In the last years the research activities in the field of lightweighting have been advancing rapidly. The introduction of innovative materials and manufacturing technologies has allowed significant weight reduction. Despite this, novel technologies and materials have not reached a wide distribution. The reasons for this are mainly high production costs and environmental impacts of manufacturing that do not compensate benefits during operation. The AffordabLe LIghtweight Automobiles AlliaNCE (ALLIANCE) project has the goal of developing novel advanced materials and production technologies, aiming at an average 25% weight reduction over 100k units/year, at costs of <3 €/kg. The project will develop a mass-optimizer software tool and a multi-parameter design optimization methodology, aimed at accelerating the pre-assessment of innovative lightweight solutions and technologies over the current design procedures. Within the project, the focus of Work Package 1 (WP1) is estimating the full attributes of innovative design solutions from a Life Cycle (LC) perspective by assessing costs, energy demand and GWP over the entire vehicle LC: production, use and End-of-Life. WP1 will develop also a database to store technology use cases developed within the project through the involvement of external partners. The correlation of vehicle assessment model and technology database will facilitate the evaluation and optimization of technologies in order to achieve the overall targets of the project. Finally, WP1 will apply the optimized set of technologies to the reference vehicle to validate the impact. After an overview on project consortium and structure, the paper deals with the description of the design strategies which have been developing in order to achieve the expected targets. Additionally, the preliminary results of WP1 regarding the environmental and economic assessment are presented.
