Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The accompanying unaudited Condensed Consolidated Financial Statements of BorgWarner Inc. and Consolidated Subsidiaries (the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes necessary for a comprehensive presentation of financial position, results of operations and cash flow activity required by GAAP for complete financial statements. In the opinion of management, all normal recurring adjustments necessary for a fair statement of results have been included. Certain prior period amounts have been reclassified to conform to the current period presentation. Operating results for the three and six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. The balance sheet as of December 31, 2022 was derived from the audited financial statements as of that date. For further information, refer to the Consolidated Financial Statements and Footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. Management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and accompanying notes, as well as the amounts of revenues and expenses reported during the periods covered by those financial statements and accompanying notes. Actual results could differ from these estimates. On July 3, 2023, BorgWarner completed the previously announced spin-off (“Spin-Off”) of its Fuel Systems and Aftermarket segments in a transaction intended to qualify as tax free to the Company’s stockholders for U.S. federal income tax purposes, which was accomplished by the distribution of 100% of the outstanding common stock of PHINIA, Inc. (“PHINIA”) to holders of record of common stock of the Company on a pro-rata basis. Each holder of record of common stock of the Company received one share of PHINIA common stock for every five shares of common stock of the Company held on June 23, 2023, the record date for the distribution (“Distribution Date”). In lieu of fractional shares of PHINIA, shareholders of the Company received cash. PHINIA is an independent public company trading under the symbol “PHIN” on the New York Stock Exchange. The historical results of operations and the financial position of PHINIA are included in these Condensed Consolidated Financial Statements. Starting in the third quarter of 2023, the Company will no longer consolidate its Fuel Systems and Aftermarket segments, and results for those segments for all periods prior to the Spin-Off will be reflected as discontinued operations. The Spin-Off has the potential to impact the allocation of profit across jurisdictions for tax purposes as well as various tax structuring actions and strategies. Evidence could become available in subsequent quarters that may require the Company to adjust its tax positions including those related to valuation allowances. In connection with the Spin-Off, the Company entered into several agreements with PHINIA on or prior to the Distribution Date that, among other things, provide a framework for the Company’s relationship with PHINIA after the Spin-Off, including a separation and distribution agreement, an employee matters agreement, a tax matters agreement, an intellectual property cross-license agreement and a transition service agreement through which the Company and PHINIA will continue to provide certain services to each other following the Spin-Off.

Accounting Standards Update and Change in Accounting Principle [Abstract]
NEW ACCOUNTING PRONOUNCEMENTS	NEW ACCOUNTING PRONOUNCEMENTSIn October 2021, the FASB issued ASU No. 2021-08, “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers.” It requires entities to apply ASC Topic 606, “Revenue from Contracts with Customers,” to recognize and measure contract assets and contract liabilities in a business combination. The amendments improve comparability after the business combination by providing consistent recognition and measurement guidance for revenue contracts with customers acquired in a business combination and revenue contracts with customers not acquired in a business combination. This guidance is effective for interim and annual reporting periods beginning after December 15, 2022. The Company adopted this guidance prospectively as of January 1, 2023, and there was no impact on the Condensed Consolidated Financial Statements.

