     Certain statements contained or incorporated by reference in this
prospectus, including without limitation, statements containing the words
"believes," "anticipates," "hopes," "intends," "expects," "will," "plans," and
other similar words may constitute "forward-looking statements" within the
meaning of the Private Securities Litigation Reform Act of 1995. All statements,
other than statements of historical fact contained or incorporated by reference
in this prospectus, that we expect or anticipate will or may occur in the
future, including, without limitation, statements included in this prospectus
under "About BorgWarner Inc." and located elsewhere in this prospectus regarding
our financial position, business strategy and measures to implement that

statements, and there can be no assurances that the actual results or
developments anticipated by us will be realized or, even if substantially
realized, that they will have the expected consequences to, or effects on, us
and our subsidiaries or our business or operations. Given these uncertainties,
prospective investors are cautioned not to place undue reliance on those
forward-looking statements. All subsequent forward-looking statements
attributable to us or persons acting on our behalf are expressly qualified in
their entirety by any of those factors described above and in the documents
containing such forward-looking statements. We disclaim any obligation to update
or to announce publicly any updates or revisions to any of the forward-looking
statements contained or incorporated by reference in this prospectus to reflect
any change in our expectations with regard thereto or any change in events,
conditions, circumstances or assumptions underlying the statements.

                                    RISK FACTORS

     An investment in our securities involves a high degree of risk. You should
carefully consider each of the following risks and all of the other information
included or incorporated by reference in this prospectus before you make any
decision to invest in our common stock. You should also refer to the discussion
above under the heading "Forward-Looking Statements."

     You should carefully consider the following factors before you make any
decision to invest in the common stock described in this prospectus:

Our industry is cyclical and our results of operations will be adversely
affected by industry downturns.

     Automotive and truck production and sales are cyclical and sensitive to
general economic conditions and other factors. For example, as compared to 2000,
automotive and truck production in 2001 decreased in North America and, to a
lesser degree, in Asia, while Europe experienced a slight increase. As a result,
our sales from ongoing businesses declined by 7.2% during 2001. Significant
reduction in automotive or truck production in any of the above geographic areas
would have a material adverse effect on our sales to original equipment
manufacturers and our financial position and operating results.

We are dependent on sport utility vehicle and light truck market segments.

     Some of our products, in particular four-wheel drive transfer cases, are
currently used exclusively in four-wheel drive systems for sport utility
vehicles and light trucks. For 2001, sales of four-wheel drive transfer cases
represented approximately 20% of our total consolidated revenue. Any significant
reduction in production in this market segment or loss of business in this
market segment would have a material adverse effect on our sales to original
equipment manufacturers and our financial position and operating results.

We face strong competition.

     We compete worldwide with a number of other manufacturers and distributors
that produce and sell products similar to ours. Price, quality and technological
innovation are the primary elements of competition. Our competitors include
vertically integrated units of our major original equipment manufacturer
customers, as well as a large number of independent domestic and international
suppliers. We are not as large as a number of these companies and do not have as
many financial or other resources. The competitive environment has changed
dramatically over the past few years as our traditional U.S. original equipment
manufacturer customers, faced with intense international competition, have
expanded their worldwide sourcing of components. As a result, we have
experienced competition from suppliers in other parts of the world that enjoy
economic advantages, such as lower labor costs, lower health care costs and, in
some cases, export or raw materials subsidies. Increased competition could
adversely affect our businesses.

We are under substantial pressure from original equipment manufacturers to
reduce the prices of our products.

     There is substantial and continuing pressure on original equipment
manufacturers to reduce costs, including costs of products we supply. Although
original equipment manufacturers have indicated that they will continue to rely
on outside suppliers, a number of our major original equipment manufacturer
customers manufacture products for their own uses that directly compete with our
products. These original equipment manufacturers could elect to manufacture such
products for their own uses in place of the products we currently supply. We
believe that our ability to develop proprietary new products and to control our
costs will allow us to remain competitive. However, we cannot assure you that we
will be able to improve or maintain our gross margins on product sales to
original equipment manufacturers or that the recent trend by original equipment
manufacturers towards increased outsourcing will continue.

