The Eureka Lightweighting Call 2026 supports international R&D projects in lightweight design, advanced materials, recycling, joining, additive manufacturing, and digitalisation. Building on strong growth from previous editions, the 2026 call runs from 6 May to 8 October 2026 and targets mobility‑focused innovation. Funding levels range up to 80% for SMEs and 55% for large enterprises, with consortia requiring at least one company and one partner from participating countries. The program aims to align policies, accelerate technology transfer, and strengthen sustainable, resource‑efficient manufacturing across Europe.