Business Combination and Asset Acquisition [Abstract]
ACQUISITIONS	ACQUISITIONS In accordance with ASC Topic 805, “Business Combinations,” acquisitions are recorded using the acquisition method of accounting. The Company recognizes and measures the acquisition date fair value of the identifiable assets acquired, liabilities assumed, and any non-controlling interest using a range of methodologies as indicated by generally accepted valuation practices. Various valuation techniques are used to determine the fair value of intangible assets, with the primary techniques being forms of the income approach, specifically the relief-from-royalty and multi-period excess earnings valuation methods. Under these valuation approaches, the Company is required to make estimates and assumptions from a market participant perspective and may include revenue growth rates, estimated earnings, royalty rates, obsolescence factors, contributory asset charges, customer attrition and discount rates. Due to the insignificant size of the 2023 and 2022 acquisitions, both individually and in the aggregate, relative to the Company, supplemental pro forma financial information for the current and prior reporting periods is not provided. Eldor Corporation’s Electric Hybrid Systems Business On June 19, 2023, the Company announced that it had entered into a share purchase agreement to acquire the Electric Hybrid Systems business segment of Eldor Corporation (“Eldor”), which is headquartered in Italy. The purchase price due at closing is €75 million ($82 million), with up to €175 million ($191 million) in contingent payments that could be paid over the next 2 years. The acquisition is expected to complement the Company’s existing ePropulsion product portfolio by enhancing the Company’s engineering capabilities. The transaction is subject to satisfaction of customary closing conditions and is expected to close in the third quarter of 2023. Hubei Surpass Sun Electric Charging Business On March 1, 2023, the Company completed its acquisition of 100% of the electric vehicle solution, smart grid and smart energy businesses (“SSE”) of Hubei Surpass Sun Electric, pursuant to an Equity Transfer Agreement. The acquisition complements the Company’s existing European and North American charging footprint by adding a presence in China. The total consideration was ¥288 million ($42 million), including ¥268 million ($39 million) of base purchase price and ¥20 million ($3 million) of estimated earn-out payments. The Company paid ¥207 million ($30 million) of base purchase price in the six months ended June 30, 2023. Of the remaining ¥61 million ($9 million) of base purchase price, ¥41 million ($6 million) is payable by September 30, 2023 and is recorded in Other current liabilities in the Company’s Condensed Consolidated Balance Sheet as of June 30, 2023. The remaining ¥20 million ($3 million) of base purchase price is payable before March 31, 2025 and is recorded in Other non-current liabilities in the Company’s Condensed Consolidated Balance Sheet as of June 30, 2023. Pursuant to the agreement, the Company’s obligation to remit up to ¥103 million ($15 million) of earn-out payments is contingent upon the achievement of certain revenue and pre-tax profit margin targets in 2023 and 2024 as well as the retention of key employees during the same time period. As of June 30, 2023, the Company’s estimate of the earn-out payments was approximately ¥20 million ($3 million), of which half is recorded in Other current liabilities and half is recorded in Other non-current liabilities in the Company’s Condensed Consolidated Balance Sheet. The purchase price was allocated on a provisional basis as of March 1, 2023. Assets acquired and liabilities assumed were recorded at estimated fair values based on management’s estimates, available information, and supportable assumptions that management considered reasonable. Certain estimated values for the acquisition, including goodwill, tangible, and intangible assets and deferred taxes, are not yet finalized, and the provisional purchase price allocations are subject to change as the Company completes its analysis of the fair value at the date of acquisition. The final valuation of assets acquired and liabilities assumed may be materially different than the estimated values shown below. The estimated fair values of assets acquired and liabilities assumed as of March 1, 2023 were assets of $50 million, including goodwill and intangibles of $16 million, and liabilities of $8 million. Any excess of the purchase price over the estimated fair value of net assets was recognized as goodwill. Goodwill of $12 million was recorded within the Company’s Air Management segment. The goodwill consists of the Company’s expected future economic benefits that will be realized from expanding the Company’s electric vehicle portfolio as electric vehicle production continues to increase. The goodwill is not expected to be deductible for tax purposes in China. In connection with the acquisition, the Company preliminarily recorded $4 million for intangible assets, primarily for customer relationships and developed technology. The provisional fair values of the identifiable intangible assets were valued using the market approach. The impact of the SSE acquisition on net sales and net earnings was immaterial for the three and six months ended June 30, 2023. Drivetek AG On December 1, 2022, the Company completed its acquisition of 100% of Drivetek AG (“Drivetek”), an engineering and product development company located in Switzerland. This acquisition strengthens the Company’s power electronics capabilities in auxiliary inverters, which the Company expects will accelerate the growth of its High Voltage eFan business. The Company paid ₣27 million ($29 million) at closing, and up to ₣10 million ($10 million) could be paid in the form of contingent earn-out payments over the three years following closing. The earn-out payments are contingent upon achievement of estimated future sales targets associated with newly awarded business and future turnover rate targets. As of June 30, 2023, the Company’s estimate of the earn-out payments was approximately ₣10 million ($11 million), which is recorded in Other non-current liabilities in the Company’s Condensed Consolidated Balance Sheet. The purchase price was allocated on a preliminary basis as of December 1, 2022. Assets acquired and liabilities assumed were recorded at estimated fair values based on management’s estimates, available information, and supportable assumptions that management considered reasonable. Certain estimated values for the acquisition, including goodwill, tangible and intangible assets and deferred taxes, are not yet finalized, and the preliminary purchase price allocations are subject to change as the Company completes its analysis of the fair value at the date of acquisition. The final valuation of assets acquired and liabilities assumed may be materially different from the estimated values shown below. The estimated fair values of assets acquired and liabilities assumed as of December 1, 2022 were assets of $49 million, including goodwill and intangibles of $40 million, and liabilities of $10 million. Any excess of the purchase price over the estimated fair value of net assets was recognized as goodwill. Goodwill of $22 million was recorded within the Company’s Air Management segment. The goodwill consists of the Company’s expected future economic benefits that will be realized from expanding the Company’s electric vehicle portfolio as electric vehicle production continues to increase. The goodwill is not expected to be deductible for tax purposes in Switzerland. The following table summarizes the other intangible assets acquired: (in millions) Estimated Life Estimated Fair Value Developed technology 8 years $ 11 Customer relationships 12 years 7 Total other intangible assets $ 18 Identifiable intangible assets were valued using the market approach. The impact of the Drivetek acquisition on net sales and net earnings was immaterial for the three and six months ended June 30, 2023. Rhombus Energy Solutions On July 29, 2022, the Company completed its acquisition of 100% of Rhombus Energy Solutions (“Rhombus”), a provider of charging solutions in the North American market, pursuant to the terms of an Agreement and Plan of Merger (the “Agreement”). The acquisition complements the Company’s existing European charging footprint to accelerate organic growth and adds North American regional presence to its charging business. The Company paid $131 million at closing. Pursuant to the Agreement, the Company is obligated to remit up to $30 million of earn-out payments, payable in 2025, contingent upon achievement of certain sales dollars, sales volume, and gross margin targets. The Company’s current estimates indicate that the minimum thresholds for these earn-out targets will not be achieved; thus, no amount for the earn-out payments has been included in the purchase consideration or in the Company’s Condensed Consolidated Balance Sheet. Additionally, pursuant to the Agreement, the Company is obligated to remit up to $25 million over the three years following closing in key employee retention-related payments, which include certain performance targets. The amounts will be accounted for as post-combination expense. The Company finalized its valuation of the assets and liabilities of the Rhombus acquisition during the second quarter of 2023. Any excess of the purchase price over the estimated fair value of net assets was recognized as goodwill. Goodwill of $104 million was recorded within the Company’s Air Management segment. The goodwill consists of the Company’s expected future economic benefits that will be realized from expanding the Company’s electric vehicle portfolio as electric vehicle production continues to increase. The goodwill is not expected to be deductible for tax purposes. The following table summarizes the other intangible assets acquired: (in millions) Estimated Life Estimated Fair Value Developed technology 13 years $ 22 Customer relationships 8 years 5 Total other intangible assets $ 27 Identifiable intangible assets were valued using the income approach. The impact of the Rhombus acquisition on net sales and net earnings was immaterial for the three and six months ended June 30, 2023. Santroll Automotive Components On March 31, 2022, the Company completed its acquisition of 100% of Santroll Automotive Components (“Santroll”), a carve-out of Santroll Electric Auto’s eMotor business, pursuant to the terms of an Equity Transfer Agreement (“ETA”). The acquisition is expected to strengthen the Company’s vertical integration, scale and portfolio breadth in light vehicle eMotors while allowing for increased speed to market. The total final consideration was $192 million, including approximately ¥1.0 billion ($152 million) of base purchase price and ¥0.25 billion ($40 million) of originally estimated earn-out payments. The Company paid approximately ¥1.0 billion ($157 million) of base purchase price in the year ended December 31, 2022 and no longer expects to recapture a previously anticipated $5 million of post-closing adjustments, which has been recorded in other operating expense. Pursuant to the ETA, the obligation of the Company to remit up to ¥0.3 billion (approximately $47 million) of earn-out payments was contingent upon achievement of certain sales volume targets and certain estimated future volume targets associated with newly awarded business. During the three months ended June 30, 2023, the Company paid approximately ¥0.2 billion ($24 million) to settle the remaining earn-out liability and related adjustments. The Company finalized its valuation of the assets and liabilities of the Santroll acquisition during the first quarter of 2023. Any excess of the purchase price over the estimated fair value of net assets was recognized as goodwill. Goodwill of $112 million was recorded within the Company’s ePropulsion segment. The goodwill consists of the Company’s expected future economic benefits that will arise from future product sales and the added capabilities from vertical integration of eMotors. The goodwill is not expected to be deductible for tax purposes in China. The following table summarizes the other intangible assets acquired: (in millions) Estimated Life Estimated Fair Value Customer relationships 12 years $ 62 Manufacturing processes (know-how) 10 years 25 Total other intangible assets $ 87 Identifiable intangible assets were valued using the income approach.