     Annual price reductions to original equipment manufacturer customers appear
to have become a permanent feature of our business environment. In  2001 and
2000, the combination of price reductions to customers and cost increases for
material, labor and overhead, totaled approximately $37 million and $16 million,
respectively. To maintain our profit margins, we seek price reductions from our
suppliers, improve production processes to increase manufacturing efficiency,
update product designs to reduce costs and develop new products the benefits of
which support increased pricing. Our ability to pass through increased raw
material costs to our original equipment manufacturer customers is limited, with
cost recovery less than 100% and often on a delayed basis. We cannot assure you
that we will be able to reduce costs in an amount equal to annual price
reductions and increases in raw material costs.

We rely on sales to several major customers.

     Our worldwide sales in 2001 to Ford Motor Company, DaimlerChrysler and
General Motors Corporation constituted approximately 30%, 21% and 12%,
respectively, of our 2001 consolidated sales. The corresponding percentages for
2000 were 30%, 19% and 13%. No other single customer accounted for more than 10%
of our consolidated sales in 2000 or 2001. Our 2001 consolidated sales do not
include the approximately $300 million of sales made by our unconsolidated joint
ventures. If sales from these unconsolidated joint ventures were included in
2001 consolidated sales, our worldwide sales to Toyota Motor Corporation and its
affiliates would be approximately 7% of consolidated sales.

Although we have had long-standing relationships with each of Ford,
DaimlerChrysler, General Motors and Toyota and have sold a wide variety of
products to various divisions of each company globally, the loss of any
significant portion of our sales to any of these customers would have a material
adverse effect on our financial position and operating results.

We are sensitive to the effects of our major customers' labor relations.

     All three of our primary North American customers, Ford, DaimlerChrysler
and General Motors, have major union contracts with the United Automobile,
Aerospace and Agricultural Implement Workers of America. Because of domestic
original equipment manufacturers' dependence on a single union, we are affected
by labor difficulties and work stoppages at original equipment manufacturers'
facilities. Any work stoppage could have a material adverse effect on our
financial position and operating results. For example, we lost approximately $25
million in revenue as result of the 1998 54-day strike by the union at General
Motors.

A significant part of our labor force is unionized.

     As of December 31, 2001, approximately 40% of our domestic hourly employees
were unionized. Our two most significant domestic collective bargaining
agreements are for our Muncie, Indiana plant and our Ithaca, New York plant. The
Muncie agreement expires in March 2006 and the Ithaca agreement expires in
October 2003. The hourly workers at our European facilities are also unionized.
While we believe that our relations with our employees are good, a prolonged
dispute with our employees could have a material adverse effect on our financial
position and operating results.

We are subject to extensive environmental regulations.

     Our operations are subject to laws governing, among other things, emissions
to air, discharges to waters and the generation, handling, storage,
transportation, treatment and disposal of waste and other materials. We believe
that our business, operations and activities have been and are being operated in
compliance in all material respects with applicable environmental and health and
safety laws. However, the operation of automotive parts manufacturing plants
entails risks in these areas, and we cannot assure you that we will not incur
material costs or liabilities as a result. Furthermore, through various
acquisitions over the years, we have acquired a number of manufacturing
facilities, and we cannot assure you that we will not incur materials costs and
liabilities relating to activities that predate our ownership. In addition,
potentially significant expenditures could be required in order to comply with
evolving environmental and health and safety laws that may be adopted in the
future.

     We believe that the overall impact of compliance with regulations and
legislation protecting the environment will not have a material adverse effect
on our future financial position or operating results, but we cannot assure you
that this will be the case. Capital expenditures and expenses in 2001
attributable to compliance with environmental laws were not material.

We may have liability under environmental laws.

