The global automotive connecting rod market is poised for steady growth, expected to expand from USD 14.7 billion in 2025 to USD 22.5 billion by 2035, registering a CAGR of 4.4% during the forecast period. This growth is driven by continued reliance on internal combustion engine (ICE) technologies, the rise of hybrid vehicles, and the increasing use of advanced lightweight materials to enhance fuel efficiency and performance in both passenger and motorsport vehicles.
In 2024, CP-Carrillo introduced a new line of titanium and aluminum alloy connecting rods at the PRI Show, designed to reduce reciprocating mass and enhance strength-to-weight ratios for high-performance and racing applications. As reported by EngineLabs, titanium rods offer superior fatigue resistance, while aluminum variants are ideal for short-distance racing due to lower inertia. These innovations are now being used in drag and endurance racing, where thermal and dynamic stress management is crucial.