REVENUE FROM CONTRACTS WITH CUS

REVENUE FROM CONTRACTS WITH CUSTOMERS	6 Months Ended

Revenue from Contract with Customer [Abstract]
REVENUE FROM CONTRACTS WITH CUSTOMERS	REVENUE FROM CONTRACTS WITH CUSTOMERS The Company manufactures and sells products, primarily to OEMs of light vehicles and, to a lesser extent, to other OEMs of commercial vehicles and off-highway vehicles, to certain tier one vehicle systems suppliers and into the aftermarket. The Company’s payment terms are based on customary business practices and vary by customer type and products offered. The Company evaluated the terms of its arrangements and determined that they do not contain significant financing components. Generally, revenue is recognized upon shipment or delivery; however, a limited number of the Company’s customer arrangements for its highly customized products with no alternative use provide the Company with the right to payment during the production process. As a result, for these limited arrangements, revenue is recognized as goods are produced and control transfers to the customer using the input cost-to-cost method. The Company recorded a contract asset of $15 million and $16 million at June 30, 2023 and December 31, 2022, respectively, for these arrangements. These amounts are reflected in Prepayments and other current assets in the Company’s Condensed Consolidated Balance Sheets. In limited instances, certain customers have provided payments in advance of receiving related products, typically at the onset of an arrangement prior to the beginning of production. These contract liabilities are reflected as Other current liabilities in the Condensed Consolidated Balance Sheets and were $22 million at June 30, 2023 and $16 million at December 31, 2022. These amounts are reflected as revenue over the term of the arrangement (typically 3 to 7 years) as the underlying products are shipped and represent the Company’s remaining performance obligations as of the end of the period. The Company continually seeks business development opportunities and, at times, provides customer incentives for new program awards. When the Company determines that the payments are incremental and incurred only if the new business is obtained and expects to recover these amounts from the customer over the term of the new business arrangement, the Company capitalizes these amounts. As of June 30, 2023 and December 31, 2022, the Company recorded customer incentive payments of $28 million and $34 million, respectively, in Prepayments and other current assets, and $85 million and $99 million, respectively, in Other non-current assets in the Condensed Consolidated Balance Sheets. The following tables represent a disaggregation of revenue from contracts with customers by reportable segment and region. The balances for the three and six months ended June 30, 2022 have been recast for a change in reportable segments that was made during the first quarter of 2023.

