Detroit Diesel Announces Shipment of 60,000 Pro Driver(R) Unit

    DETROIT, March 17 Detroit Diesel Corporation
(DDC) announced the shipment of the 60,000 Pro Driver unit.  Pro Driver is a
dash-mounted display which gives drivers real time information about miles per
gallon, idle time, fuel used at idle and other facts which can help improve
fuel economy.  Approximately 10% of all Series 60 powered trucks are now
equipped with Pro Driver.
    "Pro Driver continues to grow in popularity.  Sales in January 2000 were
71% higher than January 1999.  Pro Driver is easy to use and it's the only
sure way for a driver to know his current miles per gallon.  Many fleets have
incentive plans for drivers based on fuel economy, and Pro Driver makes it
easy for drivers to see how they are doing.  In addition, drivers can try
different techniques such as varying truck speed, shifting gears or using
cruise control, and instantly see the effect on miles per gallon," said Tom
Diefenbaker, Director Electronic Products, of DDC.
    Pro Driver is available from all major North American truck OEM's.  The
Pro Driver display is easily programmed by the driver for Spanish, English or
French language alternatives.
    In addition to the Pro Driver dash-mounted display, DDC also offers Pro
Driver Reports software.  Pro Driver Reports allow vehicle and engine
performance data to be easily downloaded for analysis.  Pro Driver Reports
quickly identifies the driving habits of the most fuel efficient drivers.  The
reports also make it easy to demonstrate the most fuel efficient driving
techniques to newer drivers.
    Pro Driver and Pro Driver Reports are available only from Detroit Diesel
Corporation and its authorized distributors.
