Navistar's Green Diesel Technology Allows California Air Resources Board to Examine Clean-Diesel Option

         Demonstration Engine in School Bus Puts Brakes on Pollution

    LOS ANGELES, Jan. 27 -- Navistar International Corporation
today demonstrated to the California Air Resources Board and
public its ability to significantly reduce harmful emissions and contribute to
cleaning up California's air.
    An International(R) brand school bus equipped with the company's
low-emission engine and advanced aftertreatment control, using an ultra-low
sulfur fuel, produced none of the smoke or fumes usually associated with
diesel.
    "We want to work with the ARB and the oil industry to preserve the diesel
option.  The benefits of diesel power in California can continue to contribute
to the state, if we work together to solve the environmental challenge," said
Patrick Charbonneau, vice president of engine engineering for Navistar's
engine and foundry group.
    Green Diesel Technology(SM) system tests show particulate matter emissions
reduced by more than 90 percent, falling within the stringent standards
proposed by the U.S. Environmental Protection Agency and the California Air
Resources Board for compliance between 2007 and 2010.  Navistar's system has
better particulate emissions than similar vehicles using natural gas; and its
gaseous hydrocarbons are reduced below measurable levels, providing a diesel
solution to the toxic emission health issue.
    Even before the availability of Green Diesel Technology, new diesel
engines have already been dramatically improved.  Modern diesel engines emit
approximately 40 percent less carbon dioxide, which is linked to global
warming and use 40 to 60 percent less fuel per mile than similar vehicles
burning gasoline.
    International(R) is a registered trademark of Navistar International
Corporation headquartered in Chicago.  In addition to selling heavy and medium
trucks and school buses under the International brand, Navistar produces mid-
range diesel engines sold under the International brand and is a private label
designer and manufacturer of diesel engines for the truck and van markets.
Sales and revenues in fiscal 1999 totaled $8.6 billion.  Additional
