Delray Beach, FL, Sept. 23, 2026 (GLOBE NEWSWIRE) -- MarketsandMarkets™ projects the EV Assembly Market is expected to reach USD 291.39 billion by 2035, from USD 190.11 billion in 2026, with a CAGR of 4.9%. Leading EV manufacturers are increasingly balancing vertical integration with strategic outsourcing to optimize production costs, supply chain control, and manufacturing flexibility. Companies such as Tesla and BYD have expanded in-house production of batteries, electric motors, power electronics, and software systems, while other OEMs continue to rely on specialized suppliers for select components. Manufacturing efficiency is also improving through advanced production strategies. For instance, Tesla's unboxed manufacturing approach is designed to reduce factory footprint by more than 40%, lowering capital expenditure and simplifying vehicle assembly operations. China has emerged as the primary EV manufacturing hub due to its integrated battery and component supply chain, while North America and Europe are accelerating the localization of battery cells, battery packs, motors, and power electronics to reduce import dependence and strengthen supply chain resilience. At the manufacturer level, they are adopting flexible multi-model production lines capable of assembling EVs, hybrids, and conventional vehicles on the same platform, improving factory utilization, reducing capital expenditure, and enabling faster responses to change in market demand.

Why This Market Matters
The shift toward electric mobility is changing how vehicles are designed, manufactured, and assembled. Automakers are increasingly moving to dedicated EV platforms, software-defined architectures, and integrated battery and powertrain systems to reduce manufacturing complexity and scale production efficiently. At the same time, rising investments in gigacasting, smart factories, automation, and battery integration are helping OEMs reduce production costs, improve quality, and accelerate EV launches. This transformation is making advanced assembly capabilities a critical factor in the competitiveness of EV manufacturers.
Market Overview
The EV assembly market is projected to grow from USD 190.11 billion in 2026 to USD 291.39 billion by 2035, at a CAGR of 4.9%. Growth is being supported by the adoption of dedicated EV platforms, software-defined vehicle architectures, automated production systems, and localized battery manufacturing ecosystems. Passenger cars are expected to dominate the market, while BEVs are projected to register the highest CAGR among propulsion types. Asia Pacific is expected to lead the market, supported by its concentration of EV production facilities, battery manufacturing capacity, integrated supply chains, and advanced manufacturing technologies such as gigacasting and Cell-to-Pack integration.
Analyst Perspective
The evolution of EV assembly reflects a shift from conventional vehicle manufacturing toward highly automated, digitally connected production ecosystems. Dedicated platforms allow manufacturers to standardize components and share architectures across multiple models, while zonal electrical architectures can reduce ECU and wiring complexity. At the factory level, robotics, AI-enabled inspection, automated material handling, autonomous mobile robots, and Manufacturing Execution Systems are improving production visibility and consistency. For OEMs, competitive differentiation is therefore moving beyond vehicle design toward the ability to combine platform standardization, battery integration, smart manufacturing, and flexible production at scale.

Segment Analysis
Battery electric vehicles (BEVs) are expected to lead the EV assembly market over the forecast period, driven by the industry's growing focus on dedicated EV platforms and large-scale manufacturing investments. Major OEMs, including Volkswagen, BMW, Hyundai, BYD, Geely, and Stellantis, are standardizing production around BEV-specific architectures such as MEB, Neue Klasse, E-GMP, e-Platform 3.0, SEA, and STLA, enabling higher production efficiency and greater economies of scale. For instance, in May 2026, Stellantis introduced STLA One, a modular vehicle platform. The platform features a scalable architecture with standardized interfaces, helping reduce development complexity, accelerate vehicle development, and improve manufacturing efficiency. STLA One is expected to deliver up to 20% cost savings through its modular design and flexible battery options. The platform will support B-, C-, and D-segment vehicles and is scheduled for commercial deployment in 2027. Manufacturers are also investing heavily in BEV-focused assembly plants, gigafactories, and battery integration facilities. Similarly, platform sharing across multiple vehicle models and brands, combined with the adoption of software-defined vehicle architectures and centralized computing systems, is increasing production scalability and manufacturing sophistication. The dominance of BEVs is further supported by the continued expansion of production capacity across China, Europe, and North America, along with significant investments in dedicated production lines, battery integration facilities, and next-generation vehicle architectures, which collectively generate substantial manufacturing value across the EV production ecosystem.
Regional Analysis
Asia Pacific is expected to lead the EV assembly market over the forecast period, driven by a strong concentration of EV production facilities, battery manufacturing capacity, and integrated supply chains.
