Automotive Crankshaft Market Size Worth USD 7.59 Billion by 2034 | CAGR: 4.1%

The global automotive crankshaft market size is expected to reach USD 7.59 billion by 2034, according to a new study by Polaris Market Research. The report “Automotive Crankshaft Market Size, Share, Trends, Industry Analysis Report By Crankshaft Type (Forged Crankshaft, Cast Crankshaft, Billet Crankshaft), By Material, By Manufacturing Process, By Vehicle Type, By Region – Market Forecast, 2025–2034” gives a detailed insight into current market dynamics and provides analysis on future market growth.

An automotive crankshaft is a core mechanical component found within the internal combustion engine of vehicles. Its fundamental role is to convert the linear, up-and-down motion of the pistons into rotational movement, which is then used to power the vehicle's wheels through the drivetrain. This intricate component is crucial for engine performance, overall vehicle operation, and ensuring the smooth and efficient transfer of power. Typically crafted from materials such as cast iron or forged steel, crankshafts are engineered to withstand immense stresses, maintain precise balance at high speeds, and offer long-term durability, making them indispensable to the functioning of any vehicle powered by an internal combustion engine.

The automotive crankshaft market is a vital segment of the broader automotive industry, driven primarily by the global production and sales of new vehicles, encompassing both passenger cars and commercial vehicles. Key factors influencing this market include ongoing advancements in engine technology, such as downsizing and turbocharging, which necessitate more robust and precisely engineered crankshafts capable of handling increased power density. Furthermore, the global push for stricter fuel efficiency and emissions regulations continuously propels innovation in crankshaft design and materials, favoring lighter and more durable components. While the long-term outlook is shaped by the rise of electric vehicles, the current and near-future demand remains strong due to the widespread reliance on internal combustion engines and hybrid powertrains, alongside a significant aftermarket for replacement parts.
