Constellium, the Paris-based aluminium business, has joined "Project M-LightEn," a bold initiative to create ultra-lightweight, sustainable vehicle chassis structures. Over the next three years, the consortium will work to revolutionise unibody vehicle architecture, targeting a 50 per cent reduction in carbon intensity and a 25 per cent decrease in weight.

Led by the Gordon Murray Group (GMG) and backed by Innovate UK and the Advanced Propulsion Centre (APC), the project brings together Constellium, Carbon ThreeSixty, and Brunel University London. As part of Project M-LightEn, Constellium will provide ultra-high-strength aluminium solutions composed of 80 per cent recycled UK consumer scrap.
"Alongside Gordon Murray Automotive's niche supercar application, Project M-LightEn will enable decarbonisation across the wider automotive industry by shortening and de-risking the path to market for innovative new materials and processes," stated GMG's Strategy and Business Director, Jean-Phillipe Launberg.
These advanced materials will serve as the backbone of the unibody structure, improving structural integrity while minimising weight and carbon emissions. In collaboration with Constellium, Brunel University London will lead advanced material research and testing, ensuring each component meets the highest performance and sustainability standards.
The initial phase of Project M-LightEn is in progress, centred on discovering new materials and refining joining techniques. By late 2027, the consortium's innovations are anticipated to enter low-volume commercial production, paving the way for wider adoption in mainstream manufacturing.
"Through Project M-LightEn, Constellium reaffirms its commitment to pushing the boundaries of lightweight technologies," said Martin Jarrett, Director of Technology and Innovation at Constellium's AS&I business unit. "This initiative allows us to develop cutting-edge aluminium solutions that redefine vehicle performance while combining innovation with sustainability and circularity."
