    United States Car Parts Aftermarket Market Trends

    Increasing Online Sales of Aftermarket Car Parts and Components drives market growth.

    The United States aftermarket car parts and components market is anticipated to grow positively due to a rise in people's internet activity. Producers can now supply high-quality items faster because of technological advancements and the accelerating pace of logistical progress, which has propelled market expansion. E-commerce activity is growing faster than expected due to the ongoing epidemic. In Addition, in 2020, the automobile aftermarket proved its tenacity once more with better-than-expected performance despite the global COVID-19 pandemic. In 2021, there was a notable industry recovery.

    In 2021, the total aftermarket sales of light-duty vehicles in the United States will increase by approximately 11.2%, reaching USD 325 billion.

    Historically, online parts sales growth rate has been roughly 16% per year; however, in 2021, e-commerce operations had a 30% spike due to the coronavirus pandemic. Accessories, aftermarket, and replacement parts fall under this category. Therefore, throughout the forecast period, this pandemic has given the leading players in the market profitable chances. Furthermore, the expansion of the automobile sector is impacted by the yearly increase in the market for electric vehicles.

    In 2021, the United States yearly sales of plug-in electric vehicles exceeded 172.1 thousand units, demonstrating the significant demand for parts and components to meet the demands of this industry. Furthermore, the United States is the biggest producer of plug-in hybrid automobiles. The nation is also the market leader for these automobiles, with top producers including Cadillac, GMC, Tesla, and Chrysler.

    Moreover, plug-in electric car sales have risen in the United States over the past few years due to the industry's ongoing shift towards e-mobility. Electric vehicles are significantly less complex than traditional powertrain automobiles, with about 2,000 components. According to Tesla, for example, the drivetrain of its model has just 17 moving parts total, of which two are found in the motor. It is expected that automotive component makers will begin manufacturing their related parts because the drivetrain is the engine of any electric car.

    In Addition, it is estimated that approximately 150,000 of the 590,000 American workers employed in the car parts industry make internal combustion engine (ICE) components.
