阻礙市場成長的主要障礙之一是全球向電池式電動車的快速轉型,這種轉型徹底淘汰了內燃機。儘管發生了這一根本性變化,傳統汽車的產量仍然龐大,有效地維持了對這些零件的需求。根據中國汽車工業協會的數據,到2024年,中國累計汽車產量將達到3,128萬輛。如此強勁的生產表現表明,傳統汽車和混合動力汽車的組裝將繼續帶動連桿的大量訂單。
全球汽車產量和銷售量的成長是連桿製造的主要驅動力。隨著整車製造商(OEM)提高產量以滿足消費者需求,內燃機的需求依然強勁,直接帶動了零件訂單。儘管電氣化發展迅速,但新興市場汽油和柴油引擎的大規模生產確保了動力傳動系統零件的持續需求。例如,根據印度汽車製造商協會(SIAM)2024年4月發布的“快報”,預計2023-2024會計年度印度國內乘用車銷量將達到創紀錄的421萬輛。汽車組裝量的成長帶動了多缸引擎連桿供應需求的增加,維持了生產線的運轉,並為鍛鐵和鑄鐵產品創造了穩定的需求。
此外,重型商用車領域的成長將成為高抗張強度鋼連桿市場的主要驅動力。這些車輛在建築和物流領域廣泛使用高扭矩柴油引擎,因此需要能夠承受巨大氣缸壓力的堅固動力傳動系統系統。根據歐洲汽車製造商協會 (ACEA) 於 2024 年 11 月發布的《商用車註冊報告》,歐盟新廂型車銷量在前三個季度成長了 8.5%,達到 117 萬輛。與乘用車相比,該細分市場受快速電氣化的影響較小,這為供應商提供了長期穩定性。為了支持供應鏈滿足這些需求,印度汽車零件製造商協會宣布,預計 2024 年印度汽車零件產業的銷售額將達到 741 億美元。
全球加速向純電動車(BEV)轉型,對連桿市場的成長構成了重大的結構性障礙。這項挑戰源自於動力傳動系統設計的固有差異:純電動車由電動馬達而非內燃機驅動,因此無需曲軸、活塞以及連接它們的連桿。隨著整車製造商逐步將資本投資和組裝流程轉向電動平台,對傳統引擎零件的相對需求自然下降,從而有效地縮小了連桿製造商的潛在市場。
近期主要汽車市場的生產趨勢清楚地顯示了這種需求轉移。根據中國汽車工業協會(CAAM)報告顯示,到2024年,新能源汽車產量將達到1,289萬輛。這一龐大的數字意味著,屆時將有約1300萬輛汽車進入市場,而這些汽車並不需要任何連桿。隨著新能源汽車市場佔有率的擴大,內燃機零件訂單的下降直接抑制了連桿產業的生產成長,抵消了全球汽車保有量擴張帶來的潛在收益。
隨著汽車製造商加速採用混合動力技術,從內燃機汽車向純電動車轉型,專為混合動力傳動系統開發的連桿正在改變設計標準。與傳統內燃機不同,混合動力系統由於頻繁的啟動停止操作以及瞬時高扭力輸出的需求,使連桿承受獨特的應力循環。這就要求零件兼具低往復運動質量和極高的疲勞強度。電動車對先進內燃技術的持續依賴,確保了對高規格動力傳動系統零件的需求不斷成長。根據金屬粉末工業聯合會 (MPIF) 2025 年 6 月發布的《北美粉末冶金行業現狀 - 2025》報告,2024 年傳統混合動力汽車的銷量將成長約 37%,這表明與內燃機兼容的零件在現代車隊中的重要性日益凸顯。
同時,採用中空連桿設計來減輕重量正成為一大趨勢,這使得引擎能夠提高熱效率並實現更高的轉速。汽車製造商擴大使用這些輕量化、結構複雜的零件,以滿足全球日益嚴格的燃油經濟性法規,同時保持小型化渦輪增壓引擎所需的結構耐久性。這種向精密工程、高價值動力傳動系統總成組件的轉變,為能夠生產此類先進設計的零件製造商帶來了顯著的收益。例如,根據Linamar公司於2025年3月發布的2024年度報告,由於每輛車零件使用量的增加以及採用這些先進技術的新動力系統專案的成功部署,該公司移動出行部門的正常化營業利潤同比成長了30.6%。
The Global Automotive Engine Connecting Rods Market is projected to expand from USD 43.12 Billion in 2025 to USD 57.00 Billion by 2031, reflecting a compound annual growth rate of 4.76%. As a critical powertrain element, the connecting rod transforms the reciprocating motion of the piston into the rotary motion of the crankshaft to propel the vehicle. Market progression is chiefly underpinned by sustained requirements for internal combustion engine vehicles in developing nations and the continued dependence on commercial vehicles for logistics, which demand the high torque characteristics of conventional engines. Furthermore, the aging global vehicle fleet generates a consistent revenue stream for the aftermarket sector through necessary engine overhauls and component replacements.

