The automotive aftermarket is being reshaped by an expanding and ageing vehicle parc, changing component requirements and new purchasing channels.
S&P Global Mobility expects the global light-vehicle population in operation to reach 1.9 billion by 2034, up from 1.6 billion in 2025.
For parts manufacturers, distributors, workshops and OEMs, the opportunity is not simply the size of the aftermarket. It is identifying where vehicle ageing, utilization, technology and channel economics are creating the strongest pools of value.
An Older Parc Is Expanding Aftermarket Demand
Delayed new-vehicle purchases can amplify aftermarket demand as vehicles remain in service longer. According to ACEA, EU vehicle ages average 12.3 years for cars, 12.5 years for vans and 13.9 years for trucks.
Age alone does not determine replacement demand. Mileage, utilization, powertrain and operating conditions influence maintenance frequency. A high-mileage five-year-old commercial vehicle can therefore generate more aftermarket demand than an older privately used car.
Aftermarket planning needs to segment the vehicle parc by age, model, powertrain, usage and geography, rather than relying on registrations alone.
The Parts Mix Is Changing With Electrification
Electrification is changing aftermarket demand rather than eliminating it.
Traditional ICE-related categories such as engine components, exhaust systems and certain fluids face long-term pressure as EV penetration increases.
Meanwhile, demand remains relevant across tyres, braking systems, thermal management, electronics and EV-specific service equipment.
This creates different priorities across the value chain:
- Parts manufacturers need to assess exposure to declining ICE categories.
- Distributors need to adapt inventory to changing vehicle mixes.
- Workshops require new diagnostic and technical capabilities.
- OEMs need to reconsider long-term service and parts strategies.
The key question is which product categories will capture aftermarket spending as vehicle technology changes.
Vehicle Age Also Changes the Service Channel
The repair relationship evolves throughout the vehicle lifecycle.
Newer vehicles are more closely linked to OEM-authorized networks through warranties, scheduled maintenance and proprietary diagnostics. As vehicles age, independent workshops and aftermarket channels can become more competitive, particularly as customers become more price sensitive.
This creates a potential migration of value between OEM networks, independent repairers, distributors and parts retailers.
Workshop density alone is therefore insufficient. Repair frequency, vehicle concentration, labour economics, pricing and customer behaviour also determine service-market attractiveness.
Digital Channels Expand Reach but Pressure Margins
E-commerce is changing how aftermarket parts are discovered, compared and purchased. Digital platforms can improve availability and geographic reach, but greater price transparency can compress margins.
McKinsey found that 65% of surveyed aftermarket executives identified margin compression as a future risk, with e-commerce and increasing price transparency contributing to the pressure.
Digital aftermarket strategies therefore need to consider customer acquisition, fulfilment, pricing, fitment accuracy and channel conflict alongside sales growth.
Connectivity Creates Another Aftermarket Value Pool
Connected vehicles can extend aftermarket opportunities beyond traditional repair.
Vehicle data can support predictive maintenance, remote diagnostics, service reminders and targeted replacement recommendations. Fleet operators can use similar information to monitor vehicle health, utilization and maintenance requirements.
For OEMs, connectivity can strengthen service retention. For independent players, access to diagnostics and vehicle data can become increasingly important as vehicles become more electronic.
The commercial opportunity depends on converting data into services that improve uptime, maintenance economics or customer retention.
Where Aftermarket Value Is Most Attractive
The strongest opportunities typically combine:
- Large serviceable parc: Sufficient vehicles to create demand density.
- Age and utilization: Recurring maintenance and replacement requirements.
- Attractive category economics: Adequate margins and replacement frequency.
- Channel accessibility: Efficient access through workshops, distributors or digital platforms.
- Future resilience: Continued relevance as powertrains and technologies evolve.
These conditions vary by market. Mature markets can offer strong replacement demand through ageing fleets, while developing markets can combine growing vehicle populations with expanding service ecosystems.
Nexdigm’s Automotive Aftermarket Market Assessment
Nexdigm’s Market Assessment evaluates aftermarket opportunities through five dimensions:
- Vehicle Parc & Age Profile
Map vehicle populations by age, model, powertrain, utilization and geography. - Parts Demand Potential
Assess replacement cycles, component exposure and technology shifts. - Service Economics
Evaluate repair frequency, workshop density, pricing, labour costs and customer migration. - Channel Economics
Compare OEM, independent, distributor and e-commerce channels. - Future Market Resilience
Assess the impact of electrification, connectivity and changing vehicle technology.
The assessment can support portfolio strategy, market entry, distribution planning, workshop expansion and product prioritization.
Nexdigm’s Automotive Aftermarket Market Assessment
Nexdigm assessed aftermarket opportunities across 8 markets and 6 product categories, mapping vehicle age, parc growth, replacement cycles and channel economics. The analysis identified 3 priority product-service segments and highlighted the markets and channels offering the strongest expansion potential.
Automotive aftermarket value is increasingly shaped by which vehicles remain in operation, how intensively they are used and how customers access parts and services. An automotive aftermarket market assessment can help companies identify where these factors are converging to create the strongest commercial opportunities.
