What are the top economic and technological drivers pushing car parts market growth?
The rise in aging vehicles is expected to propel the growth of the car parts market going forward. Aging vehicles refer to cars that have been in use for over 8–10 years and continue to operate, often requiring frequent maintenance, repairs, and replacement parts to remain roadworthy. The rise in aging vehicles is driven by improved vehicle durability, allowing cars to remain reliable and in use for longer periods. Car parts play a crucial role in supporting aging vehicles by enabling timely repairs and replacements that extend their lifespan and maintain performance. For instance, in April 2025, according to a report published by CCC Intelligent Solutions Inc., a US-based SaaS platform provider for the property and casualty (P&C) insurance economy, in 2024, the average age of U.S. vehicles on the road rose to 12.7 years and is expected to reach 13 years by 2026. Therefore, the rising number of aging vehicles is driving growth in the car parts market.

Which major trends are influencing the growth of the car parts industry?
Major companies operating in the car parts market are focusing on developing innovative solutions, such as brake-by-wire (BbW) systems, to enhance vehicle safety, responsiveness, and integration with advanced driver-assistance and autonomous driving technologies. Brake-by-wire (BbW) systems refer to advanced braking technologies that replace traditional mechanical and hydraulic linkages with electronic controls to activate the vehicle’s brakes. For instance, in April 2025, Nexteer Automotive, a US-based automotive manufacturer, introduced the Electro-Mechanical Brake (EMB) system, a state-of-the-art brake-by-wire (BbW) solution that improves chassis control, efficiency, and vehicle safety. This innovation enables precise, independent control of each wheel, enhancing vehicle stability, reducing response times, and improving overall safety and comfort, particularly beneficial for electric vehicles where noise and vibration reduction are critical. By eliminating hydraulic components, the EMB system contributes to vehicle lightweighting, optimizes energy efficiency, and reduces maintenance needs, aligning with the industry's shift towards more sustainable and software-defined vehicle architectures.
