In 2009, the prototype of a light body shell was unveiled at Wolfsburg, the final result of the European SuperLightCar project, in which C.R.F. and Comau jointly developed the assembly process for the concept car, reconciling technological feasibility and product engineering for mass production. The challenging objective for this four-year project, coordinated by Volkswagen with the participation of 38 partners (including the main European OEMs), was to reduce the weight of a standard body shell by 35%, which was achieved through extensive use of multi-material structures based on the performance and stylistic characteristics required: high-resistance steel, aluminium, magnesium (both in cast and sheet form) and thermoplastics (pressed and pultruded) combined using innovative welding, adhesive bonding and mechanical joining technologies.