Restructuring and Related Activities [Abstract]
RESTRUCTURING	RESTRUCTURING The Company’s restructuring activities are undertaken, as necessary, to execute management’s strategy and streamline operations, consolidate and take advantage of available capacity and resources, and ultimately achieve net cost reductions. Restructuring activities include efforts to integrate and rationalize the Company’s business and to relocate operations to best-cost locations. The Company’s restructuring expenses consist primarily of employee termination benefits (principally severance and/or termination benefits) and other costs, which are primarily professional fees and costs related to facility closures and exits.

Foundational products include all products utilized on internal combustion engines plus those same products and components that are also included in hybrid powertrains. During the three and six months ended June 30, 2023, the Company recorded $9 million and $12 million of restructuring costs related to this plan, respectively. 2020 Structural Costs Plan In 2020, the Company announced a $300 million restructuring plan to address its structural costs. During the three and six months ended June 30, 2023, the Company recorded $3 million and $7 million of restructuring charges related to this plan, respectively. During the three and six months ended June 30, 2022, the Company recorded $10 million and $23 million of restructuring charges related to this plan, respectively. Cumulatively, the Company has incurred $294 million of restructuring charges related to this plan. The actions under this plan are complete. 2019 Legacy Delphi Technologies Plan In 2019, legacy Delphi Technologies PLC (“Delphi Technologies”) announced a restructuring plan to reshape and realign its global technical center footprint and reduce salaried and contract staff. The Company continued actions under this plan following its October 1, 2020 acquisition of Delphi Technologies and has recorded cumulative charges of $67 million since October 1, 2020, including approximately $4 million in restructuring charges during the six months ended June 30, 2022. The actions under this plan are complete. The following provides details of restructuring expense incurred by the Company’s reportable segments during the three and six months ended June 30, 2023 and 2022, related to the plans and actions discussed above: Air Management 2023 Structural Costs Plan • During the three and six months ended June 30, 2023, the segment recorded $9 million and $12 million of restructuring costs under this plan, primarily related to employee severance. 2020 Structural Costs Plan • During the three and six months ended June 30, 2022, the segment recorded $7 million and $13 million, respectively, of restructuring costs under this plan. This primarily related to $8 million during the six months ended June 30, 2022 for a voluntary termination program pursuant to which approximately 36 employees accepted termination packages in 2022. Drivetrain & Battery Systems 2020 Structural Costs Plan • During the three and six months ended June 30, 2022, the segment recorded $2 million and $9 million of restructuring costs, primarily related to severance costs associated with the announced closure of a technical center in Europe affecting approximately 80 employees. ePropulsion 2020 Structural Costs Plan • During the three and six months ended June 30, 2022, the segment recorded $1 million of restructuring costs under this plan, primarily related to legal fees, equipment moves, and validation and testing costs. Fuel Systems 2020 Structural Costs Plan • During the three and six months ended June 30, 2023, the segment recorded $2 million and $6 million of restructuring costs under this plan, primarily related to employee severance. 2019 Legacy Delphi Technologies Plan • During the three and six months ended June 30, 2022, the segment recorded $4 million and $5 million, respectively, of restructuring costs under this plan, primarily related to employee severance and equipment moves. Aftermarket 2020 Structural Costs Plan • During the six months ended June 30, 2023, the segment recorded $1 million of restructuring costs under this plan, primarily related to employee severance. Estimates of restructuring expense are based on information available at the time such charges are recorded. Due to the inherent uncertainty involved in estimating restructuring expenses, actual amounts paid for such activities may differ from amounts initially recorded. Accordingly, the Company may record revisions of previous estimates by adjusting previously established accruals. The Company continues to evaluate different options across its operations to reduce existing structural costs over the next few years. The Company will recognize restructuring expense associated with any future actions at the time they are approved and become probable or are incurred. Any future actions could result in significant restructuring expense.