     We and certain of our current and former direct and indirect corporate
predecessors, subsidiaries and divisions have been identified by the United
States Environmental Protection Agency and certain state environmental agencies
and private parties as potentially responsible parties at various hazardous
waste disposal sites under the Comprehensive Environmental Response,
Compensation and Liability Act and equivalent state laws. As a result, as of
June 30, 2002, we may be liable for the cost of clean-up and other remedial
activities at 43 of these sites.

     Based on information available to us, we have established a reserve in our
financial statements for indicated environmental liabilities, with a balance of
approximately $23.2 million at June 30, 2002. We currently expect this amount to
be expended over the next three to five years.

     We believe that none of these matters, individually or in the aggregate,
will have a material adverse effect on our future financial position or
operating results, either because estimates of the maximum potential liability
at a site are not large or because liability will be shared with other
potentially responsible parties. However, we cannot assure you of the ultimate
outcome.


                               ABOUT BORGWARNER INC.

We are a leading global supplier of highly engineered systems and components for
powertrain applications. Our products help to improve vehicle performance, fuel
efficiency, handling and air quality. Our products are manufactured and sold
worldwide, primarily to original equipment manufacturers of passenger cars,
sport utility vehicles, trucks and commercial transportation products. We
operate manufacturing and technical facilities in 50 locations in 14 countries
serving customers in North America, South America, Europe and Asia, and we are
an original equipment supplier to every major automotive OEM in the world. We
have five reportable operating segments: Air/Fluid Systems, Cooling Systems,
Morse TEC, TorqTransfer Systems and Transmission Systems.

     Air/Fluid Systems.  For the six months ended June 30, 2002, Air/Fluid
Systems had sales of $205.4 million, accounting for 15% of our sales during that
period. Air/Fluid Systems accounted for $357.8 million (15%) of our consolidated
2001 net sales before divested operations, businesses held for sale and
intersegment eliminations. Air/Fluid Systems designs and manufactures
sophisticated electro-mechanical, mechanical and electronic components and
systems used for automated transmissions, fluid  pumps, engine air intake
modules, engine emission controls and actuation  systems. Key products for
transmission controls include single-function solenoids, complex solenoids and
multi-function modules. We also manufacture a wide variety of fluid pumps,
including engine hydraulic pumps for variable cam timing and engine lubrication.
Key products for  engine air intake management include throttle bodies, intake
manifolds,  throttle position sensors and complete engine induction systems. We
also manufacture products to control emissions and improve gas mileage, such  as
electric air pumps, air control valves and exhaust gas recirculation valves.
These products are provided from facilities in the United States and France.

     Cooling Systems.  For the six months ended June 30, 2002, Cooling Systems
had sales of $115.8 million, accounting for 8% of our sales during that period.
Cooling Systems accounted for $220.5 million (9%) of our consolidated 2001 net
sales before divested operations, businesses held for sale and intersegment
eliminations. Cooling Systems, our newest segment, is a combination of the
businesses acquired from Eaton Corporation and the Schwitzer cooling businesses
acquired as part of the Kuhlman Corporation acquisition in 1999. Cooling Systems
is a global provider of engine cooling solutions. Cooling Systems manufactures
and markets air sensing fan drives that can be mechanically or electronically
controlled, and also manufactures and markets polymer fans for engine cooling
systems. Product features provide improved fuel economy and emissions control by
minimizing parasitic power loss. These advanced cooling systems products are
manufactured by QS Quality Certified facilities in the United States, Germany,
the United Kingdom, Brazil, Korea and China. We believe that we are a leading
global supplier of such products, but we compete with other large independent
producers and divisions of our original equipment manufacturer customers. This
business serves the light, medium and heavy vehicle markets, as well as selected
off-highway applications.

     Morse TEC.  For the six months ended June 30, 2002, Morse TEC had sales of
$512.2 million, accounting for 37% of our sales during that period. Morse TEC
accounted for $869.4 million (37%) of our consolidated 2001 net sales before
divested operations, businesses held for sale and intersegment eliminations.
Morse TEC manufactures chain and chain systems, including HY-VO(R) front-wheel
drive transmission chain and four-wheel drive chain, MORSE GEMINI(R) Chain
Systems, timing chain and timing chain systems, crankshaft and camshaft
sprockets, chain tensioners and snubbers and turbochargers for passenger car and
commercial vehicle applications. These products are provided from facilities in
North America, South America, Europe and Asia.

