UPS To Test Hybrid Electric Vehicle

                       New Technology Reduces Emissions
                          and Increases Fuel Economy

    ATLANTA, June 22 -- UPS today unveiled plans to test a Hybrid
Electric Vehicle (HEV).  Developed to increase fuel economy and decrease both
harmful emissions and maintenance costs, the HEV fits the company's commitment
to use innovative technology in its daily operations.
    Developed by Navistar International Corporation, Chicago, Ill., and
Lockheed Martin Controls Systems, Johnson City, NY, the concept HEV that UPS
will test combines two familiar technologies -- conventional engines and
electric motors.  The engine turns a generator to provide electrical energy
for 24 batteries and the drive motor, which propels the vehicle.  The
batteries boost the electric motor during peak power needs.  Regenerative
braking uses the motor as a brake and recaptures the vehicle's energy that is
then stored in the batteries for future use.
    "HEV technology is of particular interest to UPS because of its potential
to reduce vehicle emissions, economize on fuel in stop-and-go situations and
reduce maintenance requirements to the drivetrain," said Mike Eskew, UPS
senior vice president of engineering.
    The HEV provides higher fuel economy and emits fewer particulates than its
standard diesel counterpart.  Moreover, the HEV's sealed electric motor and
long-life batteries require no maintenance.
    The Navistar/Lockheed Martin concept vehicle design uses an
International(R) medium truck chassis and school bus chassis from Navistar,
along with an International(R) T444E diesel engine.  The HybriDrive(TM)
optimized control systems were developed by Lockheed Martin.
    The 18-month UPS test trials in three different climatic and environmental
areas Johnson City, NY, Atlanta, GA, and Los Angeles, CA -- will help
determine the commercial viability of the vehicle.  Specifically, UPS tests,
beginning in late summer, will solicit driver feedback; determine emissions
measurements; and examine fuel conservation, maintenance issues, speed,
acceleration and grade performances.
    "During this phase of testing, we're interested in verifying the technical
goals we've set for the HEV," said George Campbell, manager, truck business
development, Navistar.  "And we are relying on UPS to truly test the concept
vehicle in the stop-and-go situations of daily package deliveries.  There is
no tougher test.  We joined with UPS to conduct the tests because UPS is an
industry leader known for its use of innovative technologies."
    UPS continues its tradition of seeking environment-friendly technologies
that increase efficiency and decrease emissions.  UPS environmental
initiatives include the re-engineering of its air fleet to reduce aircraft
noise and improve fuel-efficiency; development of a powerful computer network
that efficiently dispatches its vehicles; and, creation of reusable express
envelopes.
    UPS is the largest package delivery company in the world, serving more
than 200 countries and territories and delivering more than 12 million
packages every working day with an unmatched array of product options and
commitment to service.  Headquartered in Atlanta, Ga., the company employs
326,000 and posted 1997 revenues of $22.5 billion.