One major obstacle retarding market growth is the swift global shift toward battery electric vehicles, which entirely remove the internal combustion engine. Despite this fundamental change, the volume of traditional automobile manufacturing remains significant, effectively maintaining demand for these components. Data from the China Association of Automobile Manufacturers indicates that cumulative automobile production in China hit 31.28 million units in 2024. This strong manufacturing output demonstrates that the assembly of conventional and hybrid vehicles continues to drive substantial orders for connecting rods.
Market Driver
The escalation in global vehicle production and sales volumes acts as the primary propellant for connecting rod manufacturing. As original equipment manufacturers increase output to satisfy consumer demand, the need for internal combustion engines remains high, resulting in direct component orders. Although electrification is growing, the vast scale of gasoline and diesel engine production in emerging markets guarantees a persistent requirement for powertrain parts. For instance, the Society of Indian Automobile Manufacturers reported in their April 2024 'Flash Report' that domestic passenger vehicle sales achieved a record 4.21 million units in the 2023-24 fiscal year. This uptick in vehicle assembly mandates a corresponding supply of connecting rods for multi-cylinder engines, thereby upholding production lines and generating steady demand for forged and cast iron products.
Furthermore, the growth of the heavy-duty and commercial vehicle sectors acts as a vital catalyst for the market, especially regarding high-strength steel connecting rods. These vehicles, which rely heavily on high-torque diesel engines for construction and logistics, demand robust powertrain systems capable of enduring immense cylinder pressure. According to the European Automobile Manufacturers' Association's 'Commercial Vehicle Registrations' report from November 2024, new van sales in the EU rose by 8.5 percent to 1.17 million units in the first three quarters. Because this segment is less prone to rapid electrification than passenger cars, it offers long-term stability for suppliers. Underscoring the strength of the supply chain catering to these needs, the Automotive Component Manufacturers Association of India noted that the automotive component industry's turnover reached USD 74.1 billion in 2024.
Market Challenge
The accelerated global move toward battery electric vehicles presents a major structural barrier to the connecting rod market's growth. This difficulty stems from the inherent difference in powertrain design; battery electric vehicles rely on electric motors for propulsion rather than internal combustion engines, meaning they do not require crankshafts, pistons, or the connecting rods that join them. As automotive original equipment manufacturers progressively redirect their capital investments and assembly operations toward electric platforms, the relative demand for conventional engine parts is naturally depressed, effectively contracting the addressable market for manufacturers of connecting rods.
Recent production trends in major automotive markets clearly illustrate this displacement of demand. As reported by the China Association of Automobile Manufacturers, the production of new energy vehicles hit 12.89 million units in 2024. This significant figure represents nearly thirteen million vehicles entering the market without requiring a single connecting rod. As the market share of these vehicles grows, the associated decline in orders for internal combustion engine components directly inhibits volume growth in the connecting rod sector, neutralizing gains that would otherwise arise from the general expansion of the global vehicle fleet.
Market Trends
The creation of specialized connecting rods for hybrid powertrains is altering engineering standards as automakers increasingly adopt hybridization to transition from internal combustion to full electrification. Unlike conventional combustion engines, hybrid systems subject connecting rods to unique stress cycles caused by frequent start-stop sequences and the necessity for instant high-torque delivery, requiring components that balance low reciprocating mass with extreme fatigue strength. This continued dependence on advanced internal combustion technology within electrified models guarantees ongoing volume growth for high-specification powertrain parts. According to the Metal Powder Industries Federation's June 2025 'State of the PM Industry in North America-2025' report, sales of traditional hybrid vehicles rose by approximately 37 percent in 2024, emphasizing the growing importance of combustion-engine mating components in modern fleets.
Simultaneously, the adoption of hollow connecting rod designs to reduce weight is emerging as a key trend, allowing engines to attain improved thermal efficiency and higher rotational speeds. Automakers are increasingly specifying these lightweight, complex components to satisfy rigorous global fuel economy regulations while maintaining the structural durability needed for turbocharged, downsized engines. This move toward precision-engineered, high-value powertrain assemblies is yielding significant returns for component manufacturers equipped to produce such advanced designs. For instance, Linamar Corporation's March 2025 'Annual Report 2024' indicated that normalized operating earnings for its Mobility segment rose by 30.6 percent over the prior year, fueled by increased content per vehicle and the successful rollout of new propulsion programs employing these sophisticated technologies.
