Within the electric vehicle aftermarket market, Transmission and Steering held a 24.52% share in 2025, making it the leading replacement parts segment. This position is sustained by the essential nature of steering assemblies, drivetrain-linked components, and related mechanical systems that directly affect vehicle control, handling, and roadworthiness. In the electric vehicle aftermarket market, these parts tend to generate consistent replacement demand because wear, alignment stress, and operational reliability cannot be deferred for long, especially once vehicles enter broader day-to-day usage.

Lighting is emerging as the fastest-growing segment in the electric vehicle aftermarket market as owners and service networks respond to rising demand for replacement and upgrade cycles tied to visibility, safety, and evolving vehicle design standards. Growth is gaining pace relative to other replacement parts because lighting components are more exposed to frequent replacement needs from minor damage, technology refresh preferences, and compatibility requirements across newer EV models. As the installed base expands, the practical ease of replacing lighting systems compared with more complex mechanical components is helping this segment build momentum.

Use Segment Analysis: Business to Customer (Largest Segment) vs Business to Business (Fastest-Growing Segment)

By 2025, Business to Customer accounted for the largest share in the electric vehicle aftermarket market, reflecting the direct role of individual EV owners in purchasing replacement products and maintenance-related components. The segment’s leadership is underpinned by routine aftermarket spending patterns where consumers independently seek parts for upkeep, repair, and model-specific replacements through retail and service channels. In the electric vehicle aftermarket market, this direct end-user demand keeps Business to Customer firmly ahead because replacement decisions are often triggered by immediate ownership needs rather than longer procurement cycles.

Business to Business is the fastest-growing use segment in the electric vehicle aftermarket market as fleet operators, workshops, service aggregators, and commercial maintenance networks increase procurement volumes for EV-specific parts. Its momentum is strengthening relative to Business to Customer because institutional buyers are scaling more structured servicing operations as electric vehicle fleets expand and require predictable maintenance support. The need for repeat purchasing, standardized parts sourcing, and service efficiency is creating a stronger growth path for Business to Business in the electric vehicle aftermarket market.