     HY-VO(R) chain is used in transmissions and for four-wheel drive transfer
case applications. Transmission chain is used to transfer power from the engine
to the transmission. Our MORSE GEMINI(R) Chain System emits significantly less
chain pitch frequency noise than conventional transmission chain systems. The
chain in a transfer case distributes power between the front and rear output
shafts which, in turn, drive the front and rear wheels. We believe that we are
the world's leading manufacturer of chain for front-wheel drive transmissions
and four-wheel drive transfer cases.

     Our timing chain system is used on Ford Motor Company's family of overhead
cam engines, including the Duratech and Triton and new inline 4 cylinder
engines, as well as Chrysler's 2.7 liter, 3.7 liter and 4.7 liter overhead cam
engines. We have been selected to provide timing systems for a number of
Japanese and European applications. We believe that we are the world's leading
manufacturer of timing chain systems.

     This segment also provides turbochargers for passenger car, commercial
vehicle and industrial applications for diesel and gasoline engine manufacturers
in Europe, North America, South America and Asia. A turbocharger is a device
designed to force additional intake air into the engine to create a cleaner and
more powerful ignition. Benefits of turbocharging in both passenger car and
commercial vehicle applications include greater power for a given engine size,
improved fuel economy and significantly reduced emissions. We believe that we
are a leading manufacturer of turbochargers worldwide.

     TorqTransfer Systems. For the six months ended June 30, 2002, TorqTransfer
Systems had sales of $297.5 million, accounting for 22% of our sales during that
period.  TorqTransfer Systems accounted for $500.1 million (21%) of our
consolidated 2001 net sales before divested operations, businesses held for sale
and intersegment eliminations.  TorqTransfer Systems' products
include four-wheel drive and all-wheel drive transfer cases and
torque management systems to
transfer torque within the drivetrain for rear-wheel drive and front-wheel drive
based vehicles. The main focus is on electronically controlled torque management
devices and systems. These products are provided from facilities in North
America, Asia and Europe.

     Transfer cases are installed primarily on light trucks and sport utility
vehicles. A transfer case attaches to the transmission and distributes torque to
the front and rear axles for four-wheel drive, improving vehicle control during
off-road use and in a variety of road conditions. We have designed and developed
an exclusive four-wheel drive TORQUE-ON-DEMAND(R) transfer case system, which
allows vehicles to shift automatically from two-wheel drive to four-wheel drive
when electronic sensors indicate it is necessary. The TORQUE-ON-DEMAND(R)
transfer case is available on the Ford Explorer, the best selling sport utility
vehicle in the United States in 2000, 1999 and 1998, and the Ford Expedition,
Lincoln Navigator, Isuzu Trooper and SsangYong Musso. In 2001, this technology
was also adopted by Hyundai for its Terracan SUV, and has been launched on the
Kia Sorento in 2002.

     Sales of four-wheel drive transfer cases represented 20%, 19% and 22% of
our total revenues for 2001, 2000 and 1999, respectively. We believe that we are
the world's leading independent manufacturer of four-wheel drive transfer cases,
producing approximately 1 million transfer cases in 2001. Our largest customer
of four-wheel drive transfer cases is Ford. We supply the majority of
 the four-wheel drive transfer cases for Ford, including those
installed in the Ford
Explorer, the Ford Expedition, the Ford F-150 and Ranger pick-up trucks, the
Mercury Mountaineer and the Lincoln Navigator.

     Our newest four-wheel drive product is the INTERACTIVE TORQUE
MANAGEMENT(TM) system. This product was introduced on the Acura MDX in 2000 and
has been launched on the New Honda Pilot in 2002. This product uses
electronically controlled clutches to distribute power to the individual rear
wheels when traction is required. We are actively involved in developing this
technology for new applications in front-wheel drive based crossover vehicles
and passenger cars. A variant of this product, ITM 1, (TM) which features a
single clutch pack in front of the rear axle differential, has been launched on
the Hyundai Santa Fe in 2002.

