Detroit Diesel Reports All-Time Record Fourth Quarter And Full Year 1999 Earnings
    DETROIT, Feb. 3 -- Detroit Diesel Corporation
announced today record 1999 net income of $49.2 million, or $2.00 per common
share, an increase of 21% over 1998 net income (before a special charge) of
$40.5 million, or $1.64 per common share.  These earnings also represent an
increase of 23% over the company's previous record 1995 earnings of $40.1
million, or $1.62 per common share.  Total 1999 revenues of $2.4 billion were
also an all-time record.
    For the three months ended December 31, 1999, total revenues were a record
$594 million, a 6% increase over the fourth quarter 1998, and net income
increased 17% to a record $12.0 million, or $0.49 per common share, compared
to fourth quarter 1998 net income of $10.3 million, or $0.42 per common share.
Total fourth quarter 1999 engine shipments were 41,900 units compared to
37,500 units in fourth quarter 1998.
    Full year shipments increased 7% to a record 166,700 units, reflecting
strong growth in the company's Series 60, Series 2000, Series 4000, and
automotive engine sales.
    Roger S. Penske, Chairman, said, "Detroit Diesel's record 1999 performance
reflects the numerous initiatives we have implemented in recent years,
including the CCVI material cost reduction and PowerEvolution programs.
Record results were possible because of our consistent focus on cost
reduction, revenue growth in new products, and the very strong North American
truck market.  Our entire team contributed to the success we have achieved
over the last several years.  As a result of these efforts, our cash flow and
balance sheet have never been stronger, with a debt to capital ratio below
17%, and we are solidly positioned to sustain our growth plan going forward."
    Charles G. (Chip) McClure, President and CEO, added, "We are very pleased
to announce record 1999 Detroit Diesel revenues and earnings, particularly in
light of weaker than expected revenues in the energy and mining markets, and
our decision to cease production of most of our two-cycle engine products at
mid-year.  For the year 2000, our objective is to build on the strong
fundamentals for growth in our service parts and remanufactured products
operations, and to continue to implement our cost reduction plans.  These
efforts should mitigate the currently expected decline in the North American
truck market from record setting 1999 levels."
    Parts and remanufactured products revenues for the fourth quarter were
$114 million, an increase of $10 million over the fourth quarter 1998.  Total
1999 parts and remanufactured products revenues reached $440 million, as four-
cycle parts demand and an expanded lineup of remanufactured products continued
to generate growth.
    Operating income (earnings before interest and taxes) in the fourth
quarter increased 9% to a record $20.9 million compared to fourth quarter
1998.  Total 1999 operating income was $86.0 million, an increase of 15%
compared to 1998 operating income before a special charge.  Operating cash
flow during 1999 rose 50%, or $40 million, to $118 million compared to full
year 1998, and free cash flow (operating cash flow less capital expenditures)
increased $21 million to $57 million.
    Gross margin was 23.7% in the fourth quarter, an increase of 0.3
percentage points over the fourth quarter 1998.  Full year 1999 gross margin
also was 23.7%, an increase of 0.4 percentage points over 1998 gross margin
and the highest in the company's history.  A more favorable mix of engine
products, material cost reductions, and improved operating efficiencies
resulted in the gross margin improvement.
    Research and development expenses were $25.8 million for the quarter,
compared to $23.0 million in the fourth quarter 1998.  Total 1999 research and
development expenses were $105.8 million, compared to $93.9 million for full
year 1998.  The company continues to make significant investments in its new
product development and application engineering activities to maintain its
technological leadership role.
    Selling, general and administrative expenses were $93.8 million for the
quarter, compared to $89.6 million in fourth quarter 1998.  Total 1999
selling, general, and administrative expenses were $368.0 million, or 15.6% of
total revenues, compared to $355.6 million in 1998.
    In conjunction with the previously announced share repurchase program, the
company acquired 1.1 million shares of its stock during the fourth quarter at
a total cost of $20.6 million.  Current total shares outstanding are reduced
to 23.6 million.  As a result of the repurchase program, the weighted average
number of shares outstanding for the fourth quarter are 24.3 million.
Earnings per share results for both the fourth quarter and the full year were
improved by $0.01 due to the share repurchases.

    The following is a review of the Company's three markets:

    On-Highway.  Revenues increased 11% to $388 million in the fourth quarter
compared to fourth quarter 1998.  Shipments within the coach and bus sector
experienced consistent growth during 1999.  Demand within the North American
heavy-duty truck market likewise continued to be strong throughout the fourth
quarter.  Revenues from four cycle service parts continues to exhibit
significant improvement as a result of a growing in-service engine population,
represented by the nearly 600,000 Series 50 and Series 60 units in operation.
Total 1999 revenues increased 15% to a record $1.5 billion compared to full
year 1998 revenues.  Based upon early indications, it is currently anticipated
that the North American Class 8 truck market production for the full year 2000
will decline 10-15% over prior year levels.  OEM production rate reductions
are likely to take place during the first quarter of 2000, and the company has
taken steps to adjust for lower demand levels.
    Off-Road.  Revenues were $152 million in the fourth quarter compared to
$175 million in the fourth quarter 1998.  As planned, two-cycle unit volumes
within this market declined 78%, with production of the majority of these
engines was completed in mid-1999.  Acceptance of the company's four-cycle
products as part of the PowerEvolution program continues to increase through
new product applications.  Demand within the power generation, marine and
industrial sectors has exhibited improving fundamentals in the fourth quarter
and the beginning of year 2000.  Activity within the energy markets,
particularly service parts demand, has shown marked improvement in late 1999
and early 2000.  Total 1999 revenues were $620 million, compared to $724
million in 1998.
    Automotive.  Revenues increased 35% to $54 million in the fourth quarter
compared to the fourth quarter 1998.  The company recently launched its state-
of-the-art 2.5 liter 16-valve common rail automotive engine, supplementing its
product line ranging from 1.5 to 4.2 liters.  The new 2.5 liter engine, which
is scheduled for production in the fourth quarter of 2000, will be the first
2.5 liter common rail automotive engine available in Europe.  Total 1999
revenues rose 4% to $194 million compared to $186 million in 1998.
