阻碍市场成长的主要障碍之一是全球向电池式电动车的快速转型,这种转型彻底淘汰了内燃机。儘管发生了这一根本性变化,传统汽车的产量仍然庞大,有效地维持了对这些零件的需求。根据中国汽车工业协会的数据,到2024年,中国累计汽车产量将达到3,128万辆。如此强劲的生产表现表明,传统汽车和混合动力汽车的组装将继续带动连桿的大量订单。
全球汽车产量和销售量的成长是连桿製造的主要驱动力。随着整车製造商(OEM)提高产量以满足消费者需求,内燃机的需求依然强劲,直接带动了零件订单。儘管电气化发展迅速,但新兴市场汽油和柴油引擎的大规模生产确保了动力传动系统零件的持续需求。例如,根据印度汽车製造商协会(SIAM)2024年4月发布的“快报”,预计2023-2024财年印度国内乘用车销量将达到创纪录的421万辆。汽车组装量的成长带动了多缸引擎连桿供应需求的增加,维持了生产线的运转,并为锻铁和铸铁产品创造了稳定的需求。
此外,重型商用车领域的成长将成为高抗拉强度钢连桿市场的主要驱动力。这些车辆在建筑和物流领域广泛使用高扭矩柴油发动机,因此需要能够承受巨大气缸压力的坚固动力传动系统系统。根据欧洲汽车製造商协会 (ACEA) 于 2024 年 11 月发布的《商用车註册报告》,欧盟新厢型车销量在前三个季度增长了 8.5%,达到 117 万辆。与乘用车相比,该细分市场受快速电气化的影响较小,这为供应商提供了长期稳定性。为了支持供应链满足这些需求,印度汽车零件製造商协会宣布,预计 2024 年印度汽车零件产业的销售额将达到 741 亿美元。
全球加速向纯电动车(BEV)转型,对连桿市场的成长构成了重大的结构性障碍。这项挑战源自于动力传动系统设计的固有差异:纯电动车由电动马达而非内燃机驱动,因此无需曲轴、活塞以及连接它们的连桿。随着整车製造商逐步将资本投资和组装流程转向电动平台,对传统引擎零件的相对需求自然下降,从而有效地缩小了连桿製造商的潜在市场。
近期主要汽车市场的生产趋势清楚地显示了这种需求转移。根据中国汽车工业协会(CAAM)报告显示,到2024年,新能源汽车产量将达到1,289万辆。这一庞大的数字意味着,届时将有约1300万辆汽车进入市场,而这些汽车并不需要任何连桿。随着新能源汽车市场份额的扩大,内燃机零件订单的下降直接抑制了连桿产业的生产成长,抵消了全球汽车保有量扩张带来的潜在收益。
随着汽车製造商加速采用混合动力技术,从内燃机汽车向纯电动车转型,专为混合动力传动系统开发的连桿正在改变设计标准。与传统内燃机不同,混合动力系统由于频繁的启动停止操作以及瞬时高扭力输出的需求,使连桿承受独特的应力循环。这就要求零件兼具低往復运动质量和极高的疲劳强度。电动车对先进内燃技术的持续依赖,确保了对高规格动力传动系统零件的需求不断增长。根据金属粉末工业联合会 (MPIF) 2025 年 6 月发布的《北美粉末冶金行业现状 - 2025》报告,2024 年传统混合动力汽车的销量将增长约 37%,这表明与内燃机兼容的零件在现代车队中的重要性日益凸显。
同时,采用中空连桿设计来减轻重量正成为一大趋势,这使得引擎能够提高热效率并实现更高的转速。汽车製造商越来越多地使用这些轻量化、结构复杂的零件,以满足全球日益严格的燃油经济性法规,同时保持小型化涡轮增压引擎所需的结构耐久性。这种向精密工程、高价值动力传动系统总成组件的转变,为能够生产此类先进设计的零件製造商带来了显着的收益。例如,根据Linamar公司于2025年3月发布的2024年度报告,由于每辆车零件使用量的增加以及采用这些先进技术的新动力系统专案的成功部署,该公司移动出行部门的正常化营业利润同比增长了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.
