50 New School Buses Featuring International(R) Green Diesel Technology(R) Engines With Ultra-Low-Sulfur Fuel to Convoy Across U.S.

5-Mile-Long Arkansas-to-California Caravan Boasts Innovative Environmental Diesel Engine Technology That Meets Strict Emissions Standards

WARRENVILLE, Ill., Nov. 9 -- We've got ourselves a convoy! A caravan of 50 environmentally friendly school buses built by IC Corporation, North America's largest school bus manufacturer, is beginning a trip Wednesday (Nov. 9) to San Francisco from the company's plant in Conway, Ark. The school buses are powered by International Green Diesel Technology(R) engines -- a solution that significantly reduces emissions and improves air quality.

"Watching these 50 Green Diesel Technology school buses leave the plant and travel across America provides our employees with a real sense of accomplishment," said Michael Cancelliere, vice president and general manager, IC Corporation. "It's a testament that customers are confident in our proven emissions technology. We strive to build the best school buses that protect passengers, deliver reliability, and help keep the environment cleaner by reducing emissions."

The school buses, outfitted with International(R) DT 466 diesel engines, departed the IC Corporation school bus plant in Conway at 8 a.m. on Wednesday to be delivered to a school bus customer in San Francisco. The convoy is traveling west along Interstate 40, passing through:

   -- Oklahoma City - arriving approximately 1 p.m. local time on Nov. 9
   -- Amarillo, Texas - arriving approximately 5:30 p.m. local time on
      Nov. 9 and departing at 7 a.m. local time on Nov. 10
   -- Albuquerque, N.M. - arriving approximately noon local time on Nov. 10
   -- Flagstaff, Ariz. - arriving approximately 6 p.m. local time on Nov. 10
      and departing at 7 a.m. local time on Nov. 11
   -- Ludlow, Calif. - fuel stop scheduled at noon local time on Nov. 11

The school buses are scheduled to stage in Gardena, Calif., on Saturday morning (Nov. 12) before being transported to their final destination in San Francisco. The caravan is expected to be about five miles long and will include an International fueling tanker carrying ultra-low-sulfur fuel to refuel the school buses. Ultra-low-sulfur fuel is a new type of diesel fuel that is in limited supply now, but will become more widely available in late 2006. It is available today under special arrangements between fuel suppliers and customers in the states of Washington and California where municipalities and school districts are the primary users.

Advantages of Green Diesel Technology School Buses

Built on International's extensive research, development, real-world testing and sales of low-emitting diesel solutions for the past five years in California, Green Diesel Technology engines utilize a diesel particulate filter and ultra-low-sulfur diesel fuel, eliminating visible emissions and odor from diesel-powered school buses. The advantages of replacing the existing school buses with buses outfitted with International Green Diesel Technology engines include:

   -- 90 percent reduction in hydrocarbons and particulate matter emissions
   -- Smokeless, odorless emissions

International Green Diesel Technology engines are the wave of the future, having already met the U.S. Environmental Protection Agency and California Air Resources Board 2007 requirements for particulate matter and hydrocarbons. Green Diesel Technology engines consist of two things: a catalyzed diesel particulate filter and ultra-low-sulfur fuel. The fuel is the enabler for the use of the filter resulting in emissions reductions. More information about it is available at http://www.greendieseltechnology.com/ .

Media Can Track the School Bus Convoy

Media will be able to track the convoy of environmentally friendly school buses in real-time because a GPS tracking solution called International(R) Aware(TM) will be provided on one of the school buses in the caravan. IC Corporation announced last week that it is the first school bus manufacturer to offer a factory-installed GPS-based tracking system in school buses beginning in 2006. Although this particular order of school buses will not include the company's tracking solution, a bus will be specially outfitted with it to track the progress of the move to California.
