BORGWARNER REPORTS SOLID FIRST QUARTER
DRIVEN BY STRONG WORLDWIDE DEMAND

Auburn Hills, Michigan, April 28, 2005 - BorgWarner Inc. (NYSE:  BWA)
today reported results for the first quarter of 2005.  The powertrain
systems supplier delivered solid results in spite of lower car and
truck production in North America and modest growth elsewhere
in the world.  Strong demand for BorgWarner technology in Europe
and Asia, along with continued cost efficiencies, helped
boost results.

First Quarter Highlights:

     .    Earnings of $1.36 per diluted share.  For comparisons with other
           quarters, earnings were $0.97 per diluted share, which included
           $0.93 per diluted share from the company's base business and
           $0.04 per diluted share cont  ributed by Beru, and excluded
	   the following:

          - The immediate write-off of the excess purchase
            price associated with Beru's in-process R&D
            of $(0.13) per share
          - Gains from divestitures of $0.11 per share
          - The release of tax accruals of $0.40 per share
     .    Sales of $1,084 million, up 20% from Q1 2004
          - Sales up 5% excluding Beru
     .    Operating income margin of 7.7%
     .    Company reiterates its 2005 full year expectations of $4.15
          to $4.25 per share on the company's base business

Comment and Outlook: "We had a strong first quarter in spite of a challenging
environment," said Tim Manganello, Chairman and CEO.  "Our results were
driven by our technology that is targeted at the fastest growing parts of the
market.  Our sales were up 5% in the quarter, excluding our acquisition of a
majority stake in Beru, while worldwide industry production was flat.  Sales
including Beru were up 20% versus first quarter 2004.  Our Engine business
had solid growth driven by demand for our technology, which improves fuel
economy, performance and air quality, while the Drivetrain business
experienced a decline in sales, primarily due to a decline in North American
light truck and sport-utility vehicle production.  Net income generated by the
base business was up slightly despite significant year-over-year increases in
steel and other commodity prices.  We clearly demonstrated the viability of our
technology-driven growth strategy and the benefits of building one of the most
diverse customer bases in the industry."

     The company said that it now expects 2005 earnings per share in a
range of $4.65 to $4.81, which includes $0.51 per share associated with
divestitures and the release of tax accruals, a $(0.13) per share loss due to
the immediate write-off of the excess purchase price associated with Beru's
in-process R&D, and full year earnings contributed by Beru of $0.12 to $0.18
per share.  Although it remains cautious on the industry, the company
reiterated its expectations of $4.15 to $4.25 per share on the company's base
business as a comparison to 2004 results.

     Financial Results:  For first quarter 2005, sales were $1,083.5 million,
up 20% from $903.1 million in first quarter 2004.  Excluding Beru, sales were
up 5% in first quarter 2005.  First quarter 2005 sales excluding Beru sales
are provided for comparisons with other quarterly results.  Net income in the
quarter was $77.6 million, or $1.36 per share, compared with $51.1 million,
or
$0.91 per share in last year's first quarter. First quarter 2005 net income
includes normalized earnings related to Beru of $2.5 million, or $0.04 per
share, $(7.4) million related to the immediate write-off of the excess pur-
chase price associated with Beru's in-process R&D, or $(0.13) per share,
$6.3 million related to divestitures, or $0.11 per share,
and $23.0 million related to the release of tax accruals resulting
from the completion of tax audits, or $0.40
per share. The normalized earnings related to Beru reflect BorgWarner's
69.42% ownership share of Beru, adjusted by BorgWarner from International
Financial Reporting Standards to U.S. GAAP, include expenses related to the
amortization of 54% of the excess purchase price and BorgWarner's
acquisition financing costs, and exclude the immediate write-off of the excess
purchase price associated with Beru's in-process R&D. The expenses related
to the amortization of the excess purchase price are based on preliminary
allocations. First quarter 2005 net income excluding earnings related to Beru,
divestitures, the release of tax accruals and the immediate write-off of the
excess purchase price associated with Beru's in-process R&D is provided for
comparisons with other quarterly results. The increase in the Euro and other
currencies added $21.2 million to sales in first quarter 2005 compared with
2004, and $1.8 million to net income.

     Operating income was $83.6 million or 7.7% of sales in first quarter
2005 versus $77.6 million or 8.6% of sales in the first quarter 2004. Research
and development spending was $41.1 million in the quarter versus $29.4
million in 2004.

     Net cash provided by operating activities was $42.4 million in first
quarter 2005 versus $66.7 million in first quarter 2004.  Investments in capital
expenditures and net tooling totaled $52.8 million for the quarter, compared
with $54.2 million for the same period in 2004.  Balance sheet debt increased
by $330.9 million, and cash and cash equivalents decreased $66.5 million in
first quarter 2005 compared with end of fourth quarter 2004, primarily due to
funding of the Beru acquisition.

     Engine Group Results:  Strong demand, and the acquisition of a
majority stake in Beru, boosted Engine Group sales 37% to $762.5 million
with a 13% increase in earnings before interest and taxes to $77.0 million.
The group continues to benefit from European and Asian automaker demand
for turbochargers, timing systems and emissions products, and from stronger
commercial vehicle production in both Europe and North America.

     Drivetrain Group Results:  Sales for the Drivetrain Group were down
8% and the earnings before interest and taxes margin deteriorated to 6.9%
from 8.5% last year.  Productivity gains in the quarter were more than offset
by declining volumes in the North American light truck and sport-utility vehicle
markets, higher commodity prices and healthcare cost increases.

     Recent Highlights:  During the quarter, the company opened its new
world headquarters in Auburn Hills, Michigan. In the BorgWarner Engine
group, a facility in Aoyama, Japan, opened to serve the company's growing
engine timing systems business in that country.

     The Engine Group also launched timing systems programs for the 6.1
- -liter V8 HEMI engine that debuts on the 2005 Chrysler 300 C SRT8 and for
the Nissan V6 truck engines that power the new Pathfinder and X-Terra SUVs
and the new Frontier pickup.  In addition, the group began production of its
first high-volume variable cam timing (VCT) systems for a new family of
General Motors V6 engines being introduced this year. This system uses a
Torsional Assist(TM) technology instead of the conventional oil-pressure
actuated approach. The new technology represents a leap to the next
generation of cam phasing and constitutes a major step in the expansion of
BorgWarner's growing engine management business.

     The Drivetrain Group announced that its DualTronic(TM) wet-clutch
and control-system technology for automated transmissions, will be available
on turbocharged direct-injected gasoline (TFSI) models of the all-new 2005
VW Jetta that went on sale in the U.S. and Canada in March.   The
technology was named a 2005 Automotive News PACE Award winner for
superior innovation, technological advancement and business performance.
With the Jetta,  seven VW/Audi vehicles are offered with this leading edge
transmission technology.

     The Drivetrain group will also provide its electronically
controlled all-wheel drive InterActive Torque Management II (ITM II)(TM)
system to the 2006 Honda Ridgeline, the mid-size front-wheel drive-
based pickup with which Honda Motor Co. officially enters the truck market.

     At 9:30 a.m. ET today, a brief conference call concerning first quarter
results will be webcast at: http://www.borgwarner.com/investor_webcasts.html.