     Transmission Systems.  For the six months ended June 30, 2002, Transmission
Systems had sales of $244.6 million, accounting for 18% of our sales during that
period. Transmission Systems accounted for $428.8 million (18%) of our
consolidated 2001 net sales before divested operations, businesses held for sale
and intersegment eliminations. We engineer and manufacture components for
automatic transmissions and the systems that combine such components in North

USE OF PROCEEDS

     The selling stockholder will receive all of the proceeds from the sale of
the common stock offered under this prospectus.

THE SELLING STOCKHOLDER

     This prospectus covers the sale of up to 100,000 shares of common stock
which we will contribute to the BorgWarner Inc. Benefit Plans Investment Trust,
the selling stockholder, prior to the effectiveness of the registration
statement of which this prospectus is a part . The Northern Trust Company
("The Northern") is trustee of the selling stockholder which is a trust holding
the assets of The Retirement Income Program of BorgWarner Diversified
Transmission Products Inc. Muncie Plant (the "Muncie Plan"), a qualified pension
plan as defined by Section 401(a) of the Internal Revenue Code of 1986, as
amended (the "Code"). BorgWarner Diversified Transmission Products Inc., an
affiliate of ours, is the sponsor of the Muncie Plan and we, by virtue of
certain agreements, have the responsibility to determine the nature, timing and
amount of contributions in satisfaction of contribution requirements under the
Employment Retirement Income Security Act of 1974, as amended ("ERISA") and the
Code for the Muncie Plan.  We make contributions from time to time in amounts
that are not less than the minimum amount required under, or more than the
maximum deductible amount permitted by, Section 412 of the Code.

     Unless and until we make additional contributions of stock to satisfy our
ERISA contribution requirements to the Muncie Plan, the shares described herein
are the only shares of our common stock that are or will be held by the selling
stockholder and after they are sold, the selling stockholder will not own any of
our common stock. The shares are held in the custody of The Northern Trust
Company, 50 South LaSalle Street, Chicago, IL 60675, as the trustee for the
selling stockholder under a Trust Agreement made with us July 1, 1981, as
amended from time to time. We currently have ongoing banking and trustee
relationships with The Northern in the ordinary course of business and expect to
continue to have such relationships in the future.

     Except as described herein, neither the selling stockholder nor The
Northern is an affiliate of ours nor have either of them had any other material
relationship with us during the last three years.

PLAN OF DISTRIBUTION

     We are registering the shares on behalf of the selling stockholder. The
selling stockholder will offer and sell the shares to which this prospectus
relates for its own account. We will not receive any proceeds from the sale of
the shares. We will contribute 100,000 shares to the selling stockholder prior
to the effectiveness of the registration statement to satisfy our
contribution requirements under ERISA.

     We have agreed to indemnify the selling stockholder against specified
liabilities under the Securities Act and to pay substantially all of the
expenses incidental to the registration, offering
and sale of the securities to the public other than commissions, fees and
discounts of underwriters, brokers, dealers and agents.

     The selling stockholder may sell the shares of common stock described in
this prospectus directly to purchasers or to or through underwriters,
 broker-dealers or agents, which may act as agents or principals.
As a result, pledgees,
donees, transferees or other successors in interest that receive such shares as
a gift, distribution or other non-sale related transfer may offer shares of the
common stock covered by this prospectus. If any shares covered by this
prospectus qualify for sale pursuant to Rule 144 under the Securities Act of
1933, as amended (the "Securities Act"), the selling stockholder may sell such
shares under Rule 144 rather than pursuant to this prospectus.