Research and Development [Abstract]
RESEARCH AND DEVELOPMENT COSTS	RESEARCH AND DEVELOPMENT COSTS The Company’s net Research & Development (“R&D”) expenditures are included in Selling, general and administrative expenses of the Condensed Consolidated Statements of Operations. Customer reimbursements are netted against gross R&D expenditures as they are considered a recovery of cost. Customer reimbursements for prototypes are recorded net of prototype costs based on customer contracts, typically either when the prototype is shipped or when it is accepted by the customer. Customer reimbursements for engineering services are recorded when performance obligations are satisfied in accordance with the contract. Financial risks and rewards transfer upon shipment, acceptance of a prototype component by the customer or upon completion of the performance obligation, as stated in the respective customer agreement. The Company has contracts with several customers relating to R&D activities that the Company performs at the Company’s various R&D locations. The following table presents the Company’s gross and net expenditures on R&D activities: Three Months Ended June 30, Six Months Ended June 30, ( in millions ) 2023 2022 2023 2022 Gross R&D expenditures $ 259 $ 234 $ 503 $ 466 Customer reimbursements (51) (27) (102) (68) Net R&D expenditures $ 208 $ 207 $ 401 $ 398

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company’s provision for income taxes is based upon an estimated annual tax rate for the year applied to federal, state and foreign income. On a quarterly basis, the annual effective tax rate is adjusted, as appropriate, based upon changed facts and circumstances, if any, as compared to those forecasted at the beginning of the fiscal year and each interim period thereafter. The Company’s effective tax rate for the three months ended June 30, 2023 and 2022 was 32% and 20%, respectively. During the three months ended June 30, 2023, a discrete tax expense of approximately $20 million was recorded in relation to the Spin-Off and a discrete tax benefit of $11 million was recorded relating to various immaterial tax adjustments. During the three months ended June 30, 2022, a discrete tax benefit of $8 million was recorded relating to various immaterial tax adjustments. The Company’s effective tax rate for the six months ended June 30, 2023 and 2022 was 30% and 25%, respectively. During the six months ended June 30, 2023, a discrete tax expense of approximately $20 million was recorded in relation to the Spin-Off, a discrete tax benefit of approximately $14 million was recorded related to the resolution of tax audits, a $10 million discrete tax expense was recorded for the impact of enacted tax law changes and a discrete tax benefit of $10 million was recorded related to various immaterial tax adjustments. During the six months ended June 30, 2022, a discrete tax benefit of $8 million was recorded relating to various immaterial tax adjustments. The annual effective tax rates differ from the U.S. statutory rate primarily due to foreign rates that vary from those in the U.S., jurisdictions with pretax losses for which no tax benefit could be realized, U.S. taxes on foreign earnings, the realization of certain business tax credits (including foreign tax credits), and permanent differences between book and tax treatment for certain items (including the Foreign-Derived Intangible Income (“FDII”) deduction and the enhanced deduction of research and development expenses in certain jurisdictions). The Company estimates that it is reasonably possible there could be a decrease of approximately $98 million in unrecognized tax benefits and interest in the next 12 months related to the conclusion of tax audits and the lapse of statutes of limitations subsequent to the reporting period in certain taxing jurisdictions.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND OTHER INTANGIBLES	GOODWILL AND OTHER INTANGIBLES During the fourth quarter of each year, the Company assesses its goodwill and indefinite-lived intangible assets assigned to each of its reporting units. In addition, the Company may test goodwill in between annual test dates if an event occurs or circumstances change that could more-likely-than-not reduce the fair value of a reporting unit below its carrying value. No events or circumstances were noted in the first six months of 2023 requiring additional assessment or testing. Future changes in the judgments, assumptions and estimates from those used in acquisition-related valuations and goodwill impairment testing, including discount rates or future operating results and related cash flow projections, could result in significantly different estimates of the fair values in the future. An increase in discount rates, a reduction in projected cash flows or a combination of the two could lead to a reduction in the estimated fair values, which may result in impairment charges that could materially affect the Company’s financial statements in any given year. A summary of the changes in the carrying amount of goodwill are as follows: (in millions) Air Management Drivetrain & Battery Systems ePropulsion Aftermarket Fuel Systems Total Gross goodwill balance, December 31, 2022 $ 1,566 $ 1,434 $ 480 $ 374 $ 45 $ 3,899 Accumulated impairment losses, December 31, 2022 (502) — — — — (502) Net goodwill balance, December 31, 2022* $ 1,064 $ 1,434 $ 480 $ 374 $ 45 $ 3,397 Goodwill during the period: Acquisitions 12 — — — — 12 Other, primarily translation adjustment 5 12 (23) 1 — (5) Ending balance, June 30, 2023 $ 1,081 $ 1,446 $ 457 $ 375 $ 45 $ 3,404 __________________________________ * The December 31, 2022 balances have been recast for a change in reportable segments that was made during the first quarter of 2023.

