Is now a good time to purchase an electric vehicle given potential future supply chain disruptions?
A July 2026 study by EY assessed vulnerabilities across 10 key automotive components for electric vehicles. The findings highlight how global competition for critical materials may impact future vehicle availability for consumers.
Why it matters
The concentration of production centers means that electric vehicle manufacturers must compete with AI infrastructure, data centers, and defense sectors for essential parts. This structural dependency creates potential for delayed deliveries and increased pricing pressures for car buyers.
The EY research assessed 10 critical automotive materials and components, including semiconductors, silicon, and copper. These items are currently subject to high demand from competing industries, limiting manufacturers' capacity to respond to sudden supply disruptions.
The players
EY
A global professional services firm that produces data-driven analysis on industrial market trends.
ACEA
The European Automobile Manufacturers Association, which monitors industrial policy and the automotive manufacturing landscape.
The details
Supply chains for many major automotive brands are vulnerable because they rely on the same limited processing centers and suppliers globally. Because qualifying new suppliers and extending production capacity takes significant time, manufacturers struggle to pivot when these shared components are diverted to other high-growth sectors like renewable energy or data centers.

The Home Front
The automotive industry is shifting from a focus on internal production efficiency to managing intense external competition for raw materials. This trend suggests a long-term recalibration of how vehicle supply chains are managed to ensure domestic availability.
If you are planning to purchase a new electric vehicle, consider that wait times may fluctuate based on global component availability. It is wise to inquire with your dealer about current stock levels rather than relying on standard delivery estimates.
The takeaway
The intersection of AI, defense, and electric vehicle production means your next car purchase may be tied to global industrial resource allocation. Monitor local dealer inventory trends closely if you are shopping for a new vehicle in the near future.