     The selling stockholder may sell shares of common stock covered by this
prospectus from time to time in one or more of the following transactions:

  .    on the New York Stock Exchange;
  .    in privately-negotiated transactions, including block sale transactions;
  .    ordinary brokers' transactions, which may include long sales or short
sales effected after the effective date of the registration statement of which
this prospectus is a part;
     .    transactions involving block trades or otherwise on The New York Stock
Exchange;
     .    purchases by brokers, dealers or underwriters as principal and resale
by the purchasers for their own accounts pursuant to this prospectus;
     .    "at the market" to or through market makers or into an existing market
for the shares;
     .    through put or call option transactions relating to or covered by the
shares (whether exchange listed or otherwise); and
     .    any combination of the above methods of sale or any other legally
available means.

The sale price to the public may be:

..    the market price prevailing at the time of sale;
..    a price related to such prevailing market price;
..    at negotiated prices; or
..    such other price as the selling stockholder determines from time to time.

  The selling stockholder shall have the sole and absolute discretion not to
accept any purchase, offer or make any sale of shares if it deems the purchase
price to be unsatisfactory at any particular time.

In effecting sales, brokers or dealers engaged by the selling stockholder
may arrange for other brokers or dealers to participate in the resales. The
selling stockholder also may enter into option or other transactions with
broker-dealers that require the delivery to the broker-dealer of the shares,
which the broker-dealer may resell pursuant to this prospectus. The selling
stockholder may pledge the shares to a broker or dealer, and upon a default, the
broker or dealer may effect sales of the pledged shares pursuant to this
prospectus.

The selling stockholder or its respective pledgees, donees, transferees or
other successors in interest, may also sell their shares directly to market
makers acting as principals or broker-dealers acting as agents for themselves or
their customers. Such broker-dealers may receive compensation in the form of
discounts, concessions or commissions from the selling stockholder or the
purchasers of shares for whom the broker-dealers may act as agents or to whom
they sell as principal or both, which compensation as to a particular
 broker-dealer may be in excess of customary commissions.
Market makers and block
purchasers purchasing the shares will do so for their own account and at their
own risk. It is possible that the selling stockholder will attempt to sell
shares of common stock in block transactions to market makers or other
purchasers at a price per share which may be below the then market price.

The selling stockholder and any underwriters, broker-dealers or agents that
participate in the distribution of shares offered in this prospectus may be
deemed "underwriters" as that term is defined under the Securities Act. The SEC
may deem any commissions received by any underwriter, broker-dealer or agent and
any profit on the resale of the securities sold by them while acting as
principals to be underwriting discounts or commissions under the Securities Act.
Because the selling stockholder may be deemed to be an "underwriter," the
selling stockholder will be subject to the prospectus delivery requirements of
the Securities Act. In addition, any securities covered by this prospectus which
qualify for sale through Rule 144 under the Securities Act may be sold under
Rule 144 rather than through this prospectus. The selling stockholder has
advised us that it has not entered into any agreements, understandings or
arrangements with any underwriters or broker-dealers regarding the sale of the
securities. There is no underwriter or coordinating broker acting in connection
with the proposed sale of shares by the selling stockholder.

         When we are notified by the selling stockholder that any material
arrangement has been entered into with a broker-dealer for the sale of shares
through a block trade, special offering, exchange distribution or secondary
distribution or a purchase by a broker or dealer, a supplement to this
prospectus will be filed, if required, pursuant to Rule 424(b) under the
Securities Act, disclosing (1) the name of each such selling stockholder and of
the participating broker-dealer, (2) the number of shares involved, (3) the
price at which such shares were sold, (4) the commissions paid or discounts or
concessions allowed to such broker-dealer, where applicable, (5) that such
broker-dealer did not conduct any investigation to verify the information set
out or incorporated by reference in this prospectus and (6) other facts material
to the transaction. In addition, upon being notified by the selling stockholder
that a donee, pledgee, transferee or other successor-in-interest intends to sell
more than 500 shares, a supplement to this prospectus will be filed.