The fair value step-up was calculated based on observable market data and is amortized as a reduction to interest expense over the remaining life of the instrument using the effective interest method. The Company may utilize uncommitted lines of credit for short-term working capital requirements. As of June 30, 2023 and December 31, 2022, the Company had $62 million and $58 million, respectively, in borrowings under these facilities, which are classified in Notes payable and other short-term debt on the Condensed Consolidated Balance Sheets. The following table provides details on Interest expense, net included in the Condensed Consolidated Statements of Operations: Three Months Ended June 30, Six Months Ended June 30, (in millions) 2023 2022 2023 2022 Interest expense $ 21 $ 21 $ 41 $ 40 Interest income (9) (6) (19) (10) Interest expense, net $ 12 $ 15 $ 22 $ 30 The Company has a $2 billion multi-currency revolving credit facility that allows the Company to increase the facility by $1 billion with bank group approval. This facility matures in March 2025. The credit agreement contains customary events of default and one key financial covenant, which is a debt-to-EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) ratio. The Company was in compliance with the financial covenant at June 30, 2023. At June 30, 2023 and December 31, 2022, the Company had no outstanding borrowings under this facility. The Company’s commercial paper program allows the Company to issue up to $2 billion of short-term, unsecured commercial paper notes under the limits of its multi-currency revolving credit facility. Under this program, the Company may issue notes from time to time and use the proceeds for general corporate purposes. The Company had no outstanding borrowings under this program as of June 30, 2023 and December 31, 2022. The total current combined borrowing capacity under the multi-currency revolving credit facility and commercial paper program cannot exceed $2 billion. As of June 30, 2023 and December 31, 2022, the estimated fair values of the Company’s senior unsecured notes totaled $3,649 million and $3,553 million, respectively. The estimated fair values were $485 million lower than their carrying value at June 30, 2023 and $570 million lower than their carrying value at December 31, 2022. Fair market values of the senior unsecured notes are developed using observable values for similar debt instruments, which are considered Level 2 inputs as defined by ASC Topic 820. The carrying values of the Company's multi-currency revolving credit facility, commercial paper program and other debt facilities approximate fair value. The fair value estimates do not necessarily reflect the values the Company could realize in the current markets. The Company had outstanding letters of credit of $37 million and $38 million at June 30, 2023 and December 31, 2022, respectively. The letters of credit typically act as guarantees of payment to certain third parties in accordance with specified terms and conditions.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	6 Months Ended
	Jun. 30, 2023
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS ASC Topic 820 emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering market participant assumptions in fair value measurements, ASC Topic 820 establishes a fair value hierarchy, which prioritizes the inputs used in measuring fair values as follows: Level 1: Observable inputs such as quoted prices for identical assets or liabilities in active markets; Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and Level 3: Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions. Assets and liabilities measured at fair value are based on one or more of the following three valuation techniques noted in ASC Topic 820: A. Market approach: Prices and other relevant information generated by market transactions involving identical or comparable assets, liabilities or a group of assets or liabilities, such as a business. B. Cost approach: Amount that would be required to replace the service capacity of an asset (replacement cost). C. Income approach: Techniques to convert future amounts to a single present amount based upon market expectations (including present value techniques, option-pricing and excess earnings models). The following tables classify assets and liabilities measured at fair value on a recurring basis as of June 30, 2023 and December 31, 2022: Basis of fair value measurements (in millions) Balance at June 30, 2023 Quoted prices in active markets for identical items Significant other observable inputs Significant unobservable inputs Valuation technique Assets measured at NAV 1 Assets: Investment in debt securities $ 386 $ — $ 386 $ — A $ — Investment in equity securities $ 28 $ — $ — $ — — $ 28 Foreign currency contracts $ 54 $ — $ 54 $ — A $ — Net investment hedge contracts $ 38 $ — $ 38 $ — A $ — Liabilities: Current earn-out liabilities $ 2 $ — $ — $ 2 C $ — Non-current earn-out liabilities $ 13 $ — $ — $ 13 C $ — Foreign currency contracts $ 8 $ — $ 8 $ — A $ — Basis of fair value measurements (in millions) Balance at Quoted prices in active markets for identical items Significant other observable inputs Significant unobservable inputs Valuation Assets measured at NAV 1 Assets: Current earn-out receivable $ 9 $ — $ — $ 9 C $ — Investment in debt securities $ 455 $ — $ 455 $ — A $ — Investment in equity securities $ 29 $ — $ — $ — — $ 29 Foreign currency contracts $ 18 $ — $ 18 $ — A $ — Net investment hedge contracts $ 68 $ — $ 68 $ — A $ — Liabilities: Current earn-out liability $ 21 $ — $ — $ 21 C $ — Non-current earn-out liability $ 10 $ — $ — $ 10 C $ — Foreign currency contracts $ 11 $ — $ 11 $ — A $ — Net investment hedge contracts $ 1 $ — $ 1 $ — A $ — _____________________________

