Navistar First OEM to Reach 5 Million Hybrid Miles

Success with Energy-Efficient Hybrid Trucks and Buses Paves the Way for Future
Opportunities
WARRENVILLE, Ill.--(Business Wire)--
The number of owners and operators of Navistar`s hybrid-powered commercial
vehicles is growing as hybrid trucks and buses become more and more attractive
to businesses looking to "green" their fleets and improve fuel economy.

In fact, the popularity of these hybrid vehicles has helped Navistar become the
first original equipment manufacturer (OEM) to accumulate more than 5 million
real-world miles in the hands of customers driving hybrid-powered International®
trucks and IC Bus™ brand school and commercial buses.

"With a wide range of hybrid trucks and buses, we continue to be a leader in
providing energy-saving, environmentally friendly transportation solutions,"
said Jack Allen, president, Navistar`s North American truck group. "By
developing clean vehicle technologies that reduce fuel consumption and
greenhouse gas emissions, we`re able to deliver significant savings to the
customer`s bottom line and, at the same time, help them reduce their overall
carbon footprint."

Extensive Line-up of Hybrid Trucks

In less than two years, Navistar has established itself as a leader in hybrid
technology. In November 2007, Navistar launched the Class 6 medium-duty
International® DuraStar® Hybrid, becoming the first OEM to enter assembly-line
production of hybrid commercial trucks.

Building on the success of that platform, Navistar expanded its hybrid product
portfolio in October 2008 with the Class 7 International DuraStar Hybrid
Tractor, targeting general freight haulers and food/beverage distributors with
diminishing loads. This past March, Navistar introduced the Class 7 severe
service International® WorkStar® Hybrid 4x4, the industry`s first hybrid
four-wheel-drive commercial truck.

Depending on the specific application and other conditions, International hybrid
trucks can deliver up to 40 percent fuel savings in stop-and-go driving and
pick-up/delivery operations. Beyond the fuel savings potential, the hybrid
trucks produce zero emissions when auxiliary equipment (like an overhead utility
bucket) operates solely on the truck`s hybrid battery power.

"The continued success of these trucks on the road demonstrates not only the
reliability of hybrid technology, but also the potential for significant fuel
savings and emissions improvement within real-world applications," said George
Survant, director of fleet services for Florida Power and Light and chairperson
of the Hybrid Truck Users Forum (HTUF) Working Group.

Beyond Hybrid - All-Electric Delivery Vehicles

Two weeks ago, President Barack Obama traveled to Navistar`s Wakarusa, Ind.,
manufacturing facility to celebrate the award of a $39 million federal grant to
develop and build all-electric delivery vehicles. Through this U.S. Department
of Energy grant, Navistar plans to build 400 all-electric vehicles in 2010 and
expects to be producing several thousand vehicles annually within a couple of
years. This zero emissions all-electric delivery vehicle would primarily be used
by drivers for local deliveries where stop- and-go driving would otherwise
consume a large amount of fuel.

Hybrid School and Commercial Buses

In addition to its line-up of hybrid trucks and the potential for all-electric
delivery trucks, Navistar affiliate, IC Bus, offers a comprehensive portfolio of
hybrid-electric school and commercial buses. In February 2007, IC Bus was first
to enter assembly-line production of hybrid buses. IC Bus offers a
battery-powered hybrid electric system similar to that used in commercial
trucks. In addition, through its supplier partnership with Enova Systems, a
leading provider in hybrid drive systems, IC Bus is the first and only
manufacturer of a factory-built plug-in electric hybrid vehicle. An IC Bus
hybrid school bus can deliver fuel savings of up to 65 percent and reduce
greenhouse gas emissions by nearly 40 percent.

For decades, Navistar has demonstrated a commitment to clean diesel technologies
that benefit the environment and its customers. In 1989, Navistar was the first
original equipment manufacturer to release the smokeless diesel engine and, in
2001, Navistar was the first engine manufacturer to gain certification from the
U.S. Environmental Protection Agency (EPA) for meeting particulate and
hydrocarbon emissions standards - six years ahead of schedule.
