Automotive Connecting Rod Market Overview

Global automotive connecting rod market size is estimated at USD 662.63 million in 2024, set to expand to USD 775.7 million by 2033, growing at a CAGR of 1.8%.

The automotive connecting rod market plays a crucial role in vehicle engine performance, linking the piston to the crankshaft to convert reciprocating motion into rotational motion. As of 2024, more than 90 million passenger and commercial vehicles were manufactured globally, all of which required connecting rods, with over 350 million units produced annually for OEM and aftermarket purposes. Increased demand for high-performance and fuel-efficient engines has led to a technological shift from cast iron to lightweight forged steel and aluminum alloys, particularly in Europe and Asia-Pacific. Forged connecting rods now account for over 55% of the total global demand due to superior fatigue resistance and strength. Hybrid and electric vehicle engines have also contributed to evolving product requirements, with over 17 million hybrid units in 2023 needing compact and lightweight connecting rod systems. With stringent emission regulations globally, particularly Euro 6 and BS-VI norms, demand for advanced engine components, including precision-engineered rods, is expanding. Additionally, the global aftermarket for automotive connecting rods continues to thrive due to rising vehicle parc, with over 1.4 billion vehicles on the road worldwide, resulting in substantial replacement cycles. These dynamics have intensified innovation and investment in this market segment, particularly in regions with growing automotive production capacities.

Key Findings

Top Country/Region: China holds the largest production and consumption share, contributing over 30% of global demand.

Top Segment: Forged connecting rods dominate the market, accounting for over 55% of usage across engine types.

Automotive Connecting Rod Market Trends

One of the dominant trends in the automotive connecting rod market is the increasing adoption of forged steel rods. In 2023, forged steel rods represented over 55% of the market due to their higher strength-to-weight ratio and longer fatigue life. These rods are essential for high-performance and turbocharged engines, which have witnessed over 20 million units deployed globally in passenger cars and sports vehicles.

Another emerging trend is the shift towards lightweight materials such as aluminum and titanium in performance vehicles. Over 12 million vehicles utilized aluminum connecting rods in 2023, largely in the sports and premium automotive segments. Manufacturers are adopting these to enhance engine efficiency by reducing reciprocating weight.

The automotive aftermarket is also witnessing significant transformation. With the global vehicle parc crossing 1.4 billion units in 2023, replacement cycles for connecting rods have shortened, especially in heavy commercial vehicles, where average maintenance intervals are 80,000–120,000 km. Asia-Pacific has seen a rapid surge in aftermarket sales, accounting for over 40% of global aftermarket connecting rod sales.

Automotive Connecting Rod Market Dynamics

DRIVER

Rising demand for fuel-efficient and high-performance engines.

As global emission regulations become stricter, automakers are under pressure to reduce engine weight while maintaining durability and output. This has increased the use of lightweight forged steel and powder metal connecting rods in engine assemblies. For instance, the global production of turbocharged engines, which require robust connecting rods, exceeded 20 million units in 2023. Automakers are increasingly shifting to forged rods, which weigh approximately 20% less than conventional cast iron versions and offer up to 75% higher fatigue resistance. In hybrid vehicle applications, where space and thermal tolerance are critical, the connecting rod design must accommodate high-speed combustion cycles and elevated temperatures, making high-strength materials essential.

RESTRAINT

Volatility in raw material prices.

Connecting rod manufacturing depends on materials like high-grade steel, aluminum, and titanium. Price fluctuations in these raw materials affect manufacturing costs. For example, steel prices increased by over 30% between 2021 and 2023, while aluminum surged by nearly 25% in the same period. This makes it challenging for smaller manufacturers to maintain price competitiveness. Moreover, the cost of powder metallurgy inputs has also seen inflation due to energy supply chain disruptions, thereby restraining market growth, especially in cost-sensitive regions like Africa and Latin America. OEMs may reduce procurement volume or extend sourcing to low-cost regions, disrupting supply chains.

OPPORTUNITY

Technological innovations in lightweight and high-strength alloys.

The development of sintered metal rods and composite connecting rods offers new market opportunities. In 2023, over 5 million connecting rods were produced using powder metallurgy, particularly for small displacement and two-wheeler engines. These rods deliver excellent wear resistance and maintain tolerances under high load conditions. Advanced forging techniques and materials such as micro-alloyed steel and titanium allow manufacturers to produce ultra-light rods with up to 15% weight savings. These innovations are especially in demand in electric vehicle range extenders and plug-in hybrids, expected to represent over 8 million unit installations by 2026.

CHALLENGE

Engine downsizing and electrification.

The global shift toward electric mobility poses a significant challenge to the automotive connecting rod market. BEVs (Battery Electric Vehicles), which do not use internal combustion engines, do not require connecting rods. In 2023 alone, over 11 million BEVs were sold, directly eliminating the need for rods in those units. This gradual transition, particularly in Europe and North America, may shrink the addressable market. Meanwhile, smaller engine sizes in hybrid vehicles require highly customized rod designs, increasing engineering and production complexity, which not all manufacturers can handle efficiently.

Automotive Connecting Rod Market Segmentation

The automotive connecting rod market is segmented by type into forged, cast, and powder metal rods, and by application into passenger cars and commercial vehicles. Each segment presents distinct material, performance, and production characteristics.

By Type

• Forged Connecting Rods: Forged rods dominate the market with over 55% global share in 2023. These rods are manufactured using hot forging processes that enhance mechanical properties like tensile strength and fatigue resistance. Widely used in performance and commercial engines, forged rods offer 25% higher fatigue limits than cast versions and are typically made from 4340 or EN24 steel. Over 100 million forged connecting rods were produced globally in 2023, particularly in Asia and Europe.
• Cast Connecting Rods: Cast iron rods accounted for around 30% of market share in 2023. These are primarily used in cost-sensitive, low-performance applications due to their ease of production and affordability. However, cast rods have lower strength-to-weight ratios and are more prone to fatigue cracks. India and Brazil remain strong markets for cast rods, especially in low-displacement and utility vehicle engines. Nearly 60 million units were produced in 2023.
• Powder Metal Connecting Rods: Powder metal rods comprised about 15% of global production in 2023. Their uniform microstructure and precision manufacturing allow tight tolerances and lightweight profiles. Used mainly in motorcycles and compact engines, these rods are projected to grow with increasing two-wheeler demand in Southeast Asia. Over 20 million powder metal rods were manufactured globally in 2023, especially in Japan, Taiwan, and Indonesia.

By Application

• Passenger Cars: Passenger cars accounted for over 65% of connecting rod demand in 2023, with more than 160 million rods used globally. Downsizing trends and turbocharging technologies have driven adoption of forged and powder metal rods in cars, especially in compact and mid-sized models. In Europe, over 90% of new passenger cars use turbocharged engines, necessitating precision-engineered connecting rods.
• Commercial Vehicles: Commercial vehicles held a 35% market share, representing over 85 million units in 2023. High-duty cycles and torque requirements mean these engines demand forged rods with high tensile strength (up to 1200 MPa) and durability. Trucks, buses, and off-road vehicles in the U.S. and China dominate this segment, with aftermarket replacements forming a large portion of demand.