FINANCIAL INSTRUMENTS

FINANCIAL INSTRUMENTS	6 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
FINANCIAL INSTRUMENTS	FINANCIAL INSTRUMENTS The Company’s financial instruments include cash and cash equivalents, marketable securities and accounts receivable. Due to the short-term nature of these instruments, their book value approximates their fair value. The Company’s financial instruments may also include long-term debt, investments in equity securities, interest rate and cross-currency swaps, commodity derivative contracts and foreign currency derivative contracts. All derivative contracts are placed with counterparties that have an S&P, or equivalent, investment grade credit rating at the time of the contracts’ placement. An adjustment for non-performance risk is considered in the estimate of fair value in derivative assets based on the counterparty credit default swap (“CDS”) rate. When the Company is in a net derivative liability position, the non-performance risk adjustment is based on its CDS rate. At June 30, 2023 and December 31, 2022, the Company had no derivative contracts that contained credit-risk-related contingent features. The Company, at times, uses certain commodity derivative contracts to protect against commodity price changes related to forecasted raw material and component purchases. At June 30, 2023 and December 31, 2022, the Company had no material commodity derivative contracts. The Company manages its interest rate risk by balancing its exposure to fixed and variable rates while attempting to optimize its interest costs. The Company, at times, selectively uses interest rate swaps and options to reduce market value risk associated with changes in interest rates (fair value hedges and cash flow hedges). At June 30, 2023 and December 31, 2022, the Company had no outstanding interest rate swaps or options. The Company uses foreign currency forward and option contracts to protect against exchange rate movements for forecasted cash flows, including capital expenditures, purchases, operating expenses or sales transactions designated in currencies other than the functional currency of the operating unit. In addition, the Company uses foreign currency forward contracts to hedge exposure associated with its net investment in certain foreign operations (net investment hedges). Foreign currency derivative contracts require the Company, at a future date, to either buy or sell foreign currency in exchange for the operating units’ local currency.

CONTINGENCIES

CONTINGENCIES	6 Months Ended

Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES	CONTINGENCIES In the normal course of business, the Company is party to various commercial and legal claims, actions and complaints, including matters involving warranty claims, intellectual property claims, governmental investigations and related proceedings, general liability and other risks. It is not possible to predict with certainty whether or not the Company will ultimately be successful in any of these commercial and legal matters or, if not, what the impact might be. The Company’s management does not believe that adverse outcomes in any of these commercial and legal claims, actions and complaints are reasonably likely to have a material adverse effect on the Company’s results of operations, financial position or cash flows. An adverse outcome could, nonetheless, be material to the results of operations or cash flows. Environmental The Company and certain of its 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 (“PRPs”) at various hazardous waste disposal sites under the Comprehensive Environmental Response, Compensation and Liability Act (“Superfund”) and equivalent state laws and, as such, may be presently liable for the cost of clean-up and other remedial activities at 21 and 26 such sites as of June 30, 2023 and December 31, 2022, respectively. Responsibility for clean-up and other remedial activities at a Superfund site is typically shared among PRPs based on an allocation formula. The Company believes that none of these matters, individually or in the aggregate, will have a material adverse effect on its results of operations, financial position or cash flows. Generally, this is because either the estimates of the maximum potential liability at a site are not material or the liability will be shared with other PRPs, although no assurance can be given with respect to the ultimate outcome of any such matter. The Company had an accrual for environmental liabilities of $7 million as of both June 30, 2023 and December 31, 2022, included in Other current and Other non-current liabilities in the Condensed Consolidated Balance Sheets. As of June 30, 2023, this accrual, which relates to seven of the sites, is based on information available to the Company (which, in most cases, includes an estimate of allocation of liability among PRPs; the probability that other PRPs, many of which are large, solvent public companies, will fully pay the cost apportioned to them; currently available information from PRPs and/or federal or state environmental agencies concerning the scope of contamination and estimated remediation and consulting costs; and remediation alternatives). Clean-up and other remedial activities are complete or nearing completion at the other 14 sites, for which there was no accrual as of June 30, 2023.

