Seat and Cupra have officially opened a battery-system assembly plant in Martorell, a project developed under Volkswagen Group’s strategy to strengthen Spain’s position as one of Europe’s electromobility hubs. The facility is set to focus exclusively on series production of new models starting in 2026, which clearly signals a move from pilot runs to full-scale manufacturing.

The investment amounts to 300 million euros, with the complex covering 64,000 square meters. Its line is configured to build one battery pack every 45 seconds—up to 1,200 units per day and around 300,000 a year. From 2026, the plant will supply battery systems for the Cupra Raval and the VW ID. Polo. Packs will move to the assembly hall via an automated 600-meter bridge, an elegant piece of logistics that underlines the push for efficiency and flow.

The facility uses MEB+ battery systems with a unified cell, a compact cell-to-pack layout, and support for lithium iron phosphate chemistry. Volkswagen says this approach is designed to lower costs, improve scalability, and reduce reliance on external suppliers. In total, the Group has invested about 10 billion euros in transforming its Spanish operations, including 3 billion earmarked for Martorell’s electrification. At the same time, the plant remains flexible, able to produce electric, hybrid, and traditional models for various Group brands—an approach that hedges demand shifts while keeping choices open for future product mixes.
