Why and how automotive suppliers must now diversify consistently
The structural transformation of the automotive industry is forcing automotive suppliers to fundamentally rethink their business models. Electrification, softwareization, and geopolitical uncertainties are putting pressure on traditional volume and margin models. Strategic diversification by automotive suppliers is therefore not a diversionary tactic, but a key prerequisite for long-term competitiveness and resilient growth.
Attractive areas of diversification for automotive suppliers
Energy and Charging Infrastructure
Automotive suppliers with in-depth expertise in power electronics, thermal management, and series production should invest specifically in energy and charging infrastructure. These skills can be transferred almost directly to charging hardware, energy storage solutions, and grid integration. The underlying markets promise long-term growth – regardless of the volatility of the automotive sector – and also benefit from global investments in the energy transition.
Medical Technology
Medical technology also offers attractive diversification opportunities for high-precision suppliers. Skills in mechatronics, sensor technology, and strict quality management (zero-defect approaches) are critical to success in this field. Although regulatory barriers to entry are high, these are more than offset by more stable margins, more predictable volumes, and lower economic dependence.
Industrial Automation and Robotics
Industrial automation and robotics are natural follow-up markets. Suppliers are familiar with highly automated production environments from their own experience and can further develop existing expertise in actuators, control systems, gearboxes, and sensor technology. Fields of application range from industrial and logistics automation to collaborative robotics and military and safety-critical systems.
Aviation, Aerospace, and Drone Technology
For specialized providers, it is also worth entering the aviation, aerospace, and drone technology sectors. Expertise in lightweight construction, high reliability, and safety-critical systems is particularly in demand here. Unmanned systems such as drones and urban air mobility in particular offer lower barriers to entry and shorter innovation cycles compared to traditional aviation.
Hydrogen and Fuel Cell Technologies
Hydrogen and fuel cell technologies are opening up further industrial markets, particularly for components such as valves, seals, and control systems. Even though the passenger car sector remains uncertain, demand for hydrogen solutions in industrial applications, heavy-duty transport, and energy supply is growing steadily.
Rail, Commercial Vehicle, and Off-Highway Markets
Diversification into the rail, commercial vehicle, agricultural, and construction machinery markets also reduces dependence on the passenger car business. Many technical requirements are similar to those in the automotive industry, so economies of scale remain possible. At the same time, these markets are characterized by longer product cycles, different innovation logic, and often more stable demand.
Rethinking the business model
Software- and Data-Based Business Models
At the same time, software- and data-based business models must become an integral part of any diversification strategy. The future of mobility and many industries is software-driven. Suppliers who combine hardware with software, data analysis, or AI can evolve from pure component suppliers to solution providers. This results in recurring revenues, higher margins, and stronger customer loyalty.
Aftermarket & Services
Regardless of the target market, the aftermarket and service business should be systematically expanded. Spare parts, retrofit solutions, predictive maintenance, and digital services offer higher margins and significantly stronger customer loyalty than pure new business—and this is largely independent of the respective drive concept.
Sustainability & Circular Economy
Furthermore, sustainability and the circular economy can become independent business models. Suppliers are able to monetize their process and production knowledge—even outside the automotive industry. Recycling, remanufacturing, CO₂-optimized materials, and sustainable manufacturing processes are increasingly in demand and promoted by regulations.
Organization as a Success Factor: Why Diversification Often Fails Internally
However, organizational implementation is crucial to the success of any diversification. New business areas often fail due to existing mindsets, structures, and KPIs of the core business. A clear organizational separation with separate units, a distinct culture, adapted management logic, and genuine freedom of decision-making significantly increases the chances of success—especially in new, dynamic markets.
Conclusion: Diversification as a further development of the supplier model
Diversification is not an experiment, but rather a strategic advancement of the supplier model. Companies that consistently transfer existing expertise, integrate software and services, and take new business areas seriously from an organizational perspective can achieve lasting independence from the cyclical passenger car market.