EARNINGS PER SHARE

EARNINGS PER SHARE	6 Months Ended

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE The Company presents both basic and diluted earnings per share of common stock (“EPS”) amounts. Basic EPS is calculated by dividing net earnings attributable to BorgWarner Inc. by the weighted average shares of common stock outstanding during the reporting period. Diluted EPS is calculated by dividing net earnings attributable to BorgWarner Inc. by the weighted average shares of common stock and common stock equivalents outstanding during the reporting period. The dilutive impact of stock-based compensation is calculated using the treasury stock method. The treasury stock method assumes that the Company uses the assumed proceeds from the exercise of awards to repurchase common stock at the average market price during the period. The assumed proceeds under the treasury stock method include the purchase price that the grantee will pay in the future and compensation cost for future service that the Company has not yet recognized. The dilutive effects of performance-based stock awards are included in the computation of diluted earnings per share at the level the related performance criteria are met through the respective balance sheet date. There were 0.9 million performance share units excluded from the computation of the diluted earnings for both the three months ended June 30, 2023 and 2022, respectively. There were 0.7 million and 1.0 million performance share units excluded from the computation of the diluted earnings for the six months ended June 30, 2023 and 2022, respectively. These units were excluded because the related performance criteria had not been met as of the balance sheet dates. The following table reconciles the numerators and denominators used to calculate basic and diluted earnings per share of common stock: Three Months Ended June 30, Six Months Ended June 30, (in millions, except per share amounts) 2023 2022 2023 2022 Basic earnings per share: Net earnings attributable to BorgWarner Inc. $ 204 $ 216 $ 421 $ 416 Weighted average shares of common stock outstanding 233.4 236.9 233.1 237.6 Basic earnings per share of common stock $ 0.87 $ 0.91 $ 1.81 $ 1.75 Diluted earnings per share: Net earnings attributable to BorgWarner Inc. $ 204 $ 216 $ 421 $ 416 Weighted average shares of common stock outstanding 233.4 236.9 233.1 237.6 Effect of stock-based compensation 1.0 1.1 1.2 0.9 Weighted average shares of common stock outstanding including dilutive shares 234.4 238.0 234.3 238.5 Diluted earnings per share of common stock $ 0.87 $ 0.91 $ 1.80 $ 1.74

Segment Reporting [Abstract]
REPORTABLE SEGMENTS AND RELATED INFORMATION	REPORTABLE SEGMENTS AND RELATED INFORMATION The Company’s business is aggregated into five reportable segments: Air Management, Drivetrain & Battery Systems, Fuel Systems, ePropulsion and Aftermarket. These segments are strategic business groups that are managed separately as each represents a specific grouping of related automotive components and systems. In the first quarter of 2023, the Company elected to disaggregate the former e-Propulsion & Drivetrain reportable segment into two separate reportable segments of Drivetrain & Battery Systems and ePropulsion. The Drivetrain & Battery Systems segment’s technologies include battery management systems and control modules, software, friction and mechanical products for automatic transmissions and torque-management products. The ePropulsion segment primarily includes rotating electrical components, power electronics, inverters and electric motors. In the first quarter of 2022, the Company announced that the Americas starter and alternator business, previously reported in its former e-Propulsion & Drivetrain segment, would transition to the Aftermarket segment. The Company also announced in 2022 that the canisters and fuel delivery modules business, previously reported in its Air Management segment, would transition to the Fuel Systems segment. Both of these transitions were completed during the second quarter of 2022. Additionally, in the fourth quarter of 2022, the Company moved its battery systems business, previously reported in its Air Management segment, to the former e-Propulsion & Drivetrain segment. The reportable segment disclosures have been updated accordingly, including recasting prior period information for the new reporting structures. Segment Adjusted Operating Income (Loss) is the measure of segment income or loss used by the Company. Segment Adjusted Operating Income (Loss) is comprised of operating income adjusted for restructuring, merger, acquisition and divestiture expense, intangible asset amortization expense, impairment charges and other items not reflective of ongoing operating income or loss. The Company believes Segment Adjusted Operating Income (Loss) is most reflective of the operational profitability or loss of our reportable segments.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting	The accompanying unaudited Condensed Consolidated Financial Statements of BorgWarner Inc. and Consolidated Subsidiaries (the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes necessary for a comprehensive presentation of financial position, results of operations and cash flow activity required by GAAP for complete financial statements. In the opinion of management, all normal recurring adjustments necessary for a fair statement of results have been included. Certain prior period amounts have been reclassified to conform to the current period presentation. Operating results for the three and six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. The balance sheet as of December 31, 2022 was derived from the audited financial statements as of that date. For further information, refer to the Consolidated Financial Statements and Footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.
Use of Estimates	Management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and accompanying notes, as well as the amounts of revenues and expenses reported during the periods covered by those financial statements and accompanying notes. Actual results could differ from these estimates.
New Accounting Pronouncements	In October 2021, the FASB issued ASU No. 2021-08, “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers.” It requires entities to apply ASC Topic 606, “Revenue from Contracts with Customers,” to recognize and measure contract assets and contract liabilities in a business combination. The amendments improve comparability after the business combination by providing consistent recognition and measurement guidance for revenue contracts with customers acquired in a business combination and revenue contracts with customers not acquired in a business combination. This guidance is effective for interim and annual reporting periods beginning after December 15, 2022. The Company adopted this guidance prospectively as of January 1, 2023, and there was no impact on the Condensed Consolidated Financial Statements.