 The selling stockholder and any other persons participating in the sale or
distribution of the shares will be subject to the applicable provisions of the
Securities Exchange Act of 1934, as amended, and the rules and regulations under
such Act, including without limitation, Regulation M. These provisions may
restrict certain activities of, and limit the timing of, purchases and sales of
any shares of common stock offered under this prospectus by the selling
stockholder or other persons or entities. Furthermore, under Regulation M,
persons engaged in a distribution of securities are prohibited from
simultaneously engaging in market making and certain other activities with
respect to such securities for a specified period of time prior to the
commencement of such distributions, subject to specified exceptions or
exemptions. All of these limitations may affect the
marketability of the shares.

         The BorgWarner Inc. Employee Benefits Committee (the "Committee") was
established, for, among other things, the purpose of fulfilling the fiduciary
responsibility of establishing the investment policy for the Muncie Plan and the
selling stockholder, as required by Section 401(b) of ERISA. In fulfilling its
ERISA duties, the Committee adopted an investment policy that the selling
stockholder should not hold any BorgWarner shares for an extended period of
time. Accordingly, we expect that when the selling stockholder receives the
contribution of shares from us, it will sell them to the public shortly
thereafter. There can be no assurance that the selling stockholder will sell any
or all of the shares of common stock offered by it hereunder.

LEGAL MATTERS

 The validity of the common stock offered pursuant to this prospectus will
be passed upon for us by McGuireWoods LLP, Chicago, Illinois.

Item 15.  Indemnification of Directors and Officers

Section 145 of the Delaware General Corporation Law ("DGCL") provides as
follows:

         A corporation may indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation) by reason of the
fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interest of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

         A corporation may indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the corporation to procure a judgment in its favor by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation, as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorney's fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation and except that no indemnification shall be made in respect to any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Court of
Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Court of Chancery or such other court
shall deem proper.

         BorgWarner Inc.'s restated certificate of incorporation provides for
indemnification of its directors and officers to the fullest extent permitted by
the DGCL, and allows BorgWarner Inc. to advance or reimburse litigation expenses
upon submission by the director, officer or employee of an undertaking to repay
such advances or reimbursements if it is ultimately determined that
indemnification is not available to such director or officer.

         As permitted by Section 102 of the DGCL, BorgWarner Inc.'s restated
certificate of incorporation provides that no director shall be liable to
BorgWarner Inc. or its stockholders for monetary damages for breach of fiduciary
duty as a director other than (i) for breaches of the director's duty of loyalty
to BorgWarner Inc. and its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) for the unlawful payment of dividends or unlawful stock purchases or
redemptions under Section 174 of the DGCL, or (iv) for any transaction from
which the director derived an improper personal benefit.

 The registrant maintains directors and officers liability insurance for the
benefit of its directors and officers.

         For information concerning the registrant's undertaking to submit to
adjudication the issue of indemnification for violation of the securities laws,
see Item 17 hereof.

Item 17. Undertakings

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post
effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act
of 1933, as amended (the "Securities Act");

(ii) To reflect in the prospectus any facts or events arising after the
effective date of the registration statement (or the most recent post-effective
amendment thereof) which, individually or in the aggregate, represent a
fundamental change in the information set forth in the registration statement.
Notwithstanding the foregoing, any increase or decrease in volume of securities
offered (if the total dollar value of securities offered would not exceed that
which was registered) and any deviation from the low or high end of the
estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20 percent change in the
maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement; and

(iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement;

provided, however, that paragraphs (1)(i) and (1)(ii) above do not apply if
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant pursuant to
Section 13 or Section 15(d) of the Securities Exchange Act of 1934 (the
"Exchange Act") that are incorporated by reference in the registration
statement;

(2) That, for the purpose of determining any liability under the Securities Act,
each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

(3) To remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.

The undersigned registrant hereby further undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act may
be permitted to directors, officers and controlling persons of the registrant
pursuant to the provisions set forth in response to Item 15, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question of whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
                                    SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, as amended,
BorgWarner Inc. certifies that it has reasonable grounds to believe that it
meets all of the requirements for filing on Form S-3 and has duly caused this
Amendment to Registration Statement  to be signed on its behalf by the
undersigned, thereunto duly authorized in the City of Chicago, State of
Illinois, on September 11 , 2002.
