Las Vegas, Nevada - January 23, 2007
– With the 2007 emissions standards for diesel engines coming into play, International Truck, a Navistar company, has invested in developing a new hood design on its International® WORKSTAR™ trucks to increase the capacity of the 2007 Environmental Protection Agency (EPA) engine cooling requirements. As a result of these requirements, International decided not to relocate the larger radiator down between the frame rails so that the trucks will still be able to provide direct front engine PTO options for even the most demanding stationary applications such as well-drilling, oil field, remote power generators and field service pumpers. Additionally, the design allows for other non-stationary applications, including concrete mixers, refuse trucks and snow plows.

"Not only will the International WorkStar have a more robust hood, we are still able to provide customers with the option for direct front PTOs," said John Wadden, director of severe service marketing, International Truck. "With the high demands of construction, municipal and waste industries, maintaining the front PTO option is an important feature to our customers. The new hood design provides easy access to the engine compartment for maintenance and continues with the bold look of the International WorkStar."

International's new hood design includes an innovative multi-piece layout with the purpose of only having to replace one of the pieces in the event of any damage. This helps the customer avoid paying a high price for an entirely new hood, when they have the option to replace just the damaged portion of the hood at a significantly lower cost. All of the parts for the new hood design will be available at the more than 900 International dealer locations across North America.

In addition to the enhanced hood design, the new look of the International WORKSTAR™ will include:

• Dual air intakes
• Rounded headlights
• Hood hatch (ideal for snow plow applications)
• Robust and sturdy front fender extensions
• Larger bold chrome grille
• New interior

The new design will accommodate International® engines and engines from CAT and Cummins. In late 2007, the WorkStar will debut MaxxForceTM 11 and MaxxForce 13 big bore engines. International's trucks will be fully compliant with the EPA's 2007 mandates. The hood of the International® PAYSTAR™ Series – the other line of severe service trucks – will remain the same.
