What Happened
SEAT & CUPRA has started series production of battery systems at its Martorell plant in Spain. The batteries will power the CUPRA Raval and the Volkswagen ID.Polo, both to be produced at this facility. The start of operations follows the plant's inauguration in December 2025 and is the final step before series production of the CUPRA Raval, which is expected to launch this summer.

“The start of production of series assembly battery systems marks a decisive milestone in the final stretch of the transformation of our company and takes us closer to the series production of the CUPRA Raval.”
The battery systems use the Volkswagen Group’s Unified Cell technology, which enables scalability across brands and regions. The E Box, the electronic control unit, is manufactured at SEAT & CUPRA’s El Prat Components facility. The battery assembly plant covers 64,000 m² and employs 500 people, with 11,000 solar panels providing 70% of its electricity.
Why this matters
This milestone supports local battery production in Europe, enabling the launch of affordable electric models like the CUPRA Raval and Volkswagen ID.Polo, and strengthens Martorell as a flexible plant.
