Seat & Cupra opens new EV battery assembly plant in Martorell

Seat & Cupra has put its electric vehicle battery system assembly plant into operation at the Martorell factory, as part of the Volkswagen Group’s overall battery strategy balancing both in-house and third-party cell supply.

Built in just over two years with an investment of €300 million, the battery system assembly plant is a key facility in Martorell’s transformation towards electrification.

It covers an area of 64,000 square metres and has the capacity to assemble one battery system every 45 seconds, amounting to 1,200 battery systems per day and 300,000 per year.

From 2026 onwards, it will exclusively supply the production lines of the Cupra Raval and the Volkswagen ID. Polo, transporting the battery systems automatically to the assembly workshop via a 600-metre bridge.

This unique solution, together with the 11,000 solar panels on the roof, which will provide 70 per cent of the electricity required for the battery systems assembly process, helps reduce the carbon footprint and ensures more sustainable and competitive production.

In addition, a water collection system with a capacity equivalent to three Olympic swimming pools, will reinforce the plant’s commitment to resource efficiency and comprehensive sustainability.
