Drivers
Modern cars have sophisticated parts, intricate electronic systems, and cutting-edge technologies. Many customers and even some vehicle repair companies may require additional knowledge and abilities to maintain and repair this complexity. Therefore, the need for aftermarket services to handle these complications is rising. Modern automobiles last longer because of advancements in engineering and manufacturing despite their increasing complexity. The need for aftermarket services is further increased because automobiles require regular maintenance and repairs as they age. Thereby, the rising complexity of modern vehicles is observed to act as a driver for the
These preferences consider several variables, such as evolving lifestyles, economic concerns, environmental concerns, and technological improvements. Customers are looking for more customized and environmentally friendly transportation options, so aftermarket goods and services are in high demand. For example, the growing demand for EV charging stations and associated accessories results from the increasing popularity of electric vehicles (EVs). Similarly, the demand for personalization and customization has driven the market for aftermarket components like linked automobile technologies, performance increases, and cosmetic modifications.
Furthermore, as automobiles grow increasingly intricate and advanced, buyers want aftermarket systems that provide connection, safety, and convenience features. The development of aftermarket items like sophisticated navigation systems, collision avoidance systems, and smartphone integration has been fueled by this trend.
Restraint
Rise of electric vehicles (EVs)
In contrast to conventional internal combustion engine vehicles, electric vehicles have fewer moving parts. This means that parts like spark plugs, belts, and filters frequently changed in conventional cars are either absent in EVs or require less regular maintenance. This decline in part demand directly impacts the merchants and aftermarket suppliers who depend on selling these components. The aftermarket for parts intended for conventional vehicles is well-established, but the one for electric car parts is still growing. Because of this, it can be difficult for aftermarket companies to find and carry parts designed specifically for electric vehicles while competing with OEMs that can control most of the supply chain.
Opportunities
Aftermarket electric car parts (EVs) will become increasingly in demand as more EVs are driven on public roads. This covers EV-specific accessories, batteries, electric drivetrain parts, and charging stations. The number of EVs on the road will increase demand for infrastructure related to charging. The aftermarket sector may utilize this by offering cutting-edge charging options for homes, businesses, and public areas.
For aftermarket businesses, subscription models offer a reliable source of income, facilitating more stable and effective financial planning. Aftermarket companies can boost client relationships and increase lifetime value and loyalty by providing subscription-based services like maintenance, repairs, and part replacements. By renovating and remanufacturing used parts rather than creating brand-new ones, adopting circular economy concepts can assist aftermarket businesses in cutting waste and lessening their environmental effect. Remanufacturing and refurbishing items can result in cost savings for organizations and consumers as they are often less expensive than manufacturing new ones.
The hard parts segment held a dominant presence in the market in 2024, owing to the rising age and mileage of vehicles, and the increasing expansion of e-commerce platforms for parts distribution.
