxxForce 7.

“We offer a family of products that meets the needs of a wide array of commercial truck applications,” said Jack Allen, president, International Engine Group. “MaxxForce-branded engines are designed to deliver what customers expect: power, performance, reliability and durability while providing new lower emissions that contribute to a cleaner environment.

“‘Always Performing’ captures the essence of the MaxxForce brand,” Allen said. “The MaxxForce brand makes clear our promise that our customers get the best performing diesel with the best performing organization behind it.”

MaxxForce engines stand for performance – reinforcing International’s commitment to high-quality trucks and engines – and are backed by the largest commercial-truck dealer network in North America with more than 900 dealer locations and 7,000 service technicians.

Introducing the MaxxForce engine lineup

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 the fall of 2007.
• MaxxForce DT is built on the legendary 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, which provide increased reliability and durability. 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 in order to provide increased reliability and durability. 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 the fall of 2007.

Emissions Confidence

None of the enabling technologies being used to meet 2007 EPA emissions standards are new to International. It demonstrated 2007 EPA emissions levels for particulate matter seven years ago with its Green Diesel Technology particulate filters, and now has years of field experience with Green Diesel Technology and Ultra-Low-Sulfur-Diesel. International has also had EGR technology for NOx emissions control in production for more than 4 years and has also had closed-crankcase ventilation systems on its diesel engines to comply with Class 2-3 GVW standards for several years.

MaxxForce engine-powered International® brand commercial trucks in North America offer the proven engine technologies and advanced aftertreatment systems necessary to deliver uncompromised performance while meeting stringent 2007 U.S. EPA emissions standards for diesel engines.

By focusing on three core goals: providing clean air with improved performance, never sacrificing reliability or durability and preserving the fuel economy advantage of diesel, it continues to be the leader in the production of near-zero emissions engines and trucks and a leader in the diesel industry’s efforts to improve the nation’s air quality.
