EV-specific components are anticipated to be the fastest growing component segment of the automotive parts and components market expanding at 17.33% CAGR during 2026-2031. The EV-specific components market growth is supported by accelerating adoption of EVs and increasing regional policies, incentives, and subsidies to promoting electric powertrain technologies. EVs account for approximately one-quarter of global new-car sales in 2025. The EV-specific components segment comprises battery pack, BMS, DC-DC converter, inverter, E-axle, charging module, thermal-management systems, and others. Among these, Batteries represent the largest value and high contribution in EV-specific components . Overall, positioned as a principal growth area as global EV sales and production scale up.

OEM sales channel accounts 62.36% og global automotive parts and components market share in 2025, while aftermarket is anticipated to grow at 15.54% during 2026-2031. OEM channels are driven by vehicle production and increasing the value and complexity of components integrated in vehicles. Adoption of EVs, ADAS, connectivity, advanced electronics, and lightweight materials is increasing demand for high-value components. OEMs are strengthening supplier partnerships and supply-chain diversification to improve resilience and manage geopolitical and logistics risks.

Aftermarket remained a resilient demand segment in 2025, supported by the expanding global vehicle parc, increasing average vehicle age, regular maintenance and decreasing vehicle affordability. Demand is shifting towards higher-value electronic components, sensors, braking systems, batteries, and thermal-management parts, while E-commerce, digital catalogues, online ordering, and predictive diagnostics are transforming aftermarket distribution and improving parts availability. Aftermarket provides a stable, technology-driven revenue supported by vehicle ageing, maintenance requirements, and digitalization.

Asia Pacific registered the highest global automotive parts and components market share of 62.50% in 2025. Asia Pacific's dominance in the global automotive parts and components market is primarily supported by China, Japan, India, and South Korea. China's well-established automotive manufacturing and EV ecosystem, supported by an integrated battery supply chain and rising vehicle exports are collectively driving demand for automotive parts and components.

China manufactured nearly 34.53 million vehicles in 2025, making it the largest automotive production hub, while extensive OEM and Tier-1/Tier-2 supplier network supports demand for powertrain, body, chassis, electrical and electronic components. India manufactured approximately 6.49 million vehicles in 2025 by expanding production capacity, growing aftermarket demand, increasing domestic demand, localization initiatives, and rising component exports. With increasing localization, governments and OEMs supporting the domestic manufacturing of critical components, EV batteries, semiconductors and electric motors. This is encouraging Tier-1 suppliers to establish or expand regional production facilities. While Japan and South Korea remain strong in advanced electronics, hybrid powertrains, semiconductors, and precision components are the key attributes allowing Asia Pacific to be at the top of global automotive parts and components.

Middle East & Africa is projected to be the fastest region in global automotive parts and components by 2031, accounting for 15.06% CAGR. Continued expansion of the global automotive parts and components market is poised to be driven by vehicle-parc expansion, increasing electric vehicle adoption, ageing fleets, automotive localization, digital parts distribution, and increasing commercial-vehicle activity. GCC countries, South Africa, and Egypt remain key regional markets, while expanding manufacturing investments create opportunities for local and international component suppliers. Increasing vehicle utilization, and rising investment in automotive manufacturing.
