    DETROIT, June 22 -- Detroit Diesel Corporation
announced effective immediately, Osvaldo (Ozzie) Marchante is appointed
Chairman and CEO for Florida Detroit Diesel-Allison, Inc. (Florida DD-A), the
Detroit Diesel and Allison Transmission distributor for Florida.  Lee Walquist
will continue in his capacity as President of Florida DD-A.  As previously
announced, Ozzie will also continue to hold the position of Chairman of
Detroit Diesel-Allison de Mexico, S.A. de C.V. (DD-A de Mexico), the Detroit
Diesel and Allison Transmission distributor for Mexico.
    Ozzie was previously General Parts Manager for Key Power and then Vice

successfully managed this distributorship during the difficult Mexican
economic and financial crisis period.  During this period, Detroit Diesel's
penetration of the heavy-duty truck market has grown to approximately 25%,
nearly double its 1994 base.  In addition, Detroit Diesel remains the dominant
power choice for heavy-duty buses and coaches in Mexico.

assignment at a time when Detroit Diesel is launching several new product
lines, including a complete new line of four-cycle marine diesel engines.  The
sale and aftermarket support of marine engines is of particular importance in
this territory.  The addition of Mr. Marchante to the team at Florida DD-A
will further increase Detroit Diesel's support of this territory.
    Ozzie will be located at the distributor's new Ft. Lauderdale facility
which is the focal point for the Company's marine activity and which will
become the corporate headquarters for Florida DD-A.
    Detroit Diesel Corporation is engaged in the design, manufacture, sale and
service of heavy-duty diesel and alternative fuel engines, automotive diesel
